Description

Two-dimensional code online collection system

technical field

The utility model relates to the field of the Internet of Things, in particular to a two-dimensional code online collection system.

In the existing technology, a QR code is usually printed on the product packaging, and the relevant information of the product can be obtained by scanning the QR code, such as basic information such as production time, place of origin, company name, etc., and can also include product quality information. Inspection status, composition and other relevant information.

The current two-dimensional code can be roughly divided into two types: "one code for one enterprise" and "one code for one product". "One enterprise, one code" means that each enterprise has its own fixed QR code. Consumers can scan the code to follow the enterprise and learn about enterprise information. "One product, one code" means that each product has a unique QR code. Consumers scan You can view the specific information of this type of product. At the same time, in the process of scanning the QR code of the product, customer consumption information such as the scanning time, scanning location and terminal network of the product’s QR code will also be left on the server of the enterprise, and this information can facilitate the enterprise to do data analysis and understand sales volume, control the distribution channels, and facilitate the unified pricing of products.
