Description
BACKGROUND OF THE INVENTION
The present invention relates to identification systems.
In particular, the present invention relates to an identification
card which is used in such a system. Thus, such cards
conventionally have thereon identifying indicia which normally is
invisible but which can be rendered visible upon making use of
light beyond the visible spectrum, such as ultraviolet light or
infrared light.
In recent times systems of credit sales utilizing credit cards have
come into wide use, with such cards being used in all sorts of
establishments such as department stores, specialty shops,
restaurants, etc. Each individual has a given registration number
and a signature on the card so that when using the same an
impression is made from the card on a suitable form which the
individual signs so that his signature can be compared with that on
the identification card. Of course, individuals who own and use
such cards must first open special accounts with the organization
which carries out the credit operations. Thus, wherever a purchase
is made with the use of such a card, the establishment from which
the purchase is made will be paid by the organization which carries
out the administration of the credit system. Such payment is made
from the account of the individual with this latter credit
organization.
Such conventional systems have a definite disadvantage however, in
that it is possible for the card to become lost and used by an
unauthorized individual who need only forge the signature which is
readily visible on the card itself. Thus, the individual who
carries such a card must be very careful not to lose the same, and
of course if loss is noticed it must be immediately brought to the
attention of the administrating organization.
In the case of banks, the depositor will normally keep a bankbook
while the bank keeps the depositor's accounts in suitable ledgers
where the signature of the depositor is located. After the opening
of a deposit account with a bank, all receipts and disbursements
are based upon identification by the signature which is filed with
the bank. Thus whenever money is to be withdrawn, the depositor
must submit a copy of his signature upon the withdrawal and this
signature is compared with that on file with the bank before the
money is withdrawn. With such conventional deposit systems, it is
of course troublesome to keep on hand ledgers of the above type. A
considerable amount of effort and inconvenience is involved in
picking out the required ledger from a file so as to achieve the
necessary signature comparison before monies can be paid out.
Although computers are used to a greater extent in banks at the
present time, they have not become practical to the extent of
enabling ledgers of conventional type to be completely replaced by
computers, and the reason for this is partly because the bankbook
bears the signature of the depositor. Of course, it is customary to
render this signature normally invisible while at the bank the
signature on the bank book is placed in a light beyond the visible
spectrum which will render the signature visible, but even in such
cases it is possible for unauthorized individuals to use a lost
bank book for obtaining money in an unauthorized manner. For the
latter reasons it is not yet possible for banks to avoid the use of
conventional ledgers at least to an extent which is undesirable and
inconvenient.
Thus, it is known to use signatures for credit cards, bank books,
and the like, in such a way that the signatures are normally
invisible and can be rendered visible only by the use of light
beyond the visible spectrum such as ultraviolet light or infrared
light. Such expedients do indeed provide a partial solution to the
problem. The difficulty is, of course, that unauthorized
individuals know very well that use is made of ultraviolet and
infrared light, so that such unauthorized individuals such as those
who find a lost card of bank book, will know enough to subject to
the infrared or ultraviolet light rays, in order to determine the
normally invisible indicia which must be duplicated in order to
provide unauthorized use of the identification article. Thus, any
establishment can render the signature on a card or bank book
visible with the use of light beyond the visible spectrum in order
to make a comparison with the signature placed on a suitable form,
but this signature may very well be known previously even to
unauthorized individuals who have first subjected the
identification article to ultraviolet or infrared light rays.
In spite of these difficulties, such systems are widely used
because they enable individuals to carry on transactions without
cash and because banks can eliminate their ledgers when using such
systems to such an extent that only computers are required to give
an indication of the account of a given depositor. Thus, it is
possible for a bank to store all records including the balance on
deposit for a given depositor by way of computer tapes with a
suitable form being provided so that the depositor can enter items
such as the number of the account, the amount to be taken out or
deposited, and the signature of the client. In this latter case a
clerk of the bank will compare the normally invisible signature
with that placed on the form so that unauthorized disbursement of
money can be prevented to a large extent.
