Description
TECHNICAL FIELD
[0001] The technology disclosed herein pertains to financial card
display, and more particularly to allowing a user device to access
high-quality, redacted card art.
BACKGROUND
[0002] In a conventional digital wallet application, the user
computing device does not display the art associated with the
physical payment account. The art may be a representation of the
face of a physical card that is typically associated with the
payment instrument, such as a credit card. Some physical cards have
art that varies based on the level of the user. For example, a user
that has a higher credit level with a credit card may have a "gold"
or "platinum" credit card, and the associated physical card can
have art associated with the different levels. Physical loyalty
cards can have similar levels of art associated with the user
status. Other physical cards can have varying card art.
[0003] If a digital wallet application attempts to obtain and
display an image of the user card, the image may contain personal
user information such as the name of the user and the user
identification number.
[0004] Conventional digital wallet applications do not al low a
user to access the payment instrument art during an optical scan of
a physical card and then display appropriate art on the user
computing device.
SUMMARY
[0005] The technology of the present disclosure includes
computer-implemented methods, computer program products, and
systems to provide improved card art for display. Providing
improved card art for display comprises receiving, by one or more
computing devices, an image of a card; performing an image
recognition algorithm on the image; identifying images represented
on the card image; comparing the identified images to an image
database; determining a standard card art image associated with the
identified image based at least in part on the comparison;
associating the standard card art image with an account of a user,
the account being associated with the card in the image; and
displaying the standard card art as a representation of the
account.
[0006] These and other aspects, objects, features, and advantages
of the example embodiments will become apparent to those having
ordinary skill in the art upon consideration of the following
detailed description of illustrated example embodiments.

DETAILED DESCRIPTION OF THE EXAMPLE EMBODIMENTS
Overview
[0013] Embodiments herein provide computer-implemented techniques
for allowing a user to display card art on a user computing device.
An optical character recognition ("OCR") application receives a
scan or other image from a camera and stores the image. The OCR
application extracts the card information using an OCR algorithm
for use in a digital wallet application module, a point of sale
("POS") terminal transaction, or other suitable use. The user may
desire to display an image of the physical card on the user
computing device, a POS terminal, an online transaction website, or
on any suitable user interface. The OCR application may use the
image from the OCR process to prepare a card image. The displayed
card art may be a redacted version of the card image. The displayed
card art may alternatively be a high quality version of the card
art that is obtained from the issuer of the card or another
suitable location.
[0014] Throughout the specification, the general term "card" will
be used to represent any type of physical card instrument, such as
a magnetic stripe card, or a representation thereof, such as a card
displayed on a screen or piece of paper. In example embodiments,
the different types of card represented by "card" can include
credit cards, debit cards, stored value cards, loyalty cards,
identification cards, or any other suitable card representing an
account of a user or other information thereon. Examples using
cards may be applied to the images of other items, such as
receipts, boarding passes, tickets, and other suitable items. In
certain examples, the card may be a facsimile of a card, such as a
photocopy or an image on a display screen.
[0015] The user may employ the card when making a transaction, such
as a purchase, ticketed entry, loyalty check-in, or other suitable
transaction. The user may obtain the card information for the
purpose of importing the account represented by the card into a
digital wallet application module of a computing device or for
other digital account purposes. The card is typically a plastic
card containing the account information and other data on the card.
In many card embodiments, the customer name, expiration date, and
card numbers are physically embossed on the card. The embossed
information is visible from both the front and back of the card,
although the embossed information is typically reversed on the back
of the card.
[0016] A user may desire to enter the information from the card
into a user computing device or other computing device, for
example, to conduct an online purchase, to conduct a purchase with
a mobile computing device or other computing device, to add the
information to a wallet application on a computing device, or for
any other suitable reason. In an example, the user desires to use a
mobile computing device to conduct a purchase transaction using a
digital wallet application module executing on the mobile computing
device. The digital wallet application module may require an input
of the details of a particular user payment account to conduct a
transaction with the particular user payment account or to set up
the account. Due to the small screen size and keyboard interface on
a mobile device, such entry can be cumbersome and error prone for
manual input. Additionally, a merchant system may need to capture
card information to conduct a transaction or for other reasons.
[0017] In addition to account identifiers, the front of the card
typically contains one or more of logos of the issuer of the card,
pictures chosen by the user or the issuer, other text describing
the type or status of the user account, a security code, and other
marketing and security elements, such as holograms or badges. The
user name, card expiration date, and the account identifier, such
as a credit card number, may be embossed on the front of the card
such that the information protrudes from the front of the card.
