Arcade machines, both classic and modern, represent significant investments for operators. Protecting these assets from theft, vandalism, and unauthorized manipulation is paramount. A multi-layered security approach is standard, combining physical and electronic measures. The most common physical security feature is the robust locking system on the coin door. These high-quality locks prevent access to the cash box and internal components. Many cabinets also feature additional locks on the back door or control panel. To deter entire cabinet theft, heavy-duty security brackets that bolt the machine to the floor are often used. Internally, electronic security is crucial. Anti-tamper software monitors the game's operation, logging errors or attempts to access diagnostic menus without proper codes. Some systems have built-in alarms that trigger if the machine is tilted or moved violently. On the hardware side, security screws that require special tools to remove are common, preventing easy access to printed circuit boards (PCBs). Tamper-evident seals are also placed on critical areas to show if unauthorized entry has occurred. Together, these features create a comprehensive defense system for arcade machines.
