The advantage of RFID casino chip when players use it:
For table game players, there are two ways that RFID chips can be problematic:
The first is the use of sensors under each betting circle to accurately determine the amount a player is betting. The benefit to the casino is that average bet ratings can be precisely accurate for each player, and they can eliminate the inaccurate ratings that often allow players to earn comps above the appropriate level. See “How a Basic Strategy Player can Beat Blackjack” for more on that. In addition, if this real-time betting data can be coupled withsophisticated surveillance software, the process of detecting many forms of advantage play could be automated.
The second concern is that RFID tags could potentially allow a casino to “assign” chips to a particular player who won them at the table. If the casino knows who you are (or at least has an assigned profile for you), then chips could be tagged to you specifically. If those chips disappear out of the casino inventory for a time, if you like to stockpile chips for future play, this information would be a problem, especially if someone other than the original player eventually plays the chip or cashes it at the cashier.
Fortunately, although the system sellers paint RFID as an extremely capable platform, there are still holes in all of this process. The casino floor is a messy environment for this kind of orderly tracking. Players move from table to table, and chips are in constant motion. The kind of bulletproof tracking that would allow chips to be assigned to specific players with any degree of certainty just doesn’t exist. In my opinion, this will not change in the next few years. An industry representative admitted as much during the G2E session. When asked if the system could assign a chip to a specific player, his response was that “It could be done”, but he said that in a tone that made clear that the technology today falls short of this goal.
