Bar code technology is an automatic identification technology developed in computer application, which is widely used in business, postal service, book management, warehousing, industrial production process control, transportation, packaging, distribution and other fields. It first appeared in the 1940s, and it is "composed of a set of regularly arranged bars, spaces and their corresponding characters, which are used to express certain information".
Using bar code scanning is the general trend of future market circulation. In order to make goods circulate freely and widely in the world, enterprises must abide by the relevant provisions of commodity bar codes whether designing, manufacturing, applying for registration or using commodity bar codes.

Don't treat bar codes as fake artifacts;
In order to verify the credibility of the code scanning software, the reporter did an experiment, bought a bottle of red wine, a bottle of shower gel and a box of imported chocolate in a regular supermarket, and scanned it with three different code scanning software. The results show that a code scanning software can't scan the relevant information of imported chocolate.
From the above experiment, we can see that "bar code can reflect the origin, manufacturer, variety and other contents of goods, and its main function is to trace the information of goods, which can not be completely confirmed by bar code."
According to Zheng Xiao, who is engaged in software development, most of the code scanning software currently used by citizens is developed by enterprises, not official data. Its essence is to rely on the software database established in the background. If the information of related commodities is not stored in the database for the time being, when scanning commodities with code scanning software, even genuine products will not be able to scan any information.
Similarly, if the illegal merchants who produce fakes steal the bar codes of regular merchants, consumers may be fakes even if they scan the information.
The hotline reminds you that when shopping, you can't use the bar code scanning results as the only reference to distinguish the authenticity of goods. When we find that the barcode scanning information is blank or the query results are inconsistent with the actual labeling, it is best to consult and verify with the merchants before deciding whether to buy.