SUMMARY OF THE INVENTION
It is a primary object of the present invention to provide an
identification system, and particularly an identification card or
other article, which will provide safety against unauthorized use
of a credit card, bank book, or the like, beyond the extent which
has heretofore been possible with conventional systems of the type
referred to above.
In addition, it is an object of the invention to achieve this added
security without any change in the size or format of the
identification article, whether it be a card, bank book, etc.
Furthermore, it is an object of the invention to provide
identification articles which can be constructed either so as to
operate with reflected light or so as to operate with light which
is transmitted through the article.
Also, it is an object of the invention to provide a construction
which can easily be adapted for use with any one of several known
identification systems.
According to the invention the identifying indicia which is located
on the card or the like will include at least a portrait of the
authorized individual who uses the identification article, so that
it will be possible to utilize this portrait in connection with the
individual who presents the card or other identifying article. Of
course, the identifying indicia may also include the signature, so
that not only is identification made by way of a comparison of
signatures but also by way of a comparison of a portrait with the
individual who presents the card or other article, so that in this
way a practically foolproof safety against unauthorized use of an
identification article can be achieved. Thus, in accordance with
the invention use is made not only of a signature but also of a
portrait which will become visible only when exposed to light
beyond the visible spectrum.

DESCRIPTION OF PREFERRED EMBODIMENTS
Referring now to FIGS. 1-3, there is illustrated therein a card 1
according to the present invention. This card may be made of a body
of relatively thick paper, cardboard, synthetic resin or the like.
The identification article has identifying indicia in the form of a
signature 2, this signature being shown in print letters rather
than script for the sake of convenience only. It is to be
understood that the signature will normally be in the form of a
hand written cursive signature.
The indicia of the identification article of the invention however
is not made up only of the signature 2. It also includes a portrait
3 of the individual who is authorized to present the identification
article. Therefore when this article is presented it is possible to
make a comparison not only of signatures but also of the portrait
of the individual with the individual who presents the article.
This indicia 2, 3, which takes a form described in greater detail
below, is covered by a filter 4 designed to transmit only a given
type of light beyond the visible spectrum to the indicia 2, 3.
Thus, depending upon whether ultraviolet or infrared light is used,
the filter 4 will have the property of permitting ultraviolet or
infrared light to be transmitted through the filter so as to reach
the indicia 2, 3. In addition, the entire assembly is protected by
a transparent covering sheet or protective filter 5 which adheres
in a known manner to the body of paper or synthetic resin.
Referring to FIG. 3, the embodiment of the invention which is
illustrated therein provides an identification article which
operates with reflected light. It will be seen that the body 1 is
formed with an opening 6 which extends only partly through the body
1 so that the latter, because it is opaque, does not permit light
of any type to pass through. Within this recess or opening 6 of the
body 1 is located a sheet 7 which has the indicia 2, 3 located
thereon. This may be a sheet of paper on which the portrait 3 is
directly printed or to which a print carrying the portrait is
fixed, and the sheet itself may be adhesively fixed in the opening
6 to the body 1. The covering filter 4 extends across the entire
recess 6 so as to fully cover the entire sheet 7 with the indicia
thereon.
Thus, this reflecting type of construction may be inspected when
using rays beyond the visible spectrum to render the indicia
visible. For example it is possible to use ultraviolet rays in the
case where the signature 2 and portrait 3 are of a nature which
will enable them to become visible when exposed to ultraviolet
light. In this case the sheet 7 is made in the form of a
fluorescent plate and the filter 4 is in the form of a colored film
capable of transmitting therethrough ultraviolet light rays which
reach the sheet 7 so as to render the indicia 2, 3 visible. With
such a construction the signature 2 is in the form of an ink which
has the ability to reject or absorb ultraviolet rays. Although a
colorless and fully transparent ink is preferable because of the
greater security which will be achieved thereby, since such
colorless and fully transparent ink will certainly not be visible
under ordinary visible light rays, nevertheless it is preferred to
use an ink of a lighter color so that when the individual puts his
signature on the sheet 7 he will be able to see and recognize the
signature as he places it on the sheet. With this embodiment a
portrait 3 which forms part of the identifying indicia of the
invention may take the form of a positive film print fixed to the
sheet 7 in any suitable way. Also, the sheet 7 itself may be in the
form of a photographic printing paper which is soaked with a
fluorescent agent and on which the portrait is directly printed by
normal photographic methods.
