Hi Jimmy,
When using the SagePay Direct gateway, the Cart has been programmed to send type based on the number that the card begins with.
For example:
Visa card numbers start with a 4.
MasterCard numbers start with the number 5
American Express card numbers start with 3
Discover card numbers begin with 6
A Discover Maestro is a MasterCard but it looks like the card number can begin with either a 5 or a 6, which is most likely the reason the card is being sent as a Discover card. In order to support the Discover Maestro card type being sent as a MasterCard, additional logic would need to be programmed into the Cart.
