This is a highly integrated rectangle-shaped all-in-one capacitive fingerprint sensor module, which is designed in small form factor. The module is controlled via UART commands, fairly easy to use. It's advantages includes fast verification, high stability, and low power consumption, etc.
Based on a high performance Cortex processor, combined with high-security commercial fingerprinting algorithm, the UART Fingerprint Sensor (R) features functionalities like fingerprint enrolling, image acquisition, feature finding, fingerprint matching, and so on. Without any knowledge about the complicate fingerprinting algorithm, all you need to do is just sending some UART commands, to quickly integrate it into fingerprint verification applications which require small size and high precision.
