Abstract
A terminal is provided, which has a near-field communication module suitable for receiving signals from a transponder fitted with a circuit presenting a load impedance. The terminal includes a receiver suitable for receiving a first signal relating to the load impedance of the transponder (T3). The terminal obtains a second signal from the first signal and determines a position indication of the terminal relative to the transponder and based on analysis of the second signal. The terminal delivers a third signal that is a function of the determined position indication.
