What is Flipper Zero

Flipper Zero is a tiny piece of hardware with a curious personality of a cyber-dolphin. It can interact with digital systems in real life and grow while you use it. Explore any kind of access control system, RFID, radio protocols, and debug hardware using GPIO pins.

Low-frequency proximity cards

This type of card is widely used in old access control systems around the world. It's pretty dumb, stores only an N-byte ID and has no authentication mechanism, allowing it to be read, cloned and emulated by anyone. A 125 kHz antenna is located on the bottom of Flipper Zero - it can read low-frequency proximity cards and save them to memory to emulate later.

You can also emulate cards by entering their IDs manually.

Moreover, Flipper Zero owners can share card IDs remotely with other Flipper Zero users.

NFC

High-frequency proximity cards

Flipper Zero has a built-in NFC module (13.56 MHz).

Along with the 125 kHz RFID module, it turns Flipper Zero into an ultimate RFID device operating in both low-frequency (LF) and high-frequency (HF) ranges.

The NFC module supports all the major standards.

It works pretty much the same as the 125 kHz module, allowing you to interact with NFC-enabled devices - read, write and emulate HF tags.
