Abstract: An operation of calibrating the object using a reference reader is performed, the calibration operation including an operation of placing the reference reader at various distances away from the object that correspond to various values of a parameter within the object that is representative of the intensity of the signal received by the object, and, for each distance, an operation of determining an internal phase-shift compensation in the object with respect to a nominal internal phase shift, making it possible to obtain a load modulation amplitude that is higher, in terms of absolute value, than a threshold, and an operation of storing a lookup table of the various values of the parameter and the corresponding internal phase-shift compensations.

Abstract: A contactless device includes an impedance matching and filter circuit connected to an antenna and being on the one hand operable for contactlessly communicating with a second device via the antenna, and on the other hand operable for contactlessly charging a rechargeable power supply of a third device via the antenna. A method of control includes modifying the impedance matching and filter circuit of the contactless device depending on whether the contactless device carries out the contactless communication or carries out the contactless charging.

Abstract: An object is capable of contactless communication with a reader by active charge modulation. The object includes an antenna, an impedance matching circuit, a memory, and a controller connected to the antenna through the impedance matching circuit. The antenna, the an impedance matching circuit and the controller together form a resonant circuit having a resonant frequency. The controller is configured to cause the object to transmit, in the absence of a signal received from a reader, a signal at the resonant frequency, to determine a characteristic obtained from the signal uniquely transmitted by the object, and to perform an adjustment of a phase shift within the object based on the characteristic and an indication stored in the memory, the indication linking values of phase shifts with values of the characteristic.
