ABSTRACT:
A system for remote information exchange between a portable object and a station and in which in order to minimize an undesirable profitless cluttering in the radio frequency environment of the system, the phase variation between the first and second alternating voltages (VEX and VEY), which is induced by the switchings of the electronic circuit of the portable object as a function of information to be transmitted to the station, enables the station-processing means (SPM) to deduce the information therefrom, and the elements of the electronic circuit and of the station are chosen and configured so that the phase variation induce by the inductive coupling is greater than a predetermined threshold.
