Abstract
A postal apparatus, particularly a postage meter machine, has a chip card write/read unit for reloading fee schedule change data by chip card. In combination. with a first-time insertion of the chip card, an appertaining controller of the postage meter machine allows a first reloading and—as a result thereof—a writing of data into the chip card. The use data in the chip card are thereby modified in a predetermined way, so that, given a repeated data loading, the chip card supplies usable data only in the same postage meter machine. The use data are stored in a first memory area of the chip card and include the remaining use data and variable data, or a crypto code following the initial use. A protective code, formed after the. initial use for the authorization of the use data is stored in a second memory area of the chip card.
