Die Erfindung geht aus von einem Verfahren bzw. einer Vorrichtung nach der Gattung der unabhängigen Ansprüche, wie sie aus der Deutschen Patentanmeldung DE-A-19703998 bekannt sind. Darin ist eine aus einer Basisstation sowie mehreren zugeordneten Betätigungselementen bestehende Fernwirkeinrichtung beschrieben, welche beispielsweise die rechtmäßige Benutzung eines Kraftfahrzeuges sicherstellt. Die Einrichtung gestattet auch das Neuzuordnen weiterer Betätigungselemente zu der Basisstation. Unter der Voraussetzung, daß ein bestimmtes, als Hauptbetätigungselement fungierendes Betätigungselement anwesend ist, überträgt dabei die Basisstation einem neu zuzuordnenden Betätigungselement eine Zuordnungsinformation in Form einer Seriennummer, eines kryptischen Schlüsselcodes sowie einer von der Basisstation jeweils neu vergebenen Gruppennummer. Nicht an ein neuzugeordnetes Betätigungselement übertragen werden Zusatzinformationen, welche den Funktionsumfang des Betätigungselementes weiter bestimmen. Sie bleiben nur erhalten, soweit sie in der Basisstation einer Gruppennummer zugeordnet sind, und diese Gruppennummer an.das neu zuzuordnende Betätigungselement vergeben wird. In der Regel sind die Zusatzinformationen in einem neuzugeordneten Betätigungselement neu bekanntzumachen. Das bekannte Verfahren bzw. die bekannte Vorrichtung ermöglichen daher nicht ohne weiteres die Herstellung eines mit einem vorhandenen funktional identisch übereinstimmenden Betätigungselementes.The invention is based on a method or a device according to the genre of independent claims, as from German patent application DE-A-19703998 are known. Inside is one from a base station as well as several associated actuators Telecontrol device described, for example ensures the lawful use of a motor vehicle. The facility also allows the remapping of others Actuators to the base station. Under the Prerequisite that a specific, as the main operating element operating actuator is present, transmits the base station a reassignable actuator assignment information in the form of a serial number, a cryptic key code and one of the Base station each newly assigned group number. Not on a reassigned actuator is transmitted additional information, which the functional scope of the actuator determine further. They only remain as far as they are assigned to a group number in the base station and this group number to the reallocated Actuator is assigned. As a rule, the additional information in a reassigned actuator to make new known. The known method or Known devices therefore do not easily allow making one functionally identical to an existing one matching actuator.

Aus der WO 94/16415 ist ein täuschungssicheres Kreditkartenverwaltungssystem bekannt, bestehend aus einem Kartenleser für Kreditkarten und einem Zentralrechner. Dieses System gestattet eine neuzuzuordnende Kreditkarte mit Hilfe einer alten Kreditkarte freizugeben. Dabei kann wahlweise die neuzuzuordnende und die bereits zugeordnete Kreditkarte als erste eingegeben werden. Das Freigeben bzw. das Sperren der jeweiligen Kreditkarte findet im Zentralcomputer und nicht auf der Kreditkarte statt, wobei die Identifizierungsdaten der neuen und alten Karte verschieden sind.WO 94/16415 is a deception-proof credit card management system known, consisting of a card reader for credit cards and a central computer.

Aus der US-A-5,231,273 ist ein System bekannt, welches einen Transponder, eine Abfrageeinheit und hiermit verbundene Steuereinrichtungen umfaßt. Die Abfrageeinheit ermittelt Transponder mit schwachen Batterien. Der Transponder bestimmt hierzu die Qualität seiner Batterie und antwortet der Abfrageeinheit, wenn die Batterie schwach ist. Dann wird eine Wartungsanweisung gegeben, um den Transponder zu ersetzen.From US-A-5,231,273 a system is known which one Transponder, an interrogation unit and related Controls includes. The query unit determines Transponder with weak batteries. The transponder determines the quality of his battery and answers the Interrogation unit when the battery is low. Then one Maintenance instructions given to replace the transponder.

