Problems solved by technology

The "three-dimensional commodity barcode system" is also shortcoming: in the current domestic and foreign supermarkets, the most widely used one-dimensional commodity barcode laser scanner cannot recognize the variable data contained in the two-dimensional code of its commodity serial number.
Since it cannot capture the QR code image, it is also impossible to realize the function of scanning and recognizing the QR code by upgrading the software, and it is impossible to collect anti-counterfeiting, logistics, lottery, traceability, production date and other variables by the way when scanning the code at the cash register. data

Embodiment 1

[0081] figure 1 , Figure 15 As shown, the standard size of the current commodity barcode, that is, the one-dimensional barcode (3) is 37.29mm×26.26mm, and the magnification ratio is 0.9-2.0. When the printing area allows, you can choose a one-dimensional barcode ⑶ with a ratio of 1.0 or more.

[0082] In order to make the commodity barcode described in the national standard GB12904-2003, that is, a one-dimensional barcode shared by tens of thousands of products (3)—fixed information, it can also imply logistics codes, lottery codes, traceability codes, etc. that are unique, Variable data unique to each product (5)——variable information. like figure 1 As shown, some breakpoints (4) representing variable data (5) can be printed on some bars (1) or bar spaces (2) in the one-dimensional barcode (3) according to some custom rules.

[0083] like figure 1 As shown, the bar (1) of the one-dimensional barcode (3) is divided into 14 equal parts along the height direction, arrang...

Embodiment 2

[0092] like figure 2 As shown, all the breakpoints (4) are printed in the lower area of ​​the one-dimensional barcode (3), accounting for less than 67% of the area of ​​the one-dimensional barcode (3). The shortcoming of designing like this is: more than 67% of the one-dimensional barcode (3) area has been damaged, which is unfavorable for reducing the misjudgment rate of one-dimensional barcode (3) identification.

[0093] like figure 2 As shown, some of the bars (1) in the one-dimensional barcode (3) look thicker and some seem thinner. The thick bar ⑴ is actually formed by multiple thin bars ⑴ together, and a single thin bar ⑴ is a standard bar ⑴ module. When a narrow breakpoint (4) is printed on the thick bar (1), the breakpoint (4) looks like a gap.

[0094] The remaining steps of this embodiment are the same as those in Embodiment 1.

Embodiment 3

[0096] like image 3 As shown, all breakpoints (4) are all printed on a very narrow area on the one-dimensional barcode (3), accounting for less than 15% of the area of ​​the one-dimensional barcode (3). The advantage of designing like this is: more than 85% of the one-dimensional barcode (3) area is intact, helps to reduce the misjudgment rate of one-dimensional barcode (3) recognition. The disadvantage of this design is: the variable data (5) contained in the breakpoint (4) is slow and difficult to identify.

[0097] In this embodiment image 3 In the above, the bars ⑴ and bar space ⑵ of the one-dimensional barcode ⑶ are divided into 14 equal parts along the height direction, arranged from bottom to top, the 1st-2nd equal parts are used as the start symbol, and the 13th-14th equal parts are used as the end character, the 3rd and 4th equal parts represent the 0th position and the 1st position respectively.

[0098] like image 3 As shown, all 30 bars (1) and bars (2) of t...

Abstract

The invention provides a commodity bar code with hidden variable data and a formation method of the commodity bar code. The bar code comprises a one dimensional bar code which is printed on a bearing object and formed by bars, vacancies and arrays thereof. Breaking points are printed on the bars or the vacancies. After positions or / and quantity or / and lengths of the breaking points are identified by a breaking point decoding software, variable data including commodity tracing coding can be identified. According to the invention, color digital printing is avoided; the commodity bar code and the formation method are suitable for monochromatic printing; investment of devices can be reduced; production speed can be improved; manufacturing cost can be reduced; and there is no need to replace current laser scanner hardware.

Description

technical field [0001] The invention belongs to the technical field of one-dimensional commodity barcodes, and in particular relates to a commodity barcode with implicit variable data and a forming method thereof. Background technique [0002] Commodity barcodes are barcodes specified by the International Article Numbering Association (EAN) and the Uniform Code Committee (UCC) to identify commodity codes, including EAN commodity barcodes (EAN-13, EAN-8) and UPC commodity barcodes (UCC-A , UCC-E) and other commonly used one-dimensional commodity barcodes. The commodity bar code described in the national standard GB12904-2003 of the People's Republic of China is a one-dimensional bar code composed of multiple bars (modules) and multiple bars (modules) arranged in parallel. [0003] Current 1D barcodes (such as Figure 15 shown) is a mark composed of a set of regularly arranged bars, spaces and corresponding characters. The reflectivity of bars to light is low, and the reflect...
