Product Features

This is a high-precision integrated finger vein module. The module is equipped with a 32-bit ARM Cortex-M4F core, with an operating frequency of up to 144MHz, and supports floating-point arithmetic operations and DSP instruction sets. The module adopts a fully enclosed design, with no other exposed components except the wiring terminals, and a waterproof rating of IP56. The module port supports compatible fingerprint industry standard design and is adaptive, allowing user applications and development to connect seamlessly. It is suitable for applications in straight-plate smart locks, sliding cover smart locks, embedded locks, glass door locks, apartment rental locks, various small smart cabinets, simple access control and other products.

Finger vein recognition

Different from the fingerprint module that reads fingerprint images, the finger vein module uses the principle of infrared imaging to collect the distribution image of the veins inside the finger and obtain the characteristic value for liveness recognition. For users whose fingerprints are unclear or missing, the finger vein module is a good choice.

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
