Description

Kartenlesegerät für zwei wechselbare Chipkarten Card reader for two exchangeable chip cards
Technisches GebietTechnical field
Die Erfindung betrifft eine Vorrichtung zum Zugreifen auf wenigstens zwei wechselbare Chipkarten, mit einer Leseein- richtung je wechselbarer Chipkarte, wobei jede Leseeinrichtung eine Kontaktstation zum Kontaktieren des Chips der jeweiligen Chipkarte und eine Transportvorrichtung enthält, die die wechselbare Chipkarte in eine Kontaktstellung bezüglich der Kontaktstation bringt.The invention relates to a device for accessing at least two exchangeable chip cards, with a reading device for each exchangeable chip card, each reading device containing a contact station for contacting the chip of the respective chip card and a transport device which brings the changeable chip card into a contact position with respect to the contact station .
Mit der fortschreitenden Verbreitung von Chipkarten wird es in Zukunft vermehrt Anwendungen geben, die den gleichzeitigen Zugriff auf Daten von zwei wechselbaren Chipkarten erfordern. Beispielsweise lassen sich Chipkarten als Schlüssel verwenden. Der Zutritt zu einem Sicherheitsbereich ist dabei nur möglich, wenn zwei Personen ihre Chipkarten in ein als VTürschloßV verwendetes Kartenlesegerät einführen. Bisher bekannte Kartenlesegeräte, die im Zahlungsverkehr eingesetzt werden, sind für solche Anwendungen, die den Zugriff auf zwei wechselbare Chipkarten erfordern, nicht ge- eignet, weil bei ihnen eine Chipkarte, die sogenannte Händlerkarte, fest in dem Kartenlesegerät eingebaut ist.As chip cards become more widespread, there will be more applications in the future that require simultaneous access to data from two exchangeable chip cards. For example, chip cards can be used as keys. Access to a security area is only possible if two people insert their chip cards into a card reader used as a door lock. Previously known card readers, which are used in payment transactions, are not suitable for those applications which require access to two exchangeable chip cards, because a chip card, the so-called merchant card, is permanently installed in the card reader.
Für die oben genannten Anwendungen werden im Stand der Technik daher zwei getrennte Kartenlesegeräte eingesetzt. Ein Problem bei dieser Lösung ist, daß etwa im Eingangsbe- reich einer Tür für zwei getrennte Kartenlesegeräte in der Regel nicht genügend Platz zur Verfügung steht. Stand der TechnikFor the above-mentioned applications, two separate card readers are therefore used in the prior art. One problem with this solution is that there is generally not enough space available in the entrance area of a door for two separate card readers. State of the art
Aufgabe der Erfindung ist es daher, eine Vorrichtung eingangs genannter Art zur Verfügung zu stellen, die im Bereich eines Bedienfeldes wenig Platz beansprucht und sich gut gegen Manipulationen schützen läßt.The object of the invention is therefore to provide a device of the type mentioned at the beginning which takes up little space in the area of a control panel and can be well protected against manipulation.
Diese Aufgabe wird durch eine Vorrichtung mit den im kennzeichnenden Teil des Anspruchs 1 angegebenen Merkmalen gelöst. Vorteilhafte Weiterbildungen ergeben sich aus den abhängigen Ansprüchen.This object is achieved by a device with the features specified in the characterizing part of claim 1. Advantageous further developments result from the dependent claims.
Der Erfinder hat erkannt, daß sich bei einer Vorrichtung eingangs genannter Art der Platzbedarf im Bereich des Bedienfeldes nur vermindern läßt, wenn mehrere Leseeinrichtungen über dieselbe Einführöffnung eines Gehäuses der Vorrichtung erreichbar sind.The inventor has recognized that the space required in the area of the control panel can only be reduced in a device of the type mentioned above if several reading devices can be reached via the same insertion opening of a housing of the device.
