# Payment User Credential (TS12) - credential schema
## When to use
Use this skill when you issue or verify a **Payment User Credential (TS12)**.
The credential identifies the payment service user. It is one of the three SCA
payment credentials in the registry, together with the payment account
credential and the payment card credential.
The metadata sets `isScaCredential` to `true`. The schema supports one format:
SD-JWT VC (`dc+sd-jwt`).
The registry keeps this schema under
`credentialSchemas/claimPathPointer/scaPaymentUser`. Version **2025.7.1** is the latest
version directory, and this skill uses it. The registry publishes the schema
in one format: `dc+sd-jwt`.
## What the claims describe
The registry document holds an **empty `claims` array**. The registry fixes no
claim path pointer for this credential.
This is not a mistake in this skill. Read it as follows.
- The credential exists to bind the payment service user, and the binding comes
from the credential itself, not from a claim.
- Do not invent claim paths. A verifier that reads the registry does not expect
a claim that the registry does not hold.
- If your use case needs a claim, ask the registry maintainers to extend the
schema. Then fetch the source again, because a later version of the template
can add claims.
Check the source-doc URL before each new integration, because an empty schema is
the shape that changes first.
