Abstract

In a method and an arrangement for increasing the throughput of mail when franking with a security imprint, the editing of the print image data is undertaken by a postage meter machine processor, and the calculation of the security code is undertaken by a separate security module while the print image data are being edited. A high system clock performance is achieved by interleaving of the two calculation tasks.