Die gemeinsame Steuerung weist die erste Transportvorrichtung, die sich in unmittelbarer Nähe der Einführöffnung befindet, an, eine erste in die Vorrichtung eingeführte Chipkarte an die weitere Transportvorrichtung weiterzugeben. Aufgabe der gemeinsamen Steuerung ist es, die Transportvor- richtungen der Leseeinrichtungen so aufeinander abzustimmen, daß jede eingeführte Chipkarte zu der für sie bestimmten Kontaktstation transportiert wird. Die eingeführte Chipkarte wird nur dann an die Transportvorrichtung einer nachfolgenden Leseeinrichtung weitergegeben, wenn sich in der nachfolgenden Leseeinrichtung noch keine Chipkarte befindet. Entsprechend wird nach Abschluß des Bearbeitungsvorganges zunächst diejenige Chipkarte zurückgegeben, die sich in der unmittelbar an die Einführöffnung anschließen- den Leseeinrichtung befindet . Danach wird die Chipkarte der nachfolgenden Leseeinrichtung ausgegeben usw.The common controller instructs the first transport device, which is located in the immediate vicinity of the insertion opening, to forward a first chip card inserted into the device to the further transport device. The task of the joint control is to match the transport devices of the reading devices to one another in such a way that each inserted chip card is transported to the contact station intended for it. The inserted chip card is only passed on to the transport device of a subsequent reading device if there is no chip card in the following reading device. Accordingly, after completion of the processing operation, the chip card that is connected to the insertion opening immediately is returned. the reader is located. The chip card of the subsequent reading device is then issued, etc.
Die erfindungsgemäße Vorrichtung hat nicht nur einen geringen Platzbedarf im Bereich des Bedienfeldes, sondern läßt sich auch gut gegen Manipulationen schützen, weil es nur eine Einführöffnung gibt, die zu überwachen ist. Im Vergleich mit Kartenlesegeräten mit fest eingebauter Chipkarte vermeidet die Erfindung, daß eine Chipkarte permanent im Kartenlesegerät verbleibt und damit für unerwünschte Zu- griffe leicht zugänglich ist.The device according to the invention not only takes up little space in the area of the control panel, but can also be well protected against manipulation, because there is only one insertion opening that is to be monitored. In comparison to card readers with a permanently installed chip card, the invention prevents a chip card from remaining permanently in the card reader and thus being easily accessible for undesired access.
Die Erfindung läßt sich auf einfache Weise dadurch realisieren, daß man zwei, hintereinander angeordnete getrennte Kartenlesegeräte aneinander befestigt. Im Gehäuse des ersten Kartenlesegerätes befindet sich als Ausgang ein Durch- bruch, so daß die Transportvorrichtungen des ersten und des zweiten Kartenlesegerätes eine durchgehende Transportbahn bilden. Durch die erste Einführöffnung des ersten Kartenlesegerätes werden die Chipkarten der Vorrichtung zugeführt . Eine erste eingeführte Chipkarte wird von der Transportvor- richtung des ersten Kartenlesegerätes durch den Durchbruch an die Transportvorrichtung des zweiten Kartenlesegerätes weitergereicht. Die erste Einführöffnung hat einen Schließer, der diese nur zum Einführen und bei der Rückgabe der Chipkarten freigibt. Damit wird das Eindringen von Schmutz und Feuchtigkeit in die Vorrichtung vermieden. Zusätzlich erschwert der Schließer das Manipulieren und Zerstören oder Beschädigen der Vorrichtung, insbesondere deren KontaktStationen.The invention can be implemented in a simple manner by fastening two card readers arranged one behind the other to one another. There is an opening in the housing of the first card reader as an exit, so that the transport devices of the first and second card readers form a continuous transport path. The chip cards of the device are fed through the first insertion opening of the first card reader. A first inserted chip card is passed on by the transport device of the first card reader through the opening to the transport device of the second card reader. The first insertion opening has a closer, which only releases it for insertion and when the chip cards are returned. This prevents dirt and moisture from entering the device. In addition, the closer makes it difficult to manipulate and destroy or damage the device, in particular its contact stations.
Ein Schließer für die zweite Einführöffnung entfällt. Diese Maßnahme vereinfacht die Ausgestaltung des zweiten Karten- lesegerätes, verkürzt die Fertigungszeiten und senkt die Materialkosten der Vorrichtung.There is no closer for the second insertion opening. This measure simplifies the design of the second card reader, shortens production times and lowers the material costs of the device.
