摘要:
A postage metering system includes a plurality of computers operatively connected as part of a computer network and operating as client computers on the computer network. At least one postal security device (PSD) is coupled to at least one of the client computers (local client computer). The PSD includes unique identification the ability to store postal value and generate digital signatures. The client computers function as a postage metering network wherein a client computer other than the local client computer (remote client computer) requests evidence of postage payment from the PSD for concluding a postage metering transaction. The local client computer functions as a meter server and the remote client computer functions as a meter client on the postage metering network. The remote client computer initiates a postage metering transaction in the PSD by sending a request for evidence of postage payment to the local client computer. The local client computer sends the request for the evidence of postage payment to the PSD, receives transaction information from the PSD and sends the evidence of payment to the remote client computer for subsequent printing.

摘要:
A postage metering system includes a plurality of printer modules connected as part of a network and operating as clients on the network. Postal security devices (PSDs) are coupled the clients. Each PSD is local to the coupled client functioning as a host to the PSD and remote to the other of the plurality of clients. The PSD includes unique identification, postal value storage and a digital signature generator. The clients function as a postage metering network wherein a client requests evidence of postage payment from a remote PSD for concluding postage metering transactions. Each of the clients determines which of the remote PSDs are available for metering transactions on the network by broadcast messages and requests. In one embodiment, a broadcast request for the identity of remote PSDs whose host is logged onto the network is sent over the network by a client when the client logs onto the network. Additional broadcast requests are periodically sent over the network by the client to other clients logged onto the network. Broadcast messages indicating the unique identification of the PSD coupled to a host are sent over the network by the host when the host logs onto the network. Additional broadcast messages are sent periodically over the network by the host. Another broadcast message indicating that a PSD is no longer available is sent over the network by the host when it logs off the network. In alternate embodiments a network server controls broadcast requests and messages.
摘要:
A postage metering system includes a plurality of printer modules operatively connected as part of a network and operating as client printer modules on the network. A postal security device (PSD) is coupled directly to a local one of the client printer modules. The PSD includes unique identification, postal value storage and a digital signature generator. The client printer modules function as a postage metering network wherein a one of the client printer modules remote to the PSD requests evidence of postage payment from the PSD through the local client printer module for concluding postage metering transactions. The local client printer module function as a stand-alone meter when requests for evidence of postage payment from the PSD are initiated at the local client printer module. The local client printer module initiates local requests for evidence of postage payment to be printed at the local client printer modules and receives remote requests for evidence of postage payment from the remote client printer modules. The remote requests include identification of the remote client printer modules. The local client printer module sends each request for evidence of postage payment to the PSD and receives from the PSD the evidence of postage payment including a digital signature corresponding to each request for evidence of postage payment;. The local client printer module sends the evidence of postage payment to the remote client printer modules in response to the remote request, and prints the evidence of postage payment in response to the local request.

A cost-effective motion control system communication architecture is provided that supports a centralized control node, distributed control nodes, and smart I/O peripheral control nodes. Networks designed using this architecture, which employs a serial bus, may be readily modified or expanded. The architecture supports both real-time highly periodic communications and event-driven peer-to-peer communications.

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.

A method of issuing digital tokens in a open system meter includes the steps of sending a request for digital tokens and predetermined postal information, including addressee information, from a host processor to a vault that is operatively coupled to the host processor; calculating in the vault in response to the request for tokens at least one digital token using the predetermined postal information; debiting postal funds in the vault; issuing the digital token to the host processor; and storing the digital token and the predetermined postal information as a transaction record in the host processor for subsequent generation and printing of an indicia. The method further includes the steps of generating in the host processor an indicia comprising a graphical image of the digital token and the predetermined postal information and storing the indicia in the host processor; and printing the indicia on a mailpiece when requested.

摘要:
A transaction evidencing system includes a plurality of computer systems operatively configured to form a network with one of the computer systems functioning as a server and the remaining computer systems functioning as clients. Each of the computer systems includes a processor, memory and storage media. At least some of the storage means includes non-metering application programs that are selectively run on the client computer systems. An unsecured printer is operatively coupled to at least one of the computer systems for printing in accordance with the non-metering application programs. A portable vault card, which is removably coupled to the server computer system, includes digital token generation and transaction accounting processing. The client computer systems issue requests for digital tokens to the server computer system in response to requests for indicia from the non-metering application programs. The requests for digital tokens include predetermined information required by the token generation processing. The server computer system communicates with the vault card when the vault card is coupled to the server computer system, sending the requests for digital tokens to the vault card and receiving from the vault card the generated digital tokens. The server computer system sends each digital token to the client computer system that requested the digital token. The requesting client computer system generates an indicia bitmap from the digital token. The server computer system receives from the vault a transaction record that includes the digital token and the predetermined information and stores the transaction record in its storage media.
