How can I make sure that nobody can use my Passcards when I need to step out?
Make RoboForm forget the cached Master Password by clicking Logoff on the toolbar. You may also use Auto-Logoff option that makes RoboForm purge the cached Master Password after a period of inactivity. When the “Logoff” button is enabled, it means that RoboForm has your Master Password cached in memory. When this button is disabled then RoboForm has no passwords cached.
