RFID Reader and Method for Anti-Collision in a Multi-Tag RFID System

摘要

Example embodiments relate to radio frequency identification (RFID) readers and methods for anti-collision in multi-tag RFID systems. One embodiment includes a RFID reader. The RFID reader includes an antenna module configured to scan a plurality of tags. Each of the plurality of tags has a unique identifier (UID) and includes information on an object to which the tag is attached. The RFID reader also includes a control module configured to activate the antenna module to identify the plurality of tags and, in response to a collision event, send a select command with a select condition to identify a specific tag.
