Waveshare 13694 Capacitive Fingerprint Reader
Description
The Capacitive Fingerprint Reader is a standard fingerprinting module designed for secondary development, allows fast and stable fingerprint verification.
Based on a high-speed digital processor STM32F105R8, combined with high-security commercial fingerprinting algorithm, and advanced semiconductor sensor, the Capacitive Fingerprint Reader becomes a simple but smart integration module, provides functionalities like fingerprint enrolling, image processing, feature finding, template generating and storing, fingerprint matching and searching, etc.
Features
- Easy to use by some simple commands, you don't have to know any fingerprint technology, or the module inter structure/calculation
- Commercial fingerprinting algorithm, stable performance, fast verification
- Sensitive detection, just touch the collecting window lightly, without pressing
- Allows to freely input/output fingerprint images, fingerprint feature file and other fingerprinting actions
- Dual communication, UART or USB
- Processor will enter sleep and wake up when detecting, achieves low power consumption
- Comes with rich related resources (software on PC, development SDK, tools, and examples for Raspberry/Arduino/STM32)
Applications
- Fingerprint lock
- Fingerprint safe deposit box
- Access control system
- Clock in and out
