Abstract

A payment card (e.g., credit and/or debit card) is provided with a magnetic emulator operable of communicating information to a magnetic stripe reader. Information used in validating a financial transaction is encrypted based on time such that a validating server requires receipt of the appropriate encrypted information for a period of time to validate a transaction for that period of time. Such dynamic information may be communicated using such an emulator such that a card may be swiped through a magnetic stripe reader—yet communicate different information based on time. An emulator may receive information as well as communicate information to a variety of receivers (e.g., an RFID receiver).

First claim

1 - 5 . (canceled)

17 . A device comprising:
a magnetic emulator operable to electrically couple to and communicate data to a read-head of a magnetic stripe reader; and a processor for controlling the magnetic emulator; wherein the magnetic emulator is operable to electrically couple to and communicate the data to the read-head when the device is located outside and within proximity of the magnetic stripe reader.

18 . The device of claim 17 , wherein the device is thicker than a credit card.

19 . The device of claim 17 , wherein the device is a wireless communication device.

20 . The device of claim 17 , wherein the magnetic emulator is operable to electrically couple to and communicate the data to the read-head when the device is located at least a quarter of an inch away from the read-head.

21 . The device of claim 17 , wherein the magnetic emulator is operable to electrically couple to and communicate the data to the read-head when the read-head is further from the device than the thickness of a housing of the magnetic stripe reader.

22 . The device of claim 17 , wherein the device is a portable telephonic device.

23 . The device of claim 17 , wherein the device is a portable media player.

24 . The device of claim 17 , further comprising a display operable to display a virtual card.

25 . The device of claim 17 , further comprising a touch-sensitive display operable to display a virtual card.

26 . The device of claim 17 , wherein the magnetic emulator is operable to communicate the data using RFID protocol.

27 . The device of claim 17 , wherein the magnetic emulator is operable to communicate the data using frequency/double frequency (F2F) encoding.
