Waveshare Fingerprint Reader Sensor Module (UART)

This professional fingerprint module from Waveshare is a high accuracy and reliability biometric reader with an STM32F205 processor and a commercial-grade fingerprint algorithm at its heart. Unlike entry-level modules such as the AS608, it can store up to 1000 fingerprint templates and offers 10 software-customizable security levels from 1 to 10, with a false acceptance rate of less than 0.001% and a false rejection rate of less than 0.1%. The open source protocol allows not only enrollment and verification but also direct access to the raw fingerprint image, fingerprint characters and processing steps. With a wide supply range from 3.3V to 7.5V and UART communication, it is compatible with all development boards such as Arduino, ESP series and Raspberry Pi. With a reading and matching time of less than 0.5 seconds, a sensor surface resistant to 1 million readings and a template format in accordance with ISO19794-2 standard, it is a high-end solution designed for commercial access control systems, authorization management and personnel tracking applications.
