A digital wallet is a secure online tool that allows you to store and manage your payment information, such as credit cards and bank accounts, all in one place. Instead of carrying physical cash or cards, you can make purchases using your smartphone or computer. Popular examples of digital wallets include PayPal, Apple Pay, and Google Wallet. These wallets not only make transactions easier but also enhance security by encrypting your data. When you shop online or in stores, you can quickly pay with just a tap or click, making your shopping experience more convenient and efficient.
