The image to your left is a quick response (QR), or 2D bar code. This seemingly jumbled mess of dots and shapes have been around since the mid 1990’s and was originally used to track parts in vehicle manufacturing. Now many camera phones and tablets like the iPad have programs that can interpret this image (known as mobile tagging), and it can be used to display a text message, compose an email, or take you to a website.
You can generate a code to “point” to any virtual space, including website URL’s, social media sites, photo galleries and text documents. If it has a web address, you can link to it. QR codes can also be used to deliver a message as text, contact details (name, phone and email address) or to send an SMS text.
When a user sees a QR code, they can launch a media reader app or program in their phones (many phones come pre-installed with them) and then “scan” it with their Smartphone camera, essentially taking a picture of it. The app takes care of translating the image into the link and automatically connecting the user to the information.
