QR Codes in the Library

The use of  quick response codes is quickly becoming a new and innovative way to keep students connected to school.  If or when cell phone use is allowed within libraries in my school district, I would love to implement the use of QR codes.  How neat would it be if my students could scan a tag (QR code) off the library newsletter and get a podcast of me providing important information regarding the library to not only to them but to their teachers and parents, too?  I would also like to use the QR codes to give important tutorials on multimedia use or provide students with archived lessons.  Also, I could provide tags that students could scan that would automatically take them to an author's webpage.  Or how about tags that would direct them to previews and reviews of new books that are been added  to our library?  And of course, I would love to have a couple of visible tags through out the library that would instantly provided the student with our library online catalog.  I think that the use of QR codes is becoming more  and more mainstream and will eventually be used everywhere.  Until then, maybe I could request a class set of ipods or ipads that will eliminate some of the distractions that come with cell phone usage, and still have the advantages of this wonderful technology.
