    • 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.
    • 本申请描述了用于在远程数据中心和本地设备之间可靠地传送诸如虚拟邮票的价值信息的系统和方法。 在至少某个持续时间内唯一的标识符被分配给每个虚拟邮票,使得该标识符与本地虚拟印模设备中的特定索引存储器位置或记录存储位置相关联。 本地打印设备仅允许使用安全状态标志的单个使用虚拟印记。 传输协议提供远程数据中心和本地打印设备之间虚拟邮票的可靠传送,该容器可以重新发送请求,不限于串行传输,也不需要端到端的确认。
