A small card reader has a read head with a slot and positioned in a housing. The read head is configured to be coupled to a mobile device. The read head reads data on the magnetic stripe from a card that is slid in the slot and produces an output jack signal indicative of data stored on the magnetic stripe. An output jack is adapted to be inserted in a port of the mobile device and deliver the output jack signal to the mobile device. The read head positioned to accommodate rocking of a card while being swept in the slot while producing a successful read of the magnetic stripe of the card. The rocking is in an amount of 1 to 10 degrees of rotation of a bottom surface of the card away from a bottom surface of the slot.

1. A card reader configured to be coupled to a mobile device, comprising: a housing;a card slot positioned within the housing, the card slot including a flat bottom surface, and further including a read head, wherein the read head is configured for reading data stored on a magnetic stripe of a card
1. A card reader configured to be coupled to a mobile device, comprising: a housing;a card slot positioned within the housing, the card slot including a flat bottom surface, and further including a read head, wherein the read head is configured for reading data stored on a magnetic stripe of a card that is inserted into the card slot, and wherein the reading data produces a signal indicative of the data stored on the magnetic stripe;an output jack adapted to be inserted in a port of the mobile device and deliver the signal indicative of the data to the mobile device; andwherein a magnetic read head element of the read head is configured to read a track of the magnetic stripe of the card, wherein the magnetic read head element is vertically positioned within the card slot to be vertically offset from a center of the track of the magnetic stripe of the card when a first horizontal length of a bottom surface of the card is in contact with a second horizontal length of the flat bottom surface of the card slot, whereby the read head is able to accommodate rocking of the card that is inserted into the card slot in an amount of 1 to 10 degrees of rotation from the bottom surface of the card relative to the flat bottom surface of the card slot and still read the track of the magnetic stripe of the card. 2. The card reader of claim 1, wherein the rocking is 2 to 10 degrees of rotation. 3. The card reader of claim 1, wherein the rocking is 3 to 10 degrees of rotation. 4. The card reader of claim 1, wherein the rocking is 4 to 10 degrees of rotation. 5. The card reader of claim 1, wherein the rocking is 5 to 10 degrees of rotation. 6. The card reader of claim 1, wherein the rotation is in the direction of a plane of the card. 7. The card reader of claim 1, wherein the signal delivered by the output jack is an encrypted output jack signal. 8. The card reader of claim 1, wherein the signal delivered by the output jack is an encrypted and signed output jack signal. 9. The card reader of claim 1, wherein the read head has a side where the output jack extends with a width of no more than 5 mm. 10. The card reader of claim 1, wherein the card slot is configured to provide for directionality of card swipe direction. 11. The card reader of claim 10, wherein the card slot has a wider entrance track at one end to receive a card. 12. The card reader of claim 10, wherein directionality is provided with indicia on the housing. 13. The card reader of claim 1, further comprising: device electronics that include an analog to digital front end, and a microcontroller, the analog to digital front end coupled to a processing element in the microcontroller, the analog to digital front end receiving a raw magnetic head signal and converting the raw magnetic head signal into a processed digital signal that the microcontroller can interpret, the microcontroller producing an output jack signal. 14. The card reader of claim 13, wherein the analog to digital front end includes, an amplifier/filter, differentiator and a comparator. 15. The card reader of claim 14, wherein the analog to digital front end further includes wake-up electronics. 16. The card reader of claim 15, wherein the wake-up electronics is a wake-up circuit. 17. The card reader of claim 13, wherein the output jack signal is a synchronous Manchester encoded stream. 18. The card reader of claim 13, wherein the output jack signal is an asynchronized stream. 19. The card reader of claim 13, wherein the output jack signal is at a frequency that the output jack signal appears to look AC to a microphone input of the mobile device. 20. The card reader of claim 13, wherein a frequency of the output jack signal is 2 KHz to 48 kHz. 21. The card reader of claim 13, wherein a frequency of the output jack signal is 2.4 kHz. 22. The card reader of claim 13, wherein the microcontroller has a nonvolatile memory with a size of 2-8 kbytes, and RAM with a size 128-512 bytes. 23. The card reader of claim 1, wherein the read head is horizontally positioned within the card slot to be closer to one end of the card slot. 24. The card reader of claim 1, further comprising: an asymmetric spring. 25. The card reader of claim 1, wherein the read head is offset 0.05 inches in a direction x. 26. The card reader of claim 1, wherein the read head is offset 0.040 inches in a y direction. 27. The card reader of claim 1, wherein the housing is at most half the length of the card.
