Abstract
Description
Die Erfindung betrifft einen tragbaren Datenträger, insbeson dere eine Chipkarte, mit einer Antenne und einem damit ver bundenen Halbleiterchip.The invention relates to a portable data carrier, in particular a chip card with an antenna and a ver bound semiconductor chip.
Solche sogenannten kontaktlosen Datenträger, insbesondere Chipkarten, werden schon seit einiger Zeit beispielsweise in Zutrittskontrollsystemen eingesetzt. Es gab jedoch auch schon Feldversuche, kontaktlose Datenträger in Form von Armbanduh ren bei Skiliften zu verwenden.Such so-called contactless data carriers, in particular Chip cards have been used for some time in Access control systems used. However, there have also been Field trials, contactless data carriers in the form of a wristwatch to be used with ski lifts.
Die US 4,701,601 beschreibt eine Chipkarte mit Kontaktfeldern für den kontaktbehafteten Betrieb in Chipkartenterminals und einer Sendespule zur Emulation eines Magnetstreifens für den Betrieb in herkömmlichen Magnetstreifenterminals. Um die ein gebaute Batterie nicht zu sehr zu belasten ist ein Sendeknopf vorgesehen, der das Senden von Daten über die Emulationsspule auf einen kleinen Zeitraum begrenzt.US 4,701,601 describes a chip card with contact fields for contact-based operation in chip card terminals and a transmitter coil for emulating a magnetic strip for the Operation in conventional magnetic stripe terminals. To the one The built-in battery is not too heavy to load provided the sending of data through the emulation coil limited to a short period of time.
Eine sich seit einiger Zeit im Gespräch befindende Einsatz möglichkeit von kartenförmigen, kontaktlosen Datenträgern ist die Verwendung als abbuchbares Zahlungsmittel im öffentlichen Nahverkehr. Diese Chipkarten sind hinsichtlich ihres Wertes wiederaufladbar, was bedeutet, daß ein einen Geldwert reprä sentierender Zählerstand auch erhöht werden kann. Sie weisen zu diesem Zweck zusätzlich zur Antenne Kontaktfelder auf, über die sie mittels eines Lese/Schreibterminals durch ohm sche Kontaktierung wieder aufgeladen werden können.An assignment that has been under discussion for some time possibility of card-shaped, contactless data carriers the use as a debitable means of payment in public Local transport. These smart cards are in terms of their value rechargeable, which means that one represents a monetary value sent meter reading can also be increased. You point for this purpose in addition to the antenna contact fields, via which they are read by ohm contact can be recharged.
Allen heute gebräuchlichen kontaktlosen und auch sowohl Kon taktelemente als auch eine Antenne aufweisenden Chipkarten oder allgemein Datenträgern ist gemeinsam, daß sie über die kontaktlose Schnittstelle mit Energie versorgt werden können und daß darüber auch die bidirektionale Datenübertragung stattfindet.All contactless and both con clock elements as well as an antenna chip cards or generally data carriers is common that they over the contactless interface can be supplied with energy and that also the bidirectional data transmission takes place.
Bei Datenträgern, deren Wert bei Benutzung verringert wird, also beispielsweise bei Verwendung als Zahlungsmittel im Nah verkehr, besteht die Gefahr, daß ein zufälliger Aufenthalt des Benutzers in der Nähe eines Abbuchungsautomaten zu einer Wertverringerung führt, ohne daß die entsprechende Dienstlei stung in Anspruch genommen wird. Auch könnte es zu Mehr fachabbuchungen führen, wenn der Aufenthalt auch bei ge wünschter Inanspruchnahme der Dienstleistung zu lange ist.For data carriers whose value is reduced when in use, for example when used as a means of payment in the near traffic, there is a risk of an accidental stay of the user near an ATM Loss of value leads without the corresponding service stung is used. It could also lead to more subject debits if the stay is also with ge desired use of the service is too long.
Das der Erfindung zugrunde liegende Problem ist es somit, ei nen tragbaren Datenträger anzugeben, der diesen Nachteil nicht aufweist.The problem underlying the invention is thus egg NEN portable disk, which has this disadvantage does not have.
Das Problem wird bei einem gattungsgemäßen Datenträger da durch gelöst, daß zwischen der Antenne und dem Halbleiterchip ein durch den Benutzer des Datenträgers betätigbares Schalt mittel angeordnet ist, so daß ein Empfang von Daten nur nach einer Betätigung des Schaltmittels möglich ist.The problem is there with a generic data carrier solved by that between the antenna and the semiconductor chip a switch which can be actuated by the user of the data carrier is arranged so that a receipt of data only after actuation of the switching means is possible.
