SM-621B Fingerprint Module
Independent intellectual property rights
SM-621B module uses optical fingerprint sensor. Its hardware includes low power ARM9 microprocessor and FLASH. Its functions include: fingerprint image process, template extraction, template match, fingerprint search and template store.

Independent intellectual property rights

All the technologies include optical fingerprint reader, module hardware and fingerprint algorithm are developed by MIAXIS.

 

Excellent algorithm performance

 

Strong fingerprint adaptability

During reading the fingerprint image, it uses the adaptive parameter adjustment mechanism. The image quality is good enough for dry or wet finger. Support 360 degree searching.

 

Price is better

The optical parts are self developed for the reason of cost saving.

 

Easy to use and convenient expansion

 

Low power

Provide sleep and wakeup function.

 

Flexible set security level

 

Integrated design

Integrated design is flexible for installation.

 

Living fingerprint capture

Add the sensor for living fingerprint to prevent fake fingerprint. The living capture function can be switched on and off.
