Hey Product Hunt! š I'm Nitin Dubey, the creator of PrezScan.
Colleges spend lakhs on wall-mounted biometric kiosks that create long morning queues and still fail to stop proxy attendance. I built PrezScan (https://prezscan.onrender.com) as a 100% free, zero-hardware alternative that runs directly in any smartphone browser:
ā On-Device WebGL Facial Biometrics (<200ms): 68 facial landmarks + 5-point affine head-tilt alignment + CLAHE lighting normalization + 128D ResNet embeddings running locally ā no raw photos sent for matching.
ā Dual Anti-Proxy Lock: Attendance requires both authorized campus building Wi-Fi subnet verification AND mandatory live device GPS coordinates.
ā Bonus Free Tool ā Net Speed Test & Public IP Checker (https://prezscan.onrender.com/check-ip): Check your real-time Download & Upload Mbps, Ping, Jitter, ISP, and Public IPv4/IPv6 in one fast, zero-ad dashboard!
(Note: PrezScan is an independent platform engineered from scratch ā not affiliated with Prezence.)
Would love your feedback on both the biometric speed and the net speed diagnostic tool! š
