Part of the robustness of QR codes in the physical environment is their ability to sustain "damage" and continue to function even when a part of the QR code image is obscured, defaced or removed. This is acheived by using the Reed-Solomon Error Correction algorithm - some serious algebra that happens in background when the QR code is created. The original data in the QR code is converted into a polynomial, the number of unique points required to uniquely define that polynomial is determined, and this point set is added back into the QR code so that it then also contains the original data expressed as a polynomial. If that description threatened to make your head explode, just call it "mathematically adding backup data to the QR code". There are 4 error correction levels used for QR codes, with each one adding different amounts of "backup" data depending on how much damage the QR code is expected to suffer in its intended environment, and hence how much error correction may be required: Level L - up to 7% damage Level M - up to 15% damage Level Q - up to 25% damage Level H - up to 30% damage
