A QR code can use one of four error correction levels. Higher error correction forces denser codes, but allows scanning in more situations. A trade-off!
Many restaurants have their menu just being a qr code nowadays. It became usual during covid, but manu stull keep it on the tables. The other day I was told explicitly to use it since they didn’t have a physical version.
