A checkout gateway is a secure and efficient online payment processing system that allows customers to complete their purchases on e-commerce websites. It acts as a bridge between the customer’s payment information and the merchant’s bank account, ensuring that transactions are processed smoothly and securely. The checkout gateway encrypts sensitive data, such as credit card details, to protect against fraud and unauthorized access. It also provides various payment options, such as credit cards, digital wallets, and bank transfers, to cater to different customer preferences. With a checkout gateway, businesses can streamline their checkout process, enhance customer satisfaction, and boost sales.
