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).
