Finger vein recognition module
Biometric Finger Vein Smart Door Lock Safe Recognition Module
Introduction:
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.
Features:
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
Application:
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
