- High-precision integrated all-in-one design with no redundant internal wiring, high design reliability
- Based on SOC microcontroller system architecture with a high-performance finger vein algorithm engine, supports EAL4+ security certification
- The standby current is less than 5uA, the working current is less than 19.5mA, and the power-up response time is less than 20ms, making it one of the products with excellent energy efficiency optimization in the industry
- Fully enclosed structure with no exposed components except for the wiring connectors. Conforms to industrial-grade Triple-Proof standard, and the waterproof level reaches IP56
- Supports USB and UART serial communication
- The module interface is compatible with the fingerprint industry standard, more convenient for integration and development
- The module algorithm features adaptability, and supports both fingerprint protocol and private protocol
- Adopts a separated design, the near-infrared (NIR) light source is physically separated from the finger vein module and mounted opposite the finger vein window, centered and within a 50mm range
Different from the traditional fingerprint module to capture surface fingerprint images, the finger vein recognition module utilizes near-infrared imaging technology to detect the absorption characteristics of hemoglobin in the blood under near-infrared light and obtain the vein distribution image within the finger. This method effectively avoids recognition failures caused by skin damage, abrasion, or surface contamination.
After collecting images, the module will perform a series of processing steps such as image enhancement, filtering, normalization, binarization, and feature extraction, to extract the spatial topological features of the vein pattern, enabling high-precision liveness identification. For users with unclear, worn, or missing fingerprints, finger vein recognition offers a more stable, reliable, and secure biometric alternative.

- After long-term use, dust may accumulate on the surface of the collection window and affect finger vein recognition performance. It is recommended to clean the device regularly.
- You can use a cotton swab dipped in a small amount of alcohol to wipe the collection window. If alcohol is not available, high-proof liquor can be used as an alternative. Do not use cleaning agents like PCB board cleaners or electric contact cleaners.
- Avoid impact from sharp objects on the collection window.
- Avoid using the device in rain, direct sunlight, and strong magnetic or high electrical fields.
- Keep metal objects and conductive materials away from the surface of the collection window to prevent physical damage.

Gently place the finger parallel to the collection window and touch both sensing points simultaneously
