What? This seems a little... unthoughtful.

Whenever I'm at a conference I very regularly have to ask the person "Hey, your name, your number, etc" and many times I just pass them my phone to enter their contact info. This is no different. Why type it yourself when they're the ones that have ready knowledge on it and can enter it more quickly?

Because phones do not have a "don't let this guy hit any other buttons and see my private info" mode. See my reply to the "run off with your phone?" question for context.
