Australian Andrew Milner built a poker table equipped with RFID chips for every single card and HD cameras to track every movement. His setup can even tell where cards lie in a full, vertical deck.
Apparently the setup cost Milner about $7000 and three months to build, but it's very impressive for what it is. Why anybody would want to have this sort of thing outside a television studio doesn't make much sense to me, but Milner, a chairman of an IT company, loves the level of detail it brings to his games.
