Abstract:
Systems and methods for tracking RFID gaming chips at a gaming table are disclosed. Gaming chips include an outer body with center and rim portions, and a plurality of RFID tags contained within the outer body. Signals from gaming chip RFID tags can be encrypted only for readers having an appropriate private key, and can be subject to a variable time delay unique to each RFID tag. Separate RFID tags within one gaming chip can be identical for security purposes, and to increase “visibility” to associated RFID readers at the gaming table. Security breach components within RFID tags can reduce or prevent unauthorized writing or tampering attempts to an RFID gaming chip. Further system components include a gaming table and a plurality of RFID reading devices distributed thereabout, including transponders and antennae. Such RFID reading devices are disposed beneath an upper surface of the gaming table in a grid-like fashion.
