USPS allowed considerable experimentation starting in the 1990's. This
resulted in a rich CVP (computer vended postage) area in the US even
though we missed the "Frama" development in other parts of the
the diagram below to get a handle on the many variations based on our
understanding of the US DMM604. We divided postage
meters into three classes: Traditional Postage Meters, PC Postage (CVP) and Vending
Some of the PC Postage and Vending Postage types are similar to Postage Stamps
in that they are undated and can be used at some time in the future. Thus, the Postage
is shown to overlap some of the items. This diagram is still being
discussed (and can be somewhat controversial) and we expect change it. If
you have information please join the MSS Discussion Group.
hope to provide similar diagrams for postage meters from other parts of the
world with the assistance of collectors.
