Abstract
In a postal charge accounting system, a control unit is connected to a card read-write unit which accepts one or more so-called "smart cards". Postage meter use information is written into and read from one of these cards. The postage expanded by the card user is stored in the card memory and can be displayed or printed out as desired. The system is applicable to delivery services other than postal mail which involve a franking operation.
