A method is described for tracking position of a mail piece within a facility. It includes steps of scanning a series of mail pieces to obtain identifying indicia therefrom, sorting the series of mail pieces according to a destination-based postal sorting strategy; and placing the sorted mail pieces into a container together with a marker comprising an RFID tag. In a computerized control system, identifiers for the RFID marker are identified with a sequence of mail pieces in the container. The RFID tag is scanned to associate a position of the container at the time of scanning with the mail in the container. The container is then transported, e.g. by loading a tray as the container onto a cart and then moving the cart. The method further includes video tracking the container from the position at the time of scanning to a later, different position at which a further postal operation takes place, such as loading of the trays onto a truck or feeding the mail from the trays onto the feeding ledge of a sorting machine hen a subsequent sorting step is needed.
