Carrier management system having accounting registers

摘要

A register system such as a carrier management system has a scale for weighing parcels, and a computer for determining shipping costs of the parcels. The computer has a memory including one or more accounting registers. A user PROM having a unique identification number therein is insertable in the system, and an initialization program stores this number in the system memory. Transactions cannot be accounted unless the numbers in the PROM and memory compare. A further PROM is insertable in the system in order to enable the initialization program.
