$15
Thin finger vein recognition module Cortex core adaptive USB driver-free UART serial communication liveness detection
Thin Finger Vein Recognition Module
Main control using high-performance Cortex core
Fast recognition, strong stability, low power consumption, easy assembly
Product Features
This product is a finger vein recognition module based on a 32-bit ARM Cortex-M4F processor with a main frequency of up to 192MHz. It supports floating-point operations and DSP instruction sets, and can efficiently run biometric algorithms. The module adopts a light-board separated structure design, which is easy to embed into various terminal devices and improve the integration of the whole machine. The module interface is compatible with the fingerprint recognition industry standard protocol, has good platform adaptability and scalability, and supports rapid development and deployment. It is widely used in smart security equipment such as smart door locks, push-pull or hidden handles, small smart lockers, and access control and attendance systems to help achieve high-precision and high-reliability identity authentication solutions.
- Thin finger vein module, installation thickness is 8.29mm
- High-precision integrated single-board circuit design, no internal connectors, high design reliability
- Based on SOC single-chip system architecture, it has a high-efficiency finger vein algorithm core engine, and the data supports national secret level 2 encryption and EAL4+ security certification qualification
- The module's standby current is less than 5uA, the operating current is less than 19.5mA, and the power-on response is less than 20ms. It is one of the products with outstanding performance in energy efficiency optimization in the industry.
- The venous module adopts a closed design, with no exposed components except the wiring terminals. The waterproof level reaches IP56 and meets the industrial level three-proof standards.
- The module supports USB and UART serial port connection control
- Finger vein module port is compatible with fingerprint industry standard design, seamless application development
- The module algorithm is adaptive and supports both fingerprint protocol and private protocol.
- The near-infrared light source component is separated from the finger vein module by a split design. The near-infrared light source component is installed on the opposite side of the finger vein window, keeping a distance of less than 50mm from the finger vein window and located in the center of it.
Finger vein recognition
Unlike traditional fingerprint modules that collect surface fingerprint images, the finger vein recognition module is based on the principle of near-infrared imaging. It obtains the distribution image of the veins inside the finger by detecting the absorption characteristics of hemoglobin in the blood to near-infrared light. This process effectively avoids the recognition failure caused by damaged, worn or contaminated skin surface texture. After collecting the image, the module will perform multiple processing processes such as image enhancement, filtering, normalization, binarization and feature extraction in sequence to extract the spatial topological feature values of the vein and achieve high-precision live identity recognition. For users whose fingerprints are unclear, worn or missing, finger vein recognition provides a more stable, reliable and secure alternative.

Precautions for use
- After long-term use, thick dust may accumulate on the surface of the collection window, affecting the finger vein recognition effect. The device should be cleaned regularly.
- You can use a cotton swab dipped in a small amount of alcohol to wipe the collection window. If conditions permit, you can use high-concentration liquor. Do not use liquids such as board washing water and electric whitening oil to wipe it.
- The collection window should be protected from impact by sharp objects.
- Avoid using in rain, direct sunlight, or in strong magnetic or electrical environments.
- It is strictly forbidden to have metal objects or conductive materials contact or approach the surface of the collection window to avoid physical damage
