I've had accounts with automatic, recurring credit card billing that send me warnings to update the expiration date. And I've had other accounts that I'll log into and see the new expiration date, even though I am certain that I have not updated it yet.
I've always assumed that my credit card company somehow supplied the biller with the new expiration date. But I guess it's possible that the biller just kept trying new dates until it finds one that works. Most of the time, the new expiration date is exactly 2 or 3 years from the old one, so I suppose it can't really be that hard to figure out....
