A little background information: -Discover/Great Lakes only allows payments made directly from a bank account using a routing number and account number -I have a great rewards credit card, where i get 1% back each month on my purchases -I wanted to pay the debt off in portions using my credit card to get the %1 back, obviously paying off the credit card each month. Is there a way around this problem? Can a credit card issue an account number and routing number? I'm a member of the Pentagon Federal Credit Union that is linked to my credit card.
