Updating a credit card using Shop Site cart?

[enzymelady]

I offer auto-shipment and sometimes my users need to update their credit card but I use manual processing. Is there any way to use Shop Site to provide a secure method for customers to update their cards? I tried creating a "product" called "Update my Credit Card" that I could send customers a link to using order anywhere. But with a $0 value, it won't let people enter payment info. I could enter $.01 as the total and let people know they will not be charged anything, but wish I could use the form to update without any totals. Any ideas?

I know I could create a form and use this, but since my customers are used to Shop Site and it's all securely stored and encrypted, I was hoping to use the functionality instead of creating something else that I'll have to maintain.

Thanks for any advice.

There is no built in way to have the shopper update there credit card info. Since you are manually processing credit cards you could create a form on a secure page and have them use that to submit the information. We use such a form for merchants to submit their store login info to us for support issues, but we had to have a special script written to handle it.
