Will AllowStoringCreditCardNumber = 1 store credit card info

If I set the default for "AllowStoringCreditCardNumber" to "1" in the Nop_Order table,
will credit card information be stored when an order is placed?

It works for Manual, but I'm using Authorize.net, and it is not storing the info.

No, it won't. This value is set in an appropriate payment plugin. Open \Plugins\Nop.Plugin.Payments.Manual\ManualPaymentProcessor.cs file and have a look at 'ProcessPayment' method

Hi MikeMC SD and a.m.

I have the same request from my position here at work. We use authorize.net and need for credit card info to be saved so that our users don't have to continuously punch in there card info every time. I will go ahead and take a look at the class you suggested a.m. but just wanted to know if anyone has already developed a way to do this for authorize.net yet.

Thanks in advance.
