## Health v2 (maintenance only)
Score: 50/100 (v2, computed 2026-09-03T02:20:16.233290+00:00)
- activity 60, release rhythm 8, longevity 100
- inputs: {"age_days": 4553, "days_push": 243, "days_rel": null, "gap_med": null, "n_releases_24m": 0}
- flags: none
- formula: round(0.45*activity + 0.35*rhythm + 0.20*longevity); archived -> min(score, 10)

## Adoption (not part of the score)
Stars 3534, forks 950 (observed 2026-08-28T04:08:09.019074+00:00)

## What it is
The official (now archived) client software, FPGA logic, and design documentation for the Proxmark3, a general-purpose RFID tool that can snoop, read, clone, and emulate low-frequency (125kHz) and high-frequency (13.56MHz) tags. Active development has moved to the RRG/Iceman fork.

## Use cases
- sniff and analyze RFID tag communications
- clone RFID access cards
- emulate 125kHz and 13.56MHz tags
- reverse engineer NFC and RFID protocols
- audit physical access control systems
- read and write RFID tags

## When to choose
- you own a Proxmark3 device and need the original official firmware and client
- you want the historical reference implementation or design documentation for the hardware

## When to avoid
- you want active development, bug fixes, or new tag support - use the RRG/Iceman fork instead
- you need a software-only RFID tool without Proxmark3 hardware

## Facets
- artifact type: cli-tool
- maturity: abandoned
- function: security, reverse-engineering, embedded, cli
- domain: security, hardware, penetration-testing, reverse-engineering
- platform: windows, cli, embedded
- tags: rfid, nfc, hardware-hacking, proxmark3, fpga, archived, linux, macos
