Abstract

An integrated RFID and RFID read-write terminal equipment comprises RFID module, RFID read and write equipment and circuit connected to the said RFID read and write equipment terminal equipment circuit, and also the shared antenna connected with the circuit. It solves the issue of multi RFID device independent antenna brought about design and manufacturing issue, ensures the normal running of them under shared antenna, designing the best antenna in consideration of the harmonic circuit principle through shared antenna RFID input capacitor to ensure the good performance of the RFID identification.

Description

technical field [0001] The invention relates to the field of automatic identification, in particular to a terminal device integrating RFID (Radio Frequency Automatic Identification) and RFID reader-writer functions. Background technique [0002] After years of development, radio frequency automatic identification (RFID) technology has penetrated into every corner of modern life and is widely used in many fields such as logistics management, identification, article anti-counterfeiting, public transportation, and small electronic payment. Among them, the non-contact traffic card commonly used by people is a typical RFID application. In addition to the form of cards, RFID can also have various packaging forms such as paper labels and chips. The common features of these RFIDs are all composed of an antenna and chip circuit, and then attached to carriers of different shapes and materials. Correspondingly, the RFID reader is also composed of an antenna and a circuit. [0003] F...
