# Edit Card Details

## Change 3DS Mobile Number

For some online purchases, 3D Secure verification is required to approve your transactions. You will receive an SMS with verification code on the phone number you registered.

You can change this phone number in the "Card Details" modal. Click on the Pen icon next to 3DS Mobile to change your phone number

## Block Card Transactions

If your card is stolen or for whatever reasons you want to freeze all card transactions, you can do it in the Card Details. Click on "Block My Card" button and click "Confirm" to block all card transactions. You can repeat the same steps if you want to unblock your card.

## 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.fina.cash/fina-card/features/edit-card-details.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.
