If your QR code scanner is not working, try the following: Ensure your camera lens is clean and that you're in a well-lit area. Check if the QR code is too small or too far away. Restart the app or your device. Update the QR scanner app--or your device’s operating system--to the latest version. If these steps don’t work, try using a different QR code scanner app. It’s possible the QR code itself is damaged or not a valid code.
