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).

  • pcapng export of captured NFC traffic, readable by Wireshark.
