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.
Not the same code. Just like serial numbers, a different QR code in every wheel that can be verified on a website, for example.
welcome to the future, where you have to make an account on our website and link your parmesan cheese wheel to it to be sure of its authenticity

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.
