Insider theft — cheating committed by current or former employees — is one of the hardest security problems to solve in a coin pusher venue. The employee has legitimate access to the machines, understands the daily procedures, and can cover their tracks in the daily reconciliation. I have investigated 14 cases of insider theft on coin pusher and token machines across different venue types. In each case, the operator was surprised to learn that someone they trusted was responsible.
How Insider Theft Works on Coin Pushers
The most common insider method is the manual payout. During off-hours — after closing, during a break, when the venue is quiet — the employee opens the machine and directly removes coins or tokens from the playfield or the hopper. They then adjust the machine’s meter readings or the daily cash report to hide the loss. Because the employee has access to both the machine and the records, this method can continue for months without detection.
A second method is the fake coin injection. The employee uses a coin pulse device — the same type used by external cheaters — to generate free credits for friends or for themselves during their shift. The pulse device is small enough to conceal in a pocket and can be used while pretending to check on the machine. The employee does not need to open the cabinet, which reduces the risk of being caught on camera.
The third method is the information leak. The employee does not cheat directly. Instead, they provide machine passwords, cheat device access, or operational timing information to external cheaters in exchange for a cut of the stolen value. This is the hardest method to detect because the employee never touches the machines during the cheating incident.
How to Prevent Insider Theft
Coin-level anti-cheat protection is the most effective countermeasure against insider theft, including employee theft. The Gen2 device blocks fake coin pulses regardless of who initiates them. It also monitors machine access events — every time a cabinet is opened, the event is logged. This creates an audit trail that deters employees who might otherwise steal during off-hours.
Additionally, the Gen2 system’s alert function can be configured to notify a manager whenever a machine’s payout settings are changed. This prevents an employee from adjusting the payout percentage through a diagnostic menu — a method used in several insider theft cases I have investigated.
If your coin pusher or token machine is showing signs of insider theft or employee-related revenue loss, send me a message with your machine model and a photo of your setup. I will do a quick remote check for free. Every device comes with a money-back guarantee, official invoice, express shipping, and 1-on-1 technical support.

Frequently Asked Questions
Q: How do I know if the theft is from an insider versus an external cheater?
A: Insider theft typically happens outside of regular operating hours or when the employee has unsupervised access. External cheating happens during operating hours. The Gen2 system logs every blocked attack by timestamp, which helps distinguish between the two.
Q: Should I change my access control procedures before installing anti-cheat?
A: Access control is valuable, but it does not stop an employee who already has legitimate access. The Gen2 system adds a monitoring layer that works regardless of who has physical access to the machines.
Q: Can the Gen2 system detect an employee who is providing information to external cheaters?
A: The system cannot read intentions, but it provides the data trail you need. If an external cheater’s attacks coincide with a specific employee’s shift, the logs will show the correlation.
Q: Will the anti-cheat device help me prove an employee is stealing?
A: Yes. The logs provide documented evidence of blocked attack attempts, machine access events, and configuration changes. This data can be used in internal investigations or legal proceedings.
