Abstract: A system for correcting the rating and payment of mail pieces scanned and weighed by the post. The foregoing is accomplished by: uniquely identifying mail pieces during the metering process; maintaining a record of the postage that has been applied to the mail pieces and the characteristics of the mail pieces; scanning the mail pieces to determine if the correct postage has been paid; comparing the scanned and weighed mail pieces to the maintained record; and correcting any underpayments or overpayments.
