RF MODULE AND RF SYSTEM
Document Type and Number:
WIPO Patent Application WO/2016/136565
Kind Code:
A1
Abstract:
According to the present invention, an RF system (100) comprises an RFID card (10) and a read-write device (50). The RFID card (10) comprises a substrate (11), an RFIC element (16), an antenna coil (40) and a deformation sensor (35). The read-write device (50) and the RFID card (10) transmit and receive predetermined information between the antenna coil (40) of the RFID card (10) and the antenna coil of the read-write device (50) via a magnetic field. The RFIC element (16) transmits a first signal via the antenna coil (40) when the deformation sensor (35) does not detect bending deformation of the substrate (11) and transmits a second signal via the antenna coil (40) when the deformation sensor (35) detects bending deformation of the substrate (11).
