A transponder comprising a resonant circuit, comprising an antenna and a capacitor, and at least one memory connected to the resonant circuit via an intermediate circuit, characterized in that the intermediate circuit comprises at least one contact zone for receiving a portion of human body, so that the positioning of a portion of human body on a contact zone modifies the intermediate circuit, capable of switching from a first state in which it does not allow the memory to be read and/or written to a second state in which it allows the memory to be read and/or written when the resonant circuit of the transponder is contactlessly powered by a reader. |
