If you need a microchip to tell apart the counterfeit, why would a consumer even care? Either you can tell by quality or you buy the cheaper one.
Because this is between wholesalers and their customers. Not the consumer in the supermarket.
Cant they just make a digiyal signature on a QR code?
It’s very simple to just print the same QR on the cheese by just taking a picture of it. The barrier to counterfeit the cheese is considerably higher if the measure is harder to copy.
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
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.
