Start Accepting Credit Cards

* Online payment gateway

* The payment gateway is a link between the Payment Processor and your Web site (or the Web site your goods are hosted on). When your customer makes an online purchase, the information from your Web site must be sent through a payment gateway before an authorization is obtained. After the authorization is obtained, the Payment Processor must transfer any funds through the payment gateway.

The shopping cart collects items from your customer, adds up the item's costs, calculates taxes and shipping costs, and provides a total amount to the customer. A payment gateway's function is to collect the purchaser's name, address, credit card number, and expiration date.

The payment gateway securely sends this information and verifies that the purchaser has enough funds in their account to pay for products ordered and that those funds may be deposited into the merchant's account.

Make sure you understand fully the product/service you are purchasing.
