Abstract

A postage meter machine with a chip card write/read unit has a controller allows an initialization of a number of chip cards by the user in order, in conjunction with suitably initialized chip cards, to simplify the function input and the administration of cost center data to be handled. A chip card number is stored in the chip card. For deriving chip cards that set a limited function scope, a table with a specific hierarchic structure can be produced upon employment of the keyboard and display and with the assistance of the microprocessor and the appertaining non-volatile memories within the postage meter machine in that the pre-stored structure is correspondingly modified. At least one of the number of application functions is allocated to the chip card number in the table. A tree structure in the hierarchy thereby arises for second chip cards derived from the first chip card and for successor cards, particularly specific function application cards.

Dependent claims

A postage meter machine comprising:

a printer for printing an imprint on a print-receiving medium;
a control system connected to said printer for controlling a printing procedure resulting in printing of said imprint by said printer, said control system including a microprocessor, a memory connected to said microprocessor, and a user interface connected to said microprocessor;
a chip card write/read unit connected to said microprocessor;
a plurality of chip cards individually insertable into said chip card write/read unit, including a master card containing initialization data and a plurality of successor cards, each of said successor cards having a chip card number and, initially, containing no function data;
said master card, upon insertion thereof in said chip card write/read unit, allowing operation of said control system to download said initialization data into said memory;
said user interface allowing initialization of each of said successor chip cards as said successor chip cards are individually inserted in said chip card write/read unit after removal of said master card, including user modification of the chip card number of a successor chip card inserted in said chip card write/read unit and storage of function data dependent on said initialization data, for a limited function associated with said printing procedure, in the successor chip card inserted in said write/read unit, and thereby allocating said limited function to the successor chip card inserted in the chip card write/read unit;
after initialization of the successor chip card inserted in said chip card write/read unit, said memory storing the chip card number thereof and the limited function allocated thereto in a list, said list, after initialization of all of said plurality of successor chip cards resulting in a plurality of initialized chip cards, containing the respective chip card numbers of all of said plurality of initialized chip cards and the limited functions respectively allocated thereto;
and
after initialization of all of said plurality of successor chip cards, said microprocessor controlling said printing procedure dependent on one of said initialized chip cards inserted in said chip card write/read unit.

6 more elements

A method for operating a postage meter machine comprising the steps of:

providing a printer for printing an imprint on a print-receiving medium;
executing a printing procedure in a control system connected to said printer for controlling printing of said imprint by said printer, said control system including a microprocessor, a memory connected to the microprocessor, and a user interface connected to the microprocessor;
connecting a chip card write/read unit to said microprocessor;
providing a plurality of chip cards which are individually insertable into said chip card write/read unit, including a master card containing initialization data and a plurality of successor cards, each of said successor cards having a chip card number and, initially, containing no function data;
inserting said master card into said chip card write/read unit and downloading said initialization data therefrom into said memory to allow operation of said control system, and thereafter removing said master card from said chip card write/read unit;
after removal of said master card from said chip card write/read unit, successively inserting each of said successor chip cards individually into said chip card write/read unit, and initializing each of said successor chip cards using said user interface by modifying the chip card number of a chip card inserted in said chip card write/read unit and storing function data therein, dependent on said initialization data, and thereby allocating a limited function, associated with said printing procedure, to the chip card inserted in said chip card write/read unit;
after initializing a successor chip card inserted in said chip card write/read unit, storing the chip card number thereof in said memory and the limited function allocated thereto for producing, after initialization of all of said plurality of successor chip cards to produce a plurality of initialized chip cards, a list containing the respective chip card numbers of all of said plurality of initialized chip cards and the limited functions respectively allocated thereto;
and
after initialization of all of said successor chip cards, controlling said printing procedure via said microprocessor dependent on one of said initialized chip cards inserted in said chip card write/read unit.
