SYSTEM FOR SIMULTANEOUS IDENTIFICATION OF MASSIVE RFID TAGS FOR HF BAND

摘要

A tag of an apparatus to simultaneously identify massive tags according to the present invention may include an analog circuit unit to communicate with a reader through an analog signal and to receive energy via magnetic coupling with the reader. Furthermore, the tag may include a digital circuit unit to be supplied with power from the analog circuit unit. The digital circuit unit may support a sleep mode for the tag to stand by in a low power state after transmitting an identifier (ID) to the reader and a wait mode to control random access to the reader. [Reference numerals] (110) Reader; (130) Recognition area; (140,AA,BB,CC,DD,EE,FF,GG,HH,II) Tag
