File:TArduinoFingerprintScanner.png

Summary

Serial fingerprint scanner/reader with template management, enrollment capabilities, and configurable security features.

Description

The Fingerprint Scanner/Reader component provides biometric authentication through serial communication. It supports fingerprint enrollment, template management, verification, and advanced security features including backlight control, password protection, and random number generation. The scanner can store multiple templates, perform 1:1 and 1:N matching, and includes comprehensive error handling. Typical applications include access control systems, time attendance systems, and secure authentication platforms.
