The write and/or read contacts (10, ..., 17) contact corresponding rigid matching contacts (20, ..., 27) of a card reader with a chip card (1) reception shaft. The contacts (10, ..., 17) are designed in such a way that contact is maintained when the chip card (1) is moved beyond its normal position, in particular when it is inserted into the card reception shaft, during the time required to end a writing operation when the chip card (1) is removed from the card reception shaft and/or when the chip card (1) is moved in or across its insertion direction into the card reader, in particular when the chip card (1) is inserted into or withdrawn from the card reader. The contacts (10, ..., 17) are designed in such a way that no short-circuit is produced between individual contacts (10, ..., 17) when the matching contacts (20, ..., 27) pass over the contacts (10, ..., 17). A chip card reader has a chip card (1) reception shaft and matching contacts (20, ..., 27) that mechanically cooperate with write and/or read contacts (10, ..., 17) on the chip card (1) and that electrically connect a computer to the contacts (10, ..., 17). The matching contacts (20, ..., 27) are rounded in and/or across the insertion direction of the chip card (1) into the card reader. The curvature radius is selected in such a way that no short-circuit is produced between individual contacts (10, ..., 17) when the matching contacts (20, ..., 27) pass over the contacts (10, ..., 17) of the chip card (1).

Description

Chipkartβ und Kartenleser für ChipkartenChip card and card reader for chip cards
Stand der TechnikState of the art
Die Erfindung geht von einer Chipkarte nach der Gattung des unabhängigen Anspruchs 1 und von einem Kartenleser für Chipkarten nach der Gattung des unabhängigen Anspruchs 6 aus.The invention is based on a chip card according to the category of independent claim 1 and on a card reader for chip cards according to the category of independent claim 6.
Aus der noch nicht vorveröffentlichten deutschen Patentanmeldung 19 501 620 ist ein Kartenleser für Chipkarten bekannt, der eine Kontaktanordnung mit Kontakten umfaßt, die bei im Kartenschacht des Kartenlesers arretierter Chipkarte mit den Kontakten des Mikrochips der Chipkarte elektrisch leitend verbunden sind. Die Kontakte der Kontaktanordnung sind in Einschubrichtung der Chipkarte so weit verlängert, daß die Verbindung mit den Kontakten auf der Chipkarte auch dann noch aufrechterhalten ist, wenn die Entnahme der Chipkarte eingeleitet ist.From the as yet unpublished German patent application 19 501 620 a card reader for chip cards is known which comprises a contact arrangement with contacts which are electrically conductively connected to the contacts of the microchip of the chip card when the chip card is locked in the card slot of the card reader. The contacts of the contact arrangement are extended so far in the direction of insertion of the chip card that the connection with the contacts on the chip card is maintained even when the removal of the chip card has been initiated.
Vorteile der Erfindung Die erfindungsgemäße Chipkarte mit den Merkmalen des unabhängigen Anspruchs 1 hat demgegenüber den Vorteil, daß durch entsprechende Ausbildung der Kontakte auf der Oberfläche der Chipkarte eine Verlängerung der Gegenkontakte des Kartenlesers nicht erforderlich ist und dennoch dieAdvantages of the invention The chip card according to the invention with the features of independent claim 1 has the advantage that an extension of the counter contacts of the card reader is not necessary by appropriate design of the contacts on the surface of the chip card and still
Kontaktierung bei Entnahme der Chipkarte für eine gewisse Zeit, die zur Beendigung eines noch aktiven Schreibvorganges ausreicht, aufrechterhalten ist. Auf diese Weise wird Aufwand und Material bei der Herstellung der Gegenkontakte eingespart. In der Regel sind die Kontakte elektrisch leitend mit einem Mikrochip verbunden, den die Chipkarte enthält . Dabei erstrecken sich die Kontaktflächen aus Designgründen meist über die gesamte Ausdehnung des entsprechenden Chipmoduls auf der Oberfläche der Chipkarte. Nichtbenötigte Kontaktflachen sind dabei beispielsweise mit dem Bezugspotential verbunden. Die erfindungsgemäße Ausbildung der Kontakte erfordert also lediglich eine entsprechende Aufteilung der Kontaktflachen auf der Oberfläche der Chipkarte und stellt keinen Mehraufwand im Vergleich zur herkömmlichen Aufteilung der Kontaktflächen dar.Contacting when the chip card is removed is maintained for a certain time, which is sufficient for the end of a still active writing process. In this way, effort and material are saved in the production of the counter contacts. As a rule, the contacts are electrically conductively connected to a microchip which the chip card contains. For design reasons, the contact areas usually extend over the entire extent of the corresponding chip module on the surface of the chip card. Contact surfaces that are not required are connected to the reference potential, for example. The design of the contacts according to the invention therefore only requires a corresponding division of the contact areas on the surface of the chip card and does not represent any additional effort in comparison to the conventional division of the contact areas.
