The use of QR codes to provide smart-phone interactivity to exhibits is an experimental trial. Please add any comments and observations you have about the trial below.
What are they?
QR codes are the latest version of bar codes - they look like random pixels arranged in a design typically about an inch square (see top right). If you have a smart (ie cost over 100 pounds) phone then you can point the camera at the code. The computer inside the phone decodes the picture into a web address. The phone then uses that web address to show you (say) a wikipedia article.
