QR codes

For my post for today I decided to write a little pre-face about QR codes to build up to my post (coming soon) on how schools can use QR codes.

A lot of people have seen QR codes recently but not everybody know what they are or how they are used. But a normal QR code looks something like this:

QR code (abbreviated from Quick Response Code) is the trademark for a type of matrix barcode (or two-dimensional barcode). Originally designed for industrial uses, QR codes have become common in consumer advertising. Typically, a smartphone is used as a QR-code scanner, displaying the code and converting it to some useful form (such as a standard URL for a website, thereby obviating the need for a user to type it manually into a web browser).

In order to use a QR code you have to have a smart-device running Android or an iOS device (like the iPad/iPhone) where you can download QRscanner Apps like RedLaser or QRreader for example. I could write so much more about QR codes but I think this video explains it better:

You can create your own QR code in a QR code generator like goqr.me. but I suggest you make a more beautiful one with Unitag

Since the QR code is more complicated if it’s a long URL I suggest you shorten your URL by using a free service like Bitly.
Then your QR code looks more like this:

Now you know what it is, I hope you try making your own using your (shortened) twitter URL or Facebook for example.

Enjoy it, Ingvi Hrannar.
