Ever wanted to have your kids voices actually read their own work on a mobile device? You can do it with QR Codes. This is great for having your students read one of their pieces of writing and then post the writing and QR Code for others to scan with iPads. Works great and the students really have some ownership of their work. Check out the "basic" how to. This is how I have been doing it with staff using our SchoolWires class sites and a QR generator site. There are many other ways to do it, but this was pretty simple.
