A distributed RFID reader activation approach

Radio Frequency Identification (RFID) is a rapidly developing digital identification technology that employs radio to collect identification information from RFID tags. In a typical RFID identification scenario, an RFID reader sends a request to RFID tags, and the RFID tags reply with the information pre-stored in their storages. In recent decades, many applications such as supply chain management, auto-ticking, human and animal tracking, smart hospital, etc. employ more and more RFID readers.
