| Abstract | An improved credit card construction includes visible information embossed
thereon as well as the improvement of a slot having at least one
magnetizable signal carrying tab movable to a desired index position. The
credit card user places the tab in the correct index position to identify
the user of the card as the proper user. When the card is not in use, the
indexing tab is maintained in some other position in the indexing slot.
The construction eliminates misuse of the credit card since only the
proper owner knows the appropriate indexing tab position. |

BACKGROUND OF THE INVENTION
This invention relates to an improved credit card construction and, more
particularly, to a credit card construction which includes a mechanism
that eliminates unauthorized use of the credit card.
In U.S. Pat. No. 3,762,081 issued Oct. 2, 1973, to Armbruster et al. for a
Credit Card, there is disclosed a credit card construction which utilizes
slots and mechanically movable members or tabs positioned in said slots.
The members are movable to any one of a plurality of defined, index
positions. In order to use the credit card, the movable members must be
set in appropriate positions. The card is then "read" by identification
apparatus such as a cash register computer billing terminal. When not in
use the tabs are displaced from the correct "combination" positions.
The prior art credit card construction described, while providing a good
means to prevent unauthorized use of a credit card, has the disadvantage
of not being compatible with many credit card systems. Moreover, a complex
combination of numbers may necessarily need to be committed to memory.
This would be a burdensome task for the credit card user in the event he
owns a number of such cards. The present invention contemplates an
improvement over the prior art structure utilizing some of the basic
principles associated with the prior art structure.
SUMMARY OF THE INVENTION
The present invention contemplates utilization of a standard credit card
format, with embossed information on the face of the card and, optionally,
a magnetic tape attached to the card, including the improvement of a slot
with a magnetic indexing member or tab in said slot and positionable at
any one of a number of index positions. Various combinations of slots and
indexing members are disclosed.
It is thus an object of the present invention to provide an improved credit
card construction.
It is a further object of the present invention to provide a credit card
construction incorporating features of many presently available credit
cards and also providing the additional feature of a construction that
prevents unauthorized use of the credit card.
It is another object of the present invention to provide a credit card
structure having an index member associated with a slot therein. The index
member is settable to any one of a number of index positions, one index
position serving to identify the correct user of the credit card.
Still another object of the present invention is to provide a credit card
construction having a movable magnetic index member which may be moved to
provide an identification signal for the user of the credit card.
Another object of the present invention is to provide an improved credit
card construction having an index member translatable in a slot of that
credit card or rotatable in said credit card to provide a required
identification indexing signal.
These and other objects, advantages and features of the invention will be
set forth in greater detail in the description which follows.

DESCRIPTION OF THE PREFERRED EMBODIMENT
An embodiment of the improved credit card of the present invention is
illustrated in the figures. The invention contemplates various
permutations and selections of components illustrated in the embodiment
depicted in the figures depending upon the specific requirements of the
business which issues the credit card. Thus, the following description
will discuss all of the possible features as incorporated in the
illustrated credit card. However, it is to be understood that various
features may be eliminated or altered as described in order to achieve
additional desired functions with the credit card or eliminate various
functions thereof. To the degree possible, all of these alternatives will
be explained.
The credit card 10 is fabricated in the usual manner from a laminated
plastic material. Information included on the credit card 10 would include
that normally recorded on presently utilized credit cards. For example, a
credit card number 12 associated with the account would be included and
defined by embossed indices arranged in a series according to the
requirements of the business which issued the credit card. Additionally,
the name 14 of the credit card holder would be provided, for example, by
embossed letters. Additional information 15 such as the address of the
credit card holder or the expiration date could be included.
As shown in FIG. 2, the back panel of the credit card optionally includes a
strip of magnetic tape 16 attached thereto. One or more of these strips
may be utilized on the credit card 10 for identification purposes.
The description has so far been directed toward a credit card construction
as known in the prior art. The improvement of the present invention
includes slots 18 and 20 in the credit card 10. In the embodiment
disclosed, the slots 18 and 20 extend substantially along the length of
one side of the credit card. These slots 18 and 20 are provided with
visible indicia or indicators as at 22 spaced uniformly and serially along
one or both edges. Any desired combination of indicators or indicia 22 may
be utilized for this purpose.
Optionally, openings 24 are provided through the credit card 10 adjacent
each indicia 22. These openings 24 are for the purpose of optical reading
of the credit card. This will be discussed in greater detail below.
Positioned in slots 18 and 20 are one or more indexing members or tabs 26.
The tabs 26 are slidable in the slots 18 and 20 and may be indexed at any
desired position adjacent one of the indicia 22. As shown in FIG. 4, slot
18 may include indexing indentations 28 adjacent the indicia 22. The
indentations 28 cooperate with a connecting link 30 in FIG. 3 of the tab
26.
