U.S. cards just have the card number, which of course is separate from the account number, and then there's the "security code" on the back, which is typically a 3 or 4 digit number. But there is no other account information printed on the card.

Also, I found out when I began working for international clients, the U.S. doesn't participate in the IBAN system. Instead we have something else which necessitates international wire transfer payments be made via an account number, a routing number, and a swift number. It's very annoying. (perhaps business accounts work differently, I get paid directly into my personal account which I'm sure is a bad idea, but it works for me).
