QR Treasure Hunt Generator.
The QR Treasure Hunt Generator provides you with all of the things you need to get started creating your own QR codes and using them in your classroom. To use the QR Treasure Hunt Generator type out a series of questions and answers, generate the QR codes using the tool Russel Tarr provides, then print and display the codes around your classroom or school.

If you're looking for a QR code reader app, I use and recommend QR Droid for Android devices. For iOS devices take a look at QR Scanner or QR Code Reader.
Applications for Education
Creating QR Treasure Hunts could be a great way to get students moving and learning at the same time. With a QR Treasure Hunt a quest for information can become a physical exercise as well as an intellectual exercise.
