We used Classtool.net's cool QR Code Bookmarklet to make these QR Codes. They also have an easy to use Treasure Hunt QR Code Generator.
I used this free website builder, Weebly, to build the scavenger hunt, because it has a nice mobile interface and I could make the clue choices clickable with hyperlinks.
I would recommend that students use the free Barcode Scanner on their Android devices.
Those who have iOS devices (IPod Touch, IPad) can download the free QR Reader app.
