    • A transaction evidencing system includes a personal computer (PC) comprising a processor, memory and hard drive, with a plurality of non-metering application programs that selectively run on the PC. An unsecured printer is operatively coupled to the PC for printing in accordance with the non-metering application programs. A portable vault card that is removably coupled to the PC is programmed to generate tokens generation and perform transaction accounting. An application interface module in the PC, which interfaces with the non-metering application programs, issues a request for digital tokens in response to requests for indicia from a non-metering application program. A secure communications module in the PC, which securely communicates with the vault card when the vault card is coupled to the PC, sends the request for digital token to the vault card and receives a digital token generated by the vault card. An indicia bitmap generation module generates an indicia bitmap in the PC from the digital token and stores it in memory. The indicia bitmap is accessed by the non-metering application program when a print indicia operation is selected. A transaction capture module in the PC stores on the hard drive a transaction record corresponding to each issued digital token and associated postal data. The application interface module, the secure communications module, the indicia bitmap generation module and the transaction capture module are part of a dynamic link library module in the PC.
    • 交易证明系统包括包括处理器,存储器和硬盘驱动器的个人计算机(PC),其具有选择性地在PC上运行的多个非计量应用程序。 根据非计量应用程序,不安全的打印机可操作地耦合到PC以进行打印。 可拆卸地耦合到PC的便携式存储卡被编程为产生令牌生成并执行事务计费。 与非计费应用程序接口的PC中的应用接口模块响应于来自非计费应用程序的标记的请求而发出数字令牌的请求。 PC中的安全通信模块,当保险库卡耦合到PC时,其与保险库卡安全地通信,将数字令牌的请求发送到保险库卡并接收由保险库卡产生的数字令牌。 标记位图生成模块从数字令牌在PC中生成标记位图并将其存储在存储器中。 当选择打印标记操作时,非计量应用程序访问标记位图。 PC中的交易捕获模块在硬盘驱动器上存储与每个发行的数字令牌和相关联的邮政数据相对应的交易记录。 应用接口模块,安全通信模块,标记位图生成模块和事务捕获模块是PC中动态链接库模块的一部分。