Durch diese erfindungsgemäße Maßnahme hat es der Benutzer selbst in der Hand, den ]Datenträger zu aktivieren, so daß ein Datenempfang nur erfolgen kann, wenn dies der Benutzer wünscht.As a result of this measure according to the invention, the user has it even in hand to activate the] disk, so that a Data can only be received if this is the user wishes.
In Weiterbildung der Erfindung ist das Schaltmittel verrast bar ausgebildet, so daß eine ständige Verbindung zwischen der Antenne, die in vorteilhafter Weise als Spule ausgebildet sein kann, und dem Halbleiterchip, der zumindest einen Spei cher und Logikschaltungen enthält, eingestellt werden kann, falls der Benutzer dies wünscht, wobei er dann allerdings wieder dem Risiko ausgesetzt ist, daß Fehlabbuchungen vorkom men können. In a further development of the invention, the switching means is locked bar trained so that a constant connection between the Antenna, which is advantageously designed as a coil and the semiconductor chip, which has at least one memory and logic circuits, can be set, if the user so wishes, but then is again exposed to the risk that incorrect debits occur can.
Das durch den Benutzer betätigbare Schaltmittel, das als ein facher Druckschalter ausgeführt sein kann, kann als separates Bauteil in eine Aussparung der Karte, beispielsweise in einer Ecke der Karte eingesetzt sein oder auf einem den Halbleiter chip tragenden Trägerelement angeordnet sein.The switching means which can be operated by the user and which acts as a fold pressure switch can be carried out as a separate Component in a recess in the card, for example in a Corner of the card or on a semiconductor chip-bearing carrier element may be arranged.
Die Erfindung wird nachfolgend anhand eines Ausführungsbei spiels mit Hilfe von Figuren näher erläutert. Dabei zeigen:The invention is illustrated below with the aid of an embodiment game explained with the help of figures. Show:

Der Halbleiterchip 2 weist in bekannter Weise Speichereinheiten wie beispielsweise ein EEPROM sowie Logik schaltungen wie einen Mikroprozessor auf. Die Antennenspule 1 ist zur Energieübertragung zum und zur bidirektionalen Daten übertragung von und zum Halbleiterchip 2 mit diesem über ein Schaltmittel 3 verbunden. Das Schaltmittel 3 ist, wie durch einen Pfeil angedeutet ist, von außerhalb des Datenträgers durch den Benutzer betätigbar. Eine Energie- und Datenüber tragung von der Antennenspule 1 zum Halbleiterchip 2 kann al so nur stattfinden, wenn der Benutzer zuvor das Schaltmittel 3 betätigt hat.Referring to FIG. 1, the attached with a dashed line pointed disk, an antenna coil 1 and a semiconducting terchip 2. The semiconductor chip 2 has in a known manner memory units such as an EEPROM and logic circuits such as a microprocessor. The antenna coil 1 is to transfer energy to and for bidirectional data transmission from and to the semiconductor chip 2 connected thereto by a switching means 3 is connected. As indicated by an arrow, the switching means 3 can be actuated by the user from outside the data carrier. An energy and data transmission from the antenna coil 1 to the semiconductor chip 2 can thus take place only if the user has previously actuated the switching means 3 .
Fig. 2 zeigt einen Querschnitt durch einen erfindungsgemäßen Datenträger in Form einer Plastikkarte 6. Die Antennenspule 1 ist in einigen Windungen entlang der äußeren Abmessung der Plastikkarte geführt. Der Halbleiterchip 2 ist auf einem Trä gerelement 7 angeordnet und mittels diesem in bekannter Weise mit der Plastikkarte 6 beispielsweise durch Kleben verbunden. Zwei Enden 4a, 4b der Antennenspule 1 sind mit dem Trägerele ment 7 und über dieses mit dem Halbleiterchip 2 verbunden. Fig. 2 shows a cross section through an inventive data carrier in the form of a plastic card 6. The antenna coil 1 is guided in a few turns along the outer dimension of the plastic card. The semiconductor chip 2 is arranged on a carrier element 7 and connected by means of this in a known manner to the plastic card 6, for example by gluing. Two ends 4 a, 4 b of the antenna coil 1 are element 7 with the Trägerele and connected to this with the semiconductor chip 2 .
