First Claim
1. A system to determine the identity of gaming chips bet in a casino, the system comprising:
- a plurality of gaming chips each comprising an RFID device which comprises unique RFID identification;
a casino gaming table comprising a plurality of player betting positions for betting one or more of the plurality of chips;
two or more antennas associated with each of one or more of the plurality of betting positions, the two or more antennas associated with each of the one or more betting positions (a) transmitting interrogation signals in an antenna excitation sequence to the RFID device or devices of the one or more chips of the plurality of chips placed in the associated betting position and (b) receiving response signals from the respective RFID device or devices of the respective chip or chips in the associated betting position; and
at least one processor coupled to the antennas associated with each of the one or more betting positions, the at least one processor being programmed togenerate respective excitation sequences,receive respective response signals of a respective chip or chips, andprocess the respective response signals and determine the identity of a respective chip or chips which provide response signals.
