FEEDBACK SYSTEM AND METHOD FOR READING OF RFID TAGS

摘要

An RFID reader (2) sends an interrogation signal (5) to a series of RFID tags (6, 6', 6''), which respond (7) with their ID. The RFID reader checks a database (11) for the scanned ID, and adds the ID if it is not found. The RFID reader also performs an error detection routine to determine whether the ID is valid, and provides feedback using an indicator (12, 14) to the user when valid tags are read.
