Abstract: The invention creates a method for enabling a terminal to determine an activated memory configuration of a storage medium that can be operated in the terminal. For this purpose an interruption and subsequent restoration of the contact existing at an interface of the storage medium between the storage medium and the terminal is—at least partly—simulated, wherein upon the simulation of the restoration or interruption of the contact the terminal is caused to determine the activated memory configuration of the storage medium.

Abstract: A method, a memory data carrier (30) as well as a terminal (10) are proposed for accessing a portable memory data carrier (30) having a standardized memory element (34) and an additional module (40). The method permits a data transmission selectively to the memory element (34) or to the additional module (40). According to the method application data intended for the additional module (40) are generated, routing information for the application data, with information about the application data, is generated and added to the application data (108), the resulting data stream is embedded in data blocks according to a transmission protocol adapted to the memory element (34) and transmitted, it is determined by the memory data carrier (30) whether a received data block contains routing information, and the data contained in the data block are routed to the additional module (40) if the data block contains routing information.

Abstract: A storage medium having an encrypting device, including an electronic memory area, a read-in device, a read-out device, a key memory, in which a secret key is or can be stored, an encrypting device, and a decrypting device. The read-in device is designed to encrypt any data input at the interface for storage in the memory area using the key stored in the key memory and to store said encrypted data in the memory area. The read-out device has a direct read-out channel, by means of which stored encrypted data can be output to the interface in encrypted form by circumventing the decrypting device, and a decrypting read-out channel, by means of which stored encrypted data in the memory area can be decrypted by means of the decrypting device using the key stored in the key memory or a decryption key stored in the key memory and corresponding to the key and can be output to the interface in decrypted form.
