I'm really new to using credit/debit cards and right now I'm using Navy Federal
There is a NavCheck option and I know there's a $500 limit for overdrafting
I also know that it's an option when you don't have anymore balance in your checking account and really need money for emergencies.
Other than that, how does the NavCheck work?
Does it have an interest rate? If so, how often and how much do they charge you for it?
Does it affect your credit score?
