Abstract 1. Field of the Invention A fingerprint certifying device for an effective data capture state when a fingerprint is certified, including: a storage unit for storing a registered fingerprint image; a collating unit for collating a collating fingerprint image inputted to a fingerprint sensor with the registered fingerprint image divided into a predetermined number of blocks; a counter for counting up the number of effective blocks in which the registered fingerprint image of the predetermined number of blocks is coincident with the collating fingerprint image; and a display unit for displaying the value corresponding to a ratio of the count value of effective data to a predetermined block number.
