¹ Requires NXP NFC chip — most Samsung and some other Android devices use non-NXP controllers and cannot read MIFARE Classic. ² PC/SC readers only. PN533-based USB readers do not support NFC-V. ³ Ultralight variant only. ⁴ DESFire variant only. 🔒 Requires encryption keys — see Cards Requiring Keys.

Cards Requiring Keys

Some MIFARE Classic cards require encryption keys to read. You can obtain keys using a Flipper Zero, Proxmark3, or MFOC. These include:

• Bilhete Único
• Charlie Card
• EasyCard (older MIFARE Classic variant)
• OV-chipkaart
• Oyster
• And most other MIFARE Classic-based cards

Flipper Zero Integration

FareBot supports connecting to a Flipper Zero to browse and import NFC card dumps and MIFARE Classic key dictionaries.

Platform	USB	Bluetooth
Android	Yes	Yes
iOS	—	Yes
macOS	Yes	—
Web	Yes	Yes

From the home screen menu, tap Flipper Zero to connect via USB serial or Bluetooth Low Energy, browse the /ext/nfc file system, select card dump files (.nfc), and import them into your card history. You can also import the Flipper user key dictionary (mf_classic_dict_user.nfc) into the app's global key store, which is used as a fallback when reading MIFARE Classic cards.
