Regulators say the devices could be used to cheat at card games.
The New Jersey Division of Gaming Enforcement issued a directive this week 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.
Several casinos in Las Vegas, including ones owned by Caesars Entertainment and MGM Resorts, have directed their security workers to ask patrons to remove the devices if they suspect the person is using it to secretly photograph or take video recordings.
