RFID System
RFID (Radio Frequency Identification) is a contactless auto-ID technology. It uses RF (LF, HF, UHF or microwave) signals to implement a contactless communication between RFID reader and tags so as to automatically identify the targets and obtain data.
A complete RFID system is made up of tags (transponders), RFID reader, and host system. The tags (transponders) play the role of information carriers of RFID systems. Each tag has a unique electronic series code embedded in it.
