The virgin card. If you have your own card, you're still a virgin. When you are devirginized, you give your card to the devirginizer. If you have at least two vcards, you're a card collector.
A fairly standard system for online business cards. Not to be confused with V card, which means virginity. However, should you confuse the two, the results should be pretty good.
