Understanding How A Payment Gateway Works

A payment gateway authorizes payment for online stores and it is a vital part necessary for e-commerce. It is used in traditional brick-and-mortar stores as well. A payment gateway enables you to accept payments securely from the customer so that it can then be processed. It enables communication of information from the origin of the payment and the processor.

How A Payment Gateway Works

The following steps are involved in the transfer of payments through a payment gateway.

The customer places an order through their phone, laptop or desktop. In this step, they choose the item that they wish to purchase and then enter the necessary payment information required to complete the transaction and make the payment. Depending on the mode of payment, they enter particular financial information. Then they click on ‘Submit’ or ‘Place order’ depending on which website they are placing their order.

When the customer pays via an online website, the information entered is encrypted by the web browser in order to protect it and keep it secure. The encryption is done using the Secure Socket Layer (SSL) encryption. This enables the payment information entered on the website by the customer to be sent to the server of the merchant.

The merchant server receives the information and then sends the details relating to the payment transaction to the payment gateway. This connection has SSL encryption as well to keep the payment related communication secure. Once this is successful the payment gateway forwards the transaction details to the payment processor that is used by the acquiring bank of the merchant. In the next step, the information from the payment processor is transferred to the card company such as MasterCard.

­­­­The issuing bank of the credit card then receives the request for payment authorization. It then sends a response via the response code back to the payment processor. In case, the transaction cannot be completed due to no funds in the account, then the response code is used to relay that message as well. Otherwise, once the payment processor receives the code, it then forwards the response to the payment gateway. The payment gateway then forwards it to the website whereby it is interpreted and then a response is shown to the merchant and the customer.

Note that it is different in the case of the Discover card or the American Express card. The payment processor takes on the role of the issuing bank instead of further sending the information forward. It provides a reply depending on whether the payment was successful, or failed back, to the payment gateway.

The seller then sends the authorizations that have been approved to the acquiring bank. The merchant usually does this by sending the authorizations in batches. This is to enable the settlement to occur. The acquiring bank then settles the amount by depositing the funds to the merchant’s account. This entire process generally takes up to 2 days.
