Digital Payment Systems
Digital payment systems are platforms and technologies that enable electronic transactions for goods, services, or money transfers without physical cash. They include online payment gateways, mobile wallets, peer-to-peer (P2P) apps, and cryptocurrency exchanges, facilitating secure and instant financial operations over the internet or mobile networks. These systems rely on encryption, APIs, and compliance frameworks to ensure data security and regulatory adherence.
Developers should learn digital payment systems when building e-commerce platforms, fintech applications, or any service requiring online transactions, as they provide essential infrastructure for processing payments securely and efficiently. This skill is crucial for roles in financial technology, retail tech, or SaaS products that handle subscriptions, in-app purchases, or cross-border payments, ensuring compliance with standards like PCI DSS and reducing fraud risks.
