Product Description


Finger vein recognition module

Biometric Finger Vein Smart Door Lock Safe Recognition Module




The Dot touch pattern finger vein recognition module SJ-338 enables finger vein recognition with a single touch.

This module consists of high-sensitivity infrared image sensor, low-power high-performance DSP processor, flash memory, etc. It has the advantages of thin thickness, durability, super anti-static, low power consumption and high security and other advantage.




1.Finger touch placement, national patent protection

2.Light and thin, with a maximum thickness of 21mm

3.Low power consumption, standby power consumption below 5μA

4.ESD air discharge 15KV, contact discharge 10KV

5.1:1 or 1:N authentication method

6.Fast authentication, 1:100 less than 1 second

7.Integrated module design, the processing, matching and storage of the veins are all completed in the module.

8.Universal UART interface for secondary development




This module is widely used in applications such as authorization, management, and security. It can be used to replace RFID cards, passwords, fingerprints, hardware switches, etc. It is especially suitable for high security requirements, low power consumption, and small volume embedded design applications. Application areas include but are not limited to the following occasions:


1.Smart door locks, safes, filing cabinets, etc.

2.Management software, licensing and other security management areas
