a though has occured to me (that;s like a WOW moment for me).
can a credit card account, while it is an open and usable account be considered an open account be converted to a written contract situation? Since the account is no longer usable, it is in actuality not an open account. The terms of these accounts often change once they are deemed unusable any longer.
that would explain the acceptance of the states considering a CC account as a written agreement rather than an open account, would it not?
just a thought (remember this, they are like eclipses. they don;t happen very often but man, when they do, they are impressive

)
