This clever idea i noted from Tiger Stores which is part of a Danish chain store network of retail shops. They have sign up cards next to the cash register. Here a customer can fill it in right away or take the flyer with them and sign up via scanning the QR Code. It then opens onto a Tiger Danish page where the user is offered the English translation. (location specific). Here the user clicks yes.
Then they pop in their email address and are then registered for news from Tiger stores.
