Accessing portable data storage medium
with auxiliary module and portable data storage medium
Giesecke and Devrient GmbH, Munich, Germany, has been assigned a patent (9,104,895) developed by Martini, Ullrich, Munich, Germany, for a “method for accessing a portable data storage medium with auxiliary module and portable data storage medium.”

The abstract of the patent published by the U.S. Patent and Trademark Office states: ”The invention describes a method for accessing a portable storage data carrier, (10) having a controller, (12) for managing a standardized storage element, (14) and having an additional module, (16), wherein a data block is transferred to the storage data carrier, (10) in a first transmission protocol. The data block comprises routing information and application data, whereby the routing information contains an identifier which can be detected by the controller, (12). Furthermore, it is determined whether a data block received on the storage data carrier, (10) contains routing information. The data block is relayed to a storage area, (18) of the storage element, 14, said storage area being hidden to a terminal, (50), when the data block comprises routing information and the routing information comprises, besides the identifier contained therein, at least one further, predetermined parameter indicating the access to the hidden storage area, (18).“

The patent application was filed on May 5, 2010 (13/318,969).

Announcing memory configuration
Giesecke and Devrient GmbH, Munich, Germany, has been assigned a patent (9,104,322) developed by Bartsch, Armin, Landsberg am Lech, Germany, and Guter, Fabian, Feldkirchen, Germany, for a “method for announcing a memory configuration.”

The abstract of the patent published by the U.S. Patent and Trademark Office states: ”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.“

The patent application was filed on July 15, 2010 (13/383,969).