[0018] The user employs a mobile phone, digital camera, or other
user computing device to capture an image of the card associated
with the account that the user desires to input into the user
computing device.
[0019] An OCR application on the user computing device receives the
image of the card. The image may be obtained from the camera module
of a user computing device, such as the camera on a mobile phone.
The image may be obtained from a scanner coupled to the user
computing device or any other suitable digital imaging device. The
image may be obtained from video captured by the user computing
device. The image may be accessed by the OCR application on the
user computing device from a storage location on the user computing
device, from a remote storage location, or from any suitable
location. All sources capable of providing the image will be
referred to herein as a "camera."
[0020] An OCR application receives the images of the card from the
camera. The functions of the OCR application may be performed by
any suitable module, hardware, software, or application operating
on the user computing device. Some, or all, of the functions of the
OCR application may be performed by a remote server or other
computing device, such as the server operating in an OCR system.
For example, a digital wallet application module on the user
computing device may obtain the images of the card and transmit the
images to the OCR system for processing. In another example, some
of the OCR functions may be conducted by the user computing device
and some by the OCR system or another remote server. Examples
provided herein may indicate that many of the functions are
performed by an OCR application on the user computing device, but
some or all of the functions may be performed by any suitable
computing device.
[0021] In certain example embodiments, the image is presented on
the user interface of the user computing device as a live video
image of the card while the user manipulates the camera of the
computing device to capture the digital image of the card. The OCR
application can isolate and store one or more images from the video
feed of the camera. For example, the user may hover the camera
function of a user computing device over a financial card and
observe the representation of the financial card on the user
interface of the user computing device.
[0022] The OCR application may perform the OCR process by any
suitable processing. The OCR application may extract information
from the card, such as the user account number, the user name, the
expiration date, or other suitable information. The information
from the card may be stored and/or uploaded for use by a digital
wallet application module, a POS terminal, an online wallet
account, or any suitable user.
[0023] The user may use the extracted information to conduct a
transaction with a merchant system. For example, the user may open
the OCR application and select a payment account to use in the
transaction.
[0024] To make the process of selecting a payment account easier
and more accurate, the OCR application may display the card art
associated with the payment account. The card art is obtained from
the received images from the OCR process or from a provider of
substitute card art.
[0025] The OCR application may use one of the stored images from
the OCR process to obtain the card art or the OCR application may
obtain a new image as described herein. The OCR application selects
the clearest and least blurry image available. The clearest image
might have the least bright spots and the most contrast to make the
card art easily discernable. In another example, at the time of the
OCR process, the OCR application or the user may flag an image as a
candidate image for the card display.
[0026] The OCR application crops the image to display the full
card. While the OCR application may have cropped the image to
isolate the data on the card during the OCR process, the OCR
application may now crop the image to display the full body of the
card.
[0027] The OCR application saves the cropped image in a storage
location on the user computing device or in another suitable
storage location.
[0028] While displaying the image of the card, the user account
information also may be visible on the card. If a person other than
the user opened the digital wallet, the user account information
would be visible on the face of the card image. Thus, the OCR
application redacts the information on the card image to protect
the privacy of the user. For example, the user account number and
the user name may be obscured either partially or entirely to
protect the privacy of the user account.
[0029] The OCR application determines during the OCR process where
the digits are located and the categories of the groups of digits.
For example, the OCR application may extract the digits of the user
account number and categorize the group of digits as the user
account number.
[0030] The user, the OCR system, the payment processing system, or
other suitable party may instruct the OCR application which data
should be obscured when displaying the card. For example, the user
may enter information in a user interface on the user computing
device to obscure the account number and the user name from the
image of the card. In certain examples, the selection of
information to obscure may be performed automatically by the OCR
application.
[0031] The OCR application may obscure the data on the card image
in any suitable manner. For example, the data may be erased,
pixilated, blurred, darkened, or in any manner altered to prevent
the data from being read via the displayed card image. In an
example, the OCR application presents the obscured image to the
user for approval. The user may verify that the data on the card is
sufficiently obscured, that the card is still identifiable after
the obscuring, or verify any other aspect of the card image. The
user may indicate an acceptance or rejection of the image.
[0032] The image may be displayed as a representation of the card
or the financial account. The image may be used at any time that a
representation of the card is required. For example, a digital
wallet application module may display the card when the user is
selecting a card for a purchase. An application on the user device
may display the card when the user is attempting to gain access to
an event such as a flight or a concert. An application may display
the card when the user presents the card as identification. The
card image may be transmitted to a POS terminal for display to a
merchant operator. The card image may be transmitted to an online
merchant during a transaction. The card image may be used for any
suitable purpose.
