NFCU does not have credit criteria for secured cards, except that you must secure it.
There is no application. Once you have funds in savings, you call in and tell them you want a secured card and for what amount (which must be in savings). They will put a freeze on that amount of savings and issue the card. I have never heard of a denial for any reason.
They do pull your credit report, but only to determine what interest rate you'll get.
P.S. Anybody have luck getting Navy Federal tell you what your FICO score was when they pulled your report?
