The postage machine works by using an imprint, often called the indicia or frank, which incorporates the greenback level of the postage applied, a dated postmark, in addition to a cancellation. The imprint or franking includes a barcode with the mail sender’s identification to stop the use of copyright postage. https://pingdirapp43.directoryup.com/top-level-category-1/wolf-packing-machine-company
