摘要：
A method for configuring a terminal capable of emitting a radio-frequency field for a transponder including, in the presence of a transponder within the range of the terminal, at least one step of adaptation of the series resistance of an oscillating circuit of the terminal, according to an off-load value, which depends on an operation of the terminal while no transponder is in its field.
