If you are actually looking to track who is trained in what, you are going to want all of the information in a centralized location. I recommend Google Sheets. The badges may be cool, but if the team leadership every wants to find out everyone who is qualified in something, they are not going to run around your team looking at everyone's badges, they are going to look at a spreadsheet. If you want everyone on the team to know who is qualified in what, I recommend posting lists on the wall above the respective tools/areas. It's a lot easier to look at the wall than at someone's badge and it is a lot more obvious when someone is using a tool they shouldn't be that way.
