Payment Processing
Payment processing is a technology platform that enables secure electronic transactions between merchants and customers, handling authorization, settlement, and fraud prevention. It involves integrating payment gateways, processors, and merchant accounts to facilitate credit card, digital wallet, and alternative payment methods in e-commerce, mobile apps, and point-of-sale systems.
Developers should learn payment processing when building applications that require monetization, such as e-commerce sites, subscription services, or in-app purchases, to ensure compliance with security standards like PCI DSS and provide a seamless user experience. It is essential for handling sensitive financial data, reducing fraud risks, and supporting global payment methods to expand market reach.
