Abstract

Method for broadcasting a magnetic stripe data packet from an electronic card by measuring a swipe speed of the electronic card past a magnetic reader head during a swipe of the electronic card past the magnetic reader head and then adjusting a broadcast signal containing the magnetic stripe data packet according to the measured swipe speed so that the magnetic stripe data packet in the broadcast signal is read by the magnetic reader head during said swipe. The swipe speed is measured by either an active speed sensor or a passive pressure/force speed sensor such as a quantum tunneling composite.

Claims

1. A method comprising broadcasting a transaction specific magnetic stripe data packet from an electronic card by measuring a swipe speed of the electronic card past a magnetic reader head during a swipe of the electronic card past the magnetic reader head and then adjusting a broadcast signal containing the transaction specific magnetic stripe data packet according to the measured swipe speed so that the transaction specific magnetic stripe data packet in the broadcast signal is read by the magnetic reader head during said swipe, wherein the swipe speed is measured by a passive speed sensor comprised of a quantum tunnelling composite.

2. The method of claim 1 wherein the transaction specific magnetic stripe data packet is comprised of a track 2 data packet and a track 1 data packet.

3. The method of claim 2 wherein cross talk in the magnetic reader head responsible for reading track 1 data is prevented by use of a piece of magnetic tape located on the electronic card.

4. The method of claim 3 wherein the passive speed sensor is comprised of an outer passive sensor and an inner passive sensor and both the outer passive sensor and the inner passive sensor are placed across a track 1 location and a track 2 location of the electronic card.

5. The method of claim 4 wherein the broadcast signal is not broadcast until the magnetic reader head has traveled beyond a broadcast terminal of a broadcaster of the electronic card.

6. The method of claim 5 wherein the broadcast signal is adjusted by varying bit rate used to broadcast said broadcast signal.

7. The method of claim 1 wherein the passive speed sensor is comprised of an outer passive sensor placed across a track 1 location and a track 2 location of the electronic card and an inner passive sensor placed along the track 1 location of the electronic card.

8. The method of claim 1 wherein the passive speed sensor is comprised of a passive sensor placed along a track 1 location of the electronic card.

9. The method of claim 1 wherein the passive speed sensor is comprised of a passive sensor placed across a track 1 location and a track 2 location of the electronic card.

10. A method, comprising:

activating an electronic card from an off state to a sleep mode;

changing the electronic card from the sleep mode to an active mode after a wake up sensor is activated during a swipe of the electronic card past a magnetic reader head;

measuring a swipe speed of the electronic card past the magnetic reader head during the swipe;

using the swipe speed to adjust a broadcast signal containing a transaction specific magnetic stripe data packet; and

broadcasting the broadcast signal during the swipe so that the magnetic reader head reads the transaction specific magnetic stripe data packet;

wherein the wake up sensor is comprised of a quantum tunnelling composite.

11. The method of claim 10 wherein the swipe speed is measured by an active sensor having an outer detection point and an inner detection point.

12. The method of claim 11 wherein a false swipe detection is prevented by measuring movement past the outer detection point and the inner detection point.

13. The method of claim 12 wherein a broadcaster in the electronic card is activated during the active mode.

14. The method of claim 13 wherein the broadcast signal is adjusted by varying a bit rate used by the broadcaster to broadcast said broadcast signal.

15. The method of claim 14 wherein the broadcaster is comprised of a track 2 broadcaster that broadcasts a track 2 data packet and a track 1 broadcaster that broadcasts a track 1 data packet.

16. The method of claim 15 wherein a cross talk blocker is used to prevent the magnetic reader head from reading a particular track data packet in a reading area of the magnetic reader head that is not meant to read the particular track data packet.
