What is Mobile Wallet?

Quick answer

An app or phone feature that stores payment cards, bank links, or balances so users can pay with their phone.

Mobile Wallet, explained

Mobile wallets let people pay in shops by tapping their phone on a contactless terminal, scanning a QR code, or sending money through an app. Some wallets store digitized versions of existing debit and credit cards, while others hold a balance directly or link to a bank account through systems such as UPI.

Security features typically include tokenization, which replaces the real card number with a substitute for each transaction, and authentication with fingerprints, face recognition, or a PIN. Wallets may also hold boarding passes, event tickets, loyalty cards, and digital IDs. In several countries, mobile wallets and QR payments have become a leading way to pay, reducing reliance on cash.
