    how do you stop me re-using the same QR code on multiple cheeses?

    you can encode the contents of a document in the QR code that you’re verifying to make sure it matches

    you can’t encode cheese into a QR code

      Make the qr code an NFT. Then you can’t copy paste it or else you’ll have crypto bros having fits in your dms.
