The stamp is part of Royal Mail’s Great British Railways collection and uses image-recognition technology to direct users towards online content created by Royal Mail.
Users have to download the Junaio app and select the Royal Mail channel to activate the service.
Philip Parker, spokesman for Royal Mail Stamps, said, “This is the first time a national postal service has used this kind of technology on its stamps.
“Through intelligentstamp technology, our stamps will open up to a whole new world of information, interest and fun to collectors and the millions of people who will receive them on letters.”
