Have any of you used business cards before to pass a girl your number in those quick moments?

For example, I met this girl at a wedding the other day. She’s actually the grooms cousin. We hit it off at the reception, and the flirting couldn’t have been more obvious. But we got separated, I spent some time with the groom, and didn’t see her again.

That ship sailed but my friend said I should get a business card. Hand it out, quick number exchange when you’re in a rush. Anyone ever tried it? Did it work ? I can tell if that’s cringe or not.
