Accepting Credit Cards On The Web

For this part, all I need is information. The information needed is what must be done to accept credit cards on the web. I do have a web server and have SSL as well. I developed an E-Commerce Application. I'm assuming a payment gateway is needed. I need a list of companies that can be used where I have a form a customer fill out. Then when they click submit, then it goes to the payment gateway server. Once the transaction is approved, it communicates it with my server so the transaction can be processed further. The only payment gateways I've seen so far are the ones where either everything has to be on their server or it does not communicate with my server once its been approved. I need the lowest cost payment gateways possible. ## Deliverables The list of payment gateways. There should be at least 5 or 6 on the list. Should list the ones with the cheapest rates possible. However, it must be real time automatic where a customer fills out a customized form on my server including the credit card information. Then the information gets sent to the payment gateway. Once completed, it will communicate with my server so the customer will know the transaction is approved and my system will know without having to manually goto their site to find out. ## Platform Windows 2000 Server Edition.
