Description: A gateway is a service that facilitates communication between different networks. In the context of e-commerce, a payment gateway acts as an intermediary between the customer and the merchant, ensuring that transactions are conducted securely and efficiently. This service allows for payment authorization by transferring information between the customer’s bank and the merchant’s bank. Payment gateways are essential for the operation of e-commerce platforms, as they enable businesses to accept online payments in various forms, including credit cards, debit cards, and other digital payment methods. Additionally, they offer features such as data encryption, fraud prevention, and return management, making them a crucial tool for any business operating in the digital environment. The relevance of payment gateways has grown exponentially with the rise of online commerce, providing consumers with a smoother and safer shopping experience.
