A recent G2E conference session in Las Vegas gave me a chance to hear industry insiders talk about the current usage of RFID (Radio Frequency ID) technology inside casinos. This technology uses radio tags embedded in casino chips to authenticate the chips, and to enable more accurate data gathering on the casino floor. The idea has been around for a number of years now, with Wynn Las Vegas using the system since 2005. In the years since, the technology has slowly improved and more casinos have begun to use the chips. An expert speaker at the conference indicated that perhaps 40 casinos in the US are currently utilizing radio-enabled chips.
