Abstract: A postage printing system enables users to generate postage indicia and print mail pieces at client computers. Upon user determination of a mail piece print failure, a mail metering application on the client computer sends reprint request to an authorizing authority at a remote location. The reprint request includes information identifying an account for printing a postage indicia. A server computer used by the authorizing authority receives the reprint request from a client computer and evaluates the request. When the account is verified and other criteria are satisfied, a reply is sent to the client computer that includes a reprint authorization. Otherwise, a negative reply is sent to the client computer that does not include the reprint authorization. Upon receiving a reprint authorization from the authorizing authority, the client computer prints a replacement mail piece with the postage indicia.

Abstract: A method and system for using a tracking ID to facilitate the refunding of unused postage is provided. Information for a postage transaction, along with the tracking ID and an associated delivery status, is stored. This delivery status is updated when the mail piece carrying the tracking ID is delivered. Unused postage can be confirmed by retrieving the stored postage transaction information and determining from that whether there are duplicative postage transactions. The delivery statuses for the duplicative postage transactions can then be reviewed to determine whether the mail pieces associated with these postage transactions have been delivered. If not, one of the postage transactions may be refunded.

Abstract: A method and system for using an indexing identifier (such as, e.g., a tracking ID or the combination of a postage vendor ID, user account, and piece count) to decrease the size of the postage indicium transmitted to an end user computer, or eliminate transmission of the postage indicium altogether, is provided. When the postage indicium for the end user computer is generated, it is stored, and the indexing identifier, rather than the postage indicium, is transmitted to the end user computer. The indexing identifier is applied to a mail piece, which is then scanned by the postal authority. The postal authority can obtain the stored postage indicium by reference to the indexing identifier. In this manner, the postal authority has access to the postage indicium without having to apply it to the mail piece. The indexing identifiers can optionally be used to index sender identification information for verifying that the sender of a mail piece is a trusted individual or entity.

Abstract: A method and system for detecting copy fraud using a unique character string, e.g., a tracking ID, is provided. This tracking ID can be associated with a postage indicium and digitally signed to provide for a self-validating unique postage indicium. The self-validating postage indicium can then be applied to a mail piece, e.g., a package, which are then processed through a postal authority, e.g., the USPS. Once validated by the postal authority, the tracking ID within the unique postage indicium can be compared to the tracking ID's in all other postage indicia to ensure that tracking ID is indeed unique and has not been duplicated. If the self-validating postage indicia on tracked mail pieces are only spot-checked, the tracking ID obtained from the validated postage indicium can be compared to a standard tracking ID found elsewhere on the mail pieces.

Abstract: A system for electronic distribution of postage includes at least one secure central computer for generating postal indicia in response to postage requests submitted by end user computers, and at least one postal authority computer system for processing the postal indicia on mail pieces. A key aspect of the system is that all secure processing required for generating postal indicia is performed at secure central computers, not at end user computers, thereby removing the need for specialized secure computational equipment at end user sites. A secure central computer includes a database of information concerning user accounts of users authorized to request postal indicia from the secure central computer. A request validation procedure authenticates received postage requests with respect to the user account information in the database.
