Capacitive Fingerprint Reader (B)

precise fingerprint identification | UART/USB dual ports

Product Features

The Capacitive Fingerprint Reader (B) is a fast and stable capacitive fingerprint module specialized for secondary development, suits integration applications. By incorporating high performance Cortex core processor, high security commercial fingerprint algorithm, and advanced semiconductor fingerprint sensor, this module is designed as a intelligent integration module with functions including fingerprint enrolling, image processing, template generating and storing, fingerprint matching and searching, etc.

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 identification
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
Comes with rich development resources (related command documents, tools, and examples for Raspberry Pi/Arduino/STM32)
