What Is a Digital Wallet?
A digital wallet is an app or online service that holds payment information in electronic form. Instead of handing over a physical credit card or cash, a person selects a stored card or bank account inside the wallet and approves the payment, usually with a passcode, fingerprint or face scan. Well-known examples include Apple Pay, Google Wallet and PayPal, and many banks and retailers offer their own wallets. Some wallets also hold loyalty cards, tickets or digital identification.
How It Works
When a card is added, the wallet often does not store the actual card number. Instead, the card issuer or network replaces it with a unique code called a token, and the token is used for transactions. This process, known as tokenization, is designed to limit the exposure of the original card details if a merchant's systems are breached. At checkout, the wallet sends the token along with an authorization. Many wallets work with contactless payment terminals using near-field communication, which lets a user tap a phone or watch at a reader instead of inserting a card.
Digital Wallets in Cryptocurrency
The phrase also appears in cryptocurrency, where a crypto wallet stores the private keys that control digital coins. These tools serve a different purpose. A payment wallet sends instructions through a bank or card network that moves money on the user's behalf, while a crypto wallet's holder controls the keys directly and is responsible for keeping them safe.
Why It Matters
Digital wallets have become a common way to pay in stores and online, and they reduce the need to carry physical cards. Wallet providers rely on payment processor infrastructure to complete transactions, so their fees and transaction volumes are tied to broader payment systems. Wallets typically depend on device passcodes and biometric locks for security, and many providers allow a lost device's cards to be suspended remotely.
