Brain-computer interface (BCI) technologies could potentially enable undetectable dealer collusion signaling by:
1. Thought-based communication: Dealers and players could communicate using thought-based communication methods, such as subvocalization or neural decoding, which are difficult to detect by surveillance.
2. Neural implants: Dealers or players may choose to implant BCI devices in their brains, which could allow them to communicate directly without any visible signs of communication.
