| | | Python script sends the same sequence of commands the Windows driver does. The traffic was sniffed using USBPcap and Wireshark (kudos to [~jkramarz](https://github.com/jkramarz) for that). |

| | | The communication protocol is based on NCI (NFC Controller Interface). Unfortunately the specs are not freely available and some proprietary extensions are used. libnfc-nci and kernel sources were used to decode some structs. |
