Slot Machine Bill Validator Device

As slot machines have gotten more sophisticated, so have the cheating methods. In the old coin slot machines, cheaters could attach a piece of string to the coin, with a paper clip on the end to prevent it from falling into the hopper.

The newest way to scam slot machines involves a small computer device that tricks the bill validator. The device, usually disguised by a $1 bill, has two prongs that are inserted into the bill validator. Once they hit the contact point below the validator, the slot machine will read any bill that’s inserted as a $100 bill. The most recent devices don’t even need another bill to work — instead they just add credits after hitting the contact point in the slot machine.

However, casinos have caught on and the scam is less common than it once was. Slot machines have now been retrofitted so that the devices won’t work, according to the Nevada Gaming Control Board. So the only way for a cheater to use the device is to find a machine that hasn’t been updated.
