What is a closed payment?
Closed-loop payment cards are any type of electronic payment card that can be used only from a single organization. Closed-loop cards are generally issued through the business itself (the merchant) in conjunction with a backing agent such as Discover or Visa.
Should you make payments on closed accounts?
It's important that you keep making at least the minimum payment on time each month, even after the account is closed, to protect your credit score. Late payments will hurt your credit score just as if the credit card was still open.
