Abstract

A bar code for encoding information in machine-readable form is provided. The bar code comprises a character string including a plurality of characters disposed side-by-side along a longitudinal code axis. Each character is formed by a sequence of code bars and intervening code spaces, the code bars being parallel to one another and to a line defining a bar axis which intersects the code axis. Each character has a definition in accordance with a predefined standard. The definition for each character includes a bar/space pattern associated with the character setting forth the respective widths of the code bars and code spaces making up the character in terms of integer multiples of a minimum unit width. The definition for each character also includes at least one encoded alphanumeric value associated with the character. The definition for each character further included an integer checksum value associated with the character. The plurality of characters in the character string includes, sequentially, one start character, at least one message character, one check character and a stop character. The bar axis forms a slant angle with a line perpendicular to the longitudinal code axis, and the slant angle has a value greater than about 1 degree.
