ABSTRACT:
A reader for machine reading a symbol printed on a document. The light source shines light through a form at the location of a symbol printed on the form, and onto an array of light sensitive cells. This casts an image of light and shadow on the array. The array generates a signal in response to that image, which signal is processed to determine the information carried by the symbol. A writer such as a computer printer may also write to the document, and the information written to the document can be stored in a computer in conjunction with the information (such as an identification number) read from the symbol. Also, the method of encoding an identification number in a symbol, and decode it with the reader.
