Thank you kyler.kamyszek this is very interesting, this could be useful as well.  
The other problem is the RFID Reader,  
Can we use an external USB card reader to authenticate into Ignition or the only way is with a cellphone.  
Does it supported any Badge card reader ?

I found this thread which explain well the way to use the badge.

I think I am confused between Badge Auth and NFC scan.
