A method, a memory data carrier () as well as a terminal () are proposed for accessing a portable memory data carrier () having a standardized memory element () and an additional module (). The method permits a data transmission selectively to the memory element () or to the additional module (). According to the method application data intended for the additional module () are generated, routing information for the application data, with information about the application data, is generated and added to the application data (), the resulting data stream is embedded in data blocks according to a transmission protocol adapted to the memory element () and transmitted, it is determined by the memory data carrier () whether a received data block contains routing information, and the data contained in the data block are routed to the additional module () if the data block contains routing information.

Method for access to a portable memory data support with auxiliary module and portable memory data support

A method is proposed for automatically installing an auxiliary unit () on a computer () that is not yet prepared for the auxiliary unit (). Upon connecting a new auxiliary unit () to the computer a registration routine () is carried out, within which operating routines () required for operating the auxiliary unit () are installed, after whose installation the auxiliary unit () is switchable from a basic mode to an auxiliary-unit specific operation mode. If the operating routines () are not yet present in the computer (), they are first transmitted to it by the auxiliary unit (). According to the invention it is determined whether a required operating routine () has to be transmitted by installing a background process () on the computer () which, upon the connection of an auxiliary unit (), checks whether identification information () re-transmitted to the computer () upon request is already stored on the computer ().
