DCQL query: Payment Wallet Attestation

When to use

Use this template when a person pays and the wallet must show which funding source pays. The query asks for seven claims inside one fundingSource object: the alias identifier, the currency, the issuer identification number (IIN), the last four digits of the card number, the card scheme, the type, and the icon.

Typical uses are strong customer authentication (SCA) at checkout, card selection in a payment sheet, and payment confirmation with a wallet.

The template never asks for the full card number. panLastFour and iin are enough to show the card to the payer and to route the payment.
