ABSTRACT:
A stored value transaction system has a plurality of value storing transfer devices. First and second stored value transaction networks each include at least one local value storing device, at least one consolidation device, and at least one network settlement device. An internetwork value information transfer device coupled to the first and second stored value transaction networks transfers value information between the internetwork value information transfer device and the first and second stored value networks. Cryptographic verifiers in each of the networks and in the internetwork value transfer device make independent secure transaction determinations and permit transfers according to the determinations. The value information transferred from the consolidation device to the settlement device may be a summary of the information received by the consolidation device. The network settlement device performs settlement based upon the information summary. The transfer devices within the first and second networks have common cryptographic keys.
