Abstract: The invention relates to a monitoring and/or directing system for parking areas which exhibit parking spaces. In order that the risk of theft is reduced and/if appropriate, incoming vehicles can be guided specifically to empty parking spaces, the monitoring and/or directing system is designed with at least one entrance and departure station provided for issue and retrieval of parking tickets fitted with an electronic identification element, with communicators which detect the parking tickets, there being arranged, at each parking space, at least one communicator which has a detection region directed towards the associated parking space, and with data lines via which the communicators and the entrance and departure stations are connected to a central computer.

Abstract: The invention concerns a parking card to operate a barrier for pay parking. The card is in the form of a round, flat piece with a front and back, and a machine-readable data medium for storing and identifying information on the parking facility and the user.

Abstract: The invention relates to a parking card which is intended for the charge-related actuation of a parking barrier and is in the form of a sheet-like plastic piece having a front side and rear side and having a machine-readable data carrier for storing car-park information and user information and, if appropriate, the entrance time and departure time. In order to provide a parking card which is easily constructed and can be handled with ease and permits the installation of an inexpensive parking service system, the invention provides that the plastic piece (1) is in the form of a round coin, on or in which there is mounted an identification and/or communication component (5) which operates in a contactless manner and comprises a chip and a data-transmission device which emits electromagnetic waves.

Abstract: A collection and issuing apparatus for round parking cards which exhibit an identification and/or communication element and are intended for the charge-related actuation of a parking barrier. The apparatus includes a supply container which exhibits, on the base side, a separation device for the parking cards, having an adjoining vertical shaft with at least one central guiding shaft and side shafts which branch off from the guiding shaft. The shafts exhibit a respective inclination and are intended for issuing and collecting parking cards in a rolling manner under the force of gravity. The apparatus also includes a measuring point which is located in the central shaft, intended for reading the parking cards, which are to be issued and/or collected again, and which is connected to a control device for actuating the parking barrier.

Abstract: The invention relates to a parking card to operate a barrier for pay parking. To create a parking card which is of simple and robust construction the parking card has a peripheral border region with a radially outwardly tapering thickness.
