As you can see, the credit card data goes to your merchant bank, and the merchant bank sends an approved or denied message to Gahela to process or decline the order. The only data going to your server is the customer's registration data.
- Since your server doesn't handle credit card data it is much easier to be PCI-Compliant
- Customers can store their credit card data for future use. But you never store the actual credit card data, just a token that can only be used on your site with the Authorize.Net processor.
- Customer can manage multiple-credit cards on your site
- This method can be used to make payments, or for recurring billing.
