RFID Card Swapping
How it works
A technique where cheaters secretly replace a standard deck with an RFID-enabled deck that can be read by concealed scanners, giving them knowledge of all cards in play. An accomplice working at the venue or a player with access swaps the casino’s regular cards for a special deck containing RFID tags. A concealed reader in a bag scans the cards. Prosecutors have also alleged a camera-fitted chip tray, a different device. The information is relayed to the cheater’s a confederate by cellphone, as prosecutors have alleged in a separate card-reading case.
On the record
In 2025, three players at JokerStars Poker Room in Houston were caught after a security review found Carlito had swapped regular cards for an RFID-enabled deck, while a card-reading device was hidden in his backpack. A concealed card-reading device completed the system. The club banned Carlito for life and returned money to affected players.
