I'm sure you've seen QR codes popping up everywhere. Flip through any magazine and you will see them on a number of ads. What are these? They are bar codes that can send you to a website or information for a company. You can easily download an app from many cell phones (I personally use ScanLife) to quickly scan the code and see usefully information from many companies.
These codes are still growing in popularity in the US. It is still undetermined if they will fully take off but they are very popular in Europe & Japan providing mass transit schedules and restaurant menus.
I have played around a little with QR codes but definitely have not used them to their full extend. Do you use QR Codes? Have them been successful?
