- Hold your device over a QR Code so that it’s clearly visible within your smartphone’s screen.
- The QR code should not take more than 50% of the screen.
- Hold the device steady.
- For best results, aim your device squarely at the code, and not at an angle.
- Try to minimize any glare from stray light sources, and scan the code in an evenly lit environment.
- If the code is in direct sunlight, you may need to cover it with your hand for the app to read it properly.
- If you’re holding your phone too close or too far away, it won’t scan the code. Try holding your phone about 30 cm away and slowly moving it towards the QR code.
- Rule of the thumb: the ratio between scanning distance and the QR Code size is 10:1.
- So if you want to scan a QR Code that is 10 square centimetres it has to be scanned from a distance of 100 centimetres.
- The phone’s lens can pick up a lot of dust and smudges that can affect image clarity. Wipe it with a soft cloth to clean it off.
