<p>A value printing system, such as a postage metering system, is disclosed wherein the secure meter accounting registers are removably coupled to the meter. The registers are maintained redundantly within two dissimilar types of non-volatile memory devices, the devices being enclosed within an accounting vault. The vault may have the form of a small enclosure which may have the dimensions of a typical credit card. The invention provides for the local recharging of the meter postal funds by the removal of a first vault having an indication of depleted postal funds and the insertion of a second vault having an indication of available funds. In addition, by maintaining the meter accounting registers external to the system, the invention provides for a postage metering system wherein the necessity of the complex mechanical security devices of the prior art is eliminated.</p> |
