- the directivity directions of the respective antennas of the interrogator and the transbonder are configured to face each other, the communication between the interrogator and the transbonder is performed accurately.
- the radio wave transmitted from the interrogator and the radio wave transmitted from the transbonder are centered on the key. Since it passes through the vicinity, the quality of wireless communication can be ensured.
- the key and the reader are detachable by magnetic attraction. Further, according to the present invention, the influence of the magnetic field near the center of the ring due to the magnet can be reduced, and the reliability of wireless communication between the interrogator and the transbonder can be improved.
- the position of the key and the reader that is, the position of the interrogator and the transbonder can be set to the optimal positional relationship, and the reliability of wireless communication between the interrogator and the transbonder can be improved. Can be. In addition, it is possible to prevent a magnetic card or the like from contacting a magnet.
- the security function of the electronic device can be improved. Further, according to the present invention, it is possible to easily develop an electronic device having a conventional configuration, thereby improving development efficiency.
