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.
