Flipper Zero
Portable multi-tool for RFID, NFC, infrared, sub-GHz radio, and BadUSB experimentation.
Technical Architecture & Overview
Flipper Zero is a pocket device with modules for 125 kHz RFID, 13.56 MHz NFC, infrared, and sub-GHz radio; its low-frequency RFID module reads, saves, emulates, and writes cards, and the device can act as a BadUSB keyboard. The firmware is open source, and GPIO pins support hardware debugging and add-on modules.
Targeted Technical Use Cases
Portable assessment and demonstration of access control systems and short-range wireless protocols.
Evaluation & Trade-offs
Core Strengths
- +Many radio capabilities in one portable device.
- +Open source firmware with an active community.
- +Also debugs hardware through its GPIO pins.
Trade-Offs & Limitations
- -Writing NFC cards and 1-Wire keys works only with rewritable media.
- -Sub-GHz transmission is limited to frequencies allowed for civilian use in the device region.
Defensive Security Application
Testing physical access controls and raising awareness of cloneable credential technologies.
