Gateways, otherwise known as payment gateways, are a system of technologies that allow for electronic transactions to proceed. The purchase process is just that – a multi-stop journey where payments are launched into the e-commerce ether before arriving at their final destination, which are merchants’ bank accounts. Gateways serve as the middleman, relaying transactions to credit card networks that then process and determine authorization. In short, if credit, debit cards and mobile wallets serve as the payment method, gateways are the payment means.
