`(54) Card reader device and method for triggering
`an event in such a device
`
`(57) In the case of a telephone device that has a card
`reader for prepaid cards, each prepaid card is checked
`if its card value has reached zero (Step 22). During this
`process, it is checked whether the card belongs to a
`specific card group (Step 26). If yes, a serial number of
`the card is compared with a list stored in the memory
`of the device (Step 28), and it is determined, in this
`manner, whether a specific event is supposed to be
`triggered. This event can be, for example, display of a
`lottery prize or some other incentive.

`
`Specification
`

`

`
`The invention relates to a card reader device and
`to a method for triggering an event in such a device, in
`accordance with the preambles of the independent
`claims.
`Card reader devices of this type are used, for
`example, in telephone devices, so as to read prepaid
`cards and to reduce their value. In this process, the
`value of the card is reduced in accordance with the
`fees that are incurred, until the value of the card is
`reduced to zero. Normally, cards with a zero monetary
`value only have value for collectors, unless the cards
`can be recharged.
`Against this background, the task arises of
`configuring the reader devices and the cards in such a
`manner that new applications open up and thereby
`customer acceptance is increased.
`This task is accomplished by the object of the
`independent claims.
`According to the invention, it is therefore checked
`whether the value of the card lies in a specific range or
`has reached a target value, and, at the same time,
`whether it belongs to a specific subgroup of all possible
`cards. If these two conditions are met, then a specific
`event is triggered. This event can be, for example, a
`surprise for the user, particularly the information
`whether or not the user has achieved a lottery prize.
`Preferably a serial number memory is placed in
`the card, which can be checked by the reader device.
`In this connection, the event is only triggered if it is
`determined, on the basis of the serial number, whether
`the card belongs to the subgroup. For this purpose, the
`final digits of the serial number can be compared, for
`example, with a table that is stored in the reader
`device. In this regard the serial number is a number
`that is different for each individual card, or that is at
`least used only by a small number of cards at the same
`time.
`In addition to a serial number, a group memory
`can be provided in the memory of the card, which
`states whether the card is even authorized to trigger
`the event. Such a group memory requires only a single
`bit or a few bits, and allows reliable checking of the
`card authorization even if it cannot be determined on
`the basis of the serial number alone whether the card
`can trigger the event. In particular, it is not necessary
`that all of the potentially authorized cards possess
`serial numbers having specific characteristics.
`Preferably the value-checking and selection step
`is carried out independently of whether the value
`memory has previously been changed in the same
`reader device. This has the advantages that not all the
`reader devices need to be able to carry out the
`aforementioned steps. For example, if the value of the
`card is reduced in a device that cannot trigger the
`event, then the user can check it later in a device that
`is set up for carrying out the required steps.
`Further preferred embodiments and applications of
`the invention are evident from the dependent claims
`and from the following description, using the figures.