[0033] In an example embodiment, the OCR application obtains
standard, high quality, substitute card art for display. For
example, if a high quality version of the card art is available
that does not contain sensitive user data, the OCR application may
display the high quality version on the user computing device or in
other locations.
[0034] The OCR application obtains the image of the card from a
camera during the OCR process or at any suitable time. For example,
the OCR application may access a card image from a storage location
after the OCR process is completed. Any other manner of obtaining a
card image as described herein may be utilized. Before locating the
standard image, the OCR application may optionally obscure the
personal information on the image as described herein.
[0035] To obtain substitute card art, the OCR application or
another party may transmit the image of the card to an OCR system.
The OCR system performs an image recognition algorithm on the card
image. The OCR system may use any suitable algorithm, process,
method, or other manner of recognizing card images. For example,
the OCR system may isolate images, such as card art, within the
image of the card and can compare the card art images to a stored
database of images to identify matching images. The OCR system may
apply an OCR algorithm to one or more words identified in the card
art.
[0036] The OCR system identifies images, logos, words, icons,
pictures, badges, and other features of the art on the card image.
The OCR system identifies the card in the image by comparing the
identified art to a database of identified art. When the OCR system
compares the identified art to a database of images and locates a
matching image, the OCR application accesses any data stored with
the matching image.
[0037] The data stored with the matching images may include an
identification of the card type. For example, the OCR system may
identify a logo on the card image that matches a logo in the
database. The logo may be identified in the database as the logo
for a particular bank. In the example, the OCR system may identify
the card image as likely being a credit card associated with the
particular bank as the issuer of the credit card.
[0038] In another example, the OCR system may identify an image
that matches an image in the database of an icon or other logo of a
particular department store. The icon or other logo may be used to
identify the card image as likely being a gift card issued by the
particular department store.
[0039] In another example, the OCR system may identify a hologram
that matches an image in the database that is associated with a
particular credit card issuer. The OCR system may recognize the
hologram by comparing multiple images from multiple angles with
images in the image database. The multiple images may be obtained
by extracting one or more images from a continuous scan of the card
or by capturing multiple images of the card by moving the camera to
multiple angles above the card. If one or more of the images
matches the hologram, then the OCR system may identify the card as
likely being a credit card issued by the particular credit card
issuer.
[0040] The OCR system obtains a standard image for the card art.
The standard image may be any original and/or high quality card art
associated with the card in the image. For example, the OCR system
may obtain a version of the art from the issuer of the card that
has a higher resolution than the images received from the camera.
The card art may be received from the issuers of the associated
cards, from a third party card art system, or from any suitable
source. The standard image for the card art may be canonical images
provide by user. As users may upload card art, the OCR system may
obtain the uploaded images and determine that the uploaded images
are of a higher quality or have other desirable attributes.
[0041] In an example, the OCR system may maintain a database of
high quality card art. The card art database may be populated by
the OCR system. The card art may be updated on a regular basis to
maintain current art for some or all of the issuers of the
cards.
[0042] In another example, the OCR system may obtain the card art
at the time of the analysis of the image. That is, when the OCR
system recognizes the card art associated with the image, a request
may be transmitted to the issuer of the card or another suitable
party for a standard copy of the card art.
[0043] In another example, the OCR application transmits the user
account information to the OCR system to allow the OCR system to
identify the card art. The user account information may be any
information necessary to allow the OCR system to identify the card
art associated with the card. For example, the first four or six
digits of the user account number may be sufficient to allow the
OCR system to identify the associated card art. The OCR system may
use any other suitable information to identify the card art. The
transmitted information may be used to find a suitable match in the
database of standard art. The standard art may be obtained from the
database or from an issuer of the card.
[0044] The OCR system transmits the high quality card art to the
OCR application or another application on the user device, such as
a digital wallet application module. The OCR application, the
digital wallet application module, a POS terminal, or any suitable
computing system displays the card art at any time that a
representation of the card is needed as described herein.
Example System Architecture
[0045] Turning now to the drawings, in which like numerals
represent like (but not necessarily identical) elements throughout
the figures, example embodiments are described in detail.
[0046] FIG. 1 is a block diagram depicting a system for extracting
financial account information with relaxed card alignment and for
extracting financial account information from multiple cards, in
accordance with certain example embodiments. As depicted in FIG. 1,
the system 100 includes network computing devices 110, 120, 140,
and 170 that are configured to communicate with one another via one
or more networks 105.
