  • Patent number: 8826027
    Abstract: A method and a display preparation unit are proposed for the execution of a transaction during which transaction data are processed which have to be confirmed by a user. The display preparation unit has a converter unit which converts transaction data to be interpreted into pixel values and displays them on a monitor, an interface of its own for directly attaching an input unit via which a user confirms displayed transaction data, as well as a crypto unit for generating a signature for a record of confirmed transaction data. In a variant the confirmation can be effected by the crypto unit generating and displaying a random number which has to be inputted by the user via a conventionally attached input unit.

  • Patent number: 8816827
    Abstract: A method and a data carrier for contactless communication of a reading device with at least two communication-ready applications located on a portable data carrier. A first communication-readiness signal is generated for a first application and sent to the reading device, the signal having a first identification number that is assigned to the first application and indicates to the reading device the communication readiness of said first application, and a second communication-readiness signal is generated and sent for a second application, the second signal having a second identification number different from the first identification number, which is assigned to said second application and indicates to the reading device the communication readiness of the second application. The identification numbers simulate for the reading device the communication readiness of a data carrier in each case. The reading device thus has the impression of communicating with applications of two separate data carriers.

  • Patent number: 8819373
    Abstract: In a process for memory management in the execution of a program by a portable data carrier which has a first and a second memory region for the storage of objects generated in program execution, an object is initially created at least in part in the second memory region. If, in the course of further program execution, a persistent reference to the object is generated, the object is transferred to the first memory region. In a process for converting a source program into an executable program, a check is carried out at compile time as to whether a persistent reference to an object to be newly created is generated. Depending on the result of that check, program code is generated which creates the object either in the first or at least in part in the second memory region.

  • Patent number: 8806317
    Abstract: The invention relates to a method for encoding digital data, in particular of data processed in a microprocessor unit. In the method according to the invention for a respective data word (A, B, C) of a series of data words to be encoded subsequently a parity code (P(A), P(B), P(C)) is computed on the basis of the data of the respective data word (A, B, C). Further the respective data word (A, B, C) is altered with the aid of the data word (A, B, C) preceding it in the series, wherein the altered data word (Aa, Ba, Ca) and the parity code (P(A), P(B), P(C)) represent the encoded data word (Ac, Bc, Cc) and the encoded data word (Ac, Bc, Cc) can be decoded with the aid of the data word (A, B, C) preceding it in the series.

  • Patent number: 8794510
    Abstract: A method in which accounting units consisting of one or several bank notes are successively processed by a processing machine, wherein the bank notes are checked by a sensor device and a control device. One or several accounting units are inserted, the information items characterizing the accounting units are entered, the bank notes of each accounting unit are singled, checked, and in dependence on the check are assigned to output units of the processing machine The bank notes recognized upon the check are accounted for the respective accounting unit by the control device and transported into the assigned output unit. Bank notes not recognized upon the check are divided into two groups with a first group containing the unrecognized individual bank notes for which an identification feature characterizing the respective bank note can be ascertained by sensor device and control device, and a second group whose respective identification feature cannot be ascertained by the sensor device and control device.

  • Patent number: 8778834
    Abstract: A multi-layer card-shaped data carrier has a marking layer containing a hidden marking, and a thermochromic cover layer arranged over the marking layer at least in the area of the hidden marking. The thermochromic cover layer is opaque below its change temperature, hides the marking, and is translucent or transparent above its change temperature, enabling viewing of the marking. The thermochromic cover layer is pervious to radiation outside the visible spectral range and the marking layer absorbs radiation energy outside the visible spectral range, so that the hidden marking can be incorporated into the marking layer through the thermochromic cover layer by laser radiation of a wavelength outside the visible spectral range.

  • Patent number: 8766222
    Abstract: The invention relates to an apparatus and a method for checking the usage state of a document of value. The document of value is illuminated with illumination light and with the help of an image sensor there is detected the light intensity of the light reflected from the document of value in order to take an image of the document of value. Of the taken image there is chosen an image detail in which there is imaged an opaque, reflective section of the document of value. The chosen image detail is examined for signs of creases which are possibly present in the opaque, reflective section of the document of value. The results of the examination for creases are used to evaluate the usage state of the document of value.
