Abstract

A method and apparatus for tracking and determining a location of a gaming machine or other item within a casino or hotel is disclosed. In one embodiment the method and apparatus utilizes a transmitter or emitter to provide a tracking signal that may be tracked by one or more receivers or detectors. It is contemplated that the transmitter or emitter connect to a gaming machine. As the gaming machine is relocated within the casino its location is monitored. The one or more receivers may communicate with a host computer or other data processing system to generate location data regarding the gaming machine in relation to other aspects of the casino. Based on the location information generated by the location monitoring and tracking system, other aspects of machine operation may be controlled and additional features dependant on the machine location information may be enabled.

generating a graphical map of the casino floor;

indicating the location of the gaming machine on the graphical map of the casino floor; and

configuring operational parameters of the gaming machine based upon the indicated location of the gaming machine on the graphical map of the casino floor.

8. The method of claim 7, further including transmitting one or more signals from the tracking device located on the gaming machine.

9. The method of claim 7, wherein processing the one or more signals from the tracking device comprises processing signals received from at least three different receivers.

10. The method of claim 7, wherein the signal comprises an infrared type signal.

11. The method of claim 7, wherein the tracking device comprises a radio frequency identification tag.

12. The method of claim 7, further including generating a representation of the gaming machine on a graphical representation of the casino floor.

27. A method as recited in claim 7 further comprising:

receiving location operational parameters at a gaming machine control module, the location operational parameters defining rules that govern the operational parameters of the gaming machine based upon the location of the gaming machine on the casino floor.

28. A method as recited in claim 27 wherein the location operational parameters define rules pertaining to at least one of enabling and disabling gaming machine operation, game selection, and payout rates.

29. A method as recited in claim 27 further comprising:
