You can read, save, and emulate different types of NFC cards with your Flipper Zero. On this page, you will learn: how to read and emulate NFC cards, the list of supported NFC card, and the algorithm behind the NFC Read function.

Reading process is automatic and doesn't require any manual configuration by the user. For more information about the reading algorithm, see the Reading process flowchart. To read and save NFC card's data, do the following:

1. Go to Main Menu → NFC.
2. Press Read, then apply the card to Flipper Zero's back.

3. When reading is finished, go to More → Save. 4. Name the read card, then press Save.

New types of NFC cards will be added to the list of supported cards. Flipper Zero supports the following NFC cards type A (ISO 14443A):

• MIFARE Classic 1K & 4K — read, save, and emulate a card.
• MIFARE Ultralight and NTAG — read, save, and emulate a card.
• MIFARE DESFire — save unencrypted data and emulate an UID.
• Bank cards (EMV) — read, save, and emulate an UID.
• Unknown cards — read (UID, SAK, ATQA) and emulate an UID.

For NFC cards type B, type F, and type V, Flipper Zero is able to read an UID without saving it.

For MIFARE Classic 1K & 4K cards, Flipper Zero can read and save data stored in sectors. In order to read data stored in sectors, Flipper Zero has to find all 32 keys for 16 sectors (Classic 1K) or 80 keys for 40 sectors (Classic 4K). For that, Flipper Zero uses its own MIFARE Classic Keys dictionary. Users can add their own keys to the dictionary.

For MIFARE Ultralight & NTAG cards, Flipper Zero can read and save stored data. In this type of cards, memory is organized in pages. Flipper Zero reads and saves open pages with data.

For MIFARE DESFire cards, Flipper Zero can read and save stored data. In this type of cards, memory is organized in applications, which have multiple files. Flipper Zero reads and saves unprotected applications and files with data.

Flipper Zero can read and save an UID, SAK, ATQA, and stored data on bank cards.

When Flipper Zero is unable to determine NFC card's type, then only an UID, SAK, and ATQA can be read and saved.

For NFC cards types B, F, and V, Flipper Zero can only read and display an UID without saving it.

Depending on the NFC card type and saved data, Flipper Zero can emulate an entire NFC card or just an UID. To emulate a saved NFC card or an UID, do the following:

1. Go to Main Menu → NFC → Saved.
2. Select the card, then press Emulate.

While emulating, Flipper Zero's indicator starts flashing blue light. Hold Flipper Zero near the reader to transfer data.

The process of reading NFC cards is automatic and doesn't require any manual configuration by the user. While reading, Flipper Zero automatically determines the NFC card type and follows the algorithm below:
