Digital wallet token-based payment flow
How a digital wallet pays without exposing the real card number.
The user taps their wallet phone near the merchant's NFC terminal, sending a one-time encrypted token. The token is passed to the wallet provider's server, which forwards a payment request to the card-issuing bank. The issuer approves or declines, and the merchant receives the result — without ever seeing the real card number.
