I don't think it requires any specific precision (within reasonable limits, of course) since smartphones are expected to read it in pretty harsh conditions, therefore QR codes should have a good allowance for errors (squares remain squares). In fact, I don't really know but I see how bar codes are scanned at a cashier's counter, and sometimes it is fascinating how they can be successfully read at all. I'm more curious whether anyone actually tried to scan the QR code on the photo and what info they managed to extract. Is it a real Bitcoin wallet and what is its balance (just curious)?
