1, the product was labeled with a barcode, which did not meet the specifications and affected reading. For example, it sticks to a curved surface with wrinkles, uneven seams or curvature exceeding 30 degrees.

2. The barcode is wet or damaged.

3. The code reading software in the mobile phone was not updated in time, and the newly added goods in the commodity coding center could not be recognized. It is suggested to use the' barcode traceability' software provided by the National Article Coding Center.

4. Fake barcode. Some unscrupulous businesses do not have qualifications or product standards are unqualified, so they cannot be filed in the quality supervision department. Only by generating fake barcode applications and then paying different fees to some barcode reading software companies to add them to the database will there be some products that only specific reading software can read product information.

Matters needing attention

Not every product can scan the product name, specification, price and other information with software. Many softwares usually use bar code data provided by relevant institutions, but many products have no bar code for filing.

For example, when people from China go abroad to buy things, they will not go to relevant institutions for filing if they are brought to China. Therefore, the data of many products are uploaded and maintained by some large e-commerce. When scanning commodities that have not yet entered data with a software, they will also be reminded to enter relevant information of commodities.

Products that cannot be scanned by software are not necessarily fakes, nor does it mean that such software simply does not have the function of distinguishing between true and false.
