Fingerprint Reader Sensor

With this fingerprint reader sensor, you can perform fingerprint reading operations with high sensitivity and security. It has many features such as small volume, low power consumption, simple interface, high reliability, fast recognition and good compatibility for dry or wet fingers, fast detection of fingerprint.

Working Principle

The feature extracted from the obtained fingerprint image by the fingerprint algorithm represents the information of the fingerprint. Fingerprint storage, comparison and search are done by processing fingerprint features.

Fingerprint processing consists of two processes: fingerprint entry process and fingerprint matching process. [fingerprint matching is divided into fingerprint comparison (1:1) and fingerprint search (1:N)].

When the fingerprint is registered, each fingerprint is entered twice, and the recorded image is processed twice and composited. the template is stored in the module.

When the fingerprint matches, the fingerprint image is entered and the fingerprint image is verified and processed and then matches the fingerprint template in the module. If the template is matched with a template specified in the module, it is called fingerprint comparison method, i.e. 1:1. Mode; If it matches more than one pattern, fingerprint search mode, i.e. 1:N mode), the module returns the matching result (pass or fail).