Insbesondere im bargeldlosen Zahlungsverkehr dürfen nur zertifizierte Kartenlesegeräte eingesetzt werden, die z.B. vorgegebene Verschlüsselungsverfahren beim Speichern der Daten im Chip verwenden. Ein besonderer Vorteil des vorstehend beschriebenen Ausführungsbeispieles ist daher, daß ihre erneute Zertifizierung nicht notwendig ist, da zwei bereits zertifizierte Kartenlesegeräte benutzt werden. Die Zertifizierung eines Kartenlesegerätes ist für den Hersteller eines Kartenlesegerätes mit einem hohen Kosten- und Zeitaufwand verbunden, der bei diesem Ausführungsbeispiel vermieden wird.Especially in cashless payments, only certified card readers may be used, e.g. Use the specified encryption method when storing the data in the chip. A particular advantage of the exemplary embodiment described above is therefore that re-certification is not necessary since two card readers that have already been certified are used. The certification of a card reader is associated with a high cost and time expenditure for the manufacturer of a card reader, which is avoided in this embodiment.
Bei der erfindungsgemäßen Lösung können die Kontaktstatio- nen und die Transportvorrichtungen des ersten und des zweiten Kartenlesegerätes mit einem Rechner verbunden sein, der als gemeinsame Steuerung benutzt wird.In the solution according to the invention, the contact stations and the transport devices of the first and the second card reader can be connected to a computer which is used as a common control.
Der Rechner arbeitet ein Programm ab, das die Transportvor- richtungen und die Kontaktstationen des ersten und des zweiten Kartenlesegerätes entsprechend einer Anwendung steuert .The computer runs a program that controls the transport devices and the contact stations of the first and second card reading devices according to an application.
Vorzugsweise werden die Chipkarten erst kontaktiert, wenn beide bezüglich der jeweiligen Kontaktstation positioniert worden sind. Es ist jedoch durchaus denkbar, daß die Kon- taktstation des zweiten Kartenlesegerätes die erste Chipkarte bereits kontaktiert, während die zweite Chipkarte noch positioniert wird.The chip cards are preferably only contacted when both have been positioned with respect to the respective contact station. However, it is entirely conceivable that the contact station of the second card reader already contacts the first chip card while the second chip card is still being positioned.
Bei dieser Ausführungsform greift der Rechner über die beiden Kontaktstationen auf die erste und die zweite Chipkarte zu. Alternativ ist denkbar, daß die beiden Kontaktstationen Daten direkt miteinander austauschen. Eine weitere Alternative sieht daher vor, Chipkartencontroller des ersten und des zweiten Kartenlesegerätes elektrisch miteinander zu verbinden, so daß ein Datenaustausch möglich ist. Die Chipkartencontroller haben die Aufgabe, die Leseeinrichtung und die Transportvorrichtung des jeweiligen Kartenlesegerätes zu steuern.In this embodiment, the computer accesses the first and the second chip card via the two contact stations to. Alternatively, it is conceivable that the two contact stations exchange data directly with one another. A further alternative therefore provides for electrically connecting chip card controllers of the first and second card reading devices to one another, so that data exchange is possible. The chip card controllers have the task of controlling the reading device and the transport device of the respective card reading device.
Das Gehäuse der Vorrichtung wird vorzugsweise aus den Ge- hausen der Kartenlesegeräte gebildet . Die Gehäuse der Kartenlesegeräte sind beispielsweise miteinander verschraubt. Ferner ist es möglich, die Gehäuse so auszubilden, daß sie ineinander gesteckt und gegebenenfalls verschraubt werden können. Dies ergibt eine besonders verwindungssteife Ver- bindung .The housing of the device is preferably formed from the housings of the card readers. The housings of the card readers are screwed together, for example. Furthermore, it is possible to design the housing so that it can be inserted into one another and, if necessary, screwed together. This results in a particularly torsionally rigid connection.
