Description

This module utilizes near-infrared (NIR) imaging technology to capture the unique vein patterns beneath a user’s finger, offering a highly secure and hygienic biometric authentication method. The separated NIR light source design enhances image quality and simplifies optical integration into various terminal enclosures.

Based on a SOC architecture, it combines a high-performance microprocessor with a dedicated biometric algorithm engine, supporting both industry-standard fingerprint protocols and private communication protocols for flexible system development. Its fully enclosed, IP56-rated construction ensures reliable operation in demanding environments.

Key Features

  • High-Performance SOC Core: 32-bit ARM Cortex-M4F microprocessor operating at 192MHz, supporting floating-point and DSP instructions for efficient algorithm execution.
  • EAL4+ Certified Security: Implements a high-security finger vein recognition algorithm certified to EAL4+ standards for robust identity verification.
  • Optimized Power Management: Features ultra-low standby current (<5μA) and efficient active operation (<19.5mA), ideal for battery-powered applications.
  • Durable Industrial Design: Fully enclosed ABS+PC housing with an IP56 rating for protection against dust and water jets.
  • Dual Communication Interfaces: Supports both USB and UART serial communication for easy integration with host controllers and PCs.
  • Protocol Compatibility: Interface is compatible with industry-standard fingerprint recognition protocols, ensuring broad platform adaptability.
  • Separated NIR Illumination: The NIR light source is physically separated from the imaging sensor, allowing for optimized optical alignment and integration.
  • User Database: Supports a capacity of 100 user IDs for personalization in access control and attendance systems.

Applications

  • Smart Door Locks & Handles: Integrated into ultra-thin push-pull or concealed door handles for keyless, hygienic entry.
  • Access Control & Time Attendance Systems: Provides high-security, contactless user authentication for corporate and institutional entry points.
  • Secure Storage & Cabinets: Enables biometric locking for compact smart storage, medical cabinets, or personal safes.
  • Financial & Vending Terminals: Used in ATMs, self-service kiosks, or high-value vending machines for user identity verification.
  • IoT Security Devices: Integrates into portable or fixed IoT devices requiring a high level of user identity assurance.

Frequently Asked Questions

What is the operating voltage and how should I power this module?

The module requires a stable 3.3V DC power supply. It is critical to use a clean, regulated power source to ensure stable operation of the Cortex-M4F core and the sensitive NIR imaging components. The included 3.3V adapter board can be used for convenient connection.

What communication protocols does this module support?

It supports both USB (Virtual COM Port) and UART serial communication (TTL level). The UART interface uses standard baud rates and is compatible with most microcontrollers. The module's command protocol is compatible with common fingerprint sensor standards, simplifying integration.

What is the meaning of the IP56 rating for this sensor?

The IP56 rating indicates the module is fully protected against dust ingress (IP5X) and can withstand powerful water jets from any direction (IPX6). This makes it suitable for use in environments where it may be exposed to dust, rain, or cleaning sprays, such as on exterior door handles.

How many user profiles can the module store?

The module has an onboard database capacity for 100 unique user IDs (finger vein templates). Enrollment and management of these profiles are performed via the serial command set sent over the UART or USB interface from your host controller.

How does the separated NIR light source work?

The near-infrared (NIR) LED light source is a separate physical component from the main imaging module. It must be mounted opposite the sensor's vein imaging window, centered and within a 50mm range. This design allows for flexible optical integration to optimize illumination and image contrast for vein pattern capture.
