Bally Gaming was demonstrating their newest evolution of their Mind Play, chip recognition system. Instead of requiring a casino to change out their entire rack (as the Las Vegas Hilton did a few years back) to use recognizable chips for the Mind Play optical recognition technology, Bally was demonstrating their hardware can simply recognize a casino's existing chips.

They demonstrated this using these generic, Matsui chips. (Sorry, no traders available.)

If I'm not mistaken, the Las Vegas Hilton switched to this rack (BetG) for the Mind Play optical recognition system.

Thanks for looking!
