# Cardholder verification flow

Use this flow to increase a digital card assurance level after **Tokenization**.

The **Token requestor** initiates the flow.

The payment network **TSP** performs **ID\&V** with the **End User**.

### High-level flow

1. The Token requestor requests cardholder verification for a digital card.
2. The payment network **TSP** runs an **ID\&V** method with the **End User**.
3. If verification succeeds, the TSP updates the assurance method.

### Result of a successful verification

* The payment network **TSP** updates the assurance method (assurance level) linked to the digital card.
* Updated signals can be included in authorization requests.

{% hint style="info" %}
This is a post-Tokenization flow.

It is different from Tokenization **step-up authentication**.

Step-up happens before digital card activation.

## 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.payments.thalescloud.io/tokenization/implement-tokenization/post-tokenization-requests/update-the-digital-card-assurance-method-e-commerce-only/cardholder-verification-flow.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.
