  • Patent number: 8272573
    Abstract: A portable data carrier (1) comprising a contact pad (2) according to ISO 7816-2 as a physical interface for communication has a contactless interface device (7) for communication with an end device according to a contactless communication protocol via a preset activated contact assignment of the contact pad (2), and at least one contact interface device (4, 5, 6) for communication according to a contact-type communication protocol via a further activated contact assignment of the contact pad (2). In an initialization phase of the data carrier (1) a control device (3) activates a second contact interface device (4, 5, 6), besides an already activated contact interface device (4, 5, 6), only when the former does not use a contact assignment of the contact pad (2) that collides with the contact assignment of the contactless interface device (7).

  • Publication number: 20120237668
    Abstract: A method for producing solid particles having a silica coating, by: dispersing the solid particles to be coated in an aqueous medium to produce a solid particle dispersion, adjusting the pH of the solid particle dispersion by a buffer system to produce a buffered solid particle dispersion, and adding an alkaline silicate solution to the buffered solid particle dispersion to form the silica coating on the solid particles during a coating period. The amounts of buffer system and alkaline silicate solution are selected such that the pH of the buffered solid particle dispersion before the addition of the alkaline silicate solution is at least 7.0 and after completion of the addition of the alkaline silicate solution is at most 11.0.

  • Patent number: 8255699
    Abstract: A portable data carrier (1) comprises an executable training module (8) which provides in a memory (4, 5) of the data carrier (1) a reference model (10; M) for the biometric recognition of a user of the data carrier (1) by a recognition module (9), whereby a biometric comparison vector (16) which lies within the acceptance range (A) of the reference model (10; M) is accepted by the recognition module (9) as coming from the user. In so doing, the training module (8) defines the reference model (10; M) by model nodes (P, P0-P4) which are formed from biometric reference vectors (17; N) in each case coming from the user, whereby a new model node (P, P0-P4) is added to the reference model (10; M) when the associated reference vector (17; N) lies outside the acceptance range (A) of the reference model (10; M).

  • Patent number: 8251365
    Abstract: The invention relates to a device and a method for monitoring the separation of a sheet product, particularly of banknotes. The invention is based on a device and a method for monitoring the separation of a sheet product, particularly of banknotes, by means of a separator (1, 2, 3) having a drive (4, 7) and a controller (8) for monitoring and controlling the angular speed (w) of the separator, and is based on monitoring of the angular speed of the separator by the controller for changes and the determination of faulty separation, if the change of the angular speed is greater than a permitted deviation, or if the angular speed falls below a threshold value (S).

  • Patent number: 8245831
    Abstract: The invention relates to an apparatus and a method for checking bank notes wherein measuring values of the bank note to be checked are obtained and a classification of the bank note is carried out by evaluation of the measuring values in a plurality of checking steps, whereby the classification distinguishes in particular at least the classification categories, counterfeit, suspect and genuine bank notes, or acceptable or redispensable, and a linkage of a plurality of measuring values is formed at least in one checking step for deciding whether the checked bank note corresponds to a given classification category and this linkage term is compared with a corresponding tolerance range during evaluation.

  • Patent number: 8240663
    Abstract: A security container for storing documents of value in stack form is provided with a stacking pocket for receiving documents of value in a stacked form, a bottom element disposed in the stacking pocket on which rests a fed document of value or a stack of fed documents of value, and an inlet opening leading into the stacking pocket which is disposed such that documents of value fed to the security container fall onto the bottom element. In the transport direction there is disposed at least one closing element with at least one portion which is deflectable from a closing position, in which it prevents a motion of a document of value back into the inlet opening, into a passing position in which it guides the document of value and in which onto the portion there acts a restoring force driving towards the closing position.

  • Patent number: 8239683
    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 (20) has a converter unit (29) which converts transaction data to be interpreted into pixel values and displays them on a monitor (6), an interface of its own for directly attaching an input unit (7) via which a user confirms displayed transaction data, as well as a crypto unit (31) for generating a signature for a record of confirmed transaction data. In a variant the confirmation can be effected by the crypto unit (31) generating and displaying a random number which has to be inputted by the user via a conventionally attached input unit (14).

  • Publication number: 20120160632
    Abstract: The invention relates to a method and an apparatus for checking documents of value which have a security element with several magnetic areas, including at least one high-coercive magnetic area, at least one low-coercive magnetic area and at least one combined magnetic area which contains both the high-coercive and the low-coercive magnetic material. After the magnetization of all magnetic areas in a first direction, first magnetic signals of the security element are detected with a first magnetic detector. After a subsequent second magnetizing, which is effected antiparallel to the first magnetizing and magnetically reverses only the low-coercive magnetic material, second magnetic signals of the security element are detected. For identifying the magnetic areas, the second magnetic signals or a signal derived therefrom are compared with two thresholds.

  • Patent number: 8205249
    Abstract: A method for effecting a secure electronic transaction on a terminal using a portable data carrier is proposed. According to the method a user (30) first authenticates himself vis-à-vis the portable data carrier (20). The portable data carrier (20) at the same time produces quality information about how authentication was done. The authentication is confirmed to the terminal (14). Then the portable data carrier (20) performs a security-establishing operation within the transaction, for example the creation of a digital signature. It attaches the quality information to the result of the security-establishing operation.
