A payment gateway is an online service that securely processes and authorizes payments between customers and merchants during an e-commerce transaction. It encrypts sensitive information—such as credit or debit card details—to protect customer data and efficiently communicates transaction requests between websites, banks, and payment networks.
Integrating a reliable payment gateway into a website boosts customer trust, enhances checkout security, and reduces payment-related friction. By ensuring smooth, secure, and quick transactions, businesses minimize cart abandonment rates, improve user experience, and ultimately increase conversion rates and revenue.
