1. A system for identifying and reading gaming tokens, the system comprising:
a plurality of gaming tokens, each gaming token comprising:
a substrate having first and second faces and a perimeter;a circuit including a power source, token processor, and token memory disposed in the substrate, the memory configured to store data that identifies at least a denomination of the gaming token;first and second conductive layers disposed on the first and second faces respectively, anda conductive rim at the perimeter; a playing surface including a network of conductors disposed to make electrical contact with the conductive rims of the gaming tokens that rest thereon and ground the circuits to energize the processor; one or more transceivers disposed under the playing surface and associated with areas where the gaming tokens are placed on the playing surface, each transceiver configured to transmit an electromagnetic interrogation signal to the conductive layer of a gaming token resting on the playing surface, the grounded circuit in response to the interrogation signal responding with data to identify the chip denomination through capacitive coupling between the conductive layer and a transceiver; and an identification processor in communication with the transceiver to determine the denomination of the gaming token from the data. |
