Does anybody know of a company or person making physical badges? Like an embroidered patch or something? Sure, it's kind of old school, but some people like to attach pieces of flair to backpacks or whatever.
Making badges is easy. The hard part is implementing badge rights management (BRM) that prevents malicious users from duplicating badges that they haven't earned.
Badge piracy is a serious issue. For every legitimate, physical badge made by hard-working badge manufacturers and developers, there are sixteen (16) illegally created badges in the world.
Fraudulent badges can be identified from their frayed edges, cheap colours that wash out in the rain and increased likelihood of being infused with narcotics and/or bloody pieces of glass. While these badges may be cheaper and easier to find than authentic badges, their quality is nowhere near the same level of standards as the real deal.
So please, if you find a badge that doesn't have the BRM seal on it, please report it to the Badge Manufacturers Association of America (BMAA).
I'm thinking that keeping my SO reputation up to date on a physical badge attached to my backpack is NP-hard.