`triggering the event.
`First of all, one of the possible embodiments of the
`invention will be explained using the figures. Further
`possible embodiment variants will be discussed at the
`end of the description.
`The embodiment shown in the figures is an
`application in the sector of telephone devices. In
`particular in the public sector, such devices are often
`equipped with a card reader. For operating the device,
`a prepaid card must be inserted into this reader. The
`prepaid card possesses a memory that can be optical
`or electronic, for example, and indicates the current
`card value. During a call, the fees incurred are
`charged, and the value of the card is reduced.
`Common cards of this type are described, for example,
`in the ISO Standard 7816 and the ETSI Standard PrEN
`726. Cards of this type are used as “postcards” or
`credit cards, for example.
`Such a card is shown in Figure 1. It possesses
`contacts for the card reader, which are connected with
`a memory chip in the interior of the card. As a rule, the
`card has an inscription 2; in the present case, it also
`has an imprinted serial number 3.
`Figure 2 shows the basic structure of a telephone
`device that has a card reader 4. The device comprises
`a controller 5, which accesses data in a memory 6. To
`operate the device, a keyboard and a display 7 are
`provided. The controller 5 controls the function of the
`telephone part 8, which comprises the elements that
`give the device its actual telephone functions, such as
`a handset and suitable interface circuits for connecting
`to the telephone network 9. Furthermore the telephone
`part also comprises a modem, by means of which the
`controller 5 can exchange binary data by way of the
`telephone network 9.
`Before discussing the method of functioning of the
`device and of the card from a technical point of view,
`the desired capabilities from the user’s point of view
`will be briefly discussed below.
`In the present case, it is supposed to be possible
`for the user to acquire two different types of cards. The
`first type involves conventional cards that possess a
`specific initial value. The card value is reduced in a
`known manner when telephoning, until the card value
`is reduced to zero. After that time, the card at most has
`value for a collector.
`The second type of cards involves lottery ticket
`cards. These cards are also provided with a specific
`value at the beginning, which value is reduced in
`accordance with the charges incurred while
`telephoning. However, as soon as the value of the card
`has been reduced to zero, it acts as a lottery ticket.

`
`When the telephone device recognizes a lottery ticket
`card having a value reduced to zero, it checks whether
`this card is authorized for a prize. If yes, the user is
`informed of this in a suitable manner.
`The technical implementation of this concept is
`evident from Figures 3 to 6.
`In Figure 3, the memory of the card is shown in a
`simplified manner. This involves a non-volatile memory
`that is divided up into two regions 10 and 11. Values
`that can no longer be changed after the card is sold
`are contained in the region 10, while the data in the
`region 11 can still be changed, at least to a restricted
`extent, by the reader device of the telephone.
`In the protected region 10, a serial number
`memory 12 is provided. This memory contains a serial
`number that is different for each card, or one that at
`least only a few cards possess. These numbers can
`involve digits with which the card manufacturer
`numbers the cards of a shipment in ascending order.
`As shown in Figure 1, the serial number can
`additionally be imprinted on the outside of the card.
`Furthermore, a group memory 13 is provided in
`the protected region. This memory indicates whether a
`card is a lottery ticket card or a conventional card. This
`information is particularly important if it cannot be
`determined on the basis of the serial number alone
`whether or not a card is a lottery ticket card. The group
`memory requires only a few bits.
`There is a value memory 14 in the unprotected (or
`only partially protected) region 11 of the memory of the
`card, the value of which memory is reduced by the
`reader device in a known secured manner, in
`accordance with the charges incurred.
`Figure 4 shows a detail of the memory 6 of the
`reader device. In this region, there is a list of the serial
`numbers that are authorized for a prize. In a first part
`16 of the table, for example, those serial numbers that
`represent a prize of CHF 100.00 are recorded. In the
`case of the present example, these serial numbers are
`characterized in that their last three digits are 235, 421
`or 991. There is a corresponding list of final digits for
`serial numbers that are authorized to receive a prize of
`CHF 1,000.00 in the part 17 of the table. In the last part
`18, there is a list of the serial numbers authorized to
`receive one of the top prizes.
`Of course the table according to Figure 4 shows
`only one of the many possibilities as to how the serial
`number can be evaluated and the corresponding
`information can be stored.
`Preferably the data in the table according to Figure
`4 are present in encrypted form, so as to reduce the
`risk of unauthorized reading, for example in the case of
`a stolen card reader device.
`When a card is inserted into the reader device, or
`when the value of the same card is reduced to zero
`while telephoning, the steps that are shown in
`summary in Figures 5 and 6 are carried out.
`In the first step 20, the group memory 13 of the
`card is read. If the card is not a lottery card on the
`basis of this value (Step 22), checking is stopped at
`Point C and the card is used as a normal prepaid card.

