I love this! QR codes, or quick response codes are cell phone readable bar codes. These are used because they can store a lot of information and can be read quickly. They are in every magazine lately... QR codes can link you to sites, specials, articles, addresses. They have been widely used in Asia for a long time, and are now making a strong presence in the U.S.
Download a QR reader to your smart phone. If you click on QR you can download the app from iTunes. Now you can read my QR code above!
I'm trying to think of all the QR codes I could make and how I can use them...The possibilities are endless!
