Abstract: A non-contact-type access authorization reading device on an access control apparatus (1) reads an access authorization stored in a data carrier (9) received by an object (ski 7) which the user carries near the ground. The reading device has an antenna (11) disposed in the ground area and is connected to an evaluation unit which releases the access (2) upon reading of a valid access authorization. To provide the data carrier (9) with an access authorization, a copy-over data carrier (12) is acquired which stores a coding authorization for an access authorization. A copy-over reading device reads the coding authorization on the copy-over data carrier (12), and a coding device contactlessly codes the access authorization on the access authorization data carrier (9), the coding authorization being deleted after coding.

Abstract: A system with at least one access control device (1) exhibiting an access authorization reader (4) for data carrier (8) containing access authorization and identification data, a database (9) and a camera (7). Once a valid access authorization is read, the identification data from the data carrier in question (8) and a digitized image of the user taken by the camera (7) are stored in the database. The stored image of the user of the particular data carrier can be transferred from the database (9) to terminals (11 to 13), in order to compare it with a image of the user previously taken and stored in the database (9). If the images of the user do not match, further access is denied for that particular data carrier (8).

Abstract: At an access control device (1) with a reading device (4) for data carriers (8), on which access authorization and identification details are stored, a camera (7) is envisaged that takes digitized photographs of the users of the access control device (1), which are then stored in a database (9) together with the identification details read from the data carrier (8) by the reading device (4). An official (15) operates a terminal with a screen (12) that communicates with the database (9), through which the identification details on the data carrier (8) are verified, and to which the stored photograph of the user of the data carrier (8), taken by the camera (7) during access to the access control device (1) by the user, is transmissible for visual comparison with the user being checked (16).

This is achieved according to the invention by providing a thermally conductive separating wall (9) between the pump chamber (2) and the rotor chamber (8).

Abstract: A data carrier for a non-contact data communication with a control station controlling a passage to an area or space comprises a carrier base structure, a data sending-receiving unit, a non-volatile, electrically erasable and programmable memory, a liquid crystal display for displaying data, and a solar cell unit for providing power. When the data carrier is approached to the control station, data are received from and transmitted to the control station which checks and/or changes the data content of the memory. A means for making visible the stored data on the liquid crystal display, e.g. a microprocessor, and the liquid crystal display are powered by the solar cell unit. The data carrier can be designed as a disk and handled like a coin. A housing of the data carrier can be provided with a cord wound on a spring acted spool.

Abstract: The invention is a data carrier comprising a carrier base structure, a non-volatile, electrically erasable and programmable memory designed to store the data, a data sending-receiving unit for receiving data from a control unit and transmitting data to a coding and/or reading station, a liquid crystal display, means for making visible on the liquid crystal display the data contained in the memory, and a power supply means having a power source arranged in the data carrier.

Abstract: A motor driven turnstile for providing cyclic access to a passage (16) to which a monitoring system or the like is allocated. The turnstile is controlled in such a way that, after a satisfactory monitoring result, each blocking arm (4) is first taken from the blocking position to a stopping position located at a small angle (alpha) from the blocking position, in which, after external pressure applied by the user, the arm is once again driven by the drive motor (6) and turned further until the next arm is in the blocking position.

Abstract: To permit visual monitoring of the owner of a data carrier in the form of a wrist-watch, a photo of the owner is incorporated in the clasp attached to the strap of the data carrier.

Abstract: For automated communication in a limited acquisition space, for example in order to identify or check an access authorization, use is made of active data supports which comprise a transmitter (15), a receiver (16), a read-write memory, an electric clock, a computer, a display and a power source (7). The checking station is also provided with a transmitter-receiver to check and possibly modify the data. Each transmitter-receiver has a limited communication space, of which the maximum extent is less than the minimum extent of the acquisition space. In this way it is not necessary to plug in the data support, of which a precise point must, however, be deliberately brought close to the checking station. In this way a definite coordination between the checking station and a further data support is prevented.

Abstract: An autonomous device that can be carried in one hand is used for checking and at least partially obliterating machine-readable data carriers. The device contains all components necessary to read and modify data and is provided with a card conveyor and a line-by-line printing device for processing data carriers having the form of card tokens.

Abstract: In order to control or identify an authorization of access, use is made of a control station which has two different read-write systems. The first unit is designed in particular for remote control of active date carriers comprising a microcomputer. The second read-write system is designed for the control of passive data carriers, on which the data are stored in a magnetic or optical form. Preferably both read-write systems are provided with parallel outputs, to which a switching system is connected, which passes to the peripheral systems the output signals produced by means of the desired data carrier.
