Offline Identity

On the surface, Facebook adding these little business cards are not a big deal (other than the scale of any initiative the company takes on). But I do think there's something more interesting here: This is another step in Facebook owning your identity in the physical world. They've already claimed you in the digital world and pretty much locked things up, but the physical world is still a hodgepodge of identities split between governments, banks and employers. There's never really been a global holder of identity data before (to my knowledge) and I'm not sure I yet understand what the implications are, but I assume it's something Facebook is thinking a lot about.