[0047] Each network 105 includes a wired or wireless
telecommunication means by which network devices (including devices
110, 120, 140, and 170) can exchange data. For example, each
network 105 can include a local area network ("LAN"), a wide area
network ("WAN"), an intranet, an Internet, a mobile telephone
network, or any combination thereof. Throughout the discussion of
example embodiments, it should be understood that the terms "data"
and "information" are used interchangeably herein to refer to text,
images, audio, video, or any other form of information that can
exist in a computer-based environment.
[0048] Each network computing device 110, 120, 140, and 170
includes a device having a communication module capable of
transmitting and receiving data over the network 105. For example,
each network device 110, 120, 140, and 170 can include a server,
desktop computer, laptop computer, tablet computer, a television
with one or more processors embedded therein and/or coupled
thereto, smart phone, handheld computer, personal digital assistant
("PDA"), or any other wired or wireless, processor-driven device.
In the example embodiment depicted in FIG. 1, the network devices
110, 120, 140, and 170 are operated by end-users or consumers, OCR
system operators, payment processing system operators, and card
issuer operators, respectively. In certain embodiments, the various
operators may have to download an application, activate a feature
of an application, and/or otherwise enable an application to take
advantage of the features described herein.
[0049] The user 101 can use the communication application 112,
which may be, for example, a web browser application or a
stand-alone application, to view, download, upload, or otherwise
access documents or web pages via a distributed network 105. The
network 105 includes a wired or wireless telecommunication system
or device by which network devices (including devices 110, 120,
140, and 170) can exchange data. For example, the network 105 can
include a local area network ("LAN"), a wide area network ("WAN"),
an intranet, an Internet, storage area network (SAN), personal area
network (PAN), a metropolitan area network (MAN), a wireless local
area network (WLAN), a virtual private network (VPN), a cellular or
other mobile communication network, Bluetooth, NFC, or any
combination thereof or any other appropriate architecture or system
that facilitates the communication of signals, data, and/or

111 or may open in the communication application 112. The interface
can allow the user 101 to configure the OCR application 115 and the
user account on the offer provider system 150.
[0053] The OCR application 115 can be used to analyze a card and
extract information or other data from the card. The OCR system 120
or other system that develops the OCR algorithms or other methods
may include a set of computer-readable program instructions, for
example, using JavaScript, that enable the OCR system 120 to
interact with the OCR application 115.
[0054] Any of the functions described in the specification as being
performed by the OCR application 115 can be performed by the
payment processing system 140, the OCR system 120, the user
computing device 110, a merchant system (not pictured) or any other
suitable hardware or software system or application.
[0055] The user device 110 includes a data storage unit 113

obtaining individual images or a video scan. Any other suitable
image capturing device may be represented by the camera 114.
[0057] The payment processing system 140 includes a data storage
unit 147 accessible by the web server 144. The example data storage
unit 147 can include one or more tangible computer-readable storage
devices. The payment processing system 140 is operable to conduct
payments between a user 101 and a merchant system (not pictured).
The payment processing system 140 is further operable to manage a
payment account of a user 101, maintain a database to store
transactions of the merchant system and the user 101, verify
transactions, and other suitable functions.
[0058] The user 101 may use a web server 144 on the payment
processing system 140 to view, register, download, upload, or
otherwise access the payment processing system 140 via a website
(not illustrated) and a communication network 105). The user 101
associates one or more registered financial card accounts,
including bank account debit cards, credit cards, gift cards,
loyalty cards, coupons, offers, prepaid offers, store rewards
cards, or other type of financial account that can be used to make
a purchase or redeem value-added services with a payment account of
the user 101.
[0059] A card issuer, such as a bank or other institution, may be
the issuer of the financial account being registered. For example,
the card issuer may be a credit card issuer, a debit card issuer, a
stored value issuer, a financial institution providing an account,
or any other provider of a financial account. The payment
processing system 140 also may function as the issuer for the
associated financial account. The user's 101 registration
information is saved in the payment processing system's 140 data
storage unit 147 and is accessible the by web server 144. The card
issuer employs a card issuer computing system 170 to issue the
cards, manage the user account, and perform any other suitable
functions. The card issuer system 170 may alternatively issue cards
used for identification, access, verification, ticketing, or cards
for any suitable purpose. The card issuer system 170 may employ a
web server 174 to manage the user account and issue cards 102.
