AT&T has my boss's card on file for paying for my iPhone service. He didn't realize it would store it, and now that it has I could easily go in and pay my bill on his card if I wanted (which I haven't done- but in a pinch it's nice to know if he's out sick or something)- he logs in every month to pay it, but it's funny that his involvement isn't actually necessary with his card on file.