Bei einer vorteilhaften Weiterbildung der erfindungsgemäßen Vorrichtung hat jede Leseeinrichtung eine Positioniervorrichtung zum Festlegen der Kontaktstellung der jeweiligen Chipkarte bezüglich der jeweiligen KontaktStation. Die Po- sitioniervorrichtungen können Lichtschranken und/oder bewegliche Anschlagelemente sein. Die beweglichen Anschlagelemente sind zwischen einer in die Transportbahn eingreifenden Sperrstellung und einer die Transportbahn freigebenden Freigabestellung bewegbar. Durch die Verwen- dung von Positioniervorrichtungen wird vermieden, daß die Lage der Chipkarte bezüglich der Kontaktstation indirekt, d.h. z.B. über die Transportgeschwindigkeit, ermittelt werden muß .In an advantageous development of the device according to the invention, each reading device has a positioning device for determining the contact position of the respective chip card with respect to the respective contact station. The positioning devices can be light barriers and / or movable stop elements. The movable stop elements can be moved between a blocking position engaging in the transport path and a release position releasing the transport path. The use of positioning devices prevents the position of the chip card with respect to the contact station being indirect, i.e. e.g. about the transport speed, must be determined.
Bei einer Weiterbildung der Vorrichtung werden auch die Po- sitioniervorrichtungen von der gemeinsamen Steuerung ge- steuert. Wie bereits erläutert, werden die eingeführten Chipkarten nacheinander in der jeweiligen Leseeinrichtung bezüglich der Kontaktstation positioniert. Der gemeinsamen Steuerung ist also bekannt, zu welcher Leseeinrichtung eine nächste, eingeführte Chipkarte zu transportieren ist. Sind die Positioniervorrichtungen beispielsweise bewegliche Anschlagelemente veranlaßt die gemeinsame Steuerung, daß sich die Anschlagelemente, derjenigen Leseeinrichtungen, die sich zwischen der Einführδffnung und einer Zielleseeinrich- tung befinden, in der Freigabesteilung befinden, bis die Chipkarte die Zielleseeinrichtung erreicht hat.In a further development of the device, the positioning devices are also controlled by the common control. controls. As already explained, the inserted chip cards are positioned one after the other in the respective reading device with respect to the contact station. The common control unit therefore knows to which reading device a next, inserted chip card is to be transported. If the positioning devices are, for example, movable stop elements, the common control causes the stop elements, those reading devices which are located between the insertion opening and a target reading device, to be in the release division until the chip card has reached the target reading device.
Zum Lesen der Daten von Magnetstreifen der eingeführten Chipkarten kann entlang der Transportbahn mindestens ein Magnetlesekopf angeordnet sein, an dem die Chipkarten vor- beigeführt werden. Auf den Magnetlesestreifen können Identifizierungsmerkmale von Benutzern, z.B. eine PIN (Personal Identification Number) , gespeichert sein. Darüber hinaus ist anhand des Magnetlesestreifens zu erkennen, ob die Chipkarten richtig herum in die Vorrichtung eingeführt wor- den sind.To read the data from magnetic strips of the inserted chip cards, at least one magnetic reading head can be arranged along the transport path, on which the chip cards are guided. Identification features of users, e.g. a PIN (Personal Identification Number). In addition, it can be seen from the magnetic reading strip whether the chip cards have been inserted into the device in the correct direction.
Ein Magnetlesekopf ist zweckmäßigerweise zwischen der Ein- führδffnung und der Kontaktstation einer benachbarten Leseeinrichtung angeordnet. Diese Stelle der Transportbahn passieren alle eingeführten Chipkarten. Damit ist es möglich, daß der Magnetlesekopf die Magnetlesestreifen aller eingeführten Chipkarten abtastet . Im Vergleich zu der eingangs beschriebenen Lösung im Stand der Technik, die zwei vollständig ausgerüstete Kartenlesegeräte benötigt, werden durch diese Weiterbildung die Fertigungskosten gesenkt, da nur ein Magnetlesekopf benötigt wird. Vom Magnetlesekopf eingelesene Daten der eingeführten Chipkarten werden beispielsweise an die gemeinsame Steuerung übermittelt. Die gemeinsame Steuerung hat einen Speicher, in dem diese Daten abgelegt werden.A magnetic reading head is expediently arranged between the insertion opening and the contact station of an adjacent reading device. All inserted chip cards pass this point on the transport track. This makes it possible for the magnetic reading head to scan the magnetic reading strips of all the inserted chip cards. In comparison to the prior art solution described at the outset, which requires two fully equipped card readers, this development reduces the manufacturing costs since only one magnetic reading head is required. From the magnetic read head Read data from the inserted chip cards are transmitted to the common control, for example. The common control has a memory in which this data is stored.
