Colourful commercial articles bar code and method for setting commercial articles information using the same

Abstract

The invention relates to a color commodity bar code and a method using the bar code to set commodity information. The color commodity bar code comprises a 'bar' symbol and an 'empty' symbol, wherein, the 'bar' symbol and the 'empty' symbol are both color information units. The method using the bar code to set commodity information is that: a 'bar' strip and an 'empty' strip are respectively replaced with an information color bar symbol and an information color empty symbol, wherein, different colors respectively represent '1' or '0' in the binary information, the color change and the width change of the 'bar' symbol and the 'empty' symbol are used to represent the basic information of the commodity consisting of certain characters, numbers and symbols. The invention adds the color information based on the symbol structure of the prior commodity bar code, thereby increasing the information quantity of the symbol; the invention designs the color matching of the bar and the empty according to the technical requirement of optical characteristics of the symbol specified in the national commodity bar code standard, and has good compatibility with the prior scanner.
