We are launching a website soon where people can purchase a product. We have a merchant account and use Authorize.net for our gateway. Authorize.net allows us to store CC information on their end for $20 a month in their customer information manager in complete PCI compliance. And using an API we can call get the CC info when we need it... however, It's not me that needs it, it's my fulfillment house, and they need the data stored in their server. I need to be able to send this information securely to the fulfillment house so they can manage re-curring billing and order cancellations, etc... They have their own computer system. They will want the information in a CSV so they can import it into their system. I can use the API protocol to grab the data in a batch cycle and create a CSV with some coding, however, I don't know how to send it... I think email is a bad idea for obvious reasons. What type of encryption do I need?.. And what method should I use to send it to them?
