>Strangely, he never has any business cards on him (people always ask). So he asks them to give him their phone number instead.

Did you mean the "Strangely" here? What he's doing is, in fact, very clever. A business card is a passive, easy thing that will rarely lead to further action. Asking for the phone number is a much better gauge of how serious the person is.
