Claim:
Method of initializing and personalizing a chip card, wherein data for more than one chip card application is transmitted to the data memory of the chip card, comprising the steps of: during initialization: writing at least one application descriptor for each chip card application to the data memory of the chip card, said application descriptor designating the chip card application and comprising details of the memory address of a first personalization descriptor in a list of a plurality of personalization descriptors associated with said application; writing at least one personalization descriptor to the data memory of the chip card, with the personalization descriptor comprising details of the relative memory address of the next successive personalization descriptor in said list associated with said application; and during personalization: transmitting personalizing data for a chip card application to the chip card; writing of the personalizing data to the data memory of the chip card at the memory address for the first personalization descriptor indicated by the details in the application descriptor; transmitting the details of the relative memory address of the next successive personalization descriptor taken from the first personalization descriptor to the application descriptor so that the next successive personalization descriptor is then assigned to the application descriptor; and repeating the steps of personalization for all of the personalizing data which has to be transmitted for each chip card application, wherein the memory addresses for the personalization descriptors associated with each chip card application are distinct from the memory addresses of the personalization descriptors associated with other chip card applications.