Fernwirkeinrichtungen, wie zuvor genannte, benutzen für die Kommunikation ein niederfrequentes Feld von z. B. 150 kHz. Gewünscht ist eine Kommunikationsreichweite von mindestens 1,5 m. Diese Reichweite läßt sich nur erzielen, wenn das Betätigungselement mit einer Batterie zur Unterstützung des Sendens/Empfangens ausgestattet ist. Ohne Batterie liegt die Kommunikationsreichweite im Bereich einiger Zentimeter. Ein Trend in der Ausgestaltung der Betätigungselemente geht dahin, sie als Transponder in sogenannten Smartkarten mit integrierter, flächiger Batterie auszubilden. Die Batterie ist dabei nicht auswechselbar. Ist sie leer, wird vielmehr die gesamte Smartkarte durch eine neue ersetzt.Telecontrol devices, such as those mentioned above, are used for the Communication a low frequency field of e.g. B. 150 kHz. A communication range of at least is desirable 1.5 m. This range can only be achieved if the actuating element with a battery to support the Sending / receiving is equipped. It lies without a battery Communication range in the range of a few centimeters. On The trend in the design of the actuating elements is them as transponders in so-called smart cards with integrated, to train flat batteries. The battery is not interchangeable. If it is empty, it becomes entire smart card replaced by a new one.

Die Aufgabe wird gelöst durch ein Verfahren bzw. eine Vorrichtung mit den Merkmalen der unabhängigen Ansprüche. Erfindungsgemäß sind die im Betätigungselement abgelegten Informationen vollständig auslesbar, jedoch nur einmal. Nach erfolgreichem Auslesen wird ein erneutes Auslesen durch eine nichtaufhebbare Sperre unterbunden. Vorteilhaft werden die von einem zu ersetzenden Betätigungselement zu übernehmenden Zuordnungs-Informationen zunächst an die Basisstation übergeben und in einem flüchtigen Speicher zwischengespeichert. Anschließend werden sie an das neu zuzuordnende Betätigungselement übertragen. Dadurch vereinfacht sich die Durchführung des Neuzuordnungsvorganges, da nur das zu ersetzende Betätigungselement im Falle einer leeren Batterie in die unmittelbare Nähe der Basisstation zu bringen ist. Ein Duplizieren eines Betätigungselementes ist nur unter der Bedingung möglich, daß sich nur ein neuzuzuordnendes Betätigungselement im Reichweitenbereich der Basisstation befindet. Das Sperren des zu ersetzenden Betätigungselementes gegen erneutes Auslesen kann in einfacher Weise softwaremäße in Form eines dann zu setzenden Stopbits realisiert sein. Alternativ oder ergänzend kann auch eine elektronische Lösung vorgesehen sein, etwa in Form einer Schmelzdrahtsicherung. Das Duplizieren eines Betätigungselementes ist ferner nur zulässig, wenn die richtige Zuordnung des zu ersetzenden Betätigungselementes durch eine Codesicherheitsprüfung überprüft wurde.The object is achieved by a method or a device with the features of the independent claims.

Neben den auf die zugehörige Basisstation abgestimmten Zuordnungsfunktionen können solche Kartentransponder weitere Nutzungsinformationen enthalten, die etwa den mit dem Kartentransponder eingeräumten Funktionsumfang beim Gebrauch der der Basisstation zugehörigen technischen Einrichtung beschränken. Bei Verwendung in einem Kraftfahrzeug kann etwa der Aktionsbereich beschränkt sein. Desweiteren können die Kartentransponder mit der Basisstation nichtverkoppelte Informationen enthalten, welche den Transponder beispielsweise zugleich zu einem Zugangssystem für ein Haus machen.A telecontrol system according to the invention advantageously uses Wise transponders that are in smart cards in credit card format are realized.

