1. 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 memoryless gaming chips which do not store identification information within a range of the emitted non-optical electromagnetic energy via the at least one antenna;
wherein each memoryless gaming chip includes a respective resonant marker configured to emit a respective unique resonant response in response to incident non-optical electromagnetic radiation; and
,the resonant markers of each of a first plurality of gaming chips being identical to each other within a defined manufacturing tolerance for the resonant marker and being different from each other beyond the defined manufacturing tolerance for the resonant marker;
a non-transitory computer-readable medium that stores information indicative of at least one resonant response of a valid set of gaming chips, each of the at least one resonant response comprising a respective electromagnetic signature characterized by sustained electromagnetic oscillations at one or more frequencies; 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 comprising a respective electromagnetic signature characterized by sustained electromagnetic oscillations at one or more frequencies.

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.

16. 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 an unmodulated, resonant response from any memoryless resonant markers within a range of the emitted non-optical electromagnetic energy via the at least one antenna; a non-transitory 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 any of the resonant markers are discernibly distinct from the resonant responses of the plurality of resonant markers for which information indicative of the resonant responses has been previously stored in the computer-readable medium; wherein the resonant markers resonate in response to one or more passive electrical components, resonating structures, or resonating materials absorbing non-optical electromagnetic energy and the resonant markers do not include active switches or active circuits; and store information indicative of the received, unmodulated, resonant response that lies within a defined manufacturing tolerance in the computer-readable medium if the received resonant response is discernibly distinct beyond the defined manufacturing tolerance from other resonant responses for which information indicative of the respective received, unmodulated, resonant response has previously been stored in the computer-readable medium. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24)