Als weiterer Vorteil ist anzusehen, daß durch die entsprechende Ausbildung der Kontakte Datentransfers zwischen der Chipkarte und dem Kartenleser nicht nur beim Entnehmen der Chipkarte, sondern auch beim Einschieben und einem damit verbundenen Überhub, sowie bei Bewegungen der Chipkarte quer zur Richtung der Einführung der Chipkarte in den Kartenleser, störungsfrei durchgeführt bzw. zu Ende gebracht werden können.Another advantage is that the appropriate design of the contacts transfers data between the chip card and the card reader not only when the chip card is removed, but also when it is inserted and an associated overstroke, and when the chip card moves transversely to the direction of insertion of the chip card the card reader can be carried out without problems or brought to completion.
Durch die in den Ansprüchen 2 bis 5 aufgeführten Maßnahmen sind vorteilhafte Weiterbildungen und Verbesserungen der im unabhängigen Anspruch 1 angegebenen Chipkarte möglich. Vorteilhaft gemäß Anspruch 2 ist die Ausbildung der Kontakte so, daß es beim Überstreichen der Kontakte durch die Gegenkontakte zu keinem Kurzschluß zwischen einzelnen Kontakten kommt. Dadurch wird verhindert, daß es zu Datenverlusten oder zur Zerstörung des Mikrochips oder von elektronischen Bauteilen des Kartenlesers durch Kurzschluß kommt.Advantageous further developments and improvements of the chip card specified in independent claim 1 are possible through the measures listed in claims 2 to 5. Advantageous according to claim 2, the formation of the contacts so that there is no short circuit between individual contacts when the contacts are swept by the counter contacts. This prevents data loss or the microchip or electronic components of the card reader being destroyed by a short circuit.
Der erfindungsgemäße Kartenleser mit den Merkmalen des unabhängigen Anspruchs 6 hat den Vorteil, daß durchThe card reader according to the invention with the features of independent claim 6 has the advantage that
Abrundung der Gegenkontakte in und/oder quer zur Richtung der Einführung der Chipkarte in den Kartenleser die Einführung und die Entnahme der Chipkarte nicht durch die Gegenkontakte blockiert werden kann.Rounding the counter contacts in and / or transversely to the direction of the insertion of the chip card into the card reader, the insertion and removal of the chip card cannot be blocked by the counter contacts.
Als weiterer Vorteil ist anzusehen, daß die Auflagefläche der Gegenkontakte auf der Chipkarte bzw. den Kontakten der Chipkarte verringert wird und auf diese Weise ein kleinerer Abstand zwischen den Kontakten auf der Chipkarte realisierbar ist, ohne daß es beim Überstreichen derAnother advantage is that the contact surface of the counter contacts on the chip card or the contacts of the chip card is reduced and in this way a smaller distance between the contacts on the chip card can be realized without it being covered by the
Kontakte der Chipkarte durch die Gegenkontakte zu einem Kurzschluß kommt. Durch die auf diese Weise ermöglichte weitere Verlängerung der Kontaktflachen kann die Kontaktierung beim Einschieben oder Entnehmen der Chipkarte noch länger aufrechterhalten werden.Contacts of the chip card through the counter contacts comes to a short circuit. Due to the further extension of the contact surfaces made possible in this way, the contact can be maintained even longer when the chip card is inserted or removed.
