Title:
近距離無線通信装置を含む携帯品
Document Type and Number:
Japanese Patent JP6514760
Kind Code:
B2
Abstract:
A portable object includes a near-field communication device. The communication device includes an electronic chip provided with two terminals connected to an electrical circuit including an antenna and a filter. The communication device is provided to receive and transmit at a defined frequency corresponding to the resonance frequency of the electrical circuit. The portable object includes a control element which is able to be displaced between two predefined positions, i.e. an active position in which the communication device is activated and a passive position in which the communication device is deactivated. The electrical circuit includes, furthermore, a bypass branch provided with a mechanical switch which is able to switch between an open state and a closed state in response to a displacement of the control element from one to the other of its predefined positions causing a modification in the resonance frequency of the electrical circuit.
