Casino chips (also known as poker chips, gaming tokens, or checks/cheques) are small discs used as currency in casinos. Larger, rectangular gaming plaques may be used for high-stakes games. Poker chips are also widely used as play money in casual or tournament games, are of numismatic value to casino chip collectors, or may be kept as souvenirs.
Chips and plaques used in table games may be made of a mixture of metal, clay, ceramic, and plastic materials inlayed or painted with colors and numbers indicating various denominations, while metal token coins are used primarily in slot machines. Some casinos embed RFID tags into chips to collect data and fight counterfeiting, and plaques may have printed serial numbers.
