# Reset the NFC Wallet SDK

## Overview

Resetting the NFC Wallet SDK deletes all data stored by the SDK on the device.

This includes items managed by the SDK, such as digital cards and payment credentials.

{% hint style="warning" %}
Reset is local only. It does not call any server APIs. Any tokens that already exist on the server side are not deleted.

After you reinitialize the SDK, the wallet ID changes. Tokens created before the reset can become orphan tokens on the server side. They may be deleted when you run Tokenization for a new card (in process called **tokens cleanup**).
{% endhint %}

After a reset, the SDK assigns a new wallet ID at the next initialization. See [Retrieve the wallet ID](/nfc-wallet-sdk-android/get-started/configuration/4.-initialize-the-nfc-wallet-sdk.md#retrieving-the-wallet-id).

{% hint style="info" %}
After you reset the NFC Wallet SDK, run [Enroll wallet](/nfc-wallet-sdk-android/implement-nfc-wallet/enroll-wallet.md) before any new Tokenization.
{% endhint %}

## SDK integration

Call `SDKDataController.INSTANCE.wipeAll(appCcontext)` to delete all data stored by the NFC Wallet SDK.

```java
SDKDataController.INSTANCE.wipeAll(appContext);
```

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

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.payments.thalescloud.io/nfc-wallet-sdk-android/additional-features/reset-the-nfc-wallet-sdk.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

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.
