A fingerprint-based attendance system with real-time data logging.
A fingerprint-based attendance system that logs attendance with real-time timestamps.
Manual attendance registers are slow and easy to manipulate; the client needed a tamper-resistant, automated system.
We built a fingerprint-based attendance system using Arduino, where each registered fingerprint logs an attendance entry with a real-time timestamp, stored for later review.
A fingerprint sensor module communicates with the Arduino over serial to enroll and match fingerprints. On a successful match, the Arduino reads the current time from a real-time clock module and logs the entry to storage.
Delivered as a complete working unit with wiring diagram, source code, and a guide for enrolling new users.
