Why is my QR code scanner not working?

Your phone's camera may have trouble scanning thecode if it's tilted at an angle. Make sure it's level withthe surface that the code is printed on. If you're holdingyour phone too close or too far away, it won't scan thecode. Try holding your phone about a foot away and slowlymoving it towards the QR code.
