PCI Security Related: How to authenticate large credit card transactions?
This one is a little off the beaten path for EE - but hey nothing ventured..
We take some very large credit card transactions over the phone for our services. e.g. like $50,000 for a single transaction. In order to authenticate the person we typically require the customer to fax in a copy of drivers license and the credit card. I was hoping a security pro might be able to advise on another method of verifying that the customer is who they say they are and is authorized to use that particular credit card. Thank you.
