Several weeks ago I was browsing and reading various school librarian blogs when I came across the use of QR codes. QR represents quick response. Data such as text, hyperlinks, personal or professional contact information or geo location (just to name a few examples) are embedded in these square mosaic designs. Once I knew what they were I started seeing them more and more often. Within days of reading about this use of technology I purchased an orchid plant. On the back of the company's tag was a QR code. When scanned it directed me to a web site with beautiful photographs and a multitude of useful and interesting knowledge about orchids.
Smart phones or other mobile devices that contain a QR code reader application are used to scan the QR code and will display what the creator desires. A simple search on your favorite site will include a list of the best applications for your particular phone. I downloaded the Android QuickMark app for my new Samsung Fascinate Galaxy S phone from Verizon.
At this link Dana Huff, a teacher at Weber School, a private high school in the Altanta metro-area gives an excellent, brief overview of QR codes, their creative function in the classroom setting and additional resources regarding this new (at least to me) cool technology. An additional recent post of possible uses can be found at New Media Photographer Digital Marketing Blog by Rosh Sillars. While geared more for business without too much of a stretch of your imagination these suggestions could be utilized for educational purposes.
