What is a QR Code?

A QR code is a two-dimensional barcode that can be read by most smartphones. QR is short for Quick Response. On the right is an example QR code that links to the montana.edu website.

QR codes can contain more than just links, they can contain contact info, addresses, or any other text based data (limited to about 4,000 characters.) They are most common to see in print based applications such as an advertisement or a business card. A user can then quickly use his or her phone to scan the code and be taken to a site for more information.

A lot of smartphones have built-in functionality for scanning QR codes. On other devices, such as the Apple iPhone, an application must be downloaded in order to read QR codes. The QR code is then scanned by the smartphone's camera and the link or text is displayed.
