Qr codes are a cool and useful technology. For example, I can tag the code on this page ("http://www.gutenberg.org/ebooks/22367" http://www.gutenberg.org/ebooks/22367") and store it in my app to read when I am in the train. For some reason I do this a lot. Here in Singapore, there are QR Codes everywhere and most of them are really userful. At Somerset 313 you can tag a code which opens a map on your phone showing you the shortest path to your point of interest. QR Codes are awesome!
