Capacitive 360-degree fingerprint sensor (D) with UART

The UART fingerprint sensor is equipped with a powerful Cortex processor and a highly secure fingerprint algorithm. It enables functions such as registration, matching and image capturing, and is suitable for small applications with high precision thanks to simple UART commands. 


Features: 

  • Simple operation through simple commands.  
  • Commercial fingerprint algorithm with stable performance and fast identification.  
  • Capacitive detection for quick validation through light touch. Built-in hardware for small applications.  
  • Stainless steel rim for 360° omnidirectional verification.  
  • Embedded sensor with low power consumption.  
  • Integrated UART port for easy connection to hardware platforms. 

Example Applications for Fingerprint Reader: 

  • Fingerprint lock 
  • Safe box with fingerprint  
  • Access control system with fingerprint scanner 
  • Door lock system with fingerprint 
  • Time attendance system
