QR codes are being used in many different instances today. I used http://delivr.com/qr-code-generator to create my codes. You can use them to create things like a scavenger hunt, or to create different questions for your students to answer. It would be interesting for the students to use this because they could further their use of technology. It would also interest them, and make them discover new ways to use QR codes. QR codes are very easy to use if you have something to scan them, and it will allow you to easily scan the code and get the information quickly. They can be used for many different purposes, and are very helpful overall.
