Attendance,Reinvented.
Dynamic QR codes, GPS geo-fencing, and cryptographic audit trails — working as one. Students can't fake it. Admins verify instantly.
Built for the modern institution
Every feature engineered for security, speed, and scale — from a small classroom to a university campus.
Dynamic QR Codes
Rotating QR codes refresh every 20–30 seconds. Screenshots are useless. Real-time token signing ensures zero reuse.
GPS Geo-fencing
Validate attendance only within a configurable radius. Haversine-accurate distance calculation rejects students outside the classroom.
Smart Fraud Detection
GPS spoofing detection, device fingerprinting, and impossible travel analysis flag suspicious check-ins automatically for instructor review.
Device Fingerprinting
Canvas rendering, WebGL, screen resolution, and platform signals combine to uniquely identify each device.
Real-time Analytics
Live attendance feed via Socket.io. Interactive charts, heatmaps, and automated summaries for admins.
Zero-Trust Security
JWT sessions, HTTP-only cookies, HMAC-signed QR tokens, and a full security event log with severity levels.
Instant Validation
Sub-second attendance recording with optimistic UI feedback. Students know immediately if they're marked present.
Google OAuth
Secure sign-in with verified Google accounts. Role-based access for admins, instructors, and students.
