Abstract
A system and method system for synchronizing Radio Frequency Identification (RFID) readers includes a plurality of RFID readers disposed within an environment. Each RFID reader includes an infrared emitter and an infrared detector. A master controller also includes a master infrared emitter and is operable to emit a master infrared flash from the master infrared emitter for synchronizing the plurality of RFID readers. Any of the RFID readers, upon detecting an infrared flash with their associated infrared detector, is operable to synchronize their dwell timing with the detected infrared flash and emit their own infrared flash from their associated infrared emitter, so as to propagate infrared flashes to all the RFID readers within the environment.
