A payment gateway is a hosted software application that authorizes credit card payments and ach (check) payments between a website and a credit card processor. A payment gateway is similar to a POS (Point-of-sale) terminal located in many retail stores. Payment gateways encrypt sensitive information, such as credit card numbers, amount, and customer name, passing that info to the credit card processor, who then processes the payment through the Visa / MasterCard network. The transaction result is then sent back from the issuing bank to the credit card processor, who then returns the results of the transaction (either approval or decline) to the payment gateway. The payment gateway thus acts as the intermediary between the website and the credit card processor.
