A large QR Code has been seen at many of London’s most famous tourist attractions. The organizers of QR World Expo are promoting the world’s first QR Code exhibition to be held in London later this year. The QR Code resolves to the QR World Expo website where visitors can register their interest for the event.
The designer forgot the security white zone around the code, so you won’t always be able to scan the code.