Die Seriennummer 16 ist ein für die aus Basisstation 10 und zugehörigen Transpondern 40 bestehende Fernwirkeinrichtung charakteristischer Code und identisch mit der Seriennummer 16 im Speicher 15 der Basisstation 10. Die Gruppennummer 28 dient zur Unterscheidung von diesselbe Seriennummer 16 aufweisenden Transpondern 40. Sie wird bei der Nutzung der Fernwirkeinrichtung durch den Anwender festgelegt. Der Gerätecode 27 wird durch den Hersteller des Transponders 40 vergeben und bezeichnet ihn eindeutig. Der kryptische Schlüsselcode 31 ist identisch mit dem in der Basisstation 10 abgelegten kryptischen Schlüsselcode 31 und dient der Verifikation der Zugehörigkeit zu einer Basisstation 10. The signal processing of the transponder 40 is by a Evaluation circuit 20 realized, which is expedient in the form of a Chips is running. It has one on the base station side Transmitting / receiving device 11 corresponding Transceiver 21 for receiving from the Base station 10 emitted signals or for emitting signals to the base station 10. With the transmitting / receiving device 21 is connected to a reading lock device 22. It includes means 24 for permanent interruption sending data from the transponder 40 to Base station 10. The means 24 can be used as a software solution be implemented, for example in the form of a stop bit, which, if it is set, the transmission of data by the read interlock 22 to the transceiver 21 prevented. As an alternative or in addition, the means 24 can be physical for example in the form of a fuse his. The reading lock device 22 is connected downstream a microprocessor 23. It evaluates via the transceiver 21 incoming signals, depending on follow up on the results and prompted the output of output signals to the base station 10. Der Microprocessor 23 continues to operate in the reading lock device 22 arranged locking means 24. The microprocessor A non-volatile memory unit is assigned to 23 25. It includes the mapping information in memory 15 of the base station 10 complementary assignment information. The storage unit 25 therefore contains a storage space for storing a serial number 16, a storage space for storing a device code 27, a storage space for storing a group number 28, a storage space for Storage of a cryptic key code 31 and a storage space for storing usage information 29. The meaning the memory contents correspond to the meaning the similar memory contents in the memory 15 of the base station 10. Serial number 16 is one for the out base station 10 and associated transponders 40 existing telecontrol device characteristic code and identical to the serial number 16 in the memory 15 of the base station 10. Die Group number 28 is used to differentiate from the same serial number 16 transponders 40. It is used at the Use of the telecontrol device determined by the user. Device code 27 is provided by the transponder manufacturer 40 forgive and clearly identified him. The cryptic Key code 31 is identical to that in the base station 10 stored cryptic key code 31 and serves verification of membership of a base station 10.

Er wird durch den Hersteller der der Basisstation 10 zugehörigen technischen Einrichtung festgelegt. In der Speichereinheit 25 können weiterhin zusätzliche Nutzungsinformationen 29 abgelegt sein. Sie können bei Verwendung in einem Kraftfahrzeug beispielsweise dessen Aktionsradius einschränken, oder benutzerspezifische Angaben zur Fahrzeugeinstellung enthalten. Auch können die Nutzungsinformationen 29 mit der Funktion der Fernwirkeinrichtung nicht unmittelbar verbundene Informationen umfassen, zum Beispiel Informationen, welche den Transponder 40 dazu befähigen, neben einer Kraftfahrzeugtür auch ein Garagentor oder eine Haustür zu öffnen.It is provided by the manufacturer of the base station 10 technical equipment. In the storage unit 25 may continue to use additional information 29 filed. You can use it in one For example, restrict the motor vehicle's radius of action, or user-specific information on vehicle settings contain. The usage information 29 can also be used the function of the remote control device is not directly connected Include information, for example information, which enable the transponder 40 next to a motor vehicle door also open a garage door or a front door.

Dem Mikroprozessor 13 ist weiterhin ein zweiter flüchtiger Speicher 14 zugeordnet. Er dient zur Zwischenaufnahme von von einem Transponder 40 ausgelesenen Zuordnungs- und Nutzungsinformationen.The microprocessor 13 is still a second volatile Memory 14 assigned. It serves as an intermediate admission of assignment and usage information read by a transponder 40.

Zwischen Basisstation 10 und Transponder 40 besteht eine Signalübertragungsstrecke 30 zur Übertragung berührungslos übertragbarer Signale zwischen der transponderseitigen Sende-/Empfangseinrichtung 21 und der basisstationsseitigen Sende-/Empfangseinrichtung 11. Von der basisstationsseitigen Sende-/Empfangseinrichtung 11 ausgehende Signale erreichen dabei gleichzeitig alle innerhalb ihrer Reichweite befindli chen Transponder 40. Als Signale werden zweckmäßig Infrarot-, Nieder- oder Hochfrequenzsignale eingesetzt.There is a between base station 10 and transponder 40 Signal transmission path 30 for contactless transmission transmissible signals between the transponder-side transceiver 21 and the base station side Transceiver 11. From the base station side Transceiver 11 reach outgoing signals at the same time everyone within their range Chen transponder 40. Infrared, Low or high frequency signals are used.

