Where user privacy is most critical, it is important to know when a user has arrived at the kiosk and also when they have left. KioWare can easily be configured to use a security mat or proximity switch to initiate the user session and more importantly to end a user session, including running an optional logoff script. When a user trips the security mat or proximity switch, KioWare exits attract screen mode, and when the user leaves the security mat or proximity switch, then KioWare runs a logoff script (if one is defined), optionally clears cookies and cache, optionally retracts paper printed but not retrieved, and enters attract screen mode.
