Abstract

A transaction card having a self-programming region that allows periodic update of security data is disclosed. The self-programming region contains one or more self-programming components, each of which can be switched between two states depending on the direction of an electrical current provided to the component. The self-programming components are used for updating security data such as a digital code at various time intervals as determined by an algorithm in a processor on the card.

Claims

1. A transaction card comprising:

a processor;

a magnetic stripe;

a self-programming region operatively coupled to the magnetic stripe; and

a power source connected to the processor and the self-programming region.

2. The card of claim 1, wherein the self-programming region is configured for data update at predetermined time intervals by one or more components provided on the card.

3. The card of claim 2, wherein the self-programming region further comprises:

at least one self-programming component configured to receive an electrical current from the power source in two directions, the at least one programming component having a first orientation associated with one current direction and a second orientation associated with the other current direction.

4. The card of claim 3, wherein the at least one self-programming component comprises one of an electromagnetic coil and a magnetic random access memory (MRAM) element.

5. The card of claim 3, wherein the self-programming component comprises a magnetic stripe emulator.

6. The card of claim 3, wherein the at least one self-programming component is disposed over the magnetic stripe and configured for encoding data on the magnetic stripe.

7. The card of claim 6, wherein the self-programming component is an electromagnetic coil.

8. The card of claim 7, further comprising:

at least one magnetic element of the magnetic stripe operatively coupled to the electromagnetic coil, and capable of aligning in two orientations in response to the two directions of the electrical current to the electromagnetic coil.

9. The card of claim 6, wherein the processor comprises:

a memory containing an algorithm for computing a verification code at the predetermined time intervals.

10. The card of claim 9, wherein the processor is configured for sending one or more signals to the power source to provide an electrical current to the at least one programming component for encoding the verification code.

11. The card of claim 6, wherein the processor further comprises a smart card interface.

12. The card of claim 6, further comprising a digital display coupled to the self-programming region and to the power source.

13. The card of claim 5, wherein the self-programming component is an electromagnetic coil.

14. The card of claim 5, wherein the processor comprises:

a memory containing an algorithm for computing a verification code at the predetermined time intervals.

15. The card of claim 14, wherein the processor is configured for sending one or more signals to the power source to provide an electrical current to the at least one programming component for encoding the verification code.

16. The card of claim 5, wherein the processor further comprises a smart card interface.

17. The card of claim 5, further comprising a digital display coupled to the self-programming region and to the power source.

18. A transaction card comprising:

a processor;

a self-programming region configured for data update at predetermined time intervals by one or more components provided on the card; and

a power source connected to the processor and the self-programming region.

19. The card of claim 18, wherein the self-programming region further comprises:

at least one self-programming component configured to receive an electrical current from the power source in two directions, the at least one programming component having a first orientation associated with one current direction and a second orientation associated with the other current direction.

20. The card of claim 19, wherein the at least one self-programming component comprises one of an electromagnetic coil and a magnetic random access memory (MRAM) element.
