I've got a CitiCard, and they offer 'one-time-only' credit card numbers.
You just log onto the web site (or use their application), and it'll give
you an account number that's valid for one use, with an expiration date
one month away. It's great for online purchases.

American Express has offered this for quite a while. The only problem I've
run into is their poor server response sometimes when I'm trying to get a
number; the expiration month given is for the current month. I agree that
it's a boon for online purchases.
