NFC Attendance System
“Tap to Clock In. No Friction. No Paper.”
Built with Next.js 15 and Turso SQLite, this system handles NFC tag enrollment, real-time attendance tracking, role-based access, and offline buffering with automatic sync. Includes a Progressive Web App for mobile NFC check-ins.
Problems we solved
Hardware Integration
Physical NFC readers (USB/Ethernet) needed a bridge between hardware events and the web application.
Offline Reliability
Network drops in factories and warehouses meant check-ins would fail. Attendance data is too critical to lose.
Role Complexity
Admin, HR, Reader devices, and Employees all need different access levels with secure session management.
How we built it
NFC tap-to-check-in with offline buffering, RBAC, and a real-time admin dashboard with CSV export.
