Proxmark3 is a hardware tool and software suite for reading, analyzing, and interacting with RFID and NFC tags across multiple protocols and frequencies.
The Proxmark3 addresses the need for a comprehensive RFID analysis platform by providing both firmware and client software that communicate with the physical device to perform tag identification, cloning, simulation, and penetration testing. The tool supports a wide range of RFID standards including ISO14443A and B, ISO15693, Mifare, iClass, HiTag2, and 125kHz protocols. Users interact with the device through command-line interfaces and can automate workflows using Python and Lua scripting capabilities.
The tool suits anyone conducting RFID security assessments, reverse engineering contactless cards, or developing RFID-based systems. The project is positioned as the standard tool for RFID analysis in the enthusiast and professional security communities.
The project maintains active continuous integration across macOS, Ubuntu, and Windows platforms, ensuring builds remain functional across major operating systems. Code quality is tracked through static analysis. The repository accepts contributions from multiple developers working on protocol implementations, scripting interfaces, and device support across different Proxmark hardware variants including the RDV4 and newer Proxmark5 platforms.
