I'm trying to modify the credit card form to add some new custom fields named "Bank Name" and "Bank Phone Number" and it seems this cannot be done through the back-end.
I've searched the web and on here but I haven't been able to find anything in reference on how to add a new custom field to the credit card form. I would think it's almost the same as adding a new field to the customer registration form but I have no clue what to do database wise.
If anyone has anything I can use to work on this, I'd greatly appreciate it.
