RFID tag reader

摘要: The utility model relates to the technical field of RFID, and in particular an RFID tag reader. reader is characterized that read-write circuit comprises a main control module, carrier regulation signal generation modulation circuit, radio frequency amplification filter impedance matching demodulation receiving parameter feedback detection communication interface circuit; connected with module; ends are output respectively end circuit. According model, self-adaption adjustment carried out before reading writing on tag, thus efficiency accuracy number tags which densely placed can be effectively improved.
