ABSTRACT:
The present application describes systems and methods for reliable transfer of information of value such as virtual postage stamps between a remote data center and a local device. An identifier that is unique over at least some time duration is assigned to each virtual postage stamp such that the identifier is associated with a specific index memory location or record storage location in the local virtual stamp-printing device. The local printing device permits only a single use of a virtual stamp using a secure state flag. The transfer protocol provides reliable transfer of virtual stamps between the remote data center and the local printing device that accommodates resend requests, that is not limited to serial transfer and that does not require end-to-end acknowledgements.
