Abstract

A postage meter having facilities for departmental accounting is disclosed. A non-volatile department memory is provided for each department, each department memory storing data relating to a specific department. An additional single non-volatile memory is also provided. During each franking transaction in respect of a department, current data is read from the associated department memory and is written to the additional memory. Current data from the department memory is updated in respect of the transaction and the updated data is written to the department memory. The provision of the single additional memory enables department data in respect of each department to be recovered in the event of a fault occurring during the transaction.
