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