While a construction of this latter type enables the device to be
used with ultraviolet rays, it is also possible to provide a
construction which will be capable of using reflected infrared
rays. In this case the indicia formed by signature 2 and portrait 3
are adapted to be rendered visible when exposed to infrared rays.
With such an embodiment the covering filter 4 is of the type which
is capable of transmitting only infrared rays therethrough. Thus,
the colored film which will form the filter 4 in this embodiment
will not transmit visible light rays so that the structure covered
by the filter 4 is not visible in ordinary light. With this
embodiment the sheet 7 may take the form of ordinary paper which is
adhered to the body 1 in the recess 6 thereof. The signature 2
which is placed on this paper 7 is entered with an ink which has
the capacity of absorbing infrared rays, and preferably the
portrait 3 is printed with the same ink, although it has been found
that the portrait 3 can take the form of an ordinary positive
photographic print which is fixed to the sheet 7 as by being
adhered thereto. Such an ordinary positive photographic print will
be satisfactorily recognized when infrared light is transmitted
through the filter 4 thereto. However, in this embodiment which
makes use of infrared rays it is also possible to use photographic
printing paper for the entire sheet 7. In this case the portrait is
printed directly on the sheet 7.
It is also possible to use an arrangement where both ultraviolet
and infrared rays are used simultaneously in a device where both of
these rays are simultaneously directed to a fluorescent plate so as
to render the latter nonfluorescent. With such a construction the
identifying indicia will absorb the infrared light so that the
fluorescent plate will be rendered fluorescent only at an area
thereof the configuration of which corresponds to the identifying
indicia. With such a construction the portrait 3 may take the form
of a negative photographic print which is fixed to the sheet 7.
Also in this case the sheet 7 may itself be in the form of negative
photographic film on which the portrait 3 is directly printed.
While all of the above-described embodiments shown in FIG. 1-3
operate with reflected light, it is also possible to apply the
invention to that type of article which transmits light
therethrough. Thus, with the embodiment of FIG. 4, the body 1' is
also made of paper or synthetic plastic, for example, but in this
case instead of a recess 6 the opening takes the form a cutout 9
which passes completely through the body 1' and indicated in FIG.
4. In this case instead of a sheet 7, the indicia 2, 3 is carried
by a sheet 8 which is in the form of a transparent film situated
directly in the opening 9 and framed by the body 1'. At opposite
sides of the film 8 are a pair of covering filters 4 which may have
any of the above-described characteristics so that the signature 2
and portrait 3 may be the same as those described above in
connection with an identification card of the reflecting type. The
transparent protective films 5 cover both pieces of the article of
FIG. 4, and with this article light beyond the visible spectrum is
directed through the opening 9 so as to be transmitted in this way
through the identifying card or the like in order to render the
identifying indicia 2, 3 visible.
FIGS. 5 through 8 respectively illustrate various types of
identification systems in which the article of the invention may be
used.
Referring to FIG. 5, the structure schematically illustrated
therein is adapted to utilize reflected ultraviolet light. For this
purpose an ultraviolet lamp 10 is situated in front of a reflector
11, so that light is directed through a condenser lens 12 before
reaching an ultraviolet filter 13. After passing through the filter
13 the light is reflected by a mirror 14 onto the identification
card C of the invention. This card is carried by a suitable support
15 on which the identification card of the invention has been
placed. Thus, when exposed to ultraviolet light the operator can
look directly at the card so as to see the indicia 2, 3 in the
manner described above.
