How does Rfid Work?

RFID stands for Radio-Frequency IDentification, and an RFID system has three parts, a scanning antenna, a transceiver with decoder, and a transponder, which is the RFID tag. The antenna puts out a radio frequency in a small area, and when an RFID tag passes through, it detects the antenna, and sends it’s information to the transceiver. Look here for more information:
