Taking a break

 We're taking a break moving shop and hope to be back soon. We hope to start shipping orders in Nov 2018. 

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
