    An account is not needed to verify a QR code. Just take a look at what Brazil has done with QR codes. It’s everywhere and, in many places, it does exactly this, to verify the authenticity of a document, for example. I have e-signed documents and what goes on the paper is actually a QR code. It’s not difficult to imagine this being used to fight counterfeit goods.

      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.
