Payment card types

Hi experts,

Does SAP support the use of any other credit card types apart from AMEX, MC and VISA ? If so, which check functions would be used for the other payment card types ?

I'm in the process of setting up payment cards. I have maintained the above three card types and defined my card categories. However, when it comes to determining my card categories, the system only allows me to put in the same card number under the 'Payment cards from' and 'Payment cards to' fields i.e. limiting me to just one card. In the Selection option field, it has defaulted to option BT. How do I get the system to accept a range ? What ranges will I need to enter for AMEX, MC and VISA ?
