SCAM #28: TITO Ticket Counterfeiting & Replication

How it works

Ticket-In, Ticket-Out (TITO) systems replaced coin hoppers with printed vouchers that players use to cash out and move between machines. Criminals attempt to: (1) counterfeit TITO tickets by replicating barcodes/QR codes and security features, (2) use ticket printer vulnerabilities to generate duplicate tickets, (3) exploit race conditions where tickets are cashed multiple times at different locations before the central system updates, (4) intercept tickets from the printer output and replace them with lower-value counterfeits while keeping the original. Modern TITO systems use encrypted validation codes and centralized databases to prevent counterfeiting, but vulnerabilities in implementation — especially in older systems or improperly configured installations — can be exploited. Some attacks target the ticket printer itself, using electronic devices to trigger unauthorized ticket printing.

On the record

TITO fraud has been a concern since the technology’s widespread adoption in the early 2000s. Various incidents of ticket counterfeiting and duplication have been documented across multiple jurisdictions. As TITO systems have become more secure, attackers have shifted to targeting the underlying infrastructure rather than the tickets themselves.
