QR code as tourism tool

Would not a QR Code be just the right tool on this sign to connect the physical world to the virtual one ? When walking in the streets of Neuchâtel on this sunny day I would have love when i met this sign to shoot the QR code associated that would have sent me online to some explanations of what I was looking at.

Of course nothing new here… Semapedia is just one first example of what I am talking here but it looks like a very easy first step to do. BTW… KAYWA Reader also reads matrix code… semacode (the code uses on semapedia) is not a problem then…

(the worst part of this post is that I have not found any explanations online about the sign on the picture… guess Tourism offices still have to enter in the 21st century)
