Automated fingerprint identification system has an increasingly important role in modern times. This paper presents the steps of the automated fingerprint identification system and presents an application for fingerprint identification and system's equal error rate evaluation. The algorithm for fingerprint image enhancement is a key element of the system. A fingerprint image can be damaged, damp, too dry, worn, scratched, etc. Therefore it is necessary to enhance the image to the point where the user can obtain a clearly defined structure of ridges and valleys and consequently also correctly determined features.