`

`
`55
`
`In Step 24, the serial number from the
`corresponding serial number memory 12 is compared
`with those contained in the table according to Figure 4.
`If the number does not meet the prize criteria (Step
`26), checking is stopped at Point C.
`In Step 28, the card value in the value memory 14
`is checked after every debiting, if necessary
`repeatedly. If the card value has not yet reached 0
`(Step 22), checking is stopped at Point C. Otherwise
`an event is triggered at Point B.
`In this regard, the sequence shown in Figure 6, for
`example, can be involved, in which the user is
`informed of the corresponding prize on the display 7
`(Step 32). However, it is also conceivable that the
`device then automatically produces a telephone
`connection with the central office of the lottery operator
`(Step 34), with the winner being informed how he can
`get his prize, for example by sending his card to the
`lottery operator or exchanging it for the prize at a
`designated location. Preferably, a different event is
`triggered depending on the prize to which the user is
`entitled, for example in that a text adapted to the prize
`is displayed on the display 7.
`The table according to Figure 4, i.e. the
`corresponding evaluation algorithm, can be
`permanently stored in the device. However, this has
`the disadvantage that fraudsters could determine, by
`means of albeit complicated investigations, which of
`the cards is entitled to a prize.
`In order to reduce this problem, the numbers
`authorized to receive a prize can be changed
`periodically. Preferably, for this purpose the value of
`the table according to Figure 4, i.e. the corresponding
`evaluation algorithm, could be updated accordingly by
`means of reprogramming the terminal.
`It is also conceivable that a decision as to whether
`a card is entitled to a prize is made not only on the
`basis of the final digits of the serial number. The risk of
`decryption is reduced by means of the use of a
`complicated algorithm, and this makes it more difficult
`for a fraudster to recognize prize cards.
`Fundamentally, the serial number can be transformed
`mathematically by means of any suitable algorithm,
`whereupon the transformed value is then checked with
`regard to specific criteria. For example, a hash value,
`for example a horizontal checksum, can be generated
`on the basis of the serial number, by means of a
`suitable algorithm, with a prize being indicated if the
`hash value has a predetermined size.
`However, the entitlement of a card to a prize does
`not necessarily need to be encrypted in the card
`number. It is also conceivable that corresponding
`information is explicitly written into the protected part
`10 of the card memory. This information can comprise,
`for example, a telephone number that is called in the
`event of a prize of a specific amount or displayed to the
`user.
`It is also conceivable that instead of following
`Steps 28 and 30, the reader device decides, on the
`basis of a random algorithm, whether the card is
`supposed to be entitled to a prize. The result is written
`into the card in an unchangeable manner, and the user
`

`
`

`

`

`
`is informed of it. However, in this case very high prize
`amounts should not be used, on the basis of statistical
`considerations.
`As has already been mentioned, the card can be a
`prepaid card that can only be reduced in value to zero
`once. However, a chip card that is rechargeable can
`also be used. In this case, the user can say, for
`example when recharging his card, whether he wants
`to pay an additional fee that entitles him to participate
`in the lottery. If yes, the group memory 13 of the card is
`set accordingly, and the card becomes a lottery ticket
`card.
`The invention is not just suitable for use in
`telephone devices. It is also conceivable to equip other
`devices with a corresponding function, for example
`self-service gas station pumps, beverage vending
`machines, etc.
`Instead of displaying a lottery prize, the lottery
`ticket card can also trigger a different event, for
`example:
`
`- free-of-charge distribution of an article (for
`example in the case of a vending machine),
`- a one-time credit to the card,
`- issuance of a lottery number between 1 and
`13, with the user only becoming entitled to a
`prize if he has received a total of three of the
`same lottery numbers from different cards,
`- issuance of an advertising text that
`encourages him to purchase a new card from
`the same vendor and offers a rebate,
`- etc.
`
`In that the corresponding events are only triggered
`when the value of the card has dropped to a
`predetermined level (for example 0) or a certain value
`range, the risk of abuse is reduced, and furthermore an
`incentive is offered for using up the card as soon as
`possible.

