## What it is
The Iceman fork of Proxmark3, the client software for the Proxmark3 RFID analysis device, supporting reading, cloning, simulating, and sniffing a wide range of RFID/NFC tags. It includes extensive commands and Python/Lua scripting for chip identification and penetration testing.

## Use cases
- clone and emulate RFID access cards
- analyze Mifare and iCLASS contactless smartcards
- sniff ISO14443A/B and ISO15693 tag communications
- read and write 125kHz low-frequency tags
- penetration test NFC and RFID systems
- identify unknown RFID chip types
- recover keys from Hitag2 transponders

## When to choose
- you own a Proxmark3 device and want the most feature-rich client firmware and tooling
- you need broad protocol coverage for RFID/NFC security research
- you want scripting support to automate RFID analysis tasks

## When to avoid
- you need a pure software RFID reader without Proxmark3 hardware
- you only need casual NFC tag reading on a phone
- you require a simple GUI-only workflow without command-line usage

## Facets
- artifact type: application
- maturity: active
- function: security, reverse-engineering, cli, developer-tools
- domain: security, hardware, penetration-testing, reverse-engineering
- platform: windows, cli, cross-platform
- tags: rfid, nfc, mifare, proxmark3, contactless-smartcards, hardware-hacking, sniffer, pentesting, linux, macos
