A mobile wallet is a digital application that allows users to store and manage their payment information on their smartphones. It enables users to make purchases, send money, and receive funds without needing physical cash or cards. Popular mobile wallets include Apple Pay, Google Pay, and PayPal. Mobile wallets use secure technology, such as encryption and tokenization, to protect users' financial data. They can also store loyalty cards, coupons, and tickets, making it convenient for users to access various services in one place. Many retailers and online platforms accept mobile wallet payments, enhancing the shopping experience.
