An unsecured postage applying system wherein the printer 30 and metering unit 14 are separated from one another by an unsecured link. The printer may be of any "off-the-shelf" type that is capable of printing alpha numerics or bar codes. More than one printer can be connected to a single metering unit to provide a network of printers accommodated by the one metering unit, Figure 3. The secure metering unit 14 encloses accounting and encryption modules 24,22; an encryption message is generated in the metering unit, and is transmitted for printing on the mail piece together with the postage value, Figure 2, for subsequent verification in the postal sorting system. The printer 30 is limited to metering unit 14 through user computer 28, or forms part of a word-processor, Figure 3. <IMAGE> |
