Short of implanting a chip in a player it would be difficult to track who has the chips. Certainly they could say where on the floor the chip or chips are. They could check how many chips have left the premises. Also in this type of RFID the range is a problem so when you see liitle radar stations springing up you know its on.
Now a passable scheme would be if the players card had a RFID and when $1000 chips are purchased the card and chip pile could be read together but then as chips are lost and won the person holding the chip would change certainly more so for lower level chips. Also a player would have to have their card on them at all times while playing.
It would be hardly be workable for $5 and $25 chips. They profess that it would increase number of rated players but this does not sound feasible.
I will quietly mull over possibilities as this is off the top of my head.
