With a compact form factor, high‑security fingerprint algorithm and proven capacitive sensing technology, the ID1020B fingerprint reader module is an ideal choice for manufacturers seeking a reliable fingerprint scanner module for mass production and long‑term deployment.
The ID1020B is a compact fingerprint reader module that integrates a high‑resolution capacitive fingerprint sensor with a dedicated ARM processing core and a self‑learning fingerprint algorithm. It is designed for fast, accurate and secure fingerprint identification in embedded and commercial devices.
This module uses a capacitive fingerprint sensor. Compared with optical sensors, capacitive technology provides better image clarity, stronger anti‑spoofing performance, and more stable operation under dry, wet or worn finger conditions.
Yes. The built‑in IDWDfinger algorithm supports adaptive learning. When a user’s fingerprint slightly changes due to aging, skin condition or long‑term use, the module can automatically update fingerprint features during successful verification, improving long‑term recognition accuracy.
The fingerprint scanner module supports both 1:1 and 1:N matching modes. This makes it suitable for applications such as personal authentication, access control systems, and multi‑user identification devices.
Typical comparison time is less than 0.2 seconds for 1:1 matching, and less than 0.5 seconds for 1:N matching with up to 170 fingerprint templates. This ensures a smooth user experience even in high‑traffic scenarios.
Depending on the configuration, the fingerprint reader module can store 170, 500 or up to 1000 fingerprint templates. Each fingerprint template occupies 448 bytes of internal memory.
The module supports UART (3.3V TTL level) and USB communication. Multiple baud rates are available, with 115200 bps as the factory default, allowing easy integration with microcontrollers, embedded boards and host systems.
This fingerprint sensor module supports development under Windows, Android, Linux and various embedded operating systems. A complete SDK and communication protocol documentation are provided for fast integration.
Yes. The module offers adjustable security levels from Level 1 to Level 5. At the default Level 3, the false acceptance rate (FAR) is below 0.001%, making it suitable for electronic door locks, access control and POS terminals.
Common applications include electronic door locks, attendance systems, access control panels, POS machines, smart terminals and IoT devices that require reliable biometric authentication.
Yes. We provide SDKs, command documentation and integration guidance. Our engineering team can also assist with evaluation, firmware configuration and production deployment if required.
