QR codes are a really interesting piece of technology with far-reaching implications. What's interesting to me is the evolution of QR codes in the future... I think the ever-smaller internet devices on the market, combined with the prevalence of free app-sharing, will lead us to a future envisioned previously only in science fiction.
How do QR codes come into play, you ask? With the amount of information a QR code can store, I predict that QR codes (or a future derivative of them) will be used in place of business memos, encrypted messages for government services, and even personal ID information.
While the details on how this could all be implemented effectively are currently out of my reach, I think the possibilities for this kind of technology are almost literally endless.
