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. A memory card compatible with a memory card slot in a mobile phone, the memory card including nonvolatile memory accessible by the mobile phone, and a point-of-sale interface to communicate with a point-of-sale terminal, wherein the point-of-sale interface receives power from the mobile phone.

2. The memory card of claim 1 wherein the point-of-sale interface comprises circuitry to produce at least one time-varying magnetic field.

3. The memory card of claim 2 wherein the point-of-sale interface includes smartcard circuitry.

4. The memory card of claim 1 wherein the point-of-sale interface includes circuitry compatible with a hybrid smartcard reader.

5. The memory card of claim 1 wherein the point-of-sale interface includes smartcard circuitry.

6. The memory card of claim 1 further including software to be installed on the mobile phone.

7. An apparatus for performing a financial transaction 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, wherein the means for producing receives power from the memory card slot; and

means for storing the financial transaction data.

8. The apparatus of claim 7 further including software to be installed on the intelligent electronic device.

9. The apparatus of claim 8 wherein the software is configured to run on a mobile phone.

10. The apparatus of claim 7 further comprising nonvolatile memory accessible through the means for communicating through a memory card slot.

11. The apparatus of claim 7 wherein the means for producing at least one time-varying magnetic field includes circuitry compatible with a hybrid smartcard reader.

12. The apparatus of claim 7 wherein the means for producing at least one time-varying magnetic field includes smartcard circuitry.

13. The apparatus of claim 7 wherein the means for communicating through a memory card slot comprises a capacitor to be charged and to power the means for producing at least one time-varying magnetic field.

14. An electronic transaction card comprising:

a memory card slot interface; and

circuitry powered by the memory card slot interface for producing a signal compatible with a card reader.

15. The electronic transaction card of claim 14 further comprising nonvolatile memory accessible via the memory card slot interface.

16. The electronic transaction card of claim 14 wherein the circuitry for producing a signal compatible with a card reader includes circuitry compatible with a hybrid smartcard reader.

17. The electronic transaction card of claim 14 wherein the circuitry for producing a signal compatible with a card reader includes smartcard circuitry.

18. The electronic transaction card of claim 14 further comprising software to be transferred to a device other than the electronic transaction card.

19. The electronic transaction card of claim 14 further comprising a capacitor to be charged by the memory card interface and to supply power to the electronic transaction card.

20. The electronic transaction card of claim 14 further comprising a battery to be charged by the memory card interface and to supply power to the electronic transaction card.
