Customer Pole Devices (CPD’s) have long been considered merely bells and whistles at the Point of Sale (POS). They were seen as nice to have if extra money allowed, but were often the first item to be eliminated from the POS station when the budget limits were reached. Their main function was to display to customers information that was being displayed elsewhere and the redundancy was what made them seem to be superfluous. Note that they do not always stand on a pole, but sometimes can be incorporated in the EPOS terminal.
