Embodiment Construction
[0016] The invention relates to a layering and verification method based on different two-dimensional codes. The method is based on the layering setting of no less than two two-dimensional codes, and is realized by means of a two-dimensional code reading terminal and a two-dimensional code reading terminal. Realized by the server of information interaction, the black dot matrix that exists in the same position on all two-dimensional codes is set as the code source and set on the product, and the remaining black dot matrix on each two-dimensional code is set as the code branch and stored in the server Among them, different types of people get different codes, and after combining with the code source to scan the code, they get different QR code content. Based on the above principles, different types of code-scanning visitors are treated differently.
[0017] In a specific example, beer is a relatively common consumer product. Local sales of beer in this region can occupy a certai...
