Cards and devices with multifunction magnetic emulators and methods for using same
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).
1. An apparatus comprising:
a structure for receiving manual input;
a dynamic magnetic stripe communication device; and
a processor for controlling the dynamic magnetic stripe communication device,
wherein the dynamic magnetic stripe communication device is operable to electrically couple to a payment terminal when the dynamic magnetic stripe communication device is located outside and within proximity of the payment terminal and to serially communicate first magnetic stripe track data and second magnetic stripe track data while electrically coupled to the payment terminal.
2. The apparatus of claim 1 , wherein the apparatus is thicker than a payment card.
3. The apparatus of claim 1 , wherein the apparatus is a wireless communication device.
4. The apparatus of claim 1 , wherein the apparatus is a portable telephonic device.
5. The apparatus of claim 1 , wherein the apparatus is a portable media player.
6. The apparatus of claim 1 , further comprising a display operable to display a virtual payment card.
7. The apparatus of claim 1 , further comprising a touch-sensitive display operable to display a virtual payment card.
8. The apparatus of claim 1 , wherein the processor is operable to determine the presence of a read-head of a magnetic stripe reader based on received information.
9. The apparatus of claim 1 , wherein the processor is operable to:
determine presence of a read-head of a magnetic stripe reader based on received information; and
drive the dynamic magnetic stripe communication device to couple with the magnetic stripe reader.
10. The apparatus of claim 1 , wherein the processor is operable to determine the presence of an RFID receiver based on received information.
11. The apparatus of claim 1 , wherein the processor is operable to:
determine presence of a read-head of an RFID receiver based on received information; and
drive the dynamic magnetic stripe communication device to couple with the RFID receiver.
12. The apparatus of claim 1 , wherein the serial communication occurs as a result of receiving the manual input.
13. The apparatus of claim 1 , wherein the first magnetic stripe track data and the second magnetic stripe track data are the same track data.
14. The apparatus of claim 13 , wherein the first magnetic stripe track data is sent in a forward direction, and the second magnetic stripe track data is sent in a reverse direction.
15. The apparatus of claim 12 , wherein the first magnetic stripe track data and the second magnetic stripe track data are the same track data, and wherein the first magnetic stripe track data is sent in a forward direction, and the second magnetic stripe track data is sent in a reverse direction.
16. The apparatus of claim 13 , wherein the first magnetic stripe track data is sent in a forward direction, and the second magnetic stripe track data is sent in a forward direction.
17. The apparatus of claim 1 , wherein the first magnetic stripe track data and the second magnetic stripe track data are different track data, and wherein the first magnetic stripe track data is sent in a forward direction, and the second magnetic stripe track data is sent in a reverse direction.
18. The apparatus of claim 1 , wherein the first magnetic stripe track data and the second magnetic stripe track data are different track data, and wherein the first magnetic stripe track data is sent in a forward direction, and the second magnetic stripe track data is sent in a forward direction.
19. The apparatus of claim 1 , wherein the dynamic magnetic stripe communication device further serially communicates third magnetic stripe track data.
20. The apparatus of claim 1 , wherein the first magnetic stripe track data comprises a first set of leading zeros and the second magnetic stripe track data comprises a second set of leading zeros that is different than the first set of leading zeros.
21. The apparatus of claim 1 , wherein at least one of the first magnetic stripe track data and the second magnetic stripe track data comprises dynamic codes.
22. The apparatus of claim 1 , wherein temporal pauses occur between the serial communications of the first magnetic stripe track data and the second magnetic stripe track data.
