Abstract
A combined credit and security card which incorporates one or more magnetic stripes for carrying coded security data and hidden within the card one or more r.f. tuned circuits capable of being interrogated remotely. The card when interrogated can activate security locks etc. The magnetic stripes can carry coded identification data. Externally the card can be provided with a photograph of the holder. The r.f. circuits can incorporate fusible links such that the card can be automatically cancelled when subjected to an r.f. field exceeding a predetermined strength. <IMAGE>
Description
SPECIFICATION
Combined credit and security card
This invention relates to a combined credit and security card, such as may be issued by banks or other institutions.
At present most banks issue credit cards in the form of a rectangular plastic card embossed with the holder's name, account number, card expiry date etc. The card also has a prepared writing surface upon which the card holder puts his signature. Such cards are also issued by many commercial organisations.
A more recent development is the cash dispensing card issued by some banks. This resembles a credit card externally but incorporates a strip or strips of magnetisable material carrying coded security information. There cash dispensing cards can be accepted in automatic banking terminals which not only dispense limited amounts of cash but also provide an interface for certain other common baning functions. In some cases a single card is issued to act both as a credit card and a cash dispensing card.
One problem with present day automatic banking terminals is that although they can be provided with a protective shutter mechanism over the keyboard input and the cash dispensing outlet the card reader slot must remain exposed at all times since it is necessary to insert the card to activate the shutter mechanism to expose the keyboard. The card reader slot is therefore vulnerable to vandalism which can render the entire terminal useless.
According to the present invention there is provided a combined credit and security card incorporation one or more magnetic strips for carrying coded information and one or more radio frequency responsive circuits, said strips and circuits being sandwiched between outer layers ofthe card and not visible externally.
In a preferred embodiment of the invention the r.f.
responsive circuits each comprise a tuned circuit incorporating a circuit element the characteristics of which are such that when the circuit is placed in a radio frequency field exceeding a predetermined strength of the frequency to which the circuit is tuned the circuit element is destroyed and the circuit is thereby rendered ineffective.
An embodimentofthe invention will now be described with reference to the accompanying drawing which depicts a combined credit and security card prior to the final sealing ofthe card.
The card comprises a rectangular plastics sheet 1 which, when folded in the middle will enclose r.f.
circuits. One half la of the card has printed on whet will be an outer face one or more strips 2 of magnetic
material on which can be recorded, by conventional
means, coded data. One or more r.f. tuned circuits 3
are also provided on the inner face. Each tuned circuit consists e.g. of an antenna pattern with a loop.
Depending on the frequency the circuits can be
printed in conductive ink on the plastics sheet, stamped out of foil, etched or otherwise deposited on a substrate which is placed on the plastics sheet.
Preferably the layout of the magnetic stripes and the tuned circuits is such as to leave adequate space for mechanical embossing of the finished card. When the circuits and stripes have been fabricated in position on the one half of the card and the other half 1 b is then folded over to close the card. The closed card is then sealed in a conventional manner. Alternatively the card may be formed from a number of separate laminated sheets bonded together. The magnetic stripes can be encoded with data comprising banking information, e.g. account number, security information, signature and/or voice verification reference data, date information etc. The tuned circuits can be arranged to respond to different frequencies providing controiled access functions, to operate time and attendance equipments etc.The outer surfaces of the card can carry institutional identification and/or logo, holder's photograph, holder's signature, bar coding etc.
The inclusion of r.f. responsive circuits in the card allows it to be remotely interrogated. Thus a bank cash dispensing terminal can now have all the mechanism including the card reader behind a protective shutter. The shutter is only opened when the card is presented in proximity to a radio frequency interrogating equipment. The card is then used in the normal manner. Similarly the card can be used to control access to buildings or secure areas, to operate attendance and time recording mechanisms.
Where signature or voice verification is required insertion of the card reader can cause signature or voice reference data to be entered into automated verification equipment. The holder then writes his signature on a verification tablet or speaks a predetermined phrase into a microphone, the equipment using the card entered data as a reference to verify the signature or voice.
1. A combined credit and security card incorporating one or more magnetic strips for carrying coded information and one or more radio frequency responsive circuits, said strips and circuits being sandwiched between outer layers of the card and not visible externally.
2. A card according to claim 1 wherein the r.f.
responsive circuits each comprise a tuned circuit incorporating a circuit element the characteristics of which are such that when the circuit is placed in a radio frequency field exceeding a predetermined strength of the frequency to which the circuit is tuned the circuit element is destroyed and the circuit
is thereby rendered ineffective.
3. A card according to claim 1 or 2 wherein the
r.f. circuit(s) are printed in conductive ink on one half
of a card which is subsequently folded across the
middle and sealed so that the circuits are not visible
externally.
4. A card according to claim 1 or 2 wherein the
r.f. circuit(s) are formed on a separate substrate
which is subsequently laminated with and bonded to
**WARNING** end of DESC field may overlap start of CLMS **.