Durch die in den Ansprüchen 7 und 8 aufgeführten Maßnahmen sind vorteilhafte Weiterbildungen und Verbesserungen des im unabhängigen Anspruch 6 angegebenen Kartenlesers möglich.The measures listed in claims 7 and 8 allow advantageous developments and improvements of the card reader specified in independent claim 6.
Vorteilhaft nach Anspruch 7 ist die Abstimmung des Rundungsradius für die Gegenkontakte auf die Abmessungen und Abstände der Kontakte der Chipkarte. Auf diese Weise werden Kurzschlüsse zwischen einzelnen Kontakten und damit Datenverluste bzw. die Zerstörung des Mikrochips oder von elektronischen Bauteilen des Kartenlesers verhindert.Advantageous according to claim 7 is the matching of the radius of curvature for the counter contacts to the dimensions and distances of the contacts of the chip card. In this way, short circuits between individual contacts and thus Data loss or the destruction of the microchip or electronic components of the card reader prevented.

Beschreibung des AusführungsbeispielsDescription of the embodiment
In Figur 1 kennzeichnet 1 eine Chipkarte mit einem Mikrochipmodul 5. Auf der Oberfläche der Chipkarte 1 sind im Bereich des Mikrochipmoduls 5 acht Kontakte 10, 11, 12, 13, 14, 15, 16, 17 angebracht und elektrisch leitend mit dem Mikrochip verbunden. Sie dienen zur Kontaktierung von entsprechenden starren acht Gegenkontakten 20, ...., 27 eines Kartenlesers mit einem Kartenschacht zur Aufnahme der Chipkarte 1. In Figur 1 ist die Kontaktierung des ersten und des achten Kontaktes 10 und 17 der Chipkarte 1 mit dem ersten und dem achten Gegenkontakt 20 und 27 des Kartenlesers dargestellt. Die Gegenkontakte 20, 27 sind elektrisch leitend mit einem Mikroprozessor 40 des Kartenlesers verbunden. Die Kontakte 10, ..., 17 auf der Oberfläche der Chipkarte 1 sind so angeordnet, daß in der durch einen Pfeil gekennzeichneten Einschubrichtung jeweils zwei Kontakte und quer zur Einschubrichtung jeweils vier Kontakte nebeneinander angeordnet sind. Gemäß Figur 1 wird die Chipkarte 1 der Länge nach in den Kartenschacht des Kartenlesers eingeführt. Es ist aber auch denkbar, die Chipkarte 1 der Breite nach in einen entsprechenden Kartenschacht einzuführen. In diesem Fall müßte die Anordnung der Kontakte 10, ..., 17 auf der Oberfläche derIn FIG. 1, 1 denotes a chip card with a microchip module 5. Eight contacts 10, 11, 12, 13, 14, 15, 16, 17 are attached to the surface of the chip card 5 in the area of the microchip module 5 and are connected to the microchip in an electrically conductive manner. They serve for contacting corresponding rigid eight counter-contacts 20,..., 27 of a card reader with a card slot for receiving the chip card 1. In FIG. 1, the contacting of the first and eighth contacts 10 and 17 of the chip card 1 with the first and the eighth mating contact 20 and 27 of the card reader. The counter contacts 20, 27 are electrically conductively connected to a microprocessor 40 of the card reader. The contacts 10, ..., 17 on the surface of the chip card 1 are arranged in such a way that two contacts are arranged in the insertion direction indicated by an arrow, and four contacts are arranged next to one another transversely to the insertion direction. According to Figure 1 the chip card 1 is inserted lengthways into the card slot of the card reader. However, it is also conceivable to insert the chip card 1 into a corresponding card slot. In this case, the arrangement of the contacts 10, ..., 17 on the surface of the
Chipkarte 1 im Vergleich zur Darstellung der Figur 1 um 90° gedreht werden. Es soll im folgenden keine Rolle spielen, ob die Chipkarte 1 der Länge oder der Breite nach in einen Kartenschacht einzuführen ist, da die Anordnung der Kontakte 10, -.., 17 in Einschubrichtung immer dieselbe ist. Durch die Kontaktierung der Kontakte 10, ..., 17 mit den entsprechenden Gegenkontakten 20, ..., 27 sind mit Hilfe des Mikroprozessors 40 Schreib- und/oder Lesevorgänge auf dem Mikrochip der Chipkarte 1 möglich.Chip card 1 can be rotated by 90 ° in comparison to the illustration in FIG. It should not matter in the following whether the chip card 1 is to be inserted lengthwise or widthwise into a card slot, since the arrangement of the contacts 10,..., 17 in the direction of insertion is always the same. By contacting the contacts 10, ..., 17 with the corresponding mating contacts 20, ..., 27, the microprocessor 40 enables 40 writing and / or reading operations on the microchip of the chip card 1.
