CNC Machine Biometric Fingerprint and Card Locking Security System is a specialized access control solution designed to restrict unauthorized programming and operation of CNC machines. By integrating biometric fingerprint recognition and RFID card authentication, the system ensures that only authorized operators can access the control panel or make programming changes. It enhances workplace safety, prevents misuse of machines, and maintains production integrity. The system supports multi-level access rights, allowing supervisors, operators, and technicians to have different levels of control. With options for audit trail logs, administrators can monitor who accessed the machine and at what time, providing full accountability. This advanced locking and access control solution is suitable for industries such as automotive, aerospace, manufacturing, and precision engineering, where CNC programming security is critical.
