The goal here is to transfer money from the customer's credit card account to your merchant account, or in other words to accept online payments from your customer. A merchant account is a special account you set up with your bank for receiving credit card payments. You may already have a merchant account that you established when you started accepting credit cards over the phone or at your brick-and-mortar business. However, be aware that your current merchant account may not allow Internet transactions. If it does not, you will have to convert to one that does or open a second account. To run your own payment processor web site you need good payment processor script - and we have two of them on the links above.