Die in Figur 1 schematisch dargestellte Kontaktierung ist in Figur 2 realistischer dargestellt. In Figur 2 ist erkennbar, daß die Gegenkontakte 20, ..., 27 abgerundet sind. Die Figur 2 stellt drei Positionen der Chipkarte 1 beim Einführen in den Kartenschacht des Kartenlesers dar. In der oberen Darstellung A wird die Chipkarte 1 in Pfeilrichtung in den Kartenschacht eingeführt, und die Gegenkontakte 20, ..., 27 berühren bereits die Kontakte 10, ..., 17, obwohl die Chipkarte 1 eine Endposition 50 im Kartenschacht des Kartenlesers noch nicht erreicht hat. Auf diese Weise können bereits erste Daten ausgetauscht werden, beispielsweise Daten, die dem Mikroprozessor 40 des Kartenlesers den Beginn der Kontaktierung signalisieren. Der Mikroprozessor 40 kann dann weitere Schreib- und/oder Lesevorgänge einleiten. Aufgrund der Länge der KontakteThe contacting shown schematically in FIG. 1 is shown more realistically in FIG. In Figure 2 it can be seen that the counter contacts 20, ..., 27 are rounded. FIG. 2 shows three positions of the chip card 1 when it is inserted into the card slot of the card reader. In the upper illustration A, the chip card 1 is inserted into the card slot in the direction of the arrow, and the mating contacts 20,..., 27 already touch the contacts 10, ..., 17, although the chip card 1 has not yet reached an end position 50 in the card slot of the card reader. In this way, first data can already be exchanged, for example data which signal the microprocessor 40 of the card reader that contact has started. The microprocessor 40 can then initiate further writing and / or reading processes. Because of the length of the contacts
10, ..., 17 bleibt die Kontaktierung bis zum Anschlag der Chipkarte 1 am Schachtboden 45 des Kartenlesers gemäß Kartenstellung B der Figur 2 aufrechterhalten. Dabei befindet sich die Chipkarte 1 in einer Überhubsteilung, da der Schachtboden 45 nicht der Endposition 50 entspricht und die Chipkarte 1 beispielsweise durch eine am Schachtboden 45 angebrachte Feder in die Endposition 50 zurückgedrückt wird. Die Chipkarte 1 befindet sich dann in der Kartenstellung C der Figur 2 und die Kontaktierung der Gegenkontakte 20, ..., 27 mit den Kontakten 10, ..., 17 ist mittig. Wird die Chipkarte 1 während eines Schreibvorgangs aus dem Kartenleser entnommen, so muß für eine zur Beendigung des Schreibvorgangs erforderliche Zeit die Kontaktierung aufrechterhalten werden, da sonst Datenverlust droht. Der Schreibvorgang dauert maximal 50 Millisekunden. Bei ausreichender Länge der Kontakte 10, ..., 17 kann die Kontaktierung bis zur Beendigung des Schreibvorgangs aufrechterhalten werden. Auf diese Weise muß der Schreibvorgang beim Entnehmen der Chipkarte 1 aus dem Kartenschacht spätestens dann beendet sein, wenn die10, ..., 17 the contacting is maintained until the chip card 1 stops on the slot bottom 45 of the card reader according to card position B in FIG. In this case, the chip card 1 is in an overstroke division, since the shaft bottom 45 does not correspond to the end position 50 and the chip card 1 is pushed back into the end position 50, for example by a spring attached to the shaft bottom 45. The chip card 1 is then in the card position C in FIG. 2 and the contacting of the mating contacts 20, ..., 27 with the contacts 10, ..., 17 is in the center. If the chip card 1 is removed from the card reader during a write process, the contact must be maintained for a period of time required to complete the write process, since otherwise there is a risk of data loss. The write process takes a maximum of 50 milliseconds. If the contacts 10,..., 17 are of sufficient length, contact can be maintained until the writing process has ended. In this way, the writing process must be completed when the chip card 1 is removed from the card slot at the latest when the
Chipkarte 1 die Kartenstellung A der Figur 2 eingenommen hat.Chip card 1 has assumed card position A of FIG. 2.
