Finger Vein Scanner Module - UART Interface

Add finger-vein identification to a compatible access-control project. This enclosed scanner module captures a vein pattern for recognition, providing a biometric input component for a smart lock, cabinet or custom entry interface.

✅ Identify an enrolled user by finger-vein pattern - The module captures internal finger-vein information rather than a surface fingerprint image.

✅ Integrate recognition with a controller - USB and 3.3 V TTL UART interfaces provide connection options for your system.

✅ Fit a compact access point - The enclosed module format suits integration into a lock or control panel.

Build the Recognition Point into the Access Design

A biometric entry project needs both a reader and a controller that decides what to do with the result. This module supplies the recognition stage so the wider system can handle enrolment, access permissions and the lock output.

Position the collection window where a user can present a finger consistently, and follow the module documentation for wiring and software. The package contains the scanner module, not the illustrated motherboard, host or a complete door-lock system.
