Abstract

The invention relates to a method for transmitting information based on two-dimension bar code, wherein said information has type characters; and the inventive method comprises that (1) building the type list between different type character and serial number; (2) decomposing the exchange original information into information blocks, to be separated by separators, while each information block is arranged by their sequence in the original information; (3) numbering the different type characters, and arranging them by the sequence of information blocks in original information, to obtain the character information; (4) forming two-dimension bar code from character information and information blocks via the code method of two-dimension bar code; (5), reading out two-dimension bar code, to obtain the character information and information blocks; (6) reducing the character information into type information, while they are one-to-one relative. The invention can keep original character information, and effectively treat the content after exchange, while the two-dimension bar code has minimum size in same resolution.

Description

(1) Technical field

[0001] The invention relates to a method for transmitting information through a two-dimensional barcode and its dedicated encoding device and decoding device. (2) Background technology

[0002] If it is necessary to form a two-dimensional barcode for the information on the business card, write all the text information on the business card, and generate a two-dimensional barcode through the two-dimensional barcode encoder. For information with classification attributes such as business cards, if all the information is directly converted into a two-dimensional barcode, the disadvantages are: (1), the amount of information carried is large, and the size of the two-dimensional barcode is larger at the same resolution; (2) After the information is exchanged, attribute information and content information cannot be distinguished, and subsequent efficient processing of the content information cannot be performed. (3) Contents of the invention

[0003] In order...
