Badges are digital indicators of professional skills and achievements displayed in a universally recognised way. The most popular scheme is probably Mozilla Open Badges. Badges allow individuals to take control of their professional achievements and abilities, and help with future education and career opportunities. From Wikipedia: 'Open Badges differ from purely visual representations of badges in that they contain metadata indicating the badge issuer, criteria for the badge, and other information, all of which is hard-coded into the image file itself.'