Link 30 may include flats on its slot engaging sides to prevent rotation of
the tab 26. Alternatively, the tab 26 may be rotatable in order to adjust
that tab 26 to a desired precise orientation. A tab handle member 32
extends from a top flange 34 of the tab 26 for purposes of movement and
reorientation of the tab 26. That is, handle member 32 may be grasped to
slide the tab 26 or to rotate the tab 26 depending upon the configuration
of the link 30.
The top flange 34 maintains the tab 26 in fixed relation in the slot 18
preventing withdrawal of the tab from the slot. Top flange 34 thus acts in
cooperation with bottom flange 36 to prevent removal of the tab 26 from
the slot 18.
Magnetic tape material 38 in the nature of a permanent magnet as known to
those in the art is provided on the bottom surface of flange 36.
Alternatively, bottom flange 36 may, itself, be constructed of a magnetic
material to provide a magnetic signal indicating that the tab 26 is
positioned adjacent a particular indicia 22 in a slot 18, 20. It is
possible to have the entire bottom flange 36 or a portion thereof
fabricated from magnetic material or coated with a tape material 38. In
FIG. 3, only a portion of the flange 36 is covered with tape material to
provide a magnetic signal. The opposite or uncovered portion of the flange
36 does not provide any particular signal, but acts as a neutral portion
of the tab 32.
The top flange 34 of the tab 26 and, in particular, the top surface thereof
may be color coded. Thus, a different color may be provided on opposite
sides of the handle member 32. This serves as an additional means for
increasing combinations of settings of indicia for tabs 26 in the slots 18
and 20.
The credit card structure of the present invention can be utilized in a
number of ways in combination with various types of credit check
equipment. That is, in the past, printed listings have been utilized to
verify that a credit card was not reported as stolen or missing. With the
structure of the present invention, the credit card number 12 serves to
imprint a receipt. Additionally, the credit card user would establish his
authenticity or authority by positioning tabs 26 appropriately in the
slots 18 and 20.
Thus, one or more tabs would be positioned opposite an appropriate indicia
22 known only to the true credit card owner and user. This indicia need
only be a single number and, thus, would involve a single tab associated
with a single slot. It would be quite easy for the true credit card owner
to remember the particular indicia to which the tab 26 should be set. The
necessity of remembering a complex combination of indicia would not be
necessary.
Since the tab 26 includes magnetic material 38, a signal source is
associated with the adjacent indicia 22. The position of tab 26 would be
sensed by appropriate sensing equipment such as a pair of coils between
which the magnetic material is passed. The signal derived from the
position of the tab 26 in the slot 18 could then be identified as that
associated with the correct credit card owner so long as the tab is in the
"right" position.
Magnetic coding strips 16 are attached to the back side of the credit card
10 could contain instructions for identifying the proper indicia to which
the tabs 26 should be set. This identifying information could be read by a
terminal device in which the card is placed in order to trigger a light or
other indicator. If a light were operated, it could shine through the
appropriate opening 24 and if the opening 24 was associated with tab 26 a
confirmation would be provided that the credit card owner is authentic and
has authority to use the card.
Another arrangement provides that the signal from the magnetic strip 16
would be directed to a central computer and information storage center.
The computer could verify the credit card number as well as the
authenticity of the user by the setting of tabs 26.
Tabs 26 of appropriate construction may be rotated to an appropriate
position and thus provide an input signal that will identify the credit
card user. Thus, the tab 26 can be translated laterally in the slot 18 or
rotated in that slot to provide a proper combination of movement and
positioning of the tab 26 relative to the slot 18, thereby identifying the
credit card user as the true owner of the credit card.
In the event the card is stolen or misplaced and used by an unauthorized
person, that person would not know the correct combination and positioning
of the tabs 26 relative to various indicia 22. The misuse of the card
would be immediately sensed by appropriate card readers. Delay associated
with dissemination of stolen credit card information to various businesses
would be avoided.
Additionally, by the improved credit card construction of the present
invention, a complex combination of multiple indicia need not be committed
to memory by the credit card user. All that need to be recalled is a
single indicia or a small number of indicia. Thus, it will be possible to
utilize the total credit card number and card system developed and now
used by many business without seriously altering that system. The
improvement of the invention merely adds a safeguard system to prevent
unauthorized use of the credit card.
Note also that the handle member 32 will project slightly above the surface
of the credit card 10. The handle member 32 will thus serve as an
additional record on the credit card receipt of the position of the tab 26
inasmuch as the credit card number 12, name 14 and other embossed
information thereon will be embossed upon the customer's receipt along
with an embossment from the use and position of the tab 26 and, in
particular, the handle member 32 thereof. This will provide an additional
check of the proper utilization of the indicia of the credit card and will
disclose upon return thereof to the main office of the billing company
that the sensing devices associated with the credit card construction of
the present invention are operating properly or, alternatively, that the
credit card is being misused by employees or businesses who accept the
credit card.
Therefore, while in the foregoing there has been presented a preferred
embodiment of the present invention, it is to be understood that the
invention shall be limited only by the following claims and their
equivalent constructions.
