Anti-tamper seals are essential for maintaining the integrity and security of arcade machines, preventing unauthorized access or tampering with internal components. Here are the most common types of anti-tamper seals used in arcade machines:

1. Destructible Vinyl Labels: These seals break apart when removed, leaving visible evidence of tampering. They are often used on access panels and critical components.

2. Void Security Labels: These labels leave a "VOID" or custom message when peeled off, making it clear if someone has attempted to tamper with the machine.

3. Holographic Seals: Featuring intricate holographic patterns, these seals are difficult to replicate and provide a high level of security against counterfeiting.

4. Tamper-Evident Tapes: These adhesive tapes tear or show signs of removal when disturbed, often used to secure wiring or smaller components.

5. RFID Seals: Advanced seals with embedded RFID chips can trigger alarms or log tampering attempts electronically, offering enhanced security for high-value machines.

By using these anti-tamper seals, arcade operators can protect their equipment from unauthorized modifications, ensuring fair play and longevity of the machines.