`
`Kartenlesegerät und Verfahren zur Auslösung eines Ereignisses in einem solchen Gerät
`
`Bei einem Fernsprechgerät, welches einen
`(57)
`Kartenleser für Wertkarten aufweist, wird jede Wert-
`karte geprüft, deren Kartenwert Null erreicht hat (Schritt
`22). Dabei wird untersucht, ob die Karte einer gewissen
`Kartengruppe angehört (Schritt 26). Falls ja, so wird
`eine Seriennummer der Karte mit einer im Gerät abge-
`speicherten Liste verglichen (Schritt 28) und auf diese
`Weise festgestellt, ob ein gewisses Ereignis ausgelöst
`werden soll. Bei diesem Ereignis kann es sich zum Bei-
`spiel um die Anzeige eines Lottogewinns oder einen
`anderen Anreiz handeln.

`
`kann sie der Benutzer danach in einem Gerät prüfen,
`welches zur Ausführung der dazu notwendigen Schritte
`eingerichtet ist.
`Weitere bevorzugte Ausführungen und Anwendun-
`gen der Erfindung ergeben sich aus den abhängigen
`Ansprüchen sowie aus der nun folgenden Beschreibung
`anhand der Figuren. Dabei zeigen:
`
`Figur 1 eine Karte zur Verwendung im erfindungs-
`gemässen Verfahren,
`Figur 2 ein vereinfachtes Blockschaltbild eines Kar-
`tenlesegeräts in Form eines Fernsprechgeräts,
`Figur 3 einen Auszug aus dem Speicher der Karte,
`Figur 4 einen Auszug aus dem Speicher des Kar-
`tenlesegeräts,
`Figur 5 den Ablauf bei der Prüfung einer Karte und
`Figur 6 ein mögliches Vorgehen beim Auslösen des
`Ereignisses.
`
`Zuerst soll anhand der Figuren eine der möglichen
`Ausführungen der Erfindung erörtert werden. Auf wei-
`tere der möglichen Ausführungsvarianten wird am
`Schluss der Beschreibung eingegangen.
`Bei der in den Figuren dargestellten Ausführung
`handelt es sich um eine Anwendung im Bereich der
`Insbesondere
`im
`öffentlichen
`Fernsprechgeräte.
`Bereich sind solche Geräte oftmals mit einem Kartenle-
`ser ausgestattet. Zum Betrieb des Geräts muss eine
`Wertkarte in diesen Leser eingeschoben werden. Die
`Wertkarte besitzt einen Speicher, der zum Beispiel
`optisch oder elektronisch sein kann, welcher den
`momentanen Kartenwert wiedergibt. Während eines
`Gesprächs werden die anfallenden Gebühren der Karte
`belastet und deren Wert wird reduziert. Gängige Karten
`dieser Art sind zum Beispiel in der ISO-Norm 7816 und
`im ETSI-Standard PrEN 726 beschrieben. Karten die-
`ser Art werden z.B. als "Postcards" oder Kreditkarten
`verwendet.
`In Figur 1 wird eine solche Karte dargestellt. Sie
`besitzt Kontakte 1 für den Kartenleser, die mit einem
`Speicherchip im Innern der Karte verbunden sind. In
`der Regel trägt sie eine Aufschrift 2, im vorliegenden
`Beispiel auch eine aufgedruckte Seriennummer 3.
`Figur 2 zeigt den Grundaufbau eines Fernsprech-
`geräts mit Kartenleser 4. Das Gerät umfasst eine
`Steuerung 5, welche auf Daten in einem Speicher 6
`zugreift. Zur Bedienung des Geräts ist eine Tastatur und
`Anzeige 7 vorgesehen. Die Steuerung 5 steuert die
`Funktion des Telefonteils 8, welcher die Elemente
`umfasst, die dem Gerät die eigentlichen Telefonfunktio-
`nen verleihen, wie z.B. einen Hörer und geeignete Inter-
