We have a WPF application that's integrated with credit card processing information. We have the info swiped into a WPF web browser for PCI compliance. Our browser is PCI compliant and our code never deals with the credit information. But now we're trying to have a stand-alone PCI compliant WPF control that we can plug in, instead of the web browser. But we're not sure how to accomplish this and be PCI compliant. Can someone help?
