A method for the tracking and identification of components of lithography systems, for example of projection exposure apparatuses for semiconductor lithography is provided. The components are each provided with at least one transponder. The transponder has a data memory, on which data relating to the respective component are stored. The transponder is configured to pick up wirelessly arriving signals of a reader and to respond with data from the data memory. The data are stored on the data memory during the production of the component and/or during the production of the lithography system and/or after the start-up of the lithography system.