Ferner ist es möglich, daß sich in Einführrichtung hinter den Leseeinrichtungen eine Auffangvorrichtung für Chipkarten befindet. In einer solchen Auffangvorrichtung werden z.B. ungültige Chipkarten abgelegt. Wird etwa während des Bearbeitens der Chipkarten festgestellt, daß eine Chipkarte manipuliert worden ist, veranlaßt die gemeinsame Steuerung die Transportvorrichtungen derjenigen Leseeinrichtungen, die sich zwischen der Leseeinrichtung mit der manipulierten Chipkarte und der Auffangvorrichtung befinden, die ungültige Chipkarte in der Auffangvorrichtung abzulegen.Furthermore, it is possible that there is a collecting device for chip cards in the insertion direction behind the reading devices. In such a collecting device e.g. invalid chip cards filed. If, for example, during the processing of the chip cards it is found that a chip card has been manipulated, the common control causes the transport devices of those reading devices which are located between the reading device with the manipulated chip card and the collecting device to put the invalid chip card in the collecting device.

Transportrollenpaare 28, 30, 32 bilden eine erste Transportvorrichtung der ersten Leseeinrichtung 16. Transpor- trollenpaare 34, 36, 38 bilden eine zweite Transportvor- richtung, die zur zweiten Leseeinrichtung 18 gehört. Die Transportrollenpaare 28 bis 38 sind in einer Flucht mit der verschließbaren Öffnung 22 angeordnet und bilden eine durchgehende Transportbahn. Die Transportrollenpaare 28 bis 38 sind über Leitungen 40, 42 und 44 mit einer gemeinsamen Steuerung 46 verbunden.Transport roller pairs 28, 30, 32 form a first transport device of the first reading device 16. Transport roller pairs 34, 36, 38 form a second transport device which belongs to the second reading device 18. The pairs of transport rollers 28 to 38 are arranged in alignment with the closable opening 22 and form a continuous transport path. The pairs of transport rollers 28 to 38 are connected via lines 40, 42 and 44 to a common controller 46.
Die erste Transportvorrichtung führt eine erste eingeführte Chipkarte 14 durch die erste Leseeinrichtung 16 und gibt sie an die zweite Transportvorrichtung weiter. Die zweite Transportvorrichtung bringt die erste Chipkarte 14 in eine Kontaktsteilung bezüglich einer ersten Kontaktstation 48, die zur zweiten Leseeinrichtung 18 gehört. Eine zweite ein- geführte Chipkarte 12 wird von der ersten Transportvorrichtung in eine Kontaktposition bezüglich einer zweiten Kontaktstation 50 gebracht. Ein erstes bewegliches Anschlagelement 52 legt die Kontaktposition bezüglich der zweiten Kontaktstation 50 fest, so daß diese einen Chip 54 der zweiten Chipkarte 12 kontaktieren kann. Das erste bewegliche Anschlagelement 52 ist in Richtung des Pfeiles 26 zwischen einer in die Transportbahn eingreifenden Sperrstellung und einer die Transportbahn freigebenden Freigabestel- lung bewegbar. Ein zweites bewegliches Anschlagelement 56 gehört zur zweiten Leseeinrichtung 18. Das zweite bewegliche Anschlagelement 56 legt die Kontaktposition bezüglich der ersten Kontaktstation 48 fest, um einen Chip 58 der ersten Chipkarte 14 zu kontaktieren.The first transport device guides a first inserted chip card 14 through the first reading device 16 and forwards it to the second transport device. The second transport device brings the first chip card 14 into a contact division with respect to a first contact station 48, which belongs to the second reading device 18. A second one guided chip card 12 is brought into a contact position with respect to a second contact station 50 by the first transport device. A first movable stop element 52 defines the contact position with respect to the second contact station 50 so that it can contact a chip 54 of the second chip card 12. The first movable stop element 52 can be moved in the direction of the arrow 26 between a blocking position engaging in the transport path and a release position releasing the transport path. A second movable stop element 56 belongs to the second reading device 18. The second movable stop element 56 defines the contact position with respect to the first contact station 48 in order to contact a chip 58 of the first chip card 14.
