Description
Product Description
The R307S is a high-performance, all-in-one optical fingerprint verification module designed for seamless integration into security and identification systems. It combines a high-precision optical path, a specialized image processing chip, and a powerful DSP processor into a single, compact housing.
This module is a complete biometric solution: it handles fingerprint image collection, feature extraction, template generation, storage, and matching (1:1 or 1:N) internally. Whether you are building a smart door lock for a home or a complex time-attendance system for a business, the R307S offers a reliable, “plug-and-play” experience with low power consumption and high-speed recognition.
Key Features
- Integrated Design: All biometric processing is done on-board; no external libraries or heavy processing power required from your host controller.
- Touch Trigger Technology: Features a dedicated touch-sensing signal output that allows the module to remain in sleep mode until a finger is detected, significantly extending battery life.
- High Recognition Accuracy: Advanced optical imaging ensures a low False Acceptance Rate (FAR) and False Rejection Rate (FRR), even with dry or slightly aged fingers.
- Dual-Interface Communication: Supports both UART (TTL) for microcontrollers and USB 2.0 for direct PC integration.
- Adjustable Security Levels: Users can configure the security threshold (Levels 1–5) to balance speed and strictness based on the application.
- Self-Learning Logic: The algorithm updates the stored template slightly with each successful scan to account for minor changes in finger orientation or condition.
