Freelance game developer Burton Posey developed this augmented reality business card concept as a way for companies and individuals to "provide potential clients and associates a way to get past the logo and brand and get to know the people that make the brand happen."

Posey specifically mentions Xbox Live Avatars and Nintendo's Miis as examples for what you can import and display with the card, but the idea works for pretty much any personal avatar, be it from a casual virtual world like Second Life or a hardcore MMORPG like World of Warcraft.

Of course, you could go the much easier route of just printing your avatar on your business card -- Japan's Club Nintendo even had a promotion that handled this for you -- but that static 2D image wouldn't have the same effect as an animated version of you waving, dancing, or potentially demonstrating your talents.
