Abstract: A mail processing method for franking mail items, which franking machine is connected to a first server that is itself connected to a second server in communication with a sorting machine, the franking method including scanning the destination addresses borne on the mail items as the mail items are inserted, storing the digital images of the addresses scanned in this way, in association with respective unique identification numbers, and periodically transferring the digital images as indexed in this way to a first server. The first or second server extracts determined data from the digital images, which data, associated with the unique identification numbers, is suitable for enabling the sorting machine to be controlled automatically on receiving the franked mail items.

Abstract: Methods and apparatus for authentication of postage indicia are disclosed. A secret key is read from store and modified in dependence upon postage data to be printed in a postage indicium. The modified key is then utilized to generate an authentication code dependent upon the postage data to be printed. Authentication of the indicium is effected by reading the authentication code and postage data from the printed indicium and repeating the process of generating an authentication code. The generated authentication code is compared with the authentication code read from the indicium. A control code based on a value in an accounting register may be included in the indicium. The value may be a value of postage dispensed in a determined expired period.

Abstract: Methods of verifying use of postage charges in respect of mail items are disclosed. An authentication code is derived from a secret identification of a sender and a part of the destination address of the item. The code is printed on the mail item together with a sender account reference. On receipt of the mail item, the postal authority is able to use the account reference to access the secret identification and thereby determine if the destination address derived corresponds to that printed on the mail to verify the payment for the postage charge. In a modification, each time a postage meter effects a transaction with a remote center, the remote center generates and transmits to the meter a transaction number. The meter utilises a unique key to generate an encrypted code based on an item count and the transaction number. The code and a meter identification are printed on the mail.

Abstract: A franking machine stores first data relating to a first impression second data relating to a second impression. Printing of both impressions or omission of the first impression and printing of only the second impression may be selected by a user. When both impressions are to be printed, the printing means is controlled to print the first impression in a first location on a mail item and to print the second impression in a second location on the mail item adjacent said first location. When omission of printing the first impression is selected the printing means is controlled to print the second impression in the first location.
