New Credit Card Handling for Authorize.Net MicroNet supports several methods for processing credit cards, including Authorize.NET and Heartland Payment Systems. New option added for Authorize.NET called Direct Payment Method. With DPM the consumer’s credit card information is transmitted from their browser to Authorize.NET’s servers. This will significantly help those in the process of getting PCI certification. Over the next few weeks we will be in touch to switch all of our customers who use Authorize.NET over to this new method.
