Systems and methods for audio connectors for powered cards and devices
Audio connectors are provided within a card. The audio connectors may be provided having a height that is compatible with a card (e.g., less than 1 mm or less than 0.5 mm). Communications to and from the card may be provided using the audio connectors within the card.
1. A card comprising:
an audio connector and said card having three orthogonal dimensions, wherein said audio connector is smaller than said card in each of said three orthogonal dimensions;
a processor; and
a detector operable to detect a position of said audio connector and to communicate said detection to said processor.
2. The card of claim 1 , wherein said position is an extended position.
3. The card of claim 1 , wherein said detection wakes said processor from a sleep state.
4. The card of claim 1 , wherein said position is a retracted position.
5. The device of claim 1 , wherein said detection places said processor into a sleep state.
6. The card of claim 1 , wherein a width of said audio connector is substantially equal to a diameter of an audio port.
7. The card of claim 1 , wherein said orthogonal dimensions of said audio connector include a height and a width,
said width of said audio connector is substantially equal to a diameter of an audio port, and
said height is less than said diameter of said audio port.
8. The card of claim 1 , wherein said orthogonal dimensions of said audio connector include a height, and
said height is about 10 thousandths of an inch to about 20 thousandths of an inch.
9. The card of claim 1 , further comprising:
an RFID; and
an IC chip.
10. A system comprising:
a device; and
a card having a first height, said card including, an audio connector having a second height less than said first height;
a processor; and
a detector operable to communicate a coupling between said audio connector and said device to said processor,
wherein said second height is less than about 33 thousandths of an inch.
11. The system of claim 10 , wherein data is communicated from said card to said device via said audio connector based on said coupling.
12. The system of claim 10 , wherein said card further includes a button.
13. The system of claim 10 , wherein said card further includes a button, wherein data is communicated from said card to said device via said audio connector based on signals from said button.
14. The system of claim 10 , wherein a width of said audio connector is substantially equal to a diameter of an audio port.
15. The system of claim 10 , wherein a width of said audio connector is substantially equal to a diameter of an audio port, and
said second height is less than said diameter of said audio port.
16. The system of claim 10 , wherein said second height is about 10 thousandths of an inch to about 20 thousandths of an inch.
17. The system of claim 10 , wherein said card includes an RFID and an IC chip.
18. A card comprising:
a button;
an audio connector operable to communicate magnetic stripe track data to a computing device based on signals from said button, wherein said magnetic stripe track data is not communicated as audio data; and
a dynamic magnetic stripe communications device operable to communicate magnetic stripe track data to a read head of a magnetic stripe reader.
