Features
- Thin-type module with 8.29mm thickness
- Integrated all-in-one design with high reliability
- Based on SoC microcontroller with high-performance vein algorithm, EAL4+ certified
- Standby current < 5uA, working current < 19.5mA, power-up response < 20ms
- Fully enclosed, IP56 waterproof (excluding connectors and NIR light)
- Supports USB and UART (3.3V TTL, 57600bps)
- Compatible with standard fingerprint protocol and private protocol
- Separated NIR light source mounted opposite the vein window (within 50mm)
Technology
Uses near-infrared imaging to detect blood absorption and extract finger vein patterns. Offers improved reliability over fingerprint modules by avoiding issues with skin surface conditions.
