Abstract: A method of initializing and personalizing a chip card (100) and to a chip card (100) for this purpose. In accordance with the present invention, there are created in the data memory (102) of the chip card (100) data structures (200, 210, 300) which enable the personalizing data which is to be transmitted to the chip card (100) at the time of personalization to be unambiguously assigned to the various chip card applications and thus to the providers of these applications. As a result, the chip card applications are securely isolated from one another at the time of personalization.

Abstract: A help system having a first generator (110) for dynamically generating a user profile data set. This user profile data set stores, in particular with reference to a time base (140), help topic data sets (130) and/or the frequency and/or the type of a user's access to utilization functions of a software program. The help system further includes a second generator (150) for generating a user help profile data set. In this user help profile data set (150), at least selected help topic data sets (130), or program branches therefor, are stored as a function of the access data recorded in the user profile data set (110). Based on the user help profile data set (150), at least one user-specific help startup page (120) is dynamically generated, which allows for activating the help topic data sets (130) associated with the user help profile data set (150).

Abstract: A chip card system, whose chip cards (AK, LK) have in each case at least one internal processor (P) and a non-volatile memory (S) at least for an operating system of the processor (P). There are a multiplicity of user chip cards (AKn) whose processors (P) can in each case execute user command instructions only after an activation, and there is at least one license chip card (LK), in whose non-volatile memory (S) a limitable number of activatable user chip cards (AKn) can be managed. By means of at least one read-write station (AKg) for chip cards (LK), the activation of the internal processor (P) is effected in a user chip card (AKi) if in the memory (S) of the license chip card (LK) the number of activatable user chip cards (AKn) is not yet exhausted. Thereafter, the number of activatable user chip cards (AKn) is decremented in the memory (S) of the license chip card (LK).
