All of the above is possible with a new crowd sourced project from Findables.me. It's running now on indiegogo, not Kickstarter (don't ask) but the idea is familiar. Visit the site and check out the wide variety of cases for iPads, iPhones (including a promised iPhone 5 case) and even a non Apple phone (who knew there was such a thing?) in a wide variety of colors.
The QR Code is what sets the Findables project apart, as they include a custom URL for each customer, which can display your social networking info, photo, contact info (or less if you don't feel like sharing) in a nicely designed web page.
They even have dog tags, literally, which can be used to help a good Samaritan return your pet using their QR Code! It's a new world! And with Findables, you can make sure you stay in contact with your devices!
iOS 6 is expected to bring a native QR Code reader to the iPhone so this feature will be even more valuable. Until then, you can use an app like Red Laser to scan such codes.