Da die Abmessungen des Kartenschachtes für eine bequeme Karteneingabe und -ausgäbe breiter sein muß als die Chipkarte 1, kann es vor allem beim Einschieben oder Entnehmen der Chipkarte 1 zu einem Kartenhub quer zur Einschubrichtung kommen. Eine solche Situation ist in Figur 3 dargestellt. Eine entsprechend quer zur Endposition 50 verlaufende seitliche Normalposition 55 der Chipkarte 1 imSince the dimensions of the card slot must be wider than the chip card 1 for convenient card input and output, a card stroke can occur transversely to the direction of insertion, especially when the chip card 1 is inserted or removed. Such a situation is shown in FIG. 3. A corresponding lateral perpendicular position 55 of the chip card 1 in the direction transverse to the end position 50
Kartenschacht des Kartenlesers kann durch den seitlichen Hub der Chipkarte 1 bis zum Anschlag an der Seitenwand 60 des Kartenschachtes überschritten werden. Eine solche Situation ist als Kartenstellung A in Figur 3 dargestellt. Die vier dargestellten Kontakte 10, ..., 13 haben aufgrund ihrerThe card slot of the card reader can be exceeded by the lateral stroke of the chip card 1 up to the stop on the side wall 60 of the card slot. Such a situation is shown as card position A in FIG. 3. The four contacts 10, ..., 13 shown have due to their
Breite trotz des seitlichen Hubes der Chipkarte 1 Kontakt mit den entsprechenden Gegenkontakten 20, ..., 23, so daß die Kontaktierung während dieses seitlichen Hubes aufrechterhalten wird. Bei Kartenstellung B gemäß Figur 3 hat die Chipkarte l ihre seitliche Normalposition 55 eingenommen und die Kontaktierung der Kontakte 10, ..., 13 mit den entsprechenden Gegenkontakten 20, ..., 23 erfolgt mittig.Width despite the lateral stroke of the chip card 1 contact with the corresponding mating contacts 20, ..., 23, so that the contact is maintained during this lateral stroke. In card position B according to FIG. 3, chip card 1 has its lateral normal position 55 taken and the contacting of the contacts 10, ..., 13 with the corresponding counter-contacts 20, ..., 23 takes place in the middle.
Figur 4 zeigt eine Einzelheit aus der Kartenposition A der Figur 2. Dabei ist der Abstand 30 in Einschubrichtung zwischen den beiden Kontakten 10 und 17 beispielhaft eingezeichnet. Dieser Abstand muß größer sein als die Ausdehnung der Gegenkontaktflache des entsprechenden Gegenkontakts 20, ..., 27 in derselben Richtung. Ansonsten kommt es beim Überstreichen der Kontakte 10, ..., 17 durch die Gegenkontakte 20, ..., 27 zum Kurzschluß zwischen einzelnen Kontakten 10, ..., 17. Ein solcher Kurzschluß kann zu Datenverlust oder gar zur Zerstörung des Mikrochips und/oder des Mikroprozessors 40 führen.Figure 4 shows a detail from the card position A of Figure 2. The distance 30 in the insertion direction between the two contacts 10 and 17 is shown as an example. This distance must be greater than the extent of the mating contact surface of the corresponding mating contact 20, ..., 27 in the same direction. Otherwise there is a short circuit between individual contacts 10, ..., 17 when the contacts 10, ..., 17 are swept by the counter contacts 20, ..., 17. Such a short circuit can lead to data loss or even destruction of the microchip and / or the microprocessor 40.
