  • Franking system user interface
    Patent number: 7100121
    Abstract: A franking machine control panel and its associated method provide users with touch screen displays in which the main screens contain history tabs. When a history tab is pressed, the display reverts to the previous status of the category of interest, and allows the user to make changes if desired. In the preferred embodiment, the history tabs allow users to view and modify information which is mandatory to the franking process, such as the mail class and postage rates. Another aspect of the present invention allows the user to configure the more actively used buttons of touch screen on one side or the other, depending on the dominant side of the user's body.
