Product Overview
Bring professional-grade biometrics to your DIY projects with the ID1028S Arduino fingerprint module. Unlike older optical sensors, the ID1028S utilizes a highly sensitive capacitive fingerprint sensor combined with a powerful Cortex M4 Core processor (ID809). This ensures rapid recognition, anti-spoofing security, and reliable performance even in varying environmental conditions.
Designed for versatility, this fingerprint sensor module for Arduino is compact, easy to integrate via UART, and supports a massive library of up to 3,000 fingerprints. Whether you are developing a smart door lock, a secure office cabinet, or an attendance system, the ID1028S offers the perfect balance of size, speed, and security.

Key Features & Benefits
Why choose the ID1028S? It solves the common "slow match" issue found in cheaper modules by using the new-generation IDFinger6.0 algorithm, achieving a 1:N comparison speed of less than 0.6 seconds.
Advanced Capacitive Technology: Offers superior image quality (508dpi) and security compared to traditional optical scanners.
Cross-Platform Compatibility: Works seamlessly as an Arduino fingerprint reader, but also supports Windows, Android, and other embedded operating systems.
High Capacity & Speed: Stores up to 3,000 unique templates with a lightning-fast processing speed.
Easy Developer Integration: Features a standard UART (3.3V-TTL) interface, making it plug-and-play for MCU development.
Robust Durability: Operates effectively in temperatures ranging from -20°C to 55°C.
