The coffee machine in our office is controlled by blockchain NFTs and a Raspberry Pi: Once authenticated, an owner of the NFT can select their coffee type on their phone which then signals the Raspberry Pi to make whatever coffee type was selected by jumping the contacts that used to be pressed by the machine's buttons (which have been removed). It's a cool gimmick, fun to show off to visitors, gives us a nice record…
Everyone in every office would pay good money for that.
