NFCGate

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.