[0060] The OCR system 120 utilizes an OCR system web server 124
operating a system that produces, manages, stores, or maintains OCR
algorithms, methods, processes, or services. The OCR system web
server 124 may represent the computer implemented system that the
OCR system 120 employs to provide OCR services to user computing
devices 110, merchants, or any suitable part. The OCR system web
server 124 can communicate with one or more payment processing
systems 140, a user device 110, or other computing devices via any
available technologies. These technologies may include, but would
not be limited to, an Internet connection via the network 105,
email, text, instant messaging, or other suitable communication
technologies. The OCR system 120 may include a data storage unit
127 accessible by the web server 124 of the OCR system 120. The
data storage unit 127 can include one or more tangible

[0061] Any of the functions described in the specification as being
performed by the OCR system 120 can be performed by the OCR
application 115, the user computing device 110, or any other
suitable hardware or software system or application.
[0062] The user 101 may employ the card 102 when making a
transaction, such as a purchase, ticketed entry, loyalty check-in,
or other suitable transaction. The user 101 may obtain the card
information for the purpose of importing the account represented by
the card 102 into a digital wallet application module 111 of a
computing device 110 or for other digital account purposes. The
card 102 is typically a plastic card containing the account
information and other data on the card 102. In many card 102
embodiments, the customer name, expiration date, and card numbers
are physically embossed on the card 102. The embossed information
is visible from both the front and back of the card 102, although
the embossed information is typically reversed on the back of the
card 102.
[0063] It will be appreciated that the network connections shown
are exemplary and other means of establishing a communications link
between the computers and devices can be used. Moreover, those
having ordinary skill in the art having the benefit of the present
disclosure will appreciate that the user device 110, OCR system
120, payment processing system 140, and card issuer system 170
illustrated in FIG. 1 can have any of several other suitable
computer system configurations. For example, a user device 110
embodied as a mobile phone or handheld computer may not include all
the components described above.
Example Processes
[0064] The example methods illustrated in FIG. 2-3 are described
hereinafter with respect to the components of the example operating
environment 100. The example methods of FIG. 2-3 may also be
performed with other systems and in other environments.
[0065] FIG. 2 is a block flow diagram depicting a method 200 for
displaying card art on a user computing device 110 with redacted
user information, in accordance with certain example
embodiments.
[0066] With reference to FIGS. 1 and 2, in block 205, the optical
character recognition ("OCR") application 115 on the user device
110 obtains a digital scan of a card 102. The user 101 employs a
mobile phone, digital camera, or other user computing device 110 to
capture an image of the card 102 associated with the account that
the user 101 desires to input into the user computing device
110.
[0067] The OCR application 115 on the user computing device 110
receives the image of the card 102. The image may be obtained from
the camera module of the user computing device 110, such as the
camera 114 on a mobile phone. The image may be obtained from a
scanner coupled to the user computing device 110 or any other
suitable digital imaging device. The image may be obtained from
video captured by the user computing device 110. The image may be
accessed by the OCR application 115 on the user computing device
110 from a storage location on the user computing device 110, from
a remote storage location, or from any suitable location. All
sources capable of providing the image will be referred to herein
as a "camera" 114.
[0068] The functions of the OCR application 115 may be performed by
any suitable module, hardware, software, or application operating
on the user computing device 110. Some, or all, of the functions of
the OCR application 115 may be performed by a remote server or
other computing device, such as the server operating in an OCR
system 120. For example, a digital wallet application module 111 on
the user computing device 110 may obtain the images of the card and
transmit the images to the OCR system 120 for processing. In
another example, some of the OCR functions may be conducted by the
user computing device 110 and some by the OCR system 120 or another
remote server. Examples provided herein may indicate that many of
the functions are performed by an OCR application 115 on the user
computing device 110, but some or all of the functions may be
performed by any suitable computing device.
[0069] The image is presented on the user interface of the user
computing device 110 as a live video image of the card 102. The OCR
application 115 can isolate and store one or more images from the
video feed of the camera 114. For example, the user 101 may hover
the camera 114 function of a user computing device 110 over the
card 102 and observe the representation of the card on the user
interface of the user computing device 110.
[0070] In block 210, the OCR application 115 may crop the image to
display only the desired information from the card 102. For
example, if the card 102 in the image is a credit card, the OCR
application 115 accesses information associated with the expected
location of the account number of a credit card. The expected
location may be obtained from a database of card layouts stored on
the user computing device 110 or in another suitable location.
Credit cards, driver's licenses, loyalty cards, and other cards
typically meet an industry standard or a particular issuer standard
for the data locations and the layout of the card. The standards
may be stored in the OCR application 115 or in a location
accessible by the OCR application 115. In certain circumstances,
the data locations may be provided by the issuer of the card
102.
[0071] An illustration of the card 102 displayed on the user
computing device is presented in FIG. 4.
