Abstract
A method and apparatus to prevent fraud in a bill acceptor system utilizing a lockable, removable cassette is disclosed. A security arrangement including a security sensor and a microprocessor monitors the attachment of the cassette for proper installation, and monitors the bill pusher cycle when an accepted bill is loaded into the cassette. If the cassette is not properly installed or if a bill pusher cycle fails to complete, indicating a possible fraud attempt, then the bill validator is disabled.
