I was checking out the QR (Quick Response) Codes in a Lucky magazine the other day. I downloaded a free QR Code reader on my iPhone and used it and my phone’s camera to “scan” these symbols on various pages. Usually the codes displayed the website of the vendor in the ad or article.
These codes link a physical object to digital data. The data could be anything, it doesn’t have to be a webpage. It could be contact information, a map, details about a piece of art, registration form, etc. Check out my QR Codes Flickr Gallery to view some images of codes in the wild.
I’m intrigued by how these might be used in the classroom. It is easy to create QR Codes, with no cost involved. The biggest obstacle I see is the smart phone requirement. Not everyone has a smart phone. I learned from the presentation below by awyatt that there are computer programs you can install for scanning QR Codes with webcams, but I can’t envision that implementation.
Did you try out the QR Code above?
