## What it is
ChameleonMini is a freely programmable, portable NFC device that can emulate and clone contactless smartcards, read RFID tags, and sniff/log RF data. This repository contains the firmware (C), hardware schematics, drivers, and a Python configuration tool for the device.

## Use cases
- emulate and clone contactless NFC smartcards
- sniff and log ISO14443 RFID traffic
- security analysis of contactless card systems
- test NFC readers with emulated Mifare cards
- flash and configure ChameleonMini RevG firmware

## When to choose
- you own official ChameleonMini RevG hardware and need firmware or tooling
- you need a programmable NFC card emulator for security research
- you want open hardware schematics and firmware for RFID emulation

## When to avoid
- you have third-party clone hardware, which is unsupported
- you need a pure software NFC emulator without physical hardware
- you need support for RevE-rebooted hardware or third-party GUIs

## Facets
- artifact type: application
- maturity: active
- function: security, reverse-engineering, embedded
- domain: security, hardware, penetration-testing
- platform: embedded, windows, python, c
- tags: nfc, rfid, smartcard-emulation, mifare, iso14443, firmware, hardware-hacking, sniffer, linux
