What is a QR code? It’s similar to a barcode, but it can hold a lot more information. All you need to scan a QR code is a smart phone, or other mobile device, and a QR reader app (http://www.beetagg.com/en/beetagg-qr-reader/). These square codes can be found on just about anything, from soda cans to magazines! At the library, we are using QR codes to help you find new books. Look for one in a copy of your favorite book, once scanned the code will take you to a list of similar titles!
I think that this is a great advertisement for an app. It has lots of color, making the reader want to look at it, it has enough information, but not so much that the reader won't bother to read it. It gets the point across through bright colors, a simplified, condensed amount of information, and appealing illustrations.
