1. Open the camera app on the Huawei P30 Pro. 2. In the live viewfinder, select the "Vision" icon at the top left. 3. Now select the symbol for "QR Codes" in the bottom left corner. 4. Now scan the QR code with the Huawei P30 Pro. 5. Now the corresponding website, business card, function etc. opens on the smartphone. So now you know the procedure to scan a QR code with the Huawei P30 Pro
