UART Fingerprint Reader is a fingerprinting module designed for secondary development, high-speed for identification, high stability. It is an intelligent module that provides functionalities like fingerprint recording, image processing, feature extraction, template generation, template storage, fingerprint matching and searching, etc.
- Onboard high-speed processor STM32F205
- Commercial fingerprinting algorithm, faster identification
- High-accuracy optical sensor, standard 16-pin interface, allows users to choose optical/semiconductor sensors
- Divided structure: fingerprint sensor + processing circuit + algorithm platform
- Easy for developing, controlled via UART, supports any MCU with UART
- Open protocol, it's available to freely input/output fingerprint images, fingerprint feature file and other fingerprinting actions
- Fingerprint lock
- Fingerprint safe deposit box
- Access control system
- Person identification
- Authority management
