How do I set up a "virtual credit card machine" on my website? - buy credit card machine

I'm trying to create a website for an online shop. How can I create one of these forms of credit cards that you make when you buy something online, so if customers want to buy, they can fill out the paperwork and the money is automatically transferred to my account?
