When the device is idle (i.e., No input device is being utilized), PCDemo displays a slide
show of images. In the most general case, when input is received from any input device
(internal bar code scanner, magnetic stripe reader, pushbuttons, etc...), the data lookup will
be performed with the host server and a lookup screen will be shown containing the server
response. If the server responds with a lookup failure, an error screen can be displayed.
After a given amount of time, PCDemo will return to the slide show loop. This functionality
can be extended through server side scripting and modifications to the runtime
application and source code of PCDemo.
