A comprehensive university-wide One Card System, revolutionizing campus services by unifying access to library, dormitory, registrar, cafe, and gate facilities through a centralized authentication framework. This integration significantly boosted operational efficiency and elevated the student experience by simplifying daily interactions. I incorporated advanced Dahua facial recognition terminals and automated doors, ensuring secure and seamless authentication across all campus touchpoints. By consolidating multiple service access points into one platform, I reduced administrative overhead and improved usability for users and staff alike. The system's scalable architecture supports real-time identity verification and robust access control, adaptable to various departmental needs. This project not only streamlined campus operations but also set a benchmark for secure, integrated systems in educational institutions.
