These numbers can’t be changed. **NFC magic** or **UID rewritable** are special cards that can change their UIDs. That makes magic cards more powerful — they can copy the UID and data of an original card. There are [different generations](https://lab401.com/blogs/academy/know-your-magic-cards) of magic cards. On this page, you’ll learn about supported magic cards and how to write the UID and data from an original card to an NFC magic card. :::Iframe{iframeHeight="0" code="
To use this feature, you need to download the NFC Magic app to your Flipper Zero from Apps.
"} ::: *** # Writing card data Flipper Zero can write data to **Gen1**,** Gen2**, and **Gen4** magic cards, as well as** regular MIFARE Classic®** cards (without rewriting the UID). **Gen1 magic cards** can be configured as the following card type: - MIFARE Classic® 1K **Gen2 magic cards** can be configured as the following card type: - MIFARE Classic® 1K (Compatible Gen 2 card is required) - MIFARE Classic® 4K (Compatible Gen 2 card is required) **Gen4 (Ultimate) magic cards **can be configured as the following card types: - Any MIFARE Classic® - MIFARE Ultralight® EV1 - MIFARE Ultralight® EV2 - NTAG® 203 - NTAG® 213 - NTAG® 215 - NTAG® 216 To copy the original NFC card, you need to write the original UID and data to the NFC magic card by doing the following: ::::WorkflowBlock :::WorkflowBlockItem [Read and save the original card](https://docs.flipper.net/zero/nfc/read). Make sure that your Flipper Zero reads all sectors or pages of the original card! ::: :::WorkflowBlockItem Go to **Main Menu** **-> Apps -> NFC -> NFC Magic**. ::: :::WorkflowBlockItem Check if you have a compatible Gen1, Gen2, or Gen4 magic card by using the **Check Magic Tag** option and holding the magic card near the back of your Flipper Zero. *or* If you have a password-protected Gen4 card, go to **Gen4 Actions -> Auth with password** to enter the password manually. Then use the **Check Magic Tag** option. ![](https://api.archbee.com/api/optimize/3GUDYkC5JgUWgo6RW8piO-PYPg8lTp6xekgfufC9sKD-20241107-112912.png "Hold the card near the back of your Flipper Zero") ::: :::WorkflowBlockItem If the magic card is supported, you’ll see the message below, otherwise your Flipper Zero will keep trying to determine the card type. ![](https://api.archbee.com/api/optimize/3StCFqarJkJQZV-7N79yY/yYLTTW3EeuKEu5sUJzNc8_magic-cards-apps.jpg "Your Flipper Zero will let you know if you have the magic card") ::: :::WorkflowBlockItem Go to **More** to see options for this type of magic card. ::: :::WorkflowBlockItem To write the UID and data of the original card, use the **Write **option. ::: :::WorkflowBlockItem Select the original card in the browser and hold the magic card near the back of your Flipper Zero. ::: :::WorkflowBlockItem Once your Flipper Zero writes data to the magic card, you’ll see the message below. ![](https://api.archbee.com/api/optimize/3StCFqarJkJQZV-7N79yY/NOJZtJassRTaSFXSUznfk_magic-cards-apps-1.jpg "The data of the original card is written to the magic card") ::: :::: You can also format the magic card by using the **Wipe** option — the UID will be reset to the default, and data in sectors or pages will be deleted. *** MIFARE and MIFARE Classic are registered trademarks of NXP B.V.
