Abstract
A franking machine is provided with receiver means to receive positional signals from a global positioning system. The franking machine may be operated to print positional data as part of a franking impression printed on mail items whereby the postal authority is enabled by inspection of mail items to determine that the franking machine is being used at its authorised location. The franking machine may be arranged to be inhibited from operation if not located at its authorised location. The positional signals may be utilised to correct variation in output of a weighscale due to gravitational variation.
