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 a speed sensor such as a capacitive sensor having an outer detection point and an inner detection point. The electronic card can contain a false swipe detection means so that the capacitive sensor changes from a sleep mode to an active mode after a wake up sensor (such as a trip switch preferably having two or more conducting pads raised up from a printed circuit board by at least one spacer) is activated during the swipe and the swipe speed is measured by the capacitive sensor while it is in the active mode before the broadcast signal is broadcast during the swipe.
