    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.

      Make QR a link. Consumer access the website and sees aproximate information about previous scanners with some of items identified as warehouses and shops.

      That’s the route of cheese for you, and for them. Not ideal but can help you avoid doubles.

      Until forgers’ cheese sells first and you have false-negatives (:

      I find it hilarious that cheese wheels get defended more than money bills rather than having authorized resellers or something alike. I feel it’s more like DRM in a sense that making these chips is a business too, and someone found a customer in these scared cheesemakers.

    • You can encode the first order or link to a tracking website. Depending on the depths of the supply chain this means the wholesellers name needs to match with the factory, production and sale date. If there is 20 steps in between this would get difficult, but such a supply chain should not be trusted in the first place. So it would do the same as the tracker chip. And since there is no encryption mentioned, the signal of the tracking chip could be as easily copied as the QR code.

        factory, production and sale date

        nobody later in the supply chain will have any way of verifying what the production date or factory of their cheese should be

        the sale date would only really apply if the same cheese is never sold twice, which seems unlikely and not very scalable

        the signal of the tracking chip could be as easily copied as the QR code

        it’s significantly harder to copy an embedded proprietary ID chip than it is a QR code
