Badges are similar to certificates, but they can also be displayed in social media, which makes them ideal for promoting and publicizing courses and programs. Badges are earned upon successful completion of a quiz or series of quizzes.
Moodle's Badge plugin allows you to design your own badge and also to make them portable so that they can be displayed on social media. Instead of having to upload them to all your social media sites, it's possible to utilize the Open Badges project and include the social media in the Open Badges Backpack.
You can know more about them by referring to https://backpack.openbadges.org/backpack/welcome.
