Abstract:
The invention concerns a Near Field Communication method comprising a step (1) of generating, by an antenna of a transmitter, a magnetic field (H), a step (2) of receiving, by an antenna of a tag, power from the generated magnetic field (H), then causing a drop in the generated magnetic field (H), wherein the method further comprises a step (3) of estimating the drop by sensing a voltage swing across said transmitter antenna.
