Specific bar code and forming method thereof

Abstract

The invention discloses a specific bar code and a forming method of the specific bar code. The method includes the steps that at least one same one-dimensional bar code and colorful information and / or gray information are formed in a printing stock randomly, wherein the colorful information and / or gray information are / is overlapped on the printing stock respectively and correspond / corresponds to the regions of the one-dimensional bar codes; the colorful information and the grey information contain data information after being recognized; the one-dimensional bar code and the colorful information and / or gray information are recognized respectively when collection is conducted through a portable electronic device provided with the image capture function, and the misjudgment rate for recognizing the one-dimensional bar code is lower than 40%. According to the specific bar code and the forming method of the specific bar code, colorful backgrounds are overlapped on the one-dimensional bar codes, the coding capacity is broadened on the basis of keeping characteristics of the one-dimensional bar codes, one piece can be recognized by one code, and added value is brought out for business men by applying traceability and other applications of the mode that one piece can be recognized by one code.

Description

[0001] This application claims the national priority of the Chinese patent application with application number (CN201410193210.7). The entire content of the Chinese patent application CN201410193210.7 is incorporated herein by reference. technical field [0002] The present invention relates to barcodes, and more particularly, to certain barcodes and methods of forming them. Background technique [0003] At present, one-dimensional barcodes and two-dimensional barcodes are widely used in various fields as identification marks in the process of item circulation and warehousing. A large number of traditional fields still use one-dimensional barcodes, such as cigarettes, food and various daily necessities. [0004] Barcode technology was developed to eliminate the "bottleneck" problem of data entry during the development of computer applications. It can be said to be the "oldest" automatic identification technology. In 1973, the Uniform Code Committee of the United States sele...

Problems solved by technology

The application of one-dimensional barcode can improve the speed of information entry and reduce the error rate, but one-dimensional barcode also has some shortcomings: the data capacity is small: about 30 characters; it can only contain letters and numbers; the barcode size is relatively large ( Inefficient use of space); barcodes cannot be read if damaged

However, due to the relationship between the coding capacity of the one-dimensional barcode, each code of the one-dimensional barcode represents a commodity, that is, one code per product, which cannot identify the uniqueness of a single commodity