[0072] FIG. 4 is an illustration of a user computing device 110
displaying an image of a financial card 102, in accordance with
certain example embodiments. The user computing device 110 is shown
as a mobile smartphone. The user computing device 110 is shown with
a display screen 405 as a user interface. The card 102 is shown
displayed on the user computing device 110. The card 102 is shown
displaying a name 404 and a user identification number 406. The
card 102 additionally displays a logo 410 for the card issuer
system 170, the associated bank, or any suitable party.
[0073] In block 215, the OCR application performs an OCR algorithm
on the image. The OCR application 115 performs an OCR algorithm or
other computer implemented process to determine the card
information. In an example, the OCR application 115 may use an OCR
algorithm to analyze the digit locations in the image of the card
102 to extract the account number of a credit card. The extracted
number may be presented to (or provided for display to) the user
101 for verification, stored in the OCR application 115,
transmitted to a remote computer, stored in a digital wallet
application module 111, or used in any suitable manner. Other
information, such as the name, expiration date, security code, or
any suitable information, may also be extracted from the image.
[0074] In block 220, the OCR application 115 obscures personal
information on the card image. While displaying the image of the
card 102, the user account information also may be visible on the
image. In an example, if a person other than the user 101 opened
the digital wallet application module 111, the user account
information would be visible on the face of the card image. Thus,
the OCR application 115 redacts the information on the card image
to protect the privacy of the user 101. For example, the user
account number and the name may be obscured either partially or
entirely to protect the privacy of the user account.
[0075] The OCR application 115 determines during the OCR process
where the digits are located and the categories of the groups of
digits. For example, the OCR application 115 may extract the digits
of the user account number and categorize the group of digits as
the user account number.
[0076] The user 101, the OCR system 120, the payment processing
system 140, or other suitable party may instruct the OCR
application 115 which data should be obscured when displaying the
card 102. For example, the user 101 may enter information into a
user interface on the user computing device 110 to obscure the
account number and the name from the image of the card 102. In
certain examples, the selection of information to obscure may be
performed automatically by the OCR application 115.
[0077] The OCR application 115 may obscure the data on the card
image in any suitable manner. For example, the data may be erased,
pixilated, blurred, darkened, or in any manner altered to prevent
the data from being read via the displayed card image. In an
example, the OCR application presents the obscured image to the
user for approval. The user may verify that the user data on the
card is sufficiently obscured, that the card is still identifiable
after the obscuring, or verify any other aspect of the card image.
The user 101 may indicate an acceptance or rejection of the image.
If the user rejects the image, the process may terminate or repeat
from an earlier block, such as block 205 (not pictured in FIG.
2).
[0078] In block 225, the OCR application 115 displays redacted
original card image on user interface to represent the user
account. The card image may be displayed as a representation of the
card 102 or the financial account. The card image may be used at
any time that a representation of the card 102 or account is
required. For example, a digital wallet application module 111 may
display the card image when the user 101 is selecting an account
for a purchase. An application on the user device 110 may display
the card image when the user 101 is attempting to gain access to an
event such as a flight or a concert. An application may display the
card image when the user 101 presents the card as identification.
The card image may be transmitted to a POS terminal for display to
a merchant operator. The card image may be transmitted to an online
merchant during a transaction. The card image may be used for any
suitable purpose.
[0079] FIG. 5 is an illustration of a user computing device
displaying a redacted credit card image, in accordance with certain
example embodiments. The user computing device 110 is shown as a
mobile smartphone. The user computing device 110 is shown with a
display screen 405 as a user interface. The card 102 is shown
displayed on the user computing device 110. The card 102 is shown
with the name 404 and the user identification number 406 redacted.
The card 102 displays a logo 410 for the card issuer system 170.
The logo 410 is not redacted because the logo 410 is needed for
card 102 identification, but does not provide personal user
information.
[0080] FIG. 3 is a block flow diagram depicting a method 300 for
displaying high quality images of card art on a user computing
device 110, in accordance with certain example embodiments. The OCR
application 115 obtains standard, high quality, substitute card art
for display. For example, if a high quality, generic version of the
card art is available that does not contain sensitive user data,
the OCR application may display the high quality version on the
user computing device or in other locations.
[0081] Blocks 205, 210, 215, and 220 of FIG. 3 are performed as
described in blocks 205, 210, 215, and 220 of FIG. 2.
[0082] In block 325, the OCR application 115 transmits the image to
a web server 124 of the OCR system 120. The image may be
transmitted to the OCR system 120 via an Internet connection over
the network 105, email, text, or via any suitable technology. While
described herein as being performed by the OCR system 120, the
functions of obtaining the standard card art may be performed by
any suitable party, such as the OCR application 115, the payment
processing system 140, or the card issuer system 170.
