What does a QR code reader do?
A QR reader can identify a standard QR code based on the three large squares outside the QR code. Once it has identified these three shapes, it knows that everything contained inside the square is a QR code. The QR reader then analyzes the QR code by breaking the whole thing down to a grid.
