a little further detail
Besides everything Coug Fan mentioned.
Mindplay will actually cut the comps of many players because it is slow (less hands), will total your bets to the cent, where a favorable pit might give you extra, not give you credit for any time where you did not place a bet (bathroom and cell phone brakes etc)
It has in fact been used to shuffle early at the El Dorado in Reno.
It was not successful when it was at the LVH
Though many pit and surviellance types are not smart enough to realize it yet, the biggest savings to the casino using Mindplay is the cutting of both staffs. You no longer need as many people because the machine will total the bets, catch the cheats, evaluate the players, make sure the dealer is not cheating and so forth. One must wonder how many holes it in fact leaves once the staffs are cut, I can think of several possibilities.
There are now other firms planning similar types of systems. Seems if you can come up with a product that appeals to the two huge things when selling to a casino, effective or not, if the players will play on it or not, you will make a ton in sales.
Those two huge things of course are casino paranoia and greed.
