Just joining the community and wanted to follow up on G Delanoe's question. It really wasn't answered only challenged. We do have a scenario where collecting credit card number/expiration date is not of value.
Our POS system is capturing the sale and payment information at a detailed level. At the end of each day, it summarizes information and passes along to SAP for posting. So in fact, I have a single invoice and payments by multiple credit cards (that I summarize at the card issuer level). As G said, it would be VERY beneficial to streamline then entry by allowing the CC fields to be optional or defined at the Credit Card Payment Method level.
Cheers
