Bill Validator Device (Fake Bill Scam)
How it works
Manipulation of the paper voucher system used by modern slot machines. Includes counterfeiting vouchers, exploiting printer vulnerabilities, laundering money through minimal play, and employee ticket overrides. Fraudsters purchase credits with cash, perform minimal play, then redeem TITO tickets for clean payouts (ticket laundering). Criminals may also exploit reprint functions, manual overrides, or exception handling. Counterfeit barcodes on fake tickets have been attempted at redemption kiosks.
On the record
Global gaming enforcement has cited voucher and ticket redemption controls as weaknesses. The NGC Case 18-04 involved a Venetian slot manager improperly handling a $921 TITO voucher. Money launderers routinely use TITO tickets to structure transactions below reporting thresholds.
