# NFC Tag Operation

## Advanced Protection for Pro Users <a href="#advanced-protection-for-pro-users" id="advanced-protection-for-pro-users"></a>

**Advanced Protection** lets you export your account to an NFC tag and turn it into a **Cold NFC Wallet**.

After the export is completed, the private key is encrypted, written to the NFC tag, and removed from this device. This helps reduce the risk of exposing your private key on your phone.

This feature is recommended for users who want stronger wallet protection and understand how to safely store backup files and NFC tags.

## Before You Start <a href="#before-you-start" id="before-you-start"></a>

Prepare:

* A blank NFC tag
* A supported tag type, such as **NTAG215** or **NTAG216**
* A safe place to store your backup JSON file
* A secure PIN/password for the NFC wallet

Important:

Do not lose your NFC tag, PIN/password, or backup JSON file. If you lose access to them, KEYRING PRO may not be able to help you recover the wallet.

## How to Export Account to NFC Tag <a href="#how-to-export-account-to-nfc-tag" id="how-to-export-account-to-nfc-tag"></a>

1. Go to **Account detail**.
2. Tap **Advanced protection for pro users**.
3. Open **Cold NFC Wallet**.
4. Tap **Export**.
5. Select **Export to NFC Tag**.
6. Scan your blank NFC tag.
7. Set a PIN/password to protect the NFC wallet.
8. Enter the PIN/password again to confirm.
9. Save the backup **JSON file** to a safe location.
10. Wait until the success message appears.

After the process is completed, your private key will be encrypted and stored in the NFC tag.

#### About the Backup JSON File

The JSON file works as an authentication backup file.

You need this file if you want to restore or use the wallet later, so keep it somewhere safe. Do not share it with anyone.

#### Important Note

This feature does not create a new wallet. It exports the current account’s private key to an NFC tag for stronger protection.

Only continue if you understand how to safely manage your NFC tag, PIN/password, and backup JSON file.

## NFC Tag Operation <a href="#nfc-tag-operation" id="nfc-tag-operation"></a>

**NFC Tag Operation** lets you manage the wallet data stored in your NFC tag.

You can use this page to:

* View the private key from an NFC tag
* Copy an NFC tag to another NFC tag as a backup
* Erase an NFC tag so it can be reused

#### Important Note

Your NFC tag may contain important wallet access information. Keep it safe and do not share it with others.

Before using **Show private key**, **Copy NFC Tag**, or **Erase NFC Tag**, make sure you understand what you are doing. If you lose your private key or backup, KEYRING PRO cannot recover your wallet for you.

#### Note

Do not share your private key with anyone. Anyone with your private key can access your assets.

KEYRING PRO does not allow copying or taking screenshots on the private key page. If you need to save it, write it down on paper and store it in a safe place.

1. Go to **NFC Tag Operation**.
2. Select **Copy NFC Tag**.
3. Tap **Read**.
4. Hold your device near the original NFC tag.

7. Wait until the success message appears.

After copying, the new NFC tag can be used as a backup of the original NFC tag.

#### Note

Use an empty supported NFC tag, such as **NTAG215**.

## Erase NFC Tag <a href="#erase-nfc-tag" id="erase-nfc-tag"></a>

Use this when you want to delete the data inside an NFC tag and reuse it.
