QR Codes are a popular two-dimensional matrix code, originating from Japan where most mobile phones can read these codes. Originally used for tracking parts in manufacturing QR Codes are now being used worldwide for mobile tagging. While QR Codes can hold any sort of text information, hyperlinks (URLs) are the most common and effective, connecting the real world with the internet. People with a modern camera phone can scan the QR Code and the URL will open in the browser of the phone to display more information. This is often being used for billboard advertisements, on historical buildings or for city tours.
While the standard QR Code is just a simple matrix code, with a trick it is possible to include some graphical elements like text or a logo, as used by the BBC and others.
My first adaptation was a green vegan ‘V’ for a Vegalicious T-Shirt in the center of the QR Code, which links to Vegalicious. The next design used a red heart icon in the same pixel style as the QR Code. When someone scans this QR Code it will display a text message.
The next example links the icon of Creative Commons to their home page and the Attribution-NonCommercial-ShareAlike license QR Codes to the BY-NC-SA license deed page. This is an easy way to provide a link back to the license page on a visual medium like a record cover, a printed book or a piece of art.