`faceschaltungen zum Fernsprechnetz 9. Ferner
`umfasst der Telefonteil 8 auch ein Modem, mittels dem
`die Steuerung 5 binäre Daten über das Fernsprechnetz
`9 austauschen kann.
`Bevor aus technischer Sicht auf die Funktionsweise
`des Geräts und der Karte eingegangen wird, werden im
`folgenden kurz die gewünschten Fähigkeiten aus Sicht
`
`s
`
`Die Erfindung betrifft ein Kartenlesegerät und ein
`Verfahren zum Auslösen eines Ereignisses in einem
`solchen Gerät gemäss den Oberbegriffen der unabhän-
`gigen Ansprüche.
`Kartenlesegeräte dieser Art werden zum Beispiel in
`Fernsprechgeräten eingesetzt, um Wertkarten zu lesen
`und zu entwerten. Dabei wird der Wert der Karte
`gemäss den anfallenden Gebühren verringert, bis die 10
`Karte entwertet ist. Entwertete Karten besitzen norma-
`lerweise nur noch für Sammler einen Wert, es sei denn,
`die Karten können neu aufgeladen werden.
`Es stellt sich auf diesem Hintergrund die Aufgabe,
`die Lesegeräte und Karten so auszugestalten, dass 15
`sich neue Anwendungen eröffnen und somit die Kun-
`denakzeptanz erhöht wird.
`Diese Aufgabe wird vom Gegenstand der unabhän-
`gigen Ansprüche erfüllt.
`Erfindungsgemäss wird also geprüft, ob der Wert 20
`der Karte in einem bestimmten Bereich liegt bzw. einen
`Zielwert erreicht hat, und ob sie gleichzeitig einer
`bestimmten Teilgruppe aller möglichen Karten zuge-
`hört. Wenn diese beiden Bedingungen erfüllt sind, so
`wird ein bestimmtes Ereignis ausgelöst. Bei diesem 25
`Ereignis kann es sich zum Beispiel um eine Überra-
`schung für den Benutzer handeln, insbesondere um die
`Angabe, ob der Benutzer einen Lotteriegewinn gemacht
`hat oder nicht.
`Vorzugsweise wird in der Karte ein Seriennum- 30
`mernspeicher angeordnet, welcher vom Lesegerät
`geprüft wird. Das Ereignis wird dabei nur dann ausge-
`löst, wenn aufgrund der Seriennummer festgestellt wird,
`ob die Karte der Teilgruppe angehört. Hierzu können
`zum Beispiel die Endziffern der Seriennummer mit einer 35
`Tabelle verglichen werden, die im Lesegerät abgespei-
`chert ist. Die Seriennummer ist dabei eine Zahl, die für
`jede einzelne Karte unterschiedlich ist, oder die zumin-
`dest nur von einer kleinen Zahl von Karten gleichzeitig
`verwendet wird.
`Zusätzlich zu einer Seriennummer kann im Spei-
`cher der Karte ein Gruppenspeicher vorgesehen sein,
`der aussagt, ob die Karte zur Auslösung des Ereignis-
`ses überhaupt berechtigt ist. Ein solcher Gruppenspei-
`cher benötigt nur ein einziges oder einige wenige Bits 45
`und erlaubt eine sichere Prüfung der Kartenberechti-
`gung, selbst wenn aufgrund der Seriennummer alleine
`nicht feststellbar ist, ob die Karte das Ereignis auslösen
`kann. Insbesondere ist es nicht notwendig, dass alle der
`potentiell berechtigten Karten Seriennummern mit
`bestimmten Charakteristika besitzen.
`Vorzugsweise wird der Wertprüfungs- und Aus-
`wahlschritt unabhängig davon ausgeführt, ob der Wert-
`speicher zuvor im gleichen Lesegerät verändert worden
`ist. Dies hat den Vorteil, dass
