How does Liqun check the authenticity of bar codes?

The identification steps are as follows:

1. Find the barcode on the packaging of Liqun products and aim it at the scanner or mobile phone camera in the light.

2. After scanning or taking photos, a QR code or product information will appear. You can confirm the authenticity of the goods by scanning the QR code or querying the information of the goods.

3. The information that appears after scanning is inconsistent with the information on the product packaging, or there is no information showing that the product is a fake. Don't buy it.
