125 kHz RFID
Flipper Zero supports low-frequency (LF) radio frequency identification (RFID) technology that is implemented in access control systems, animal chips, and supply chain tracking systems. Unlike NFC cards, LF RFID cards usually do not provide high levels of security. This technology comes in many form-factors, such as plastic cards, key fobs, tags, wristbands, and animal microchips. Flipper Zero has a low-frequency RFID module capable of reading, saving, emulating, and writing LF RFID cards.
You can access the 125 kHz RFID application from the Main Menu. In the application, you can read, save, emulate, write, and generate new LF RFID cards.
Flipper Zero has a built-in RFID support with a low-frequency antenna located at the back of Flipper Zero. The STM32WB55 microcontroller unit is used for the 125 kHz RFID functionality.
The low-frequency 125 kHz antenna is placed on the Dual Band RFID antenna next to the high-frequency 13.56 MHz antenna.
