Abstract
A contactless payment device and method transmits a sequence of magnetic-field pulses directly to two or three magnetic-stripe read heads of a point-of-sale terminal. The baud rate at which the data is transmitted is modulated so that track data for one read head channel will be ignored by another read head channel, based on the change to the baud rate and/or the rate of change in the baud rate to improve acceptance of the transmitted pulses received by the read heads of the point-of-sale terminal.
