Ensure Good Lighting
Good lighting is critical for your built-in camera to accurately capture the QR code. Ensure that there are no shadows or glare on the code.
Keep the QR Code in Focus
Make sure that the camera is focused on the QR code and that it is not too far away. Adjust the distance until the camera can capture the entire code clearly.
Troubleshooting Common QR Code Scanning Issues
Despite the simplicity of scanning QR codes, you may encounter some common issues. Here’s how to troubleshoot effectively.