In der ersten Leseeinrichtung 16 befindet sich zwischen einem ersten Transportrollenpaar 28 und einem zweiten Transportrollenpaar 30 ein Magnetlesekopf 60. Mit Hilfe des Magnetlesekopfes 60 werden Daten gelesen, die auf Magnetstreifen der wechselbaren Chipkarten 12, 14 gespeichert sind.A magnetic reading head 60 is located in the first reading device 16 between a first pair of transport rollers 28 and a second pair of transport rollers 30. The magnetic read head 60 is used to read data which are stored on magnetic strips of the exchangeable chip cards 12, 14.
Die erste und die zweite Kontaktstation 48 bzw. 50 sowie der Magnetlesekopf 60 und die gemeinsame Steuerung 46 sind mit einem Rechner 62 verbunden. Der Rechner 62 arbeitet ein Programm ab, das Daten verarbeitet, die die erste und die zweite Kontaktstation 48 bzw. 50 von den Chips 58 bzw. 54 gelesen haben. Über diesen Rechner 62 erfolgt der Datenaustausch zwischen den Kontaktstationen 48,50.The first and the second contact stations 48 and 50 as well as the magnetic reading head 60 and the common control 46 are connected to a computer 62. The computer 62 executes a program that processes data that the first and the second contact stations 48 and 50 have read from the chips 58 and 54, respectively. The data exchange between the contact stations 48, 50 takes place via this computer 62.
Figur 2 zeigt eine Frontansicht des Kartenlesegerätes 10.FIG. 2 shows a front view of the card reading device 10.
Eine erste Leuchtdiode 64 leuchtet und fordert einen Benut- zer auf, die erste Chipkarte 14 in die verschließbare Ein- führöffnung 22 zu schieben. Eine zweite Leuchtdiode 66 leuchtet auf, sobald die erste Chipkarte 14 die Kontaktposition bezüglich der ersten Kontaktstation 48 erreicht hat. Gleichzeitig wird durch das Aufleuchten der zweiten Leucht- diode 66 der Benutzer aufgefordert, die zweite Chipkarte 12 durch die verschließbare Öffnung 22 in das Kartenlesegerät 10 einzuführen.A first light-emitting diode 64 lights up and prompts a user to insert the first chip card 14 into the lockable Slide guide opening 22. A second light-emitting diode 66 lights up as soon as the first chip card 14 has reached the contact position with respect to the first contact station 48. At the same time, when the second light-emitting diode 66 lights up, the user is prompted to insert the second chip card 12 into the card reader 10 through the closable opening 22.
Die Abmessungen einer Frontplatte 68 des Kartenlesegerätes 10 sind gleich den Abmessungen einer Frontplatte eines Kar- tenlesegerates, das nur eine Leseeinrichtung für eine wechselbare Chipkarte hat. Damit läßt sich das Kartenlesegerät 10 beispielsweise in das Bedienfeld eines Geldautomaten integrieren, ohne daß das ganze Bedienfeld geändert, insbesondere vergrößert werden muß.The dimensions of a front plate 68 of the card reading device 10 are equal to the dimensions of a front plate of a card reading device which has only one reading device for an exchangeable chip card. The card reader 10 can thus be integrated into the control panel of an ATM, for example, without the entire control panel having to be changed, in particular enlarged.
Durch die Erfindung wird eine Vorrichtung zum gleichzeitigen Bearbeiten mehrerer wechselbarer Chipkarten bereitgestellt, die platzsparend, sicher und leicht zu bedienen ist. Im Vergleich zu der beim Stand der Technik verwendeten Kombination aus zwei Kartenlesegeräten, die jeweils eine wechselbare Chipkarte bearbeiten, werden durch die Erfindung Herstellungskosten gesenkt, weil Komponenten, wie z.B. der Magnetlesekopf 60, nur einmal vorhanden zu sein brauchen. The invention provides a device for the simultaneous processing of several exchangeable chip cards, which is space-saving, safe and easy to use. Compared to the combination of two card readers used in the prior art, each of which processes an exchangeable chip card, the invention reduces manufacturing costs because components such as e.g. the magnetic reading head 60 need only be present once.
