QR Codes
All you need to know
What is a QR code?
QR stands for Quick Response code. QR codes are typically a square pattern made up of blocks. When scanned by a tablet or mobile phone, they redirect the user to an online resource. The resource may be a website, a YouTube video, a text file or a file stored on Google drive.
How do I make a QR code?
There are a number sites that let you create QR codes for free. Please see below for a couple of suggestions:
QRstuff.com and P-QR.com
Typically, you paste in the URL you want to link to and the site generates the QR code for you, which you can download and add to posters, handouts etc.
You can create two types of QR codes: a static code, which is linked to a fixed location, or a dynamic code that lets you change the location that the code is pointing to.
QR codes are typically black and white, but it is suggested you use different colours to highlight the type of content the code is linking to. For example, video could be blue: it's a good way of warning users on 3G that they want to connect to a WiFi hotspot before scanning the code.
How do you read the code?
There a number of QR code reader apps available for free from both the Apple App store and the Google Play store.
