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.

Abstract: A dispenser produces negotiable money orders, traveler's checks, and the like at remote locations and prints the check amount on the check while also printing summary data of a day's activities on a blank check form, eliminating the need for a separate printer and paper supply. The dispenser prints the check amount using print icons that form a part of each character in the check amount, but are not as large as a complete character or as small as a dot print element. The check forms are connected together by perforation ties, and the dispenser feeds the forms to the printer such that the force with which the dispenser holds the forms is greater than the force needed to tear apart the forms, thus reducing the risk of unauthorized pulling of blank forms from the dispenser.
