The Average Payment Gateway
What Payment Gateways do
Payment gateways play an essential role in the processing of a credit card transaction. When you swipe your credit card or make an online purchase, a payment gateway takes payment card data and securely sends it to a payment processor for authorization.
The transaction information is then submitted to one of the credit card networks and routed to the issuing bank of the credit card holder where the transaction is either approved or declined. The response is then transmitted in reverse back to the payment gateway where it receives the response and notifies the merchant whether or not the transaction was approved or declined.
