R305 overview
This is R305 Fingerprint processing includes two processes: fingerprint registration process and fingerprint matching process (fingerprint matching which is divided into fingerprint matching (1: 1) and fingerprint search (1: N) in two ways]. When the fingerprint is registered, entry twice for each fingerprint, and processing the image, a composite template is stored in the module. Fingerprint matching, through the fingerprint sensor, enters the fingerprint image and processing, and then matches the comparison with the module fingerprint template (if it is matched by a template specified in the module, known as fingerprint matching, that is 1: 1 mode. It is called fingerprint search mode (1: N mode) if it is matched with multiple templates. The module gives the result of checking (pass or fail).
