Method of checking daily consumption of postal charges by a postage meter and a postage meter enabling such monitoring to be performed

摘要

In a postage metering system, daily postage usage data is accumulated and stored over a period of time. Periodically the stored accumulated postage usage data is recovered from the postage meter system and noted on a billing form. A certification number is generated from the stored accumulated postage usage data and noted on the billing form. The certification number is then used by a billing authority to verify the correctness of the noted accumulated postage usage data in order to ensure proper billing.
