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 processed the image, a composite template is stored in the module. Fingerprint matching, through the fingerprint sensor, entry the fingerprint image and processing, and then matching comparison with the module fingerprint template (if it is matched a template specified in the module, known as fingerprint matching, that is 1: 1 mode. If it is matched with multiple templates, it is called fingerprint search mode (1: N mode). The module gives the result of matching (pass or fail).
