The ID1042YT optical fingerprint sensor is a high-performance biometric module designed for secure identity authentication. Built with advanced optical imaging technology and powered by the ID821 high-speed processor, it delivers sharp fingerprint images, fast recognition, and stable performance in both dry and moist conditions.
With a simple touch, the sensor captures and processes fingerprint data in seconds. Integrated with the latest IDFinger V6.0 algorithm, the module supports fingerprint enrolment, feature extraction, template generation, storage, matching and search — all within a compact and easy-to-integrate design.
