ABSTRACT:
A method for controlling an electromagnetic field generation terminal using a signal for exciting an oscillating circuit, provided with circuitry for regulating the signal phase in the oscillating circuit, including comparing current values of variables linked to the current in the oscillating circuit and to the voltage thereacross with predetermined values, to detect the presence of a transponder in the electromagnetic field.
