Payment Gateway
A payment gateway is a technology platform that securely processes online transactions by transmitting payment data between merchants, customers, and financial institutions. It acts as an intermediary that authorizes credit card or digital payments for e-commerce websites, mobile apps, and other online services. Payment gateways handle encryption, fraud detection, and compliance with standards like PCI DSS to ensure secure and reliable payment processing.
Developers should learn about payment gateways when building applications that require online payment functionality, such as e-commerce platforms, subscription services, or donation systems. They are essential for securely handling sensitive financial data, reducing fraud risk, and ensuring compliance with industry regulations. Knowledge of payment gateways is crucial for integrating payment processing into websites, mobile apps, or APIs, enabling businesses to accept payments from customers globally.
