Claim:
A method for personalizing a chip card, comprising: storing key information in a memory of the chip card as part of partial personalization; and providing supplemental personalization by: transferring an instruction sequence definition to the chip card, transferring to the chip card an instruction sequence for creating a chip card application, the instruction sequence containing chip card instructions to be executed by the chip card, checking at least one of the chip card instructions using the key information to ascertain in a secure fashion whether the at least one of the chip card instructions satisfies the instruction sequence definition, and executing the at least one of the chip card instructions by the chip card if said checking is satisfied, and wherein the instruction sequence definition predefines states and state transitions of a state machine which changes from a particular state to a predefined subsequent state different from previously assumed states, the particular state having assigned thereto a predefined chip card instruction permitted for execution in the particular state.
