A kind of combination bar code
Technical field
The utility model relates to bar code field, particularly relates to a kind of combination bar code strengthening the information content and express.
Background technology
The Antiforge bar code technology of more employing Quick Response Code or one-dimension code on the market, but bar code is just in a direction (being generally horizontal direction) expressing information, does not then express any information in the vertical direction.Although the information that Quick Response Code stores is more more, Quick Response Code, owing to being a kind of current techique, is wanted to increase information further or transmit private information to be then difficult to realize.
Utility model content
The purpose of this utility model is the deficiency for prior art, provides a kind of combination one-dimension code and Quick Response Code, strengthens the combination bar code that the information content is expressed.
To achieve these goals, the technical scheme that the utility model provides is: provide a kind of combination bar code, comprise basic unit and cover layer, two-dimensional bar code is provided with in basic unit, be provided with one or more bar code on the cover layer, described cover layer is transparent membrane, cover layer is affixed in basic unit and bar code and two-dimensional bar code are combined, wherein, bar code is positioned at two-dimensional bar code surrounding or two-dimensional bar code non-information scanning area, described bar code and two-dimensional bar code is scanned according to setting order, bar code and two-dimensional barcode information carry out principle combinations, express for strengthening the information content.
Can by basic unit and tectal location swap, basic unit is provided with one or more bar code, is provided with two-dimensional bar on the cover layer.
The beneficial effect of the utility model combination bar code is, bar code is combined with two-dimensional bar code, described bar code and two-dimensional bar code is scanned according to setting order, by bar code and two-dimensional barcode information content permutation and combination, thus make effable content obtain self-defined and strengthen, the information content of transmission of information and privacy are strengthened.
By following description also by reference to the accompanying drawings, the utility model will become more clear, and these accompanying drawings are for explaining embodiment of the present utility model.
Accompanying drawing explanation
Figure 1 shows that the structural representation of the utility model combination bar code.
Figure 2 shows that the utility model combination bar code tectum structure schematic diagram.
Figure 3 shows that the utility model combination bar code base layer structure schematic diagram.
Detailed description of the invention
With reference now to accompanying drawing, describe embodiment of the present utility model, element numbers similar in accompanying drawing represents similar element.As mentioned above, shown in figure 1-3, the utility model provides a kind of combination bar code 100, comprise basic unit 110 and cover layer 120, two-dimensional bar code 111 is provided with in basic unit 110, cover layer 120 is provided with one or more bar code 121, described cover layer 120 is transparent membrane, cover layer 120 is affixed in basic unit 110 and bar code 121 and two-dimensional bar code 111 are combined, wherein, bar code 121 is positioned at two-dimensional bar code 111 surrounding or two-dimensional bar code non-information scanning area, described bar code and two-dimensional bar code is scanned according to setting order, bar code and two-dimensional barcode information carry out principle combinations, express for strengthening the information content, for Quick Response Code and one-dimension code information sum.
As object lesson, such as first scanning two-dimension bar code, then scan bar code, the bar code after scanning finally can form a character, and the final character formed obtains product information in order to coupling, specific rules rule singlely in order in Quick Response Code can insert the one-dimension code of taking out, if one-dimension code is 123456, Quick Response Code is ABC98FG008, then a character string of final composition is: A1B2C39485F6G008, product code corresponding to match query is got final product according to this character string, this rule can play good data antifalsification, in addition the odd bits that it is also conceivable to bar code is corresponding with two-dimensional bar code odd number, even bit is corresponding with even bit, thus the multiple combination modes such as the character of composition one containing two characters, so data separation that can be represented with general bar code by combination is come, there is stronger operability, form distinctive bar code product.
Above disclosedly be only preferred embodiment of the present utility model, certainly can not limit the interest field of the utility model with this, therefore according to the equivalent variations that the utility model claim is done, still belong to the scope that the utility model is contained.
