As of now, there is no evidence that poker chips have RFID tags. However, this does not preclude the possibility that they do.
Poker chips are made of plastic and metal, so they are susceptible to having RFID tags embedded within them. If this were to happen, it would allow casinos and other gambling establishments to track the movements of their customers and players more effectively.
There is also the potential for casinos to use RFID tags to track the value of poker chips. This could be done in order to ensure that customers are not cheating or defrauding the establishment by exchanging chips with higher value for less.
It is also possible that casinos could use RFID tags to keep track of inventory. If a chip is missing, for example, it might be possible to track down its whereabouts using an RFID tag.
However, we cannot say for sure whether poker chips have RFID tags or not. It is possible that this technology does not exist yet, or that it has not been implemented in a widespread way.
Until such time as we know for certain, we should treat any claims about poker chips having RFID tags with skepticism.
