Wireless data transmission method on a data carrier

Abstract

A method is described for the wireless transmission of data to a data carrier, in particular a chip or IC card, by placing it in a radio-frequency field. To perform an amplitude sample, the field is turned on and off, the information being in the number of periods sent between two transmission pauses. The semiconductor circuit accommodated in the data carrier receives its clock from the received high-frequency field or from an oscillator assigned to the semiconductor circuit, this clock resting during a transmission pause.
