What are Payment Gateways?

A payment gateway is a technology that facilitates online transactions by securely processing payments between customers and merchants. It acts as an intermediary between the customer’s bank and the merchant’s bank, ensuring sensitive data, such as credit card details, are transmitted securely using encryption. Payment gateways handle authorization, ensuring the transaction is valid and funds are available before processing payment. They also support multiple payment methods, including credit cards, debit cards, and digital wallets. Overall, payment gateways simplify and secure the payment process, making online purchases smooth and reliable for both businesses and consumers.
