Abstract: For controlling access rights between a read/write device (1) and a transponder module (2) configured to exchange data via an electromagnetic field (3), the read/write device (1) obtains via the electromagnetic field (3) from the transponder module (2) a technology release code (T) which indicates a version of technology of the transponder module (2). Subsequently, the read/write device (1) sets access rights for the transponder module (2) using the technology release code (T). Setting access rights based on a technology release code (T) obtained from a transponder module (2) makes it possible to block transponder modules (2) selectively, depending on their inherent technology release, so that transponder modules (2) with a technology release that is without a security breach may remain in operation whereas transponder modules (2) with a technology release having a compromised security can be blocked from access.

Abstract: The invention is directed to an authentication system comprising a reader and a first and a second authentication media and a meta authentication media foreseen as a carrier between different authentication media and the reader.

Abstract: For detecting within a communication range of an antenna a contactless data storage device which is configured for inductive coupling with an electromagnetic field emitted by the antenna, a return signal is detected (S1) at the antenna during emission of an electromagnetic field pulse. During amplitude build-up of carrier oscillation at the beginning of the electromagnetic field pulse, an evaluation signal is generated (S2) based on the return signal, and the data storage device is detected (S3) based on the evaluation signal. By detecting the presence of the data storage device based on an evaluation signal generated during amplitude build-up, the detection of the data storage device can be initiated before carrier oscillation of the electromagnetic field pulse is stable. Consequently, the width of the electromagnetic field pulse can be shortened and, therefore, energy consumption for detecting the presence of the data storage device can be reduced.

Abstract: A mobile electronic device (1) comprises a data store (11), a transceiver (13) for wireless data exchange with another electronic device (2), and a processor (12) connected to the transceiver (13) and the data store (11). The processor (12) is programmed to implement a virtual card reader (121) which is configured to communicate with a smart card module (122, 20) that is arranged in the mobile electronic device (1). The virtual card reader (121) is implemented as a program running on processor (12). At least one smart card module (122) is a virtual card implemented as a program running on the processor (12). The virtual card reader (121) makes it possible to access smart card modules which are implemented locally in the mobile electronic device as a virtual card, thereby enabling access to a smart card module, without requiring an external reader device.

Abstract: A method of writing data into identification media of various types (IM-X, IM-Y) via assigned write/read stations WR in accordance with an embodiment of the present application includes a step wherein, a virtual, identification media-independent reference file system RFS is defined. All access keys RKi are replaced by a file system key FSK and all access rights ACi of subsections Bi are suspended and a file system FS, corresponding to the reference file system RFS, is initialized or written into the identification media: (FS(IM-X), FS(IM-Y)). In doing so, a file system starting point (FS-S(IM-X), FS-S(IM-Y)) is defined in the identification media (IM(FS) and in the assigned read/write stations WR(RFS) so that applications (App(RFS) corresponding to the virtual reference file system RFS can be written into the identification media and executed.

Abstract: In an apparatus for operating a read/writer, including an antenna and a read/write unit, for communication with an identification medium via a communication link, a read/writer supply and a read/writer have a breakable connection arranged between them. When there is a contactless (operative) interconnection between the external power supply and the read/writer, the connection between the read/writer supply and the read/writer is open and the read/writer can be operated with the identification medium.

Abstract: A reader device in accordance with an embodiment of the present disclosure includes an antenna connected electrically to a processing unit through an antenna connection element. The processing unit controls are configured to read data from a transponder module via an electromagnetic field. The reader device includes a user interface unit which is connected to the processing unit through the connection element and includes a data output part and/or a data input part. The data output part receives via the connection element reader data from the processing unit and outputs this data. The data input part receives via a data entry element user data and transmits this data via the connection element to the processing unit. Thus, user authentication data can be entered by the user and transmitted to the processing unit without the need for additional wiring between the user interface and the processing unit.
