Proxmark3 is a general-purpose RFID tool that enables users to snoop, listen to, and emulate radio frequency identification tags across a wide frequency range from Low Frequency (125kHz) to High Frequency (13.56MHz).
The tool addresses the need for hands-on RFID security research and testing by providing both hardware and software components. The device itself is a portable unit roughly the size of a deck of cards, and the repository supplies the firmware, FPGA logic, and complete hardware design documentation needed to understand and potentially build or modify the device. This approach gives researchers direct access to the entire stack from circuit design through software implementation.
Proxmark3 suits security researchers, penetration testers, and hobbyists working with RFID systems who need to analyze tag behavior, test security implementations, or develop custom RFID applications. The project provides schematics, PCB artwork in Gerber format, and a bill of materials, making it possible for experienced electronics builders to assemble units in small quantities. The hardware is also available pre-assembled from multiple distributors worldwide. Prospective users should note that the official repository is no longer actively maintained, with development having moved to a community fork.
The project shows minimal recent development activity, with no ongoing commits or updates to the codebase. Documentation and community resources including a wiki, forum, and Discord server remain available but receive no active updates from the original maintainers. The archived status means users should expect no bug fixes, security patches, or new features from this repository.
