Abstract: An image-based verification system integrates with mail finishing equipment, such as an inserter, in much the same way as a postage meter. The verification system registers individual mail pieces as they are processed and dynamically builds a postage summary report to accompany mail when it is sent to the post office for delivery. The verification system is configured with the various weights and associated postage rates required, so variable weight mailings can be processed with only one device per inserter. Postage due is paid using a mailing permit, which is printed on the envelope and may include a date. The verification system provides greater protection for both the mailer and postal authority, as production data is not generated into a report until after mail post-processing as opposed to generating reports based on pre-processing data.
