GeoMark // Geo-Verified Attendance
Attendance,Reinvented.
Dynamic QR codes, GPS geo-fencing, and cryptographic audit trails — working as one. Students can't fake it. Admins verify instantly.
Built to beUnbeatable.
Dynamic QR Codes
Rotating tokens refresh every 20–30 seconds. Screenshots become useless. HMAC-signed and single-use.
GPS Geo-fencing
Haversine-accurate distance validation. Only students physically inside the classroom radius can mark present.
Fraud Detection
GPS spoofing analysis, impossible travel detection, and device fingerprinting flag suspicious check-ins automatically.
Device Fingerprinting
Canvas, WebGL, screen resolution, and platform signals uniquely identify each device across sessions.
Real-time Analytics
Live attendance feeds, interactive heatmaps, and automated summaries for instant institutional insight.
AI Assistant
Built-in AI chatbot answers student and staff questions, interprets attendance data, and flags anomalies.
Instant Validation
Sub-500ms attendance recording with real-time feedback. Students know immediately if marked present.
Zero-Trust Security
JWT sessions, HTTP-only cookies, HMAC-signed QR tokens, and a full security event log with severity levels.
How it works.
