## What it is
NFCGate is an Android application for capturing, analyzing, modifying, relaying, replaying, and cloning NFC traffic. It is a security research toolkit for reverse engineering NFC protocols and assessing their resistance to traffic manipulation.

## Use cases
- capture NFC traffic from apps on my Android device
- relay NFC traffic between two phones
- replay captured NFC tag traffic
- clone an NFC tag's ID
- export NFC captures to Wireshark via pcapng
- reverse engineer an NFC protocol
- test NFC protocol security against relay attacks

## When to choose
- you need to capture, relay, replay, or clone NFC traffic on Android for security research
- you want pcapng exports analyzable in Wireshark
- you have a rooted/Xposed-capable device and NFC hardware

## When to avoid
- you need a cross-platform or desktop NFC analysis tool
- your device lacks NFC, HCE support, or an Xposed-compatible hooking framework
- you want a turnkey tool without root/hooking setup
