Abstract
A radio frequency identification (RFID) tag tracking system is provided for performing an RFID tag tracking method. The RFID tag tracking system includes an RFID tag, at least one RFID reader, and a backend-server. The RFID tag periodically emits tag signals having different original signal strengths, and the original signal strength of each tag signal determines a signal receiving boundary relative to the RFID tag. The RFID reader is used to receive the tag signals, and the tag signal that can be received by the RFID reader receives the tag signals, and determines one or more receivable signals which cab be received by the RFID reader among the tag signals. The backend-server determines a possible position area of the RFID tag relative to the RFID reader according to the signal receiving boundary of the receivable signal.
