Credit Card Processing System is used as a interface between the bank issuing the credit card and the merchants who are getting paid by the customers. The merchant submits credit card transaction request to the credit card payment gateway on behalf of a customer. Bank which issued customer's credit card has to approve based on the authenticity of the customer using pin number. If approved, sufficient funds availability will be checked. If approved, the request has to be submitted for settlement. During the settlement funds approved for the credit card transaction are deposited into the Merchant's Bank account. In some cases, only authorization is requested and the transaction will not be sent for settlement (purchased using online shpooing). In this case, usually if no further action is taken within some number of days, the authorization expires. Merchants can submit this request if they want to verify the availability of funds on the customer’s credit card, if item is not currently in stock, or if merchant wants to review orders before shipping.
