Abstract
In this paper, we describe a sophisticated scanning system, which is based on an advanced Contact Image Sensor (CIS), used to scan the image and to verify the authenticity of the checks. The entire structure works on the FPGA platform, and the CIS is responsible for sampling the image information served as analog signal that is sent to A/D converter subsequently, aiming to convert analog signal to digital signal. It is important that those digital signal is sent to PC through Cypress non-destructively because those data need to be analyzed by a software on PC to acquire the useful information. This implementation not only clearly scans the image of checks, but it is high precision, simple design, and easy to carry.
