I would also like to point out, the amount of data in these QR codes probably isn't that much (depending on how the app is set up, it is probably some sort of ID number, or name only recognisable to the app) this could allow them to have a high data recovery rate (a feature built into qr codes) meaning even some serious tampering won't have an impact (the qr codes with a picture in the middle isn't a standard it is litterally people just covering up the QR codes and making the data recovery do the work)
