Evolution of Biometric Tracking in Polytechnic Education
To eliminate proxy attendance and ensure institutional accountability, SBTET transitioned through multiple technological phases—from paper roll calls to wall-mounted optical fingerprint sensors, and now to mobile-based Facial Recognition Systems.
Fingerprint Biometric vs. Facial Recognition System (FRS)
| Parameter | Optical Fingerprint Machine | Mobile / Tablet FRS |
|---|---|---|
| Capture Time | 2–4 seconds per student | Under 1 second per student |
| Maintenance | Frequent sensor glass wear & tear | Software updates via Google Play / APK |
| Hygiene | Contact-based physical touch | 100% contactless facial scan |
| Sync Delay | Nightly batch FTP transfer | Near real-time HTTPS REST API |
