VSys Kiosk does not need a keyboard; all volunteer interaction can be done via the touchscreen. If you do leave a keyboard attached for volunteers to use, use an older keyboard and glue the Ctrl, Windows, context menu and Alt keys in place. (Don't just remove them, a pen pushed through the key's opening would work just as well as the key itself.) A malicious or simply curious user could use these to exit out of the kiosk software and get full access to the computer it's running on.
