Method for broadcasting a magnetic stripe data packet from an electronic smart card

摘要

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.
