No need to type your search anymore. Just take a picture. Actually, you just need to point your phone (camera) at something, and let the information (learning) flow start!
Next time you are curious about what that is (whatever or wherever it is!), if it is tagged, GPS and Google Googles will take care of business (Field trips to next level!). This makes QR code look like an outdated dinosaur. Wait, why not use both to good effect :)
