Flipper Zero supports NFC technology, which is implemented in public transport smart cards, access cards or tags, digital business cards, and bank cards. These cards have complex protocols and support encryption, authentication, and full-fledged two-way data transfer. Flipper Zero has a built-in 13.56 MHz NFC module which is capable of reading, saving, and emulating NFC cards.

You can access the NFC application from the Main Menu. In the application, you can interact with NFC cards, analyze readers, and generate NFC cards.

• Read — reads and saves NFC card's data such as UID, SAK, ATQA, and stored data.
• Detect Reader — emulates an NFC card to receive authentication keys from logs sent by a reader.
• Saved — lists saved NFC cards, which can be emulated and renamed.
• Extra Actions — additional reading scripts, plugins, keys management, and etc.
• Add Manually — generates new virtual NFC cards by manually entering card's data.

Flipper Zero has a built-in NFC module based on a ST25R3916 NFC chip and a 13.56 MHz high-frequency antenna. The chip is used for high-frequency protocols and responsible for reading and emulation of cards.

The high-frequency 13.56 MHz antenna is placed on the Dual Band RFID antenna next to the low-frequency 125 kHz antenna.