Figur 2 zeigt eine Realisierung eines Transponders 40 in Draufsicht. Der Transponder 40 ist dabei in einer flachen Plastikkarte in Scheckkartenformat realisiert. Die Sende-/Empfangseinrichtung 21 ist über diesen Kartentransponder in Form einer ovalen, das Kartenformat möglichst gut ausnützenden, gedruckten Flachbahnantenne 41 realisiert. Über Verbindungen 42 ist sie mit der als Chip ausgeführten Auswerteschaltung 20 verbunden. Mit der Auswerteschaltung 20 über weitere Zuleitungen 43 weiterhin verbunden ist eine flächig ausgeführte, gedruckte Batterie 44. Sie liefert die Energie zur Durchführung einer Kommunikation mit einer Basisstation 10 über eine große Reichweite. Der Kartentransponder 40 ist beidseitig mit einer nicht gezeigten Schutzschicht überzogen. Die Batterie 44 ist nicht auswechselbar. Ist sie leer, ist der gesamte Kartentransponder 40 durch einen neuen Transponder 40 gleicher Funktionalität mit geladener Batterie 44 zu ersetzen. Der zu ersetzende Transponder 40 wird dabei dupliziert.FIG. 2 shows a transponder 40 in Top view. The transponder 40 is in a flat Plastic card in credit card format realized. The transceiver 21 is in about this card transponder Oval shape, making the most of the card format, printed flat track antenna 41 realized. About connections 42 with the evaluation circuit implemented as a chip 20 connected. With the evaluation circuit 20 over further supply lines 43 continue to be connected is flat executed, printed battery 44. It supplies the energy to carry out communication with a base station 10 over a long range. The card transponder 40 is covered on both sides with a protective layer, not shown. The battery 44 cannot be replaced. Is it empty the entire card transponder 40 is replaced by a new one Transponder 40 of the same functionality with a charged battery 44 to replace. The transponder 40 to be replaced becomes duplicated in the process.

