Creating QR codes is not difficult, especially if practitioners/learners/stakeholders are using an application like QRals. A new (and free) web tool allowing practioners, learners and other stakeholders (with minimal technical skills) to have as many QR codes generated and used as they could possibly need.
Users are able to enter different content including text, links, email address, MeCards, Bizcards, SMS etc. They can also select the colours to be used, and the actual size of the QR Code itself.
Easy to use and users can download the resulting image to their computer. Every QR code also gets a bit.ly url for the image!
