External login architecture SFC
- A hardware-specific application (custom-made) registers hardware signals. The personnel number or badge number is read from these signals.
 - An SFC API call is made to the SFC External Login Web Service; the call includes the personnel or badge number and the name of the terminal.
 - SFC applicatie maintains a net.tcp connection to the web service so SFC can be notified when an external login comes in.
 

Please note: The server and the Windows user logged in on the client (PC) need to be in the same domain.
