| Abstract: | In this paper,the operating principle,structure and features of Veridicom FPS200 fingerprint sensor are introduced.A design of fingerprint acquisition front-end using serial interface made up of MCU(micro control unit) and FPS200 is also presented, especially the key C51 source code. The system has such features as easy to interface, easy to operate, low power,low cost,and high security. The images obtained by differently parameter-set and interfaced acquisitions are given in the paper. The results show that the images obtained with the proposed system are clearer and less distorted. |
