Part I: Card Game Cheating · TEAM PLAY AND COMMUNICATION METHODS

Earpiece Communication with Off-Site Analyst

How it works

Modern cheating teams use miniature earpieces (some requiring magnets to remove) to receive instructions from an off-site accomplice who analyzes the game via concealed camera feed. The earpiece receives audio via Bluetooth or inductive coupling. The accomplice may be in a nearby vehicle, hotel room, or even another country using streaming technology. The earpieces are so small they are invisible to casual observation. Some models are designed to be inserted deep into the ear canal and can only be removed with a magnetic tool.

On the record

In the 2024 French casino case, police recovered a hearing device “so small that you can’t take it off with your fingers - you need a magnet to pull it off. It looks like a typical James Bond movie device.” Similar devices have been found in exam-cheating scenarios and adapted for casino use.
