WSJ had an article on personal cards in their weekend edition. It's a cute but silly idea. I have hundreds of business cards to store, why would I want to store "personal cards" that serve no function since I'd have your phone/email/facebook/linkedin if I really wanted to be in touch with you? If someone gave me a pretty little personal card, I'd toss it in the trash after I stored their info on my phone/email/facebook (if I do at all).
