Arcade PCBs (Printed Circuit Boards) are critical components in gaming machines, making them a prime target for counterfeiters. To combat fraud, manufacturers implement various anti-counterfeiting measures. Here are the most common types:

1. Holographic Stickers and Labels: These are applied to PCBs and change appearance when viewed from different angles, making them difficult to replicate.

2. Unique Serial Numbers: Each PCB is assigned a distinct serial number, allowing verification of authenticity through databases or scanning tools.

3. Encryption and Secure Chips: Advanced PCBs use encrypted firmware or secure microchips to prevent unauthorized duplication or tampering.

4. Tamper-Evident Seals: These seals break or leave marks if removed, indicating potential tampering or counterfeit replacement.

5. Customized PCB Designs: Manufacturers may use proprietary layouts or obscure component placements to deter cloning.

6. UV Markings: Invisible ink markings visible only under ultraviolet light help verify genuine products discreetly.

By combining these methods, arcade PCB manufacturers can significantly reduce counterfeiting risks, ensuring the longevity and integrity of gaming hardware.