Figur 5 zeigt eine Einzelheit der Kartenstellung A gemäß Figur 3. Dargestellt ist der Abstand 35 zwischen den beiden Kontakten 12 und 13 , die quer zur Richtung der Einführung der Chipkarte 1 in den Kartenleser benachbart sind. DieserFIG. 5 shows a detail of the card position A according to FIG. 3. The distance 35 between the two contacts 12 and 13 is shown, which are adjacent transversely to the direction in which the chip card 1 is inserted into the card reader. This
Abstand muß größer sein als die Ausdehnung der Gegenkontaktflache des entsprechenden Gegenkontaktes 20, ..., 27 in derselben Querrichtung. Ansonsten kommt es beim Überstreichen der Kontakte 10, ... , 17 durch die Gegenkontakte 20, ..., 27 zum Kurzschluß zwischen einzelnen Kontakten 10, ..., 17. Ein damit eventuell verbundener Datenverlust oder die Zerstörung des Mikrochips und/oder des Mikroprozessors 40 soll jedoch verhindert werden.Distance must be greater than the extent of the mating contact surface of the corresponding mating contact 20, ..., 27 in the same transverse direction. Otherwise, when the contacts 10, ..., 17 are swept by the counter-contacts 20, ..., 27, there is a short circuit between individual contacts 10, ..., 17. Any data loss associated therewith or the destruction of the microchip and / or of the microprocessor 40 is, however, to be prevented.
Zur Verhinderung der genannten Kurzschlüsse sind dieTo prevent the short circuits mentioned, the
Abmessungen der Kontakte 10, ..., 17 und die Rundungsradien der Gegenkontakte 20, ..., 27 aufeinander abzustimmen. Dabei sind die Gegenkontakte 20, ..., 27 auch quer zur Richtung der Einführung der Chipkarte 1 in den Kartenleser abgerundet, so daß es auch quer zur Richtung der Einführung der Chipkarte 1 nicht zur Blockade der Chipkarte 1 im Kartenschacht des Kartenlesers kommt.

Abmessungen ist in Figur 6 die Einzelheit aus Figur 4 weiter vergrößert. In Figur 6 kennzeichnet 65 den Rundungsradius für die Abrundung der Gegenkontakte 20, ..., 27 in Einschubrichtung der Chipkarte 1 beispielhaft am achten Gegenkontakt 27. Dabei liegt in Abänderung der Einzelheit aus Figur 4 der achte Gegenkontakt 27 genau in der Mitte zwischen den beiden in Einschubrichtung benachbarten Kontakten 10 und 17 auf der Oberfläche 80 der Chipkarte 1 auf, ohne die beiden Kontakte 10 und 17 zu berühren. Die Oberfläche 80 der Chipkarte 1 bestimmt somit das6, the detail from FIG. 4 is further enlarged. In FIG. 6, 65 denotes the rounding radius for the rounding of the counter contacts 20,... 27 in the insertion direction of the chip card 1, for example on the eighth counter contact 27. The eighth counter contact 27 is in a variation of the detail from FIG. 4, exactly in the middle between the two in the direction of insertion adjacent contacts 10 and 17 on the surface 80 of the chip card 1 without touching the two contacts 10 and 17. The surface 80 of the chip card 1 thus determines this
Auflageniveau der Gegenkontakte 20, ..., 27. Zwischen der Oberfläche 85 der Kontakte 10, ..., 17 und der Oberfläche 80 der Chipkarte 1 besteht ein Abstand 75. Bei einem zulässigen höchsten Abstand 75 zwischen der Oberfläche 85 der Kontakte 10, ..., 17 und der Oberfläche 80 der Chipkarte 1 vonSupport level of the mating contacts 20, ..., 27. There is a distance 75 between the surface 85 of the contacts 10, ..., 17 and the surface 80 of the chip card 1. At a maximum permissible distance 75 between the surface 85 of the contacts 10, ... ..., 17 and the surface 80 of the chip card 1 from

Dabei wird für den Abstand 30 zwischen Kontakten 10, ..., 17, die in Richtung der Einführung der Chipkarte 1 in den Kartenleser benachbart sind, beispielsweise ein Wert von 0,8 mm oder 1 mm gewählt. Der gewählte Abstand ist in Figur 6 mit dem Bezugszeichen 31 gekennzeichnet.0.018 mm and a radius of curvature in the direction of the insertion of the chip card 1 of at most 3.3 mm, the distance 30 between contacts 10, ..., 17, which are adjacent in the direction of the insertion of the chip card 1 into the card reader, must be greater than 0, Be 69 mm so that there is no short circuit when the contacts 10, ..., 17 are swept by the counter-contacts 20, ..., 27 between the individual contacts 10, ..., 17. For the distance 30 between contacts 10,..., 17, which are adjacent in the direction of the insertion of the chip card 1 into the card reader, a value of 0.8 mm or 1 mm is selected, for example. The selected distance is identified in FIG. 6 by the reference symbol 31.