Nachfolgend wird der Ablauf eines Dupliziervorganges anhand des Flußdiagrammes, Figur 3, erläutert. Die Notwendigkeit, einen Transponder 40 zu duplizieren, wird aus dessen fehlender Funktionsfähigkeit bei Anwendung aus großer Entfernung offensichtlich. Der Ersatz eines offensichtlich nur noch über eine leere Batterie 44 verbundenden Transponders 40 wird daraufhin durch einen Benutzer manuell ausgelöst, etwa durch Betätigen eines Schalters, Schritt 100. Die Basisstation 10 prüft daraufhin, ob der Benutzer zum Duplizieren eines Transponders 40 berechtigt ist. Es werde hier angenommen, daß die Berechtigung zum Duplizieren eines Transponders 40 durch die Anwesenheit eines speziellen, als Hauptbetätigungselement ausgeführten Transponders 40, des sogenannten "redkeys" nachgewiesen werde. Die Basisstation 10 prüft daher, Schritt 102, ob sich der redkey in der Reichweite der Signalübertragungsstrecke 30 befindet. Ist das nicht der Fall, wird der Dupliziervorgang abgebrochen, Schritt 103. Ist der redkey anwesend, veranlaßt die Basisstation 10 den zu ersetzenden Transponder 40 durch Zusendung eines entsprechenden Steuersignales - Schritt 104 - über die Signalübertragungsstrecke 30 zur Prüfung seiner Batterie 44, Schritt 106. Der Transponder 40 antwortet durch Rücksendung einer Batteriestatusmeldung, Schritt 108. Ist der Transponder 40 danach zu duplizieren, unterzieht die Basisstation 10 den zu ersetzenden Transponder 40 einer Prüfung der Zugehörigkeit zur Basisstation 10, Schritt 110. Die Zugehörigkeitsprüfung erfolgt vorzugsweise im Wege des "Challenge-Response"-Verfahrens. Dabei sendet die Basisstation 10 dem geprüften Transponder 40 ein challenge-Signal in Form einer Zufallszahl. Durch Verknüpfung mit dem im Speicher 15 abgelegten kryptischen Schlüsselcode 31 und dem im Verzeichnis 18 abgelegten Gerätecode 27 des geprüften Transponders 40 bildet sie aus der Zufallszahl gleichzeitig ein Soll-Responsesignal. Auf die selbe Weise bildet währenddessen der Transponder 40 unter Zugriff auf die entsprechenden Informationen in der Speichereinheit 25 aus dem emfangenen Challengesignal ein Responsesignal, welches er sodann an die Basisstation 10 zurücksendet. Jene vergleicht es mit dem zuvor gebildeten Soll-Responsesignal und schließt bei Übereinstimmung auf Zugehörigkeit des Transponders 40 zur Basisstation 10. Ist die Zugehörigkeit des Transponders 40 zur Basisstation danach erwiesen, prüft die Basisstation 10, ob sich in der Reichweite der Signalstrecke 30 ein neuzuzuordnender, noch nicht auf die Basisstation 10 "angelernter" Transponder 40 befindet. Hierzu setzt sie ein offenes Identifizierungssignal ab, Schritt 112, das von in der Reichweite der Signalübertragungsstrecke 30 befindlichen neu zuzuordnenden Transpondern 40 empfangen wird. Alle anwesenden neu zuzuordnenden Transponder 40 antworten auf den Empfang eines offenen Identifizierungssignales durch Rücksendung eines Kontaktsignales an die Basisstation 10, Schritt 114. Jene führt daraufhin eine Vereinzelungsroutine durch, Schritt 116. Dabei werden, sofern mehrere neu zuzuordnende Transponder 40 anwesend sind, alle bis auf einen in einen Schlafmodus versetzt, in dem sie an der nachfolgenden Kommunikation nicht mehr teilnehmen. Nachdem ein einzelner neu zuzuordnender Transponder 40 feststeht, setzt die Basisstation 10 ein Signal ab, mittels dessen der zu ersetzende Transponder 40 aufgefordert wird, die in der Speichereinheit 25 abgelegten Informationen auszulesen und an die Basisstation 10 zu senden, Schritt 118. Der zu ersetzende Transponder 40 antwortet nach Erhalt eines Ausleseanforderungssignales entsprechend durch Rücksenden der in der Speichereinheit 25 abgelegten Informationen an die Basiseinheit 10, Schritt 120. Jene übernimmt sie über ihre Sende-/Empfangseinrichtung 11 und legt sie in den flüchtigen Speicher 14 ab, Schritt 122. Daraufhin unterzieht die Basisstation 10 den Transponder 40 erneut einer Zugehörigkeitsprüfung, Schritt 124. Sie kann wie die Zugehörigkeitsprüfung gemäß Schritt 110 erfolgen. Ist das Ergebnis der Zugehörigkeitsprüfung erneut positiv, sendet die Basisstation 10 dem zu ersetzenden Transponder 40 ein Lese-/Sperrsignal, Schritt 126. Das Sperrsignal wird nach Eingang in der Sende-/Empfangseinrichtung 21 dem Mikroprozessor 23 des Transponders 40 zugeleitet, welcher daraufhin die Sperrmittel 24 betätigt und die Verbindung von der Speichereinheit 25 zur Sende-/Empfangseinrichtung 21 unterbricht, Schritt 128. Die Unterbrechung ist nicht rücksetzbar und wirkt als dauernde Sperre. Ein erneutes Auslesen des Inhaltes der Speichereinheit 25 ist anschließend nicht mehr möglich. Das Durchführen der Sperrung quittiert der Mirkroprozessor 23 durch Rücksendung eines Quittungssignales. Sodann liest die Basisstation 10 die im flüchtigen Speicher 14 abgelegten Informationen aus der Speichereinheit 25 des zu ersetzenden Transponders 40 wieder aus und überträgt sie vollständig an den bereitstehenden neu zuzuordnenden Transponder 40, Schritt 130, 132. Jener übernimmt sie fest in seine Speichereinheit 25. Der neu zuzuordnende Transponder 40 besitzt daraufhin dieselbe Funktionalität wie der ersetzte Transponder 40.The sequence of a duplication process is described below of the flow chart, Figure 3, explained. The need to duplicate a transponder 40 is missing from it Functionality when used from a great distance obviously. The replacement of one obviously only transponder 40 connecting an empty battery 44 is then triggered manually by a user, for example by operating a switch, step 100. The base station 10 then checks to see if the user has duplicated one Transponders 40 is authorized. It is assumed here that the permission to duplicate a transponder 40 by the presence of a special, as the main operating element executed transponder 40, the so-called "redkeys" are proven. The base station 10 therefore checks Step 102 whether the redkey is within range of the Signal transmission path 30 is located. Isn't that If so, the duplication process is terminated, step 103. If the redkey is present, the base station 10 initiates the transponder 40 to be replaced by sending a corresponding one Control signals - step 104 - over the signal transmission link 30 to test his battery 44, step 106. The transponder 40 responds by sending one back Battery status message, step 108. Is the transponder 40 to duplicate thereafter, the base station 10 undergoes the replacing transponder 40 of a test of membership to base station 10, step 110. The membership check is preferably carried out by means of the "challenge-response" process. The base station 10 sends the checked one Transponder 40 a challenge signal in the form of a random number. By linking to that stored in the memory 15 cryptic key code 31 and the one stored in directory 18 Device code 27 of the tested transponder 40 forms a target response signal from the random number. In the same way, the Transponder 40 with access to the corresponding information in the memory unit 25 from the received challenge signal a response signal which it then sends to the base station 10 returns. The one compares it with the one before formed target response signal and closes if they match on the transponder 40 belonging to the base station 10. Is the affiliation of the transponder 40 to the base station After that, the base station 10 checks whether there is any in the range of the signal path 30 a reallocated, Transponder not yet "learned" on the base station 10 40 is located. To do this, it sets an open identification signal ab, step 112 that of in the range of the signal transmission path 30 to be re-assigned Transponders 40 is received. All present to be reassigned Transponders 40 respond to the receipt of an open one Identification signals by sending back a contact signal to base station 10, step 114. That leads thereupon a separation routine, step 116 if several newly assigned transponders 40 are present, all but one put into sleep mode, in which they do not participate in the subsequent communication participate more. After a single reallocate Transponder 40 is fixed, the base station 10 sets a signal by means of which the transponder 40 to be replaced is requested to be stored in the storage unit 25 Read out information and send it to the base station 10, Step 118. The transponder 40 to be replaced answers after receiving a readout request signal accordingly by returning those stored in the storage unit 25 Information to base unit 10, step 120. Those it takes over its transceiver 11 and stores them in volatile memory 14, step 122. Thereupon the base station 10 undergoes the transponder 40 again a membership test, step 124. You can like the membership check is carried out in accordance with step 110. is the result of the membership test again positive, sends the base station 10 to the transponder 40 to be replaced a read / lock signal, step 126. The lock signal is upon receipt in the transceiver 21, the microprocessor 23 of the transponder 40, which then the locking means 24 actuated and the connection from the Storage unit 25 to the transceiver 21 interrupts, Step 128. The interruption cannot be reset and acts as a permanent lock. A new reading of the content the storage unit 25 is then no longer possible. The microprocessor acknowledges the blocking 23 by sending back an acknowledgment signal. thereupon the base station 10 reads those in the volatile memory 14 stored information from the storage unit 25 of the replacing transponder 40 again and transmits them completely to the ready to be assigned transponder 40, step 130, 132. That one takes it in firmly its storage unit 25. The newly assigned transponder 40 then has the same functionality as the replaced one Transponder 40.

