1. Open the mask box and take out a single mask. Each mask bag has an anti-counterfeiting code.

2. Download and open the Paparecipe genuine certification APP, and then open the scanning page.

3. After opening the scanning page, align the scanning port with the security code on the mask bag.

4. Confirm that the scanned serial number is consistent with the serial number on the package. If 2 digits are inconsistent, you can manually modify it. If 3 digits are inconsistent, you need to scan again.

5. Click the authenticity confirmation button, and the identification of whether it is genuine or counterfeit will be immediately displayed. As shown in the picture below, the left side shows the genuine product and the right side shows the imitation product.
