ABSTRACT:
An electronic postage meter includes two non-volatile memories. One of the non-volatile memories is utilized for storing in historical sequence in respective registers the transaction information for each of a predetermined number of transactions which have occurred prior to the last transaction. This memory is accessed at the time of each transaction. The real-time transaction information may be sequentially written over the earliest information in the registers. The other non-volatile memory stores cumulative data upon power-down.
