It's not a CFA (consumer finance account) -- those tend to be product financing lines -- like from a furniture store, financing a new A/C through the manufacturer, or - as you mentioned - some payday loan companies.
Your overdraft protection from your CU may be viewed as a revolving credit account (like a CLOC) or possibly categorized as "other loans" on your credit report; but it shouldn't be flagged as CFA.
Thanks guys!
