# How to use credential with verifier

Some services require you to share specific information from your credentials.

1. Scan the **Verifier's** QR code in the wallet.
2. The wallet will determine what data the verifier is requesting (for example, proof of having a particular ticket type).
3. If you have a matching credential:
   * The wallet displays a list of suitable credentials.
   * Choose which credential you want to present.
4. Confirm the sharing: the wallet creates a *Verifiable Presentation*, signs it cryptographically, and sends it to the verifier.
5. The verifier checks the signature and validates the credential.

## Logging in with the Wallet

Some services may only require you to prove control of your DID (a simple login flow). In this case:

* After scanning the verifier's QR code, you confirm the **proof of control** with your DID (via cryptographic signature).
* No specific credential is required, and the process completes once you sign.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.empe.io/user-guide/00_introduction/05_how_to_use_credential_with_verifier.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
