How to use QR codes?
If you have a smartphone, you can use these codes quite easily. All you have to do is download a QR code scanning app from your device’s app store, open it and use it to take a picture of the code. It’ll decode the QR code and then do the action the QR code is asking you to do.
Here is a list of good QR code scanners for each of the major mobile operating systems with direct download links.
