# Payment Wallet Attestation credential schema
## When to use
Use this skill when you issue or ask for a **Payment Wallet Attestation**. The
registry titles the credential **Payment Authenticator (v2)**. It attests one
payment instrument that the wallet holds: the card scheme, the currency, the
issuer identification number, and the truncated card and reference numbers. The
credential never carries the full card number.
The credential is also the input of the transaction data validation operation of
the OpenID4VC API, which takes a `paymentWalletAttestation` field.
The registry publishes this schema in **one format only: `dc+sd-jwt`** (SD-JWT
VC). The metadata sets `isSdJwt` to `true`, and `isJwt` and `isMsoMdoc` to
`false`. There is no JWT form and no mdoc form of this schema in the registry.
This page describes registry version **2025.3.1**, the latest version of the
template.
