Wallet

Add a card

Enroll a card through Yuno’s secure form and keep card details out of Wallet.

Wallet uses Yuno’s hosted enrollment form. Your card number and security code go directly to Yuno, while Wallet stores only the token and safe display details it needs.

Enrollment flow

  1. 1

    In Wallet, open Wallet and select Add a card.

  2. 2

    Wallet creates a short-lived Yuno customer session on the server.

  3. 3

    Yuno’s secure form collects the card details in the browser.

  4. 4

    Yuno returns a vaulted token; Wallet verifies it belongs to your Yuno customer and saves display metadata such as brand and last four digits.

What Wallet stores

Wallet storesThe Yuno vaulted token, brand, last four digits, expiry, fingerprint, and agent-access state.
Wallet does not storeThe card number, CVC, PIN, or Yuno private API credential.

Agent access

A saved card may need a separate provisioning step before it can support future agent payment features. Wallet shows that state on the card. Temporary mock cards never expose, use, or derive from it.
