•Perfect functions Fingerprint Sensor, the fingerprint module can complete the fingerprint collection,  fingerprint registration, fingerprint contrasting and fingerprint search functions independently.


•Good security, the fingerprint module adapts to reflective sensors detecting technology, and has live fingerprint detection function, which eliminate the error of forged fingerprints fundamentally, such as dead fingers and copied fingerprints.


•Strong adaptability and high performance algorithms, it has strong ability to different categories, such as dry fingers, wet fingers, and light texture fingers all have high literacy rate and good correction, fault-tolerant performances.


•Strong electrostatic resistance ability, which is good applicable to the region where the environment is dried and easy electrostatic.


•Simple application development, developers don’t need to have fingerprint expertise, they can accord to provided command words, develop their own fingerprint application product.

•Fingerprint Sensor has Thin volume,  and the sensor’s thickness is very small,  which can be embedded in a variety of products.
