PASSIVE RADIO FREQUENCY IDENTIFICATION TAG, RADIO FREQUENCY READ/WRITE HEAD AND RADIO FREQUENCY IDENTIFICATION SYSTEM

摘要

The present invention discloses a passive RFID tag, an RF read/write head and an RFID system. The RFID system includes: an RF antenna, connected with a chip; a plurality of optical transmitters, connected with the chip; and the chip, configured to control an optical transmitter corresponding to a designated RFID tag in the plurality of optical transmitters to emit light so as to start the designated RFID tag when a read/write operation is carried out on the designated RFID tag in the plurality of RFID tags, and carry out the read/write operation on the designated RFID tag. Through embodiments of the present invention, non-contact-type RFID is realized, and mutual interference of the RFID tags in dense scenes is reduced or avoided.
