NFC Business Cards

Just came up with a brilliant idea for Windows Phone 8 users. I got given a business card yesterday (for the first time in my life) and I thought to myself how business cards are roughly the same size of smartphone screens. Then I thought about Windows Phone 8 and how the NFC technology is only mainly being used for playing music.
What if there was an app which let you build your own business card. Then share it via NFC with other Windows Phone users. The app could then have a card contact index theme so you could scroll through your business cards.

Also, if you wants to make your business cards available without having to scan your phone, you also get a QR code.