[0083] In block 330, the OCR system 120 performs an image
recognition algorithm on the card image. The OCR system 120 may use
any suitable algorithm, process, method, or other manner of
recognizing card images. For example, the OCR system 120 may
isolate images, such as a logo, within the image of the card 102
and compare the card art images to a stored database of images to
identify matching images. The OCR system 120 may apply an OCR
algorithm to one or more words identified in the card art.
[0084] The OCR system 120 identifies images, logos, words, icons,
pictures, badges, and other features of the art on the card
image.
[0085] In block 335, the OCR system 120 identifies the card in the
image by comparing the identified art to a database of identified
art. When the OCR system 120 compares the identified art to a
database of images and locates a matching image, the OCR system 120
accesses any data stored with the matching image.
[0086] The data stored with the matching images may include an
identification of the card type. For example, the OCR system 120
may identify a logo on the card image that matches a logo in the
database. The logo may be identified in the database as the logo
for a particular bank. In the example, the OCR system 120 may
identify the card image as likely being a credit card associated
with a particular bank associated with the card issuer system
170.
[0087] In another example, the OCR system 120 may identify an image
that matches an image in the database of an icon or other logo of a
particular department store. The icon or other logo may be used to
identify the card image as likely being a gift card issued by the
particular department store.
[0088] In another example, the OCR system 120 may identify a
hologram that matches an image in the database that is associated
with a particular credit card issuer. The OCR system 120 may
recognize the hologram by comparing multiple images from multiple
angles with images in the image database. The multiple images may
be obtained by extracting one or more images from a continuous scan
of the card or by capturing multiple images of the card by moving
the camera to multiple angles above the card. If one or more of the
images matches the hologram, then the OCR system 120 may identify
the card as likely being a credit card issued by the particular
credit card issuer.
[0089] In block 340, the OCR system 120 obtains a standard image
for the card art. The standard image may be any original and/or
high quality card art associated with the card 102 in the image.
For example, the OCR system 120 may obtain a version of the art
from the card issuer system 170 that issued the card 102 that has a
higher resolution than the images received from the camera 114. The
card art may be received from the issuers 170 of the associated
cards, from a third party card art system, or from any suitable
source.
[0090] In an example, the OCR system 120 may maintain a database of
high quality card art. The card art database may be populated by
the OCR system 120. The card art may be updated on a regular basis
to maintain current art for some or all of the issuers of the cards
102.
[0091] In another example, the OCR system 120 may obtain the card
art at the time of the analysis of the image. That is, when the OCR
system 120 recognizes the card art associated with the image, a
request may be transmitted to the card issuer system 170 that
issued the card or another suitable party for a standard copy of
the card art.
[0092] In another example, the OCR application 115 transmits the
user account information to the OCR system 120 to allow the OCR
system 120 to identify the card art. The user account information
may be any information necessary to allow the OCR system 120 to
identify the card art associated with the card 102. For example,
the first four or six digits of the user account number may be
sufficient to allow the OCR system 120 to identify the associated
card art. The OCR system 120 may use any other suitable information
to identify the card art. The transmitted information may be used
to find a suitable match in the database of standard art. The
standard art may be obtained from the database or from the card
issuer system 170.
[0093] In block 345, the OCR system 120 transmits the standard card
art to the OCR application 115 or another application on the user
device 110, such as a digital wallet application module 111 for
display.
[0094] In block 350, the OCR application 115 displays the standard
card image on a user interface to represent the user account. The
card image may be displayed as a representation of the card 102 or
the financial account. The card image may be used at any time that
a representation of the card 102 or account is required. For
example, a digital wallet application module 111 may display the
card image when the user 101 is selecting an account for a
purchase. An application on the user device 110 may display the
card image when the user 101 is attempting to gain access to an
event such as a flight or a concert. An application may display the
card image when the user 101 presents the card as identification.
The card image may be transmitted to a POS terminal for display to
a merchant operator. The card image may be transmitted to an online
merchant during a transaction. The card image may be used for any
suitable purpose.

FireWire, various video buses, and the like. The I/O interface 2060
may be configured to implement only one interface or bus
technology. Alternatively, the I/O interface 2060 may be configured
to implement multiple interfaces or bus technologies. The I/O
interface 2060 may be configured as part of, all of, or to operate
in conjunction with, the system bus 2020. The I/O interface 2060
may include one or more buffers for buffering transmissions between
one or more external devices, internal devices, the computing
machine 2000, or the processor 2010.
