That's a combination of having to send you a statement if there's a 
positive balance, but not if it's zero; and some money laundering 
concerns. I've seen some suggestions that "loaded" credit cards should 
be declared as if they were cash at those international borders where 
declaring cash (above some limit) is required. Whereas a debit card, or 
un-used credit limit, do not count as "cash" in those circumstances.
