Abstract
A method for managing the power in an electromagnetic transponder in the field of a terminal, including the steps of: evaluating the power consumption of the transponder circuits; and if this power consumption is below a threshold, evaluating the current coupling factor between the transponder and the terminal and, according to the current coupling: causing an increase of the transponder power consumption or causing a detuning of an oscillating circuit of the transponder.
