A few months ago, I ran into a friend from high school on the train to New York. She gave me two business cards — the first was her proper business card, complete with work phone number, office address, fax machine, etc., and the other, is this cheeky, more social version which she uses “to talk to boys in bars.”
The front is pretty standard, featuring first and last name, email, and mobile phone number. The back is a straight-up checklist of traits which must be exhibited by any party interested in future social interaction. And if you don’t meet these stated criteria, this card will self-destruct, apparently.
