Payment Gateway

Definition

A merchant service provided by an e-commerce application service provider that authorizes credit card or direct payments processing for e-businesses.

Deep Dive

A payment gateway is a crucial merchant service that authorizes credit card or direct payments processing for e-businesses and traditional brick-and-mortar stores. It acts as a secure intermediary between a customer's bank (or chosen payment method) and the merchant's bank account, encrypting sensitive financial information during the transaction process. When a customer initiates a payment online, the gateway quickly transmits the transaction details to the acquiring bank and subsequently to the card network, ensuring secure data exchange and transaction approval or denial.
