SM-621 series optical fingerprint verification module is a new released product by Miaxis Biometrics Co., Ltd for the industry market demand of access control system, door lock, time & attendance, safety box or safety cabinet etc. Consisting of high function DSP, large capacity FLASH and color CMOS, etc, it can conduct fingerprint enrollment, image processing, templates storage, fingerprint matching and fingerprint searching.


Strong Functions: independently conduct the functions of fingerprint enrollment, image processing, minutiae extraction, templates storage, fingerprint verification (1:1) or fingerprint searching (1:N) under the command of HOST( PC or MCU).

Easy Develop: Module has rich commands, equivalent to fingerprint function base. Developers do not need to know the fingerprint verification professional know-how and can develop strong function fingerprint verification application system according to control instructions of SM-621.

Rich Interface: Power supply: DC 3.6-7V. Serial communication interface: standard UART protocol, two electricity levels, baud rate alternative.

Low consumption Design: Provide user sleep function control interface, suitable for low consumption condition.

Strong adaptability: Algorithm function of SM-621 module is excellent. It is designed according to optical imaging theory and has good function of proof and fault-tolerant for poor quality fingerprints.

Wider suitable people application scope. SM-621 module adopts self-adaptive parameters adjusting mechanism during the fingerprint image reading, thus it makes good imaging quality for dry or wet fingers.

Adjustable safety level: Users can set the different safety level by themselves according to different application condition.

Suitable for different application condition: Easily set the SM-621 module on different work mode according to application system requirement. Select module with different fingerprint templates capacity according to the requirement of users’ number on different conditions.
