Google Profile Business Cards

So I responded to the Google promo to get some free business cards for setting up a Google Profile. It has the Google logo on it with my name... and ah nothing else....?

So why would I want to use these cards again? I guess the card is telling people to go to Google type in my name and then they can see my profile. That trumps the business card hands down. Bonus, for a limited time I can get 250 more useless cards with just my name on it for $19.95.
