Arcade machines are valuable investments, and protecting their internals from tampering is crucial for maintaining fair gameplay and preventing fraud. Anti-tampering seals are widely used to secure arcade cabinets, ensuring that only authorized personnel can access sensitive components. Here are the most common types of anti-tampering seals for arcade machine internals:

1. Destructible Vinyl Seals: These seals tear or break upon removal, leaving visible evidence of tampering. They are often used on access panels and coin doors.

2. Holographic Security Seals: Featuring unique holographic patterns, these seals are difficult to replicate and provide a high level of security against unauthorized access.

3. Tamper-Evident Labels: These labels leave behind a "VOID" message or residue when removed, making it clear if someone has attempted to breach the machine.

4. Metal Security Seals: Made from durable metal, these seals require special tools to remove and are often used for high-security applications.

5. QR Code or Serialized Seals: Each seal has a unique identifier, allowing operators to track and verify the integrity of the seal remotely.

Using these anti-tampering seals helps arcade operators maintain the integrity of their machines, prevent cheating, and protect their revenue. Choosing the right type depends on the level of security required and the specific vulnerabilities of the arcade cabinet.
