Description
The R307 Optical Fingerprint Reader is a reliable and fast biometric fingerprint identification module designed for secure authentication systems. It uses optical fingerprint recognition technology to capture and process fingerprint images with high accuracy.
The module supports fingerprint enrollment, deletion, matching, and storage directly on the device, eliminating the need for external processing. It communicates via UART (serial) and is fully compatible with Arduino, ESP8266, ESP32, Raspberry Pi, and other microcontrollers.
The R307 is widely used in attendance systems, access control, door locks, security systems, and IoT projects.
