# PN532Killer Documentation

Setup, firmware, operating modes, software, troubleshooting, and command reference for PN532Killer.

PN532Killer is a multi-protocol RFID development tool that combines a PN532-compatible reader interface with tag emulation and traffic-capture workflows. The open-source [PN532 CLI](https://github.com/whywilson/pn532-python) is the primary interface used throughout this documentation. It auto-detects both standard PN532 hardware and PN532Killer, then exposes the commands supported by the connected device.

Use this documentation to set up the hardware, update its firmware, choose a working mode, connect supported software, and resolve common problems.

## Start here

* New device: install the [PN532 CLI](/pn532killer/software/python-cli.md), then follow the [Quickstart](/pn532killer/getting-started/quickstart.md).
* Learn what the hardware supports: read [Product overview](/pn532killer/getting-started/overview.md) and [Compatibility](/pn532killer/reference/compatibility.md).
* Update an existing device: see [Firmware update](/pn532killer/getting-started/firmware-update.md).
* Find an exact command: open the [PN532 CLI command reference](/pn532killer/reference/command-reference.md).
* Use a graphical or compatibility tool: choose the [Windows tool](/pn532killer/software/windows-tool.md) or [libnfc](/pn532killer/software/libnfc.md).
* Solve a problem: open [Troubleshooting](/pn532killer/troubleshooting.md).

{% hint style="warning" %}
Use PN532Killer only with tags, systems, and readers that you own or are explicitly authorized to test. Capturing credentials or cloning access tokens without permission may be illegal.
