Uses of Copper Powder in the Entertainment Sector

Copper Powder in Gambling Chips

RFID or radio frequency identification technology is an emerging anti-counterfeiting technology in the gaming industry.  Small antennas, typically fabricated from copper are embedded into the chip.  This allows the chip to receive a signal from a reading device and return a response, which is often a numerical code akin to a serial number.  Copper-based coating materials are ideal for these applications because they are relatively inexpensive, excellent conductors of radio waves, and can easily be processed in such a way as to accommodate the miniature circuitry requirements.
