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. A system comprising:
a magnetic emulator, wherein said magnetic emulator is operable to electrically couple, and communicate data to, a read-head located on a magnetic stripe reader; and
a magnetic shielding statically located about said magnetic emulator,
wherein said read-head is inoperable to receive data from said magnetic emulator when said magnetic shielding is between said magnetic emulator and said read-head.
2. The system of claim 1 , further comprising:
a source of energy; and
a regulator for regulating said source of energy, wherein said regulated energy is utilized by said magnetic emulator.
3. The system of claim 1 , wherein said communicated data includes a dynamic payment number and a dynamic code.
4. The card of claim 1 , further comprising a processor.
5. The card of claim 1 , further comprising a plurality of flexible layers of circuit board.
6. The card of claim 1 , further comprising a flexible layer of circuit board.
7. The card of claim 1 , further comprising a second magnetic emulator.
8. The card of claim 1 , further comprising:
a processor; and
a button.
9. The card of claim 1 , wherein said magnetic emulator is operable to receive data from an encoding head of said magnetic stripe reader.
10. The card of claim 1 , further comprising a button.
11. The card of claim 1 , further comprising a magnetic stripe encoding receiver operable to receive data from an encoding head of said magnetic stripe reader.
12. The card of claim 1 , further comprising a battery.
13. The card of claim 1 , further comprising a read-head detector for detecting said read-head.
14. The card of claim 1 , further comprising an RFID field detector.
15. The card of claim 1 , further comprising:
a read-head detector; and
an RFID field detector.
16. The card of claim 1 , further comprising:
a battery; and
a button.
17. The card of claim 1 , wherein said magnetic emulator includes a coil.
18. The card of claim 1 , further comprising:
a battery; and
a processor.
19. The card of claim 1 , further comprising:
a second magnetic shielding located about said magnetic emulator.
