Modern casino chips are protected using high-tech devices like RFID (Radio Frequency Identification) technology. This involves embedding a small electronic chip within the casino chip that can be tracked and identified. RFID scanners are used at both gaming tables and the cashier's cage to ensure that a low denomination chip cannot be mistaken for a high denomination one, regardless of what the face of the chip reads. This technology makes it nearly impossible for counterfeit chips to be used undetected within the casino.
