This is a beautifully usable website. It's 23:46 where I am and I'm close to bed, but found myself comfortably reading through your copy - which I don't do for many sites.
That said, I think this is a delicate idea to pull off. The issue with business is that old people are often the most important people, and old people don't give a shit about an app for business cards, they care about business. And if I don't think the old people I come across are going to have your app, I'm not going to have it either.
So you have got to get the big people to have your app, and to do that you have to provide them with real value vs a physical business card, then find them and get them to use it.
