Abstract:
Gaming chips are provided with embedded radio frequency identification (“RFID”) tags incorporated into a gaming chip for identifying and tracking the gaming chips within a casino, and even upon a gaming table. The gaming chips have a body in the shape of a disc which has a loss tangent of 0.0078 or less, and more preferably of 0.007 or less. For chips operating at 900 MHz, the body has a dielectric constant of 5 or less, and preferably 3-5. For chips operating at 2.45 GHz, the body has a dielectric constant of 5-8. Preferably, the body is made of a blend of plastic, such as PVC, and a dielectric ceramic. The RFID is preferably sandwiched between layers of a high frequency circuit material including top and bottom layers and a center layer have a hole for receiving the RFID. Preferably, the layers of high frequency circuit material have a dielectric constant of 2.5-4 and a loss tangent of 0.002-0.006.
