A chip becomes a signal, not just a marker
Inside some high-value casino chips is a tiny RFID tag. RFID, short for radio-frequency identification, lets a nearby reader recognize a tag by sending and receiving radio signals. The tag carries an identifier; it does not need a battery or a GPS device to report its location. Readers placed at points around a casino can register a tagged chip as it passes, helping staff verify where it is and whether it belongs there.
That changes the job of the chip. Its visible denomination still tells players how much it represents, but its electronic identity gives the casino another way to check that it is genuine. A convincing-looking counterfeit may imitate the color and design; it cannot necessarily reproduce the identifier the casino’s system expects.
How a stolen chip can lose its value
If a chip is reported stolen, security can flag its identifier in the casino’s system. When the chip is later presented or detected by a reader, staff can be alerted and refuse to honor it. The chip itself is not remotely melted or physically altered: what gets switched off is its acceptance by the casino’s system.
That distinction is the point of the safeguard. A thief might carry away a small, portable object, but cashing it in requires the casino to treat it as valid. Electronic identification gives staff a way to connect that object to a record—and to make the record, rather than the chip’s appearance, decisive.
