Arcade machine coin doors are critical for securing coins and preventing unauthorized access. To enhance durability and security, several reinforcement methods are commonly used:

1. Metal Reinforcement Plates: Thick steel or aluminum plates are often installed behind the coin door to prevent bending or tampering. These plates distribute force evenly, making it harder to break in.

2. Heavy-Duty Locks: High-quality locks, such as cam locks or deadbolts, are essential for securing the coin door. These locks are resistant to picking and drilling, providing an extra layer of protection.

3. Reinforcement Brackets: Metal brackets are added to the door frame or hinges to strengthen weak points. These brackets prevent the door from being pried open easily.

4. Tamper-Proof Screws: Specialty screws with unique heads (e.g., Torx or security screws) are used to deter tampering. These screws require specific tools to remove, making unauthorized access difficult.

5. Coin Box Security: Some setups include a secondary locking mechanism for the coin box itself, ensuring coins remain secure even if the outer door is compromised.

By combining these reinforcements, arcade operators can significantly improve the security and longevity of their coin doors, protecting both revenue and equipment.
