There are a few reasons why this error may be occurring:

  1. Our system requires that you enter a MasterCard or Visa card. If you attempt to register a card provided by another issuer, you will receive an error.
  2. A card must only be registered for a single member within a program. If your card has already been registered by another Member, you will receive an error.
  3. A card must be valid to be registered in our system. If your card has passed its expiry, you will receive an error.