FIG. 6 shows a system where the identification card is exposed to
infrared rays so as to render the identifying indicia visible. With
this system the card C is again placed on a suitable support or
loading stand 15 which has the inclined attitude shown in FIG. 6.
Infrared light from the lamp 16 is directed to the card so as to be
reflected thereby through an imaging tube 17 of known construction.
The operator by looking through an ocular at the top of the tube 17
is capable of seeing the indicia 2, 3 which is rendered visible by
being exposed to the infrared light.
In the system of FIG. 7 a plate which becomes fluorescent when
exposed to ultraviolet light will become nonfluorescent when
simultaneously exposed to infrared light. With this reflective type
of system, infrared light is provided by an infrared lamp 18 from
which the light is reflected by a system of reflectors 19 in the
manner shown schematically in FIG. 7. The card C is again carried
by the support 15 which is moved into the housing shown in FIG. 7
so as to locate the card C in the path of the infrared light. The
indicia 2, 3 in this case will absorb infrared light only where the
indicia 2, 3 is situated. The rest of the sheet 7 and that part of
the print 3 which does not carry the photograph itself will reflect
the infrared light. The reflected light is magnified by lens system
20 before being reflected to the plate 22 which becomes fluorescent
as a result of exposure to ultraviolet light from the lamp 21.
Wherever the infrared light from the lamp 18 reaches the plate 22,
the latter is rendered nonfluorescent so that only at an area of
the plate 22 corresponding to the configuration of the indicia 2, 3
will a sheet 22 remain fluorescent because only at this area will
there be exclusive exposure of the plate 22 to the ultraviolet
light from the lamp 21. At all other areas the plate 22 receives
both ultraviolet and infrared lights so as to become
nonfluorescent. The fluorescent identifying indicia can be viewed
through the window 23 in the manner indicated in FIG. 7.
Thus, all of the devices referred to above shown in FIGS. 5-7 will
operate with reflected light. Thus, the cards used in these systems
may have a construction such as that shown in FIG. 3 utilizing any
of the above-described features which operate with reflected light
beyond the visible spectrum.
However, it is also possible to utilize with the invention the
structure of FIG. 4. Thus, with the systems of FIGS. 6 and 7, for
example, it is only necessary to adapt the support 15 and the rest
of the structure to an arrangement which utilizes the infrared
light after it has passed through the article. Thus, the card 1'
need only be supported in such a way that the light beyond the
visible spectrum will pass therethrough before reaching the other
components to which the light is reflected in the case of FIGS. 6
and 7.
FIG. 8, however, shows an identification system capable of using
ultraviolet lights rays which pass through an identification card
which is of the transmissive type shown in FIG. 4. With this system
a fluorescent plate 23 is situated in the path of ultraviolet light
rays which are transmitted from the lamp 10 and the reflector 11
through the card C. Thus, the elements 10 and 11 of FIG. 8
correspond to the elements 10 and 11 of FIG. 5 and direct
ultraviolet rays to the identification article. The structure of
FIG. 8 is situated in a suitable housing provided with a window 23
through which it is possible to observe the card C so as to
recognize the indicia 2, 3 rendered visible by passage of
ultraviolet light through the identifying device. However, this
plate 23 of FIG. 8 can also take the form of a fluorescent plate
situated in the path of the ultraviolet rays so as to be rendered
fluorescent in a manner which will make the signature 2 and
portrait 3 recognizable.
It is thus apparent from the above description that with the
invention the identification card or the like, in addition to
having a signature of the authorized individual, also has a
portrait of the authorized individual fixed to or printed directly
on the sheet which carries the signature, with the identifying
indicia 2, 3 being covered by a covering filter in such a way that
the signature 2 and portrait 3 can be recognized only when exposed
to light beyond the visible spectrum. As a result the card of the
invention will provide a more reliable and more accurate
identification of a given individual so that there is a greater
security against any possible unauthorized use of the card either
in a bank or in any establishment which utilizes a credit card
system, as contrasted with arrangements where reliance is made only
upon a signature for the identifying indicia.
