Bill acceptor cheating on fish tables targets the pulse line — the electrical connection between the bill acceptor and the main board. When a bill is inserted and validated, the acceptor sends a pulse to the board to register the credit. A cheater who can generate a fake pulse on this line can register credits without inserting any money. ICT and PTI are two common bill acceptor brands that are frequently targeted.
How Bill Acceptor Pulse Cheating Works
The cheater uses a small electronic device — a pulse generator — that connects to the bill acceptor’s pulse line. The pulse generator can be as simple as a modified TV remote or a purpose-built device with a button that, when pressed, sends an electrical pulse identical to the one a real bill would generate. The device is small enough to conceal in a pocket and can be triggered while the cheater’s hand is near the machine’s bill slot.
The cheater does not need to open the cabinet. The pulse line is accessible at the bill acceptor itself, which is mounted on the cabinet exterior. A small clip-on tap connects to the pulse line in seconds.
ICT and PTI-Specific Vulnerabilities
ICT bill acceptors use a specific pulse protocol that is well-documented in online forums. The pulse width and voltage are known, making it easy for cheaters to build compatible pulse generators. PTI acceptors use a different protocol but are equally well-documented. Both brands have been targeted extensively.
How to Stop Bill Acceptor Cheating
The Gen2 device’s bill acceptor protection module monitors the pulse line continuously. It analyzes each pulse’s electrical characteristics — voltage level, pulse width, and timing relative to the previous pulse. If a pulse does not match the expected signature of the specific acceptor brand (ICT or PTI), it is blocked before reaching the main board. The module is compatible with both ICT and PTI acceptors and installs in under 20 minutes.

Frequently Asked Questions
Q: How can I tell if my bill acceptor is being pulsed?
A: Compare the machine’s credit count against the actual bills in the cash box. If the machine registered more credits than the bills account for, fake pulses are being injected.
Q: Can the Gen2 device distinguish between ICT and PTI pulse signatures?
A: Yes. The module is pre-configured with the pulse signatures for both brands. It validates each pulse against the correct signature.
Q: Does the bill acceptor protection module affect normal bill processing?
A: No. The module adds no delay to legitimate bill processing. Bills are validated and credited at normal speed.
Q: Can the module be installed on machines that use coin acceptors instead of bill acceptors?
A: Yes. The same module works with coin acceptor pulse lines. The principle is identical.
