For women, a small purse might be helpful for keys, lipstick/lip balm, cash/cash card/ ID, tissues-- the stuff that men can stash in their pockets. .
Guys definitely don't stash lipstick in their pockets. Not for interviews, at least.
But really, for guys, something about this is worth discussing...I kind of think it's worth it to have a few dollars, license, debit card if you need it for whatever reason, whatever you need that day/afternoon on you and, unless you have a particularly thin wallet, leave it and the rest of your junk. You don't need a fat wallet full of copy cards, random ids, gym cards, and buy one get one free subway coupons to interview.
Er, maybe thats just my wallet

Same with keys, take a ring with your car key so you can get there and back, and a house/hotel key, so you can get back in your house/hotel that afternoon, where you can pick up and re-ring the rest of your keys.
We can put stuff in our pockets, but they can be too stuffed sometimes, too. I've definitely seen it look funny at times.
