Is it possible to securely accept credit cards with Gravity Forms without using the PayPal or Authorize.Net add-ons?
I would like to make a simple form in a WordPress page where a customer can place an order and enter their credit card info without the form submission going through a payment gateway.
The form submission would come to us instead and we would make a manual transaction at our Authorize.Net user interface in order to bank the money. We want to confirm the order with the customer by phone first before charging the card.
I don't know how this could be done securely with Gravity Forms without the PayPal or Authorize.Net add-ons. We have an SSL cert and the form would be posted with a secure (https) url but I have a couple of questions:
1. How do you send the credit card info securely when we receive the form submission in our email? Regular email channels are insecure.
2. Is it possible to store the credit card info securely in the database with the rest of the form submission entries or leave out the credit card info from the entry altogether?
3. What is the best way to accomplish this?
