Abstract
A method of power recovery by an electromagnetic transponder in the field of a terminal, wherein: a ratio of the current coupling factor of the transponder with the terminal to an optimum coupling position with a resistive load value is evaluated; and a detuning of the oscillating circuit is caused if the ratio is greater than a first threshold greater than or equal to one.
