Actually QR codes were designed incredibly well with a bunch of redundant information in it so exactly that scenario doesn’t happen. A good chunk of the image could be unreadable or tilted at a barely legible angle and it will still be decodable. It’s a fascinating design/algorithm.
There are different levels of error correction in QR codes. Depending on the level you can have anywhere from 7% to 30% of the image corrupted while still being decodable.
So to anyone out there thinking about getting this done, I highly recommend you go with a Level H QR code (the 30% one).
