QR Codes in Education: 

QR codes can be as large as a poster or small enough to fit in the corner of a worksheet. They can be creative sources of valuable information for your students. All this in a way that engages students and peaks their interest.

Download any barcode or QR reader to your SmartPhone (I reccomend Red Laser) and try reading my QR Code.

Then make your own using the QR generators listed below.


From Wikipedia:
A QR code (abbreviation for Quick Response code) is a specific matrix barcode (or two-dimensional code) that is readable by dedicated QR barcode readers and camera telephones. The code consists of black modules arranged in a square pattern on a white background. The information encoded may be text, URL, or other data.

There are many different websites that offer QR code services, some pay, some free, some free but with additional advertising. Here are a few sites I have used below, feel free to add your own.

ZXing ("Zebra Crossing")
A very simple free QR code generator.
ZXing (pronounced "zebra crossing") is an open-source, multi-format 1D/2D barcode image processing library implemented in Java. Our focus is on using the built-in camera on mobile phones to photograph and decode barcodes on the device, without communicating with a server.
