 * Input/Output || Input || Input || Input ||
 * What does it do? || Captures human marked data from hard copy documents, or written files. || Decodes, and makes sense of the data collected from OMR, turning it into meaningful information || Used to verify specific documents to confirm they are legitimate. ||
 * How does it work? || There are two ways. First way is a strong beam of light is shone onto the paper, and the reflections and contrast in terms of the paper and writing determines the markings. Second way is to shine a strong light through the paper, where transoptic paper is underneath, to capture and calculate any changes in the light that passes through the paper. || A software processes the complicated markings from the OMR, and then cross references(as well as could lay a digital overlay) over the markings with a template to verify information is valid, or make sense of the information, presenting it in the desired manner. || Special documents are printed with special fonts, and ink that usually have some form of magnetic substance in it, primarily iron oxide. The main fonts used are E-13B and CMC-7. A computer is used to decode the cheques as firstly the document is mildly magnetised. After being magnetised it is passed under a special machine called a MICR read head. As its under each character emits a specific wavelength that is verified by a computer to confirm the document to be legitimate. ||
