Surprisingly, I am almost never asked this question by casino personnel when I give game protection seminars. This is probably because they assume that their tables are protected from pastposting (adding or switching chips after a winning outcome) and pinching (removing or reducing chips after a winning outcome) by gaming chips with RFID chips embedded inside them.
For those of you who do not know how RFID technology functions at the blackjack, craps, roulette and baccarat tables in casinos, it is rather simple. When players place their bets, the dealer pushes a button that activates the RFID mechanism. The RFID chip within the gaming chip registers on a screen at the edge of the table. So if you bet one $25 chip at the blackjack table, the $25 chip will register on the RFID monitor. If you bet five $5 chips, they will all register on the monitor. Same thing if you bet one $100 chip and one $25 chip. The point is that the RFID screen will tell the casino not only how much you bet but exactly which combination of chip denomintations you bet with.
So it this RFID game protection beatable? Can you still pastpost and pinch chips when the casino has your original bets recorded on the monitor?
You may be surprised but the answer is undoubtedly "YES!" I am not going to tell you exactly how it's done because casinos pay me for that type of information...but I will say that you have to set the casino up for this type of move when pastposting. When pinching it is a different story...easier.
If anyone reading this article really is intrigued how to beat RFID technology in this manner, I'll tell you what I'll do. If you tell me how you think it can be beat, I will tell you if you are right or wrong.
