Here's the problem.
First of all, some casinos also use RFID readers inside of the chip tray. So, if a wager lost, the discrepancy would be detected immediately, as soon as the dealer placed the losing wagers into the chip tray. But, RFID technology is sold as optional features. This means that a casino can pick where to install the readers. In theory a casino could opt for having readers under the betting spots and no readers under the chip tray. It boggles the mind why any casino would ever consider such option, but (at least in theory) anything's possible. cheat cards
But even if a gaming table in some casino is not fitted with RFID readers in the chip tray, there is another problem. If a fake chip ends up in the tray, it will be detected as soon as the dealer uses that chip to pay any legitimate winning bet. So, the lifespan of this fake chip may be very short.
But as I mentioned before, the developers of RFID technology already thought of this hypothetical scam, so they came up with a solution. All the RFID enabled tables have shields under the readers. So, if you place a genuine RFID chip under the table, the reader doesn't pick it up.infrared contact lenses
Are there any other possible scams that involve RFID chips? Well, I am told that many casinos that acquired the RFID technology have had problems with it. I even know one actual casino that disabled their RFID readers because they had too many problems with the technology. I know which casino it is, but I will not divulge the information here. It would seem that the RFID technology works well in laboratory conditions, but when it hits the casino floor there are bugs that slow down the operation. And in casino land, when you slow down the tempo, it is the long term equivalent of shutting down the joint a few weeks in a year. And a casino that is not open for business is losing money; losing by not wining to its full potential. And since casino business is all about money, some have come to the conclusion that the cost of RFID technology goes beyond what they pay to acquire it.
