Mind Play does not track from a computer chip in the chip. It tracks from cameras in the rails.
It tracks from the edge spots on the chips.
The edge spots on BJ chips are always the same, unlike Paul-Son that are all different sizes.
The Palms is looking at Mind Play at this time. It is the ONLY player tracking system that works.

All H&C chips are PS since the 60's.
Actually PS sold more Christy Jones H&C chips in a few years after they bought it out than CJ ever thought of selling in some 20 years.
