Abstract:
The present invention provides a system and method for an improved player tracking in a gaming environment. Certain embodiments include a plurality of radio frequency identification (RFID) readers for detecting a response signal from an RFID tag, an RFID tag generating a response signal including identification data in response to an interrogation signal transmitted by one of the plurality of RFID readers, and a location manager controlling transmission by the plurality of RFID readers according to at least one collision-avoidance scheme. The collision-avoidance scheme may include one or more of the following schemes: localized RFID reader managers coordinating electrical operation of the plurality of RFID readers, an active RFID reader transmitting the interrogation signal and a plurality of passive RFID readers listening for the response signal, an RFID reader multiplexed through a plurality of antennas, TDMA, CDMA, and/or quasi-random synchronization for the RFID readers, for example.
