Arcade machines, often containing valuable hardware and cash, employ multiple anti-tamper mechanisms to prevent theft, vandalism, and cheating. The most common types include physical security features such as robust locks on coin doors and access panels, frequently using high-security tubular or disc-detainer locks that resist picking. Electronic protection measures involve encryption for firmware and secure boot processes to prevent unauthorized software modifications. Additionally, tamper-evident seals on PCBs and internal components deter component swapping. Environmental defenses like motion sensors or security cameras monitor for physical attacks, while anti-pry brackets and reinforced metal frames protect against forced entry. These layered security approaches ensure arcade operators can safeguard their investments in public settings.
