Microsoft Windows Lockscreen Integration With Smart Card
RjR developed Qsync to streamline the process and to improve user experience.
Qsync hooks Microsoft Graphical Identification and Authentication (GINA). GINA is a Dynamic Link Library (DLL) loaded by Windows Login executable. GINA executes all identification and authentication associations and is responsible for recognizing the key sequence of Control + Alt + Delete that begins the logging in or out process of a workstation.
