I rather enjoyed this, blank business cards:

In a pleasant twist, this turns out to be a far better solution than the traditional business card. You can add a call-to-action. The act of creating a card gives you a chance to have a moment with them. You can give the appropriate amount of information. If you have multiple email addresses or websites, you can choose the right one. Nobody forgets which card is yours. And if they run out of cards, you can hand them a pen and have them make you one. It’s great.

I probably wouldn’t recommend this for everyone, this has a very “Designer” or “Avant-Garde” approach. I doubt this would have the same effect for someone in the financial world (but I could be wrong). 

That said, I’m stealing this idea….
