Part I: Card Game Cheating · Collusion & Electronic Cheating at Card Games

Scam #25: Vibrating/Signaling Button Devices

How it works

Small electronic devices hidden on a cheater’s person (in pockets, shoes, belts, or clothing) that receive signals from an accomplice and communicate through vibrations. One buzz might mean “bet,” two buzzes “fold,” three buzzes “raise.” The accomplice may have access to hole card information through hidden cameras, shuffler hacking, or other means. These devices are specifically designed to be undetectable to surveillance and can only be found through physical pat-downs or electronic sweeps. Some require magnets for removal, making them nearly invisible.

Where it appears

Poker, blackjack, baccarat, any card game

On the record

In 2026, Jeremiah Villegas was convicted for using a vibrating device at Northern Quest Casino. French police arrested two men in 2024 who used James Bond-style tiny earpieces requiring magnets for removal. Signaling devices are widely available online marketed for “exam cheating” and easily repurposed for casino use.
