.Here is a tutorial prepared by our Spanish partners describing how to set up a QR code. We here in Britain at least, were really impressed by the work created by the Spanish students in creating and sharing this, Thanks Marta :)

My apologies to Marta, Power Point is not brilliant for embeding onto the twin space, so I have uploaded your twin space onto a Sway  

Be warned the Sway takes a few seconds to load, have a brew and a biscuit while you wait.  (This my fault and not the Spanish authors)
