摘要: A system for verifying an object of interest, includes a grayscale one-dimensional bar pattern coupled to the object, illumination and imaging using device reading producing image, translating image into sequence widths transition directions representing detected code, comparing code with predetermined indicating one acceptance or rejection based on comparison code.
