Digital Wallet
A digital wallet is a software-based system that securely stores users' payment information and passwords for numerous payment methods and websites. It enables users to make electronic transactions quickly and conveniently, often through mobile devices or web interfaces. Digital wallets can store credit/debit cards, loyalty cards, tickets, and cryptocurrencies, facilitating both online and in-person payments.
Developers should learn about digital wallets to build secure payment systems, e-commerce platforms, and fintech applications, as they are essential for modern digital transactions. This skill is crucial when implementing features like one-click payments, mobile app integrations (e.g., Apple Pay, Google Pay), and blockchain-based wallets for cryptocurrencies. It's particularly valuable in industries like retail, banking, and decentralized finance (DeFi) where seamless and secure user experiences are paramount.
