Abstract:
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; 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.
