The daemon is implemented in `brmdoor_nfc_daemon.py`.
## NFC smartcard API
This project shows how to use libnfc from python to send APDUs to NFC
smartcards. Have a look at `test_nfc.py` for some examples, currently it
shows four interactions with NFC smartcards:
* read NDEF message from token (Mifare Desfire, Yubikey Neo)
* do HMAC-SHA1 authenthication (Yubikey Neo)
* read Track 2 Equivalent Data from Visa
* execute signature for payment on Mastercard
It is much more general in use than to use it as authenthicator to open door.
