Casinos in several states are forbidding gamblers from wearing Google Glass, the tiny eyeglasses-mounted device capable of shooting photos, filming video and surfing the Internet.
Regulators say the gadgets could be used to cheat at card games.
The New Jersey Division of Gaming Enforcement issued a directive on Monday ordering Atlantic City's 12 casinos to bar casino patrons from using the device. The directive was first reported by The Press of Atlantic City.
Similar bans are in place at casinos in Las Vegas, Pennsylvania, Ohio and Connecticut, among other places.
"If these eyeglasses were worn during a poker game, they could be used to broadcast a patron's hand to a confederate or otherwise be used in a collusive manner," David Rebuck, the division's director wrote in a memo to the casinos.
That type of use would constitute a crime in New Jersey. But it would be difficult to establish beyond a reasonable doubt that the glasses were actually being used to cheat, Rebuck wrote.
In a statement issued Wednesday, Google said, "We are thinking very carefully about how we design Glass because new technology always raises new issues." -- AP
