Features

This product is a high-precision integrated finger vein module, equipped with a 32-bit ARM Cortex-M4F core, the operating frequency is up to 144MHz. Supports floating-point algorithm calculation and DSP instruction set. The module adopts a fully enclosed design, with no other exposed components except for a wiring connector, achieving a waterproof rating of IP56.

The module interface is compatible with the fingerprint industry standard and features USB port adaptability, more convenience for integration and development. It is suitable for applications such as slim handle smart locks, sliding smart locks, embedded locks, glass door locks, apartment and rental locks, various small smart cabinets, and basic access control systems, etc.

  • Slim handle smart lock finger vein module with a mounting thickness of 13.5mm
  • High-precision integrated all-in-one design, only reserved one connector for host devices, high design reliability
  • Based on SOC microcontroller system architecture, with high computing efficiency of the finger vein algorithm kernel engine
  • The standby power consumption is less than 2uA, working power consumption is less than 43.0mA, and the power-up response time is less than 20ms, making it one of the products with excellent energy efficiency optimization in the industry
  • Adopts a fully enclosed design, without any exposed components except for a wiring connector, and the waterproof level reaches IP56. Conforms to industrial-grade Triple-Proof standard, and the waterproof level of the exposed part is as high as IP66
  • The module interface is compatible with the fingerprint industry standard, more convenience for integration and development
  • The module algorithm features adaptability, and supports both fingerprint protocol and private protocol
  • Strong anti-interference capability, supports use in environments below 30000LUX

Finger vein recognition

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

Precautions for Use

  • After long-term use, dust may accumulate on the surface of the collection window and affect the effect of finger vein recognition, so regular cleaning of the device is recommended.
  • You can use a cotton swab dipped in a small amount of alcohol to wipe the collection window. If alcohol is unavailable, high-proof liquor can be used as an alternative. Avoid using cleaning agents like PCB board cleaners or electric contact cleaners.
  • The collection window should be protected from the impact of sharp objects.
  • Avoid using the device in rain, direct sunlight, and strong magnetic or high electrical fields.
  • Do not allow metal or conductive materials to touch or come close to the surface of the capture window to prevent physical damage.