In Figur 7, die eine weitere Vergrößerung der Einzelheit aus Figur 5 darstellt, kennzeichnet 70 den Rundungsradius der Gegenkontakte 20, ..., 27 quer zur Richtung der Einführung der Chipkarte 1 in den Kartenleser. In Abänderung der Einzelheit aus Figur 5 liegt der dritte Gegenkontakt 22 genau in der Mitte zwischen den beiden quer zurIn FIG. 7, which represents a further enlargement of the detail from FIG. 5, 70 denotes the radius of curvature of the counter-contacts 20,..., 27 transverse to the direction of the insertion of the chip card 1 into the card reader. In a modification of the detail from FIG. 5, the third counter contact 22 lies exactly in the middle between the two transverse to

Kontakte 10, ..., 17 durch die Gegenkontakte 20, ..., 27 zwischen einzelnen Kontakten 10, ..., 17 auftritt. Dabei wird beispielsweise für den Abstand 35 zwischen Kontakten 10, ..., 17, die quer zur Einschubrichtung benachbart sind, ein Wert von 0,6 mm gewählt. Dieser gewählte Abstand ist in Figur 7 durch das Bezugszeichen 36 gekennzeichnet.Contacts 10, ..., 17 through the counter-contacts 20, ..., 27 between individual contacts 10, ..., 17 occurs. For example, a value of 0.6 mm is selected for the distance 35 between contacts 10,... 17, which are adjacent transversely to the direction of insertion. This selected distance is identified in FIG. 7 by reference number 36.
Damit die Kontaktierung während eines beim Einschieben oder Entnehmen der Chipkarte 1 auftretenden Überhubs und/oder während einer zur Beendigung eines Schreibvorgangs erforderlichen Zeit beim Entnehmen der Chipkarte 1 aus dem Kartenschacht und/oder während eines quer zur Richtung der Einführung der Chipkarte 1 in den Kartenleser auftretenden Hubes, beim Einschieben, Entnehmen oder sonstiger Bewegung der Chipkarte im Kartenschacht aufrechterhalten werden kann, werden die Kontakte 10, ..., 17 in Richtung der Einführung der Chipkarte 1 in den Kartenleser länger als 5,5 mm und quer zur Richtung der Einführung der Chipkarte 1 in den Kartenleser breiter als 1,9 mm ausgeführt. Begrenzt werden die Abmessungen der Kontakte durch die Größe des Mikrochipmoduls 5. So sind bei einem Mikrochipmodul 5 der Länge 13 mm in Einschubrichtung und der Breite 10 mm quer zur Einschubrichtung Kontakte 10, ..., 17 der Länge 6 mm in Einschubrichtung und der Breite 1,94 mm quer zur Einschubrichtung realisierbar. Thus, the contacting during an overstroke and / or occurring when the chip card 1 is inserted or removed can be maintained during a time required to complete a writing process when the chip card 1 is removed from the card slot and / or during a stroke occurring transversely to the direction of the insertion of the chip card 1 into the card reader, during insertion, removal or other movement of the chip card, the contacts 10, ..., 17 are made longer than 5.5 mm in the direction of the insertion of the chip card 1 into the card reader and wider than 1.9 mm transversely to the direction of the insertion of the chip card 1 in the card reader. The dimensions of the contacts are limited by the size of the microchip module 5. Thus, in the case of a microchip module 5, the length is 13 mm in the direction of insertion and the width is 10 mm transverse to the direction of insertion, contacts 10,... 17, length 6 mm in the direction of insertion and the width 1.94 mm can be realized across the direction of insertion.
