Arcade machines employ advanced anti-counterfeiting measures to prevent the use of fake tokens or cards, ensuring fair gameplay and revenue protection. Tokens often feature unique designs, magnetic strips, or embedded RFID chips that are difficult to replicate. Card-based systems use encrypted data, holograms, or barcodes to verify authenticity. Modern machines may also include sensors to detect weight, size, or material discrepancies in tokens. Additionally, centralized server systems can track card usage in real-time, flagging suspicious activity. These measures help arcade operators maintain security while providing a seamless gaming experience for players.
