Abstract
A system is disclosed for identifying and reading gaming tokens. The system includes: a plurality of gaming tokens; a playing surface including a network of conductors disposed to make electrical contact with the conductive rims of the gaming tokens; one or more transceivers disposed under the playing surface and associated with areas where the gaming tokens are placed on the playing surface; and an identification processor in communication with the transceiver to determine the denomination of the token from the data. Each transceiver is 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, responds with data to identify the chip denomination through capacitive coupling between the conductive layer and a transceiver.
