A digital wallet (or e-wallet) is an app that stores your payment cards, bank accounts, and cash digitally on your phone or computer. Instead of pulling out a physical card or cash, you tap your phone, scan a QR code, or click a button to pay — instantly and securely.
Popular digital wallets: Apple Pay, Google Pay, Samsung Pay, PayPal, Paytm, PhonePe, and GPay (India). China's Alipay and WeChat Pay dominate the Asian market with over 1 billion users each. India's UPI-based wallets processed Rs 20 lakh crore monthly by 2024.
Digital wallets use tokenization and encryption to protect your data — your actual card number is never shared with merchants. The global digital wallet market is projected to reach $16 trillion in transaction value by 2028. In many developing countries, digital wallets are leapfrogging traditional banking entirely.
