QR codes seem pretty cool, but only if you have a device that can read them. It is an easy way to sign up for a sweepstakes, or get free coupons. People can also use these for inspirational quotes, or advertisements! This is really cool, and a great leap into the future.
I could see teachers using these to have links to sites for extra credit, or additional notes and things like that. These little figures, could be used in a really cool way!
