Abstract
A system and method for managing a population of RFID tags. In various aspects, an RFID reader implements one or more RFID protocols to execute a read cycle that defines a series of actions for the RFID reader to perform. The read cycle may begin by the RFID reader broadcasting a query to deselected RFID tags to generate a list of deselected tag identifiers. The read cycle then causes the RFID reader to broadcast a query to selected RFID tags to track selected RFID tags. Finally, the read cycle causes the RFID reader to broadcast a selection command that includes the list of deselected tag identifiers.
