What are they?
QR (Quick Response) codes are basically 3D barcodes. Being 3D as opposed to 2D, they can contain much more information that a regular barcode. They can contain up to 4000 characters (numeric, alphabetical, Kanji (Japanese/Chinese symbols). Traditional barcodes contain only 20 digits of data.
A short piece of text, a Website address, an Email address or a phone number are just some of the types of information that can be stored in a code. In Japan, where QR codes originated, they are on most business cards – providing a link to a Google Map of where to find the business, or the business website in most cases, so users can simply scan the code with their phone to get direct access to information.
Most Smartphones will have a barcode scanner as an app which will read QR codes. For the desktop you can also install a little bit of software that will use a webcam to read the codes. Whether children are using mobile devices or the webcam on a netbook, they will access digital resources in fewer clicks.
