A mail processing machine comprises a first holding location that is adapted to hold a stack of first pages. A card is coupled to each of the first pages, and each first page includes an identifier. A second holding location is adapted to hold a stack of second pages that each have an identifier. A first advancing mechanism is adapted to separately advance each first page from the stack, and a second advancing mechanism is adapted to separately advance each second page from the stack. First and second scanning devices read the identifiers on the first and second pages upon their advancement. A controller is configured to control the first and second advancing mechanism to permit the first and second pages to be scanned by the first and second scanners and to match the first pages with the second pages if the identifier on one of the advanced first pages corresponds with the identifier on one of the advanced second pages.
