Credit, security, debit cards and the like with buttons
A card is provided, such as a credit card or security card, that may transmit information to a magnetic stripe reader via a magnetic emulator. The emulator may transmit the information in order to reduce the amount of circuitry needed to emulate a particular block of information. Additionally, for example, one or more buttons may be included on the card. Buttons may be includes, for example, to provide a control interface to navigate through various options of the card. Additionally, coding schemes may be selected via buttons. Furthermore, a card may be locked until a private number is entered into a card or a number may only be generated (e.g., displayed and/or emulated) once a particular private number is entered into a card.
1. A card comprising:
a card reader communications device operable to communicate a data block of magnetic stripe data;
a first button, wherein a first encryption algorithm for said data block is selected based on a first signal from said first button; and
a second button, wherein a second encryption algorithm for said data block is selected based on a second signal from said second button and said first encryption algorithm is different from said second encryption algorithm.
2. The card of claim 1 , further comprising a third button.
3. The card of claim 1 , wherein said card reader communications device is a dynamic magnetic stripe communications device.
4. The card of claim 1 , further comprising a first surface, wherein a display and said second button are located on said first surface.
5. The card of claim 1 , further comprising:
a third button; and
a display.
6. The card of claim 1 , further comprising a processor.
7. The card of claim 1 , further comprising:
a processor; and
an IC chip.
8. The card of claim 1 , further comprising:
a processor; and
an RFID.
9. The card of claim 1 , further comprising memory.
10. The card of claim 1 , further comprising a non bistable display.
