Is there a difference between different packages of Lanrun?

Drugs are slightly different from other commodities. Sometimes you will see two bar codes on the package. One is a 20-digit number, which is the label given to each drug by China Food and Drug Administration.

The symbol of commodity bar code is to "translate" the code of commodity into "bar code" with different widths for machine reading. This commodity code is the key to the computer information database. With this "key", consumers can query the relevant information of goods, such as manufacturer, specification, quantity, price, production date, anti-counterfeiting information and so on. The bar code itself does not contain this information, so it is impossible to directly judge the authenticity of the goods. At present, bar codes have been widely used in the field of food and drug safety traceability. If we establish a product traceability system based on commodity bar code technology and collect the relevant information of products in the circulation supply chain, it will help consumers understand the manufacturer, shelf life, batch number, ingredients and other information, and then help consumers distinguish the authenticity of products.
