Abstract

An electronic transaction card communicates with an add-on slot of an intelligent electronic device. The add-on slot may be a memory card slot. The intelligent electronic device may be a mobile phone or other device with or without network connectivity. The electronic transaction card may have magnetic field producing circuitry compatible with magnetic card readers, smartcard circuitry, other point-of-sale interfaces, or any combination thereof.

Claims

1. An apparatus comprising:

a stripe to communicate with a magnetic card reader; and

an interface to communicate with an intelligent electronic device;

wherein the apparatus has dimensions smaller than a credit card.

2. The apparatus of claim 1 wherein the stripe includes circuitry to produce at least one time-varying magnetic field.

3. The apparatus of claim 1 wherein the interface is compatible with an add-on slot in the intelligent electronic device.

4. The apparatus of claim 3 wherein the interface comprises a memory card interface.

5. The apparatus of claim 1 further comprising a processing element coupled to the interface and to the stripe.

6. The apparatus of claim 5 further comprising a memory element to hold programming information for the stripe.

7. The apparatus of claim 5 further comprising an embedded swipe sensor to sense when the stripe is swiped through a magnetic card reader.

8. The apparatus of claim 1 further comprising nonvolatile memory accessible by the intelligent electronic device.

9. An apparatus comprising:

means for communicating through a memory card slot in an intelligent electronic device;

means for producing at least one time-varying magnetic field to represent financial transaction data; and

means for storing the financial transaction data.

10. The apparatus of claim 9 further including software to be installed on the intelligent electronic device.

11. The apparatus of claim 10 wherein the software includes a module for single transaction account number generation.

12. The apparatus of claim 11 wherein the software is configured to run on a mobile phone.

13. The apparatus of claim 9 further comprising nonvolatile memory accessible through the means for communicating through a memory card slot.

14. The apparatus of claim 9 further comprising means to sense whether the memory card has been swiped through a magnetic card reader.

15. A memory card comprising:

a memory card slot interface; and

circuitry for producing a time-varying magnetic field compatible with a magnetic card reader.

16. The memory card of claim 15 wherein the circuitry is configured to produce a plurality of time-varying magnetic fields compatible with a point-of-sale transaction device.

17. The memory card of claim 16 further comprising nonvolatile memory accessible via the memory card slot interface.

18. The memory card of claim 15 further comprising a processing device coupled to the memory card slot interface and the circuitry for producing a time-varying magnetic field.

19. The memory card of claim 18 further comprising a software component that when executed by the processing device causes the circuitry to produce the time-varying magnetic field.

20. The memory card of claim 18 further comprising software to be transferred to a device other than the memory card.
