Manufacturers employ a variety of strategies to combat counterfeit or unauthorized copies of arcade machines, ensuring the integrity of their products and the gaming industry. One common method is the use of proprietary hardware and software, such as custom circuit boards or encrypted firmware, which are difficult to replicate. Additionally, manufacturers often embed unique identifiers, like serial numbers or holographic stickers, to verify authenticity.

Legal protections, including patents, trademarks, and copyrights, are also crucial. These measures allow manufacturers to take legal action against counterfeiters. Some companies even implement online verification systems, requiring arcade operators to register their machines to access updates or support.

Another approach involves partnerships with distributors and retailers to monitor the supply chain, ensuring only authorized units reach the market. Advanced technologies, such as RFID chips or blockchain tracking, are increasingly used to enhance traceability. By combining these methods, manufacturers effectively deter counterfeiting and protect their intellectual property.
