Payment cards and devices with enhanced magnetic emulators
A payment card (e.g., credit and/or debit card) or other device (e.g., mobile telephone) is provided with a magnetic emulator operable to communicate data to a magnetic stripe read-head. Such a magnetic emulator may comprise non-magnetostrictive material such that the magnetic emulator may be fabricated in a wide variety of fabrication processes. Additionally, magnets may be added to amplify the signal of a magnetic emulator. In doing so, a magnetic emulator may provide a large amount of signal while consuming a reduced amount of electrical energy when compared to a magnetic emulator that does not include the presence of one or more magnets.
1. A card comprising:
a plurality of magnetic emulators, wherein each one of said plurality of magnetic emulators comprises:
a coil having an interior and an exterior for producing an electromagnetic signal;
a material placed within said interior of said coil for increasing the amount of said electromagnetic signal located about said exterior of said coil; and
a magnet placed within said interior of said coil for providing a bias signal.
2. The card of claim 1 further comprising a display.
3. The card of claim 1 further comprising a non bi-stable display.
4. The card of claim 1 further comprising a bi-stable display and a non bi-stable display.
5. The card of claim 1 , wherein said plurality of magnetic emulators were fabricated on printed circuit board and a property of said magnet was tested after manufacturing of said printed circuit board.
6. The card of claim 1 , further comprising a battery.
7. The card of claim 1 , further comprising a processor.
8. The card of claim 1 , further comprising:
a battery; and
a processor.
9. The card of claim 1 , wherein said plurality of magnetic emulators were fabricated on a printed circuit board.
10. The card of claim 1 , wherein said plurality of magnetic emulators were fabricated on a flexible printed circuit board.
11. The card of claim 1 , further comprising a read-head detector.
12. The card of claim 1 , further comprising an RFID.
13. The card of claim 1 , further comprising a button.
14. The card of claim 1 , further comprising a plurality of buttons.
15. The card of claim 1 , wherein said card is a payment card.
16. The card of claim 1 , further comprising a read-head detector.
17. The card of claim 1 , further comprising a plurality of read-head detectors.
18. The card of claim 1 , further comprising an IC chip.
19. The card of claim 1 , wherein said material is substantially non-magnetostrictive.
20. The card of claim 1 , wherein said plurality of magnetic emulators is two magnetic emulators.
21. The card of claim 1 , further comprising a payment card number.
