Traditional attendance systems are prone to manipulation, buddy punching, and require manual record-keeping, which is time-consuming and error-prone. Institutions and organizations face challenges in maintaining accurate and real-time attendance records. There is a need for an automated and secure system that verifies individual identity uniquely and records attendance efficiently.
This project introduces a fingerprint-based attendance system using a fingerprint sensor module and a microcontroller such as Arduino or ESP32. Each user’s fingerprint is registered and stored in memory. During attendance, the fingerprint is scanned and compared with stored templates. Upon successful verification, the system logs the time and marks attendance, optionally displaying the result on an LCD and saving data to a database or SD card. It ensures secure, tamper-proof attendance with minimal supervision.
