Arago Card Reader is a daemon that polls a connected NFC-reader for tags, and broadcasts these over a WebSocket. It is inspired by a similar project by Inter-Actief.

• Runs on any platform supported by libnfc and Qt, notably Linux and Windows
• Supports TLS on the websocket server
• Supports multiple parallel connections to the server

Arago Card Reader reads a arago-card-reader.ini configuration file from the same directory as the executable is placed in. It accepts the following settings:

• port: The port to listen on
• tls: Whether to enable or disable TLS (true/false)
• certificate: Path to a PEM-encoded TLS certificate
• key: Path to a PEM-encoded private key

• device: libnfc connection string for the NFC reader to use

Arago Card Reader announces each scanned card in a JSON-encoded format on the websocket, with messages like these:

{"atqa":"1234", "uid":"567890ab", "sak":"cd"}

The ATQA, UID and SAK are hexadecimal encoded.
