Abstract:
1. A method for accessing a portable memory data carrier, having a controller for managing a standardized memory element and an additional module, comprising the following steps: generating application data intended for the additional module and containing an access thereto, generating routing information containing an identifier which can be recognized by the controller, combining the routing information and the application data to form a data stream, embedding the data stream in at least one data block according to a transmission protocol provided for accessing the memory element, transmitting the at least one data block to the memory data carrier in the transmission protocol adapted to the memory element, determining by the controller whether a data block received by the portable memory data carrier contains routing information, wherein the presence of routing information in the data block indicates that the data in the data block are intended for the additional module and the absence of routing information in the data block indicates that the data in the data block are intended for the memory element, and routing the application data contained in the data block to the additional module by the controller when the data block contains routing information, wherein application data to be transmitted are assigned a temporary working address in the memory data carrier and a response from the additional module to a command based on the application data is subsequently stored at the temporary working address.
