Abstract
An apparatus according to the invention for communication of an application (10) with a chip card (20) in which there is at least one application data storing means (30), also known as the dictionary, for recording of information concerning application specific data of the application (10), and at least one chip card dialog module (40), also known as the agent, for the generation of commands using the application data storing means (30) for an interface to the chip card (20), whereby the chip card dialog module (40) contains card specific data concerning the chip card (20). A request (100) for communication to the chip card (20) is made by the application (10) to the chip card dialog module (40) which is specified for the chip card (20). Upon the request (100), the chip card dialog module (40) generates at least one command (110), which is required for communication with the chip card (20). To achieve this, the chip card dialog module (40) accesses application specific information for itself which is stored in the application data storing means (30).
