A local postage security device (PSD) is coupled to a first one of the client modules and a remote PSD is coupled to a second one of the client modules. The local and remote PSDs include respectively first and second unique identification, postal value storage and digital signature generator. The first client module is connected to a remote data center that includes third unique identification, third postal value storage and a third digital signature generator. The first client module selectively requests one of a first evidence of postage payment from the local PSD, a second, evidence of postage payment from the remote PSD and a third evidence of postage payment from the data center.