Das vorbeschriebene Verfahren läßt sich unter Beibehaltung seines grundlegenden Konzeptes vielfältig ausgestalten. So können sowohl die Verwendung eines redkeys als auch die Durchführung einer zusätzlichen Batterieprüfung entfallen. The procedure described above can be maintained design its basic concept in a variety of ways. So can use both a redkey and the An additional battery test is not necessary.

Auch kann vorgesehen sein, nur solche Informationen aus der Speichereinheit 25 auszulesen, welche im Speicher 15 der Basisstation 10 nicht entsprechend vorhanden sind. Beispielsweise ist die Übertragung von kryptischen Schlüsselcode 31 und Seriennummer 16 nicht zwingend erforderlich, da beide identisch im Speicher 15 der Basisstation 10 vorhanden sind. Denkbar ist ferner auch, den Inhalt der Speichereinheit 25 eines zu ersetzenden Transponders 40 unter Steuerung durch die Basisstation 10 direkt an einen neu zuzuordnenden Transponder 40 zu übertragen. Der flüchtige Speicher 14 in der Basisstation 10 ist dann nicht mehr erforderlich. Vielfältig gestaltbar sind ferner auch die Mittel 24 zum Sperren der Auslesefunktion.It can also be provided that only such information from the Read out memory unit 25, which in the memory 15 of the base station 10 are not available accordingly. For example is the transmission of cryptic key code 31 and serial number 16 not mandatory as both are identical in the memory 15 of the base station 10. It is also conceivable for the content of the storage unit 25 of a transponder 40 to be replaced under control by the base station 10 directly to a newly assigned transponder 40 to transfer. The volatile memory 14 in the Base station 10 is then no longer required. diverse the means 24 for locking the Reading function.
