NFCGate

An NFC research toolkit application for Android

NFCGate is an Android application meant to capture, analyze, or modify NFC traffic. It can be used as a researching tool to reverse engineer protocols or assess the security of protocols against traffic modifications.

On-device capture: Captures NFC traffic sent and received by other applications running on the
device.

Relay: Relays NFC traffic between two devices
using a server. One device operates as a "reader" reading an
NFC tag, the other device emulates an NFC tag using the Host Card Emulation (HCE).

Replay: Replays previously captured NFC traffic in either "reader" or "tag" mode.

Clone: Clones the initial tag information (e.g. ID).
