Quick Response Codes

     I have been curious as to how QR Codes can be used in an educational setting.  I understand their use in commercial apps but am wondering how do I bring them into my library programs.  
One of my high school librarians created one for her school's library Web page and using analytics kept track of hits and only had two!  One was from the school's technology coordinator.  So I guess that means that we need to educate our users--but before that, I think we need to determine if the tool has a place or is it just a fun gizmo.  
    We have a mobile app for our online catalog but I am not sure how many people are using it.  I am curious ---anybody out there want to share how they are using QR codes?
