METHOD AND A DEVICE FOR IDENTIFYING THE POSITION OF A TRANSPONDER
First Claim
1. A method of identifying a position of a terminal relative to a transponder fitted with a circuit presenting a load impedance, said terminal being suitable for receiving signals from the transponder, the method comprising:
- a step of the terminal receiving a first signal relating to the load impedance of the transponder;
a step of obtaining a second signal from the first signal;
a step of determining a position indication about the position of the terminal relative to the transponder and based on analyzing the second signal; and
a step of delivering a third signal as a function of the position indication as determined.

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.
