Pizza Hut has created a temporary tattoo in the UK with in-built QR code that, when scanned with a smartphone, allows users to almost instantly order a pizza. The ‘groundbreaking’ concept, which has been months in development, promises to make it easier for consumers to get their favourite pizza delivered – or, alternatively, they can order and collect in person at their nearest Pizza Hut store. The fast food chain will initially make 40 available to the public as part of a marketing stunt.
