Abstract
The postage system employs encryption techniques to verify that a user has printed postage. The postage at the time of printing is not accounted for by the meter. Accounting occurs at a time subsequent to the printing of postage. The user is provided with a postage validating device which provides an indication on the mailpiece of the validity of the imprint to identify the user and a user account number. Charges for the postage thus printed occur at a subsequent time. The imprint is read, preferably by scanning techniques, to determine validity, amount to be charged and an account number which is charged for the delivery.
