What is the word for someone who checks ID cards before permitting entry?

What is the word for someone who checks ID cards (to verify a person's age) before permitting entry to an event or venue? Obviously, the word most commonly used in the context of a bar is "bouncer", but that seems very specific to bars/clubs and the word carries its own baggage.

What about in non-bar contexts? In San Francisco, the Sundance Kabuki is an upscale movie theater that serves alcohol for some screens, and they have a person checking IDs at a checkpoint. The word "bouncer" just sounds wrong to me in that context, but the only alternative I can come up with is "ID checker" (which sounds equally odd to me).

Is there a better word for the person who does this job?
