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.

Notice: This application was developed for security research purposes by students of the Secure Mobile Networking Lab at TU Darmstadt. Please do not use this application for malicious purposes.

Features:

On-device capture: Captures NFC traffic sent and received by other applications running on the device. Relay: Relays NFC traffic between two devices. 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. Requirements for specific modes:

NFC support Android 4.4+ (API level 19+) Xposed: On-device capture, relay tag mode, replay tag mode, clone mode. ARMv8-A, ARMv7: Relay tag mode, replay tag mode, clone mode. HCE: Relay tag mode, replay tag mode, clone mode. Compatibility:

NFCGate provides an in-app status check. For further notes on compatibility see the compatibility document
