KIXShell
The KIXShell (also called KI/XFS Shell) component provides a secure environment to run selfservice applications. In this case the usual OS-desktop is replaced and the application mode is supervised therefore everytime all neccessary components are running and only one application is visible in the foreground. If an application is terminating itself unexpectedly it'll be restarted or the terminal will be rebooted. If problems are going on the KIXShell will take control and display an out-of-order screen.
Additional some operating-system-specific tasks are provided that can't be implemented in Java:
- user inactive monitor: an application will get a message if no display or keyboard entries are made for a certain time.
- simulating keyboard entries: the hardware control simulates e.g. pinpad entries as usual keyboard entries for windows applications.
- reboot the selfservice device.
- create sound effects on the pc-speaker (or sound adapter)
- set and read system time
- read free and total disc space on harddiscs
To enable to switch between different applications on a terminal, the KI/XFS Shell supports various operating modes. It is defined in the configuration document of the KIXShell, how each mode can be started and terminated. Thus the KIXShell knows which applications must be supervised and how switching is possible between the different modes.
In order that this concept is not restricted on certain case, user defined modes can be created, which are identified definitely by a certain string. On a XFS based terminal e.g. the modes of the operator-switch sensor can be used as operating mode names, so called "run", "maintainance" and "supervisor". In this case a mode switch can be triggered by a XFS application to an API of the KIXShell in consequence of an operator-switch event .
KIXShell is installed on more than 20,000 self-service units (ATMs, Cash-In-units, statement printers) in Austria and Germany.
