Abstract
A system and method for a gaming chip identification system are disclosed. Briefly described, one embodiment comprises a plurality of gaming chips, each gaming chip operable to emit a respective unique electromagnetic signature in response to incident non-optical electromagnetic radiation, a computer-readable medium that stores information indicative of the electromagnetic signatures of at least a number of the plurality of gaming chips, and a processor-based system configured to verify that the electromagnetic signature from an interrogated gaming chip in an interrogation zone is a member of the plurality of gaming chips.
Claims70
A system to facilitate wagering, the system comprising:
- at least one transmitter operable to emit non-optical electromagnetic energy via at least one antenna;
- at least one receiver operable to receive a resonant response from gaming chips within a range of the emitted non-optical electromagnetic energy via at least one antenna;
- a computer-readable medium that stores information indicative of at least one resonant response of a valid set of gaming chips;
- and
- at least one processor programmed to determine whether a gaming chip is from the valid set based at least in part on a received resonant response.
A method of uniquely identifying a plurality of gaming chips, comprising:
- emitting non-optical electromagnetic energy via at least one antenna;
- receiving a number of resonant responses from a number of gaming chips without a memory, the gaming chips within a range of the emitted non-optical electromagnetic energy via at least one antenna;
- and
- determining at least one respective characteristic of each of a number of the gaming chips based on the received resonant responses.
A set of gaming chips, comprising;
- a first plurality of gaming chips each bearing indicia of a first denomination, each of the first plurality of gaming chips having a first resonant marker that resonates in a first resonant frequency band in response to absorbing electromagnetic energy characterized by a selected frequency, and that emits non-optical electromagnetic energy with a first electromagnetic signature;
- and
- a second plurality of gaming chips each bearing indicia of a second denomination, different from the first denomination, and each of the second plurality of gaming chips having a second resonant marker that resonates in a second resonant frequency band in response to absorbing the electromagnetic energy characterized by the selected frequency, and that emits non-optical electromagnetic energy with a second electromagnetic signature, wherein the first unique electromagnetic signature and the second unique electromagnetic signature are discernibly different.
A system to form valid sets of gaming chips, comprising:
- at least one transmitter operable to emit non-optical electromagnetic energy via at least one antenna;
- at least one receiver operable to receive a resonant response from any resonant markers within a range of the emitted non-optical electromagnetic energy via at least one antenna;
- a computer-readable medium operable to store information indicative of resonant responses from a plurality of resonant markers;
- and
- at least one processor programmed to determine whether received resonant responses from the resonant markers are discernibly distinct from the resonant responses of resonant markers for which information indicative of the resonant response has previously stored in the computer-readable medium.
A method of forming valid sets of gaming chips, the method comprising:
- emitting non-optical electromagnetic energy via at least one antenna;
- receiving a returning non-optical electromagnetic resonant response from a resonant marker in response to the emitted non-optical electromagnetic energy;
- and
- determining whether the received resonant response is discernibly distinct from all resonant responses from respective ones of a number of resonant markers for which information indicative of the respective resonant responses has previously been stored in a computer-readable medium.
A computer-readable medium storing instructions that cause a processor to form valid sets of gaming chips, by:
- determining whether a received resonant response is discernibly distinct from all resonant responses from respective ones of a number of resonant markers for which information indicative of the respective resonant responses has previously been stored in a computer-readable medium;
- and
- storing information indicative of the received resonant response in the computer-readable medium if the received resonant response is discernibly distinct from the resonant responses for which information indicative of the resonant response has previously been stored in the computer-readable medium.
