Attendance,Reinvented.
Dynamic QR codes, GPS geo-fencing, and cryptographic audit trails — working as one. Students can't fake it. Admins verify instantly.
The whole idea
A check-in nobody can forge.
Three independent proofs, checked in under a second. Miss one and you're not marked — no proxy, no screenshot, no shortcut.
Everything you need
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.
From arrival to insight
A closed loop that never breaks — every step verified, every record immutable.
Every layer of protection
Six interlocking systems that make attendance fraud impossible — from the classroom to the parent's phone.
Dynamic QR Attendance
Rotating QR codes refresh every 20–30 seconds. Screenshots are useless — every scan is cryptographically signed and one-time-use only, so sharing codes never works.
GPS Geo-fencing
Students can only check in when physically inside the classroom boundary. Haversine-accurate distance validation rejects anyone outside the configured radius instantly.
Multi-Layer Fraud Detection
GPS spoofing detection, device fingerprinting, and impossible travel analysis automatically flag suspicious check-ins and route them to the instructor for review.
Biometric Fingerprinting
Canvas rendering, WebGL entropy, screen resolution, and platform signals combine into a unique device signature — making proxy attendance impossible to pull off.
Real-time Analytics
Live attendance feeds, interactive charts, heatmaps, and automated summaries give admins and lecturers full visibility into every session as it happens.
Instant Parent Notifications
Parents receive real-time alerts the moment their ward marks attendance or is flagged absent — keeping families connected to campus accountability.
Four layers of proof
Every check-in, verified
