Arcade machine coin mechanisms are critical components that ensure smooth operation and prevent fraud. Over time, wear and tear or tampering can compromise their functionality. Here are the most common types of reinforcement used to enhance their durability and security:

1. Metal Plate Reinforcement

Adding a sturdy metal plate around the coin slot prevents forced entry and tampering. This is especially useful in high-traffic arcades where machines are prone to abuse.

2. Anti-Fish Plates

These thin, perforated plates block tools like wires or strings used to retrieve coins fraudulently. They are often installed inside the coin chute.

3. Upgraded Coin Acceptors

Modern coin acceptors with microprocessors can detect counterfeit coins and reject them, reducing revenue loss. They also feature reinforced housings for added durability.

4. Locking Mechanisms

Heavy-duty locks secure the coin box and access panels, deterring theft. Some models use electronic locks for added security.

5. Rubber Gaskets and Shock Absorbers

These reduce vibration and noise while protecting internal components from damage caused by rough handling.

Regular maintenance, such as cleaning and lubrication, also extends the lifespan of coin mechanisms. By implementing these reinforcements, arcade owners can ensure reliable performance and minimize downtime.
