This paper summarizes the research status and development status of automatic fingerprint identification system, the algorithm flow of the fingerprint identification system are introduced, and on the basis of the fingerprint image segmentation algorithm, and fingerprint image thinning algorithm. And finish the fingerprint identification system based on single chip microputer hardware circuit design. ZMF206 fingerprint identification module is applied in this article, the design for fingerprint recognition based on single chip microputer hardware circuit system, fingerprint identification control system to form an independent. The system can realize serial munication between SCM and fingerprint module, by manipulating the independent type keyboard key, to the fingerprint module of DSP chip to send corresponding instructions, to perform input user, add users, authenticate the user, delete to specify user, delete all user, user matching, and other functions, applicable to the need for identification of areas.
