maybe I don't fully understand the technology, but it looks to me to be similar to mindplay. I dont see how either "is the end of advantage play if used legally" A computer is tracking your play rather than a human. It still will take a number of hands, perhaps shoes to determine if a player is moving his money with the count. So if you play anonymously and keep your sessions short, no difference. Now if they use this technology to signal the dealer and shuffle when each time the count goes positive, then that's a whole different story. They are crossing the line of whats legal. Of course it may take several court cases to stop that behavior.
