Default Behavior

Smart Card is a Win32 service. In Windows 8 it is disabled and therefore it won't start under any conditions. When the Smart Card service is started, it runs as NT AUTHORITY\LocalService in a process of svchost.exe, sharing it with other services. If Smart Card fails to start, the error details are added to Windows 8 error log. When the operating system startup is complete, the user is being notified that the SCardSvr service hasn't been started.

Dependencies

Smart Card can't start, if the Windows Driver Foundation - User-mode Driver Framework service is disabled or not available.

The SCardSvr service is using the SCardSvr.dll file that is located in the %WinDir%\System32 folder. If the file is corrupted or deleted, you can put it back in there.
