Only the residence permit, which by law you must carry in any case (even inside CH). Does it state gender ... um, not sure, I don't think so ... my permit is in my car, downstairs, through three locked doors ... I'll get back to you if someone else doesn't.

Search this forum re. carrying the permit, by the way -- you'll find some interesting info. Being American, I believe you would get the new credit card-style permit which makes it a lot easier to carry.

EDIT: Beaten by seconds by Buttercupbananatush! Anyway, I can confirm that you do need to carry your permit at all times. Theoretically.
