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.

17. 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. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29)

30. 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. - View Dependent Claims (31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43)

54. 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. - View Dependent Claims (55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67)

68. 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. - View Dependent Claims (69, 70)
