Transducer for fingerprints and apparatus for analyzing fingerprints

摘要: The fingerprint transducer contains a sensing member having surface for receiving fingerprint. is made of material which has transition or softening temperature that higher than ambient and close to the finger. Particularly, chosen such will start melt on when finger pressed against surface. relief random roughness. In other words, variations in elevation do not show specific pattern. method analyzing fingerprints comprises steps generating space member, by pressing thereto, optically reading from
