Abstract

A translator (300) for generating a tool (315) for a modifying data on a chip card (10) or for a communicating with the chip card (10) is proposed, the translator (300) receiving as input data a description (310) in a card definition language provided for that purpose, said description (310) comprising information about objects on the chip card (10) which are described with the use of constructional instructions. The translator (300) comprises a means for generating an internal list of attributes (320) from the information about the objects in the description (310), there existing for each object at least one entry (330) in the internal list of attributes (320). The translator (300) furthermore comprises at least one structure information means (335) describing how the data stored in the at least one entry (330) in the internal list of attributes (320) is transformed into the format determined for the chip card (10), which information from the at least one entry (330) is used and in which format it is stored in the special structure.