[0102] The I/O interface 2060 may couple the computing machine 2000
to various input devices including mice, touch-screens, scanners,
electronic digitizers, sensors, receivers, touchpads, trackballs,
cameras, microphones, keyboards, any other pointing devices, or any
combinations thereof. The I/O interface 2060 may couple the
computing machine 2000 to various output devices including video
displays, speakers, printers, projectors, tactile feedback devices,
automation control, robotic components, actuators, motors, fans,
solenoids, valves, pumps, transmitters, signal emitters, lights,
and so forth.
[0103] The computing machine 2000 may operate in a networked
environment using logical connections through the network interface
2070 to one or more other systems or computing machines across the
network 2080. The network 2080 may include wide area networks
(WAN), local area networks (LAN), intranets, the Internet, wireless
access networks, wired networks, mobile networks, telephone
networks, optical networks, or combinations thereof. The network
2080 may be packet switched, circuit switched, of any topology, and
may use any communication protocol. Communication links within the
network 2080 may involve various digital or an analog communication
media such as fiber optic cables, free-space optics, waveguides,
electrical conductors, wireless links, antennas, radio-frequency
communications, and so forth.
[0104] The processor 2010 may be connected to the other elements of
the computing machine 2000 or the various peripherals discussed
herein through the system bus 2020. It should be appreciated that
the system bus 2020 may be within the processor 2010, outside the
processor 2010, or both. According to some embodiments, any of the
processor 2010, the other elements of the computing machine 2000,
or the various peripherals discussed herein may be integrated into
a single device such as a system on chip ("SOC"), system on package
("SOP"), or ASIC device.
[0105] In situations in which the systems discussed here collect
personal information about users, or may make use of personal
information, the users may be provided with a opportunity to
control whether programs or features collect user information
(e.g., information about a user's social network, social actions or
activities, profession, a user's preferences, or a user's current
location), or to control whether and/or how to receive content from
the content server that may be more relevant to the user. In
addition, certain data may be treated in one or more ways before it
is stored or used, so that personally identifiable information is
removed. For example, a user's identity may be treated so that no
personally identifiable information can be determined for the user,
or a user's geographic location may be generalized where location
information is obtained (such as to a city, ZIP code, or state
level), so that a particular location of a user cannot be
determined. Thus, the user may have control over how information is
collected about the user and used by a content server.
[0106] Embodiments may comprise a computer program that embodies
the functions described and illustrated herein, wherein the
computer program is implemented in a computer system that comprises
instructions stored in a machine-readable medium and a processor
that executes the instructions. However, it should be apparent that
there could be many different ways of implementing embodiments in
computer programming, and the embodiments should not be construed
as limited to any one set of computer program instructions.
Further, a skilled programmer would be able to write such a
computer program to implement an embodiment of the disclosed
embodiments based on the appended flow charts and associated
description in the application text. Therefore, disclosure of a
particular set of program code instructions is not considered
necessary for an adequate understanding of how to make and use
embodiments. Further, those skilled in the art will appreciate that
one or more aspects of embodiments described herein may be
performed by hardware, software, or a combination thereof, as may
be embodied in one or more computing systems. Moreover, any
reference to an act being performed by a computer should not be
construed as being performed by a single computer as more than one
computer may perform the act.
[0107] The example embodiments described herein can be used with
computer hardware and software that perform the methods and
processing functions described herein. The systems, methods, and
procedures described herein can be embodied in a programmable
computer, computer-executable software, or digital circuitry. The
software can be stored on computer-readable media. For example,
computer-readable media can include a floppy disk, RAM, ROM, hard
disk, removable media, flash memory, memory stick, optical media,
magneto-optical media, CD-ROM, etc. Digital circuitry can include
integrated circuits, gate arrays, building block logic, field
programmable gate arrays (FPGA), etc.
[0108] The example systems, methods, and acts described in the
embodiments presented previously are illustrative, and, in
alternative embodiments, certain acts can be performed in a
different order, in parallel with one another, omitted entirely,
and/or combined between different example embodiments, and/or
certain additional acts can be performed, without departing from
the scope and spirit of various embodiments. Accordingly, such
alternative embodiments are included in the invention claimed
herein.
[0109] Although specific embodiments have been described above in
detail, the description is merely for purposes of illustration. It
should be appreciated, therefore, that many aspects described above
are not intended as required or essential elements unless
explicitly stated otherwise. Modifications of, and equivalent
components or acts corresponding to, the disclosed aspects of the
example embodiments, in addition to those described above, can be
made by a person of ordinary skill in the art, having the benefit
of the present disclosure, without departing from the spirit and
scope of embodiments defined in the following claims, the scope of
which is to be accorded the broadest interpretation so as to
encompass such modifications and equivalent structures.
