    Method and device for extracting a value from an output unit into another unit
    The invention relates to a method for converting a value given in one output unit into a corresponding value in another unit. Such conversions are of increasing importance in practice, with the increase in the number of international contacts, foreign travel and the like. Moreover, in the future such calculations will in any case increase in number for several years now that many European countries have decided to abolish national currencies and to replace them with a supranational currency, the so-called Euro.
    The object of the invention is therefore to provide an unambiguous method for performing these calculations, which, moreover, can simply be implemented in a suitably programmed calculator. According to the invention, this is achieved by a calculation method in which the value in the output unit is first converted to a corresponding value in a standard unit, and then the calculated value in the standard unit is converted to the corresponding value in the other unit. By using a standard unit, for example the Euro, to which both the output unit and the other unit are related, the conversion method can be performed in the same way in all countries concerned and, if desired, implemented in calculators or computers.
    Preferred variants of the conversion method according to the invention form the subject of the subclaims 2 to 4.
    The invention further relates to a device for converting a value given in an output unit into a corresponding value in another unit, which is particularly, but not exclusively, suitable for carrying out the above-described method. According to the invention, such a conversion device is provided with means for inputting the value expressed in the output unit, memory means for storing a conversion factor of the output unit with respect to at least one other unit, calculating means connected to the input means and the memory means. converting the entered value into the corresponding value in the at least one other unit, and means connected to the calculating means for displaying the calculated value in the other unit, on the basis of the stored conversion factor. With such a device, which can be very compact, for instance in the format of a credit card, for example, during a stay abroad, amounts in the local currency can easily be converted into amounts in a known, in particular the home currency. In addition, with such an arrangement, amounts in the home national currency can easily be converted into an international standard currency such as the Euro, and vice versa.
    Preferred embodiments of the converter according to the invention are described in the subclaims 6 to 17.
    The invention is now elucidated on the basis of an example in which reference is made to the appended drawing, in which: fig. 1 shows a perspective view of the device according to the invention and a chip card to be used in combination therewith, fig. 2 schematically shows the construction of the device of FIG. 1 and FIG. 3 illustrates an alternative embodiment of the device capable of communicating directly with an ATM.
    A conversion device 1 comprises a housing 12 in which the electronics 13 is accommodated for the calculator. of values from one unit to another. This electronics 13 comprises a processing unit 15 and a memory 16 connected thereto. The device 1 further comprises input means 2 connected to this electronics 13, formed by a number of digit keys 5, operation keys 6, operating keys 9, 10 and 11 for moving in a menu, the so-called 'scrolling', and a key 8 for setting a conversion factor relative to a standard unit. The device 1 further comprises means 14 for displaying the results of the calculations. In the example shown, the display means 14 are arranged to simultaneously display a given value in one unit, referred to as the output unit, and the value calculated therefrom in the other unit. For this purpose, the display means 14 are formed by two display screens placed next to each other, for example LCD screens 3, 4. Instead of two screens, the use of a single screen with, for example, two frames or display surfaces would of course also be possible.
    When using the device 1, the output unit and the other unit can be selected in tables appearing in windows 3, 4 using the 1 scroll keys 9 and 10. Subsequently, values can be entered with the aid of the number keys 5, on which arithmetic operations are performed with the aid of the processing keys 6. The results of these operations are simultaneously displayed in windows 3, 4 in the output and other units. Use the button 8 to set the conversion factors of the different units.
    The device 1 is hereby switched to an update state, in which the current value of each unit selected with the scroll keys 9, 10 relative to the standard unit, in practice the Euro, is entered using the number keys and stored in the memory. 16 cp can be beaten. With the help of the 'scroll' key 11 the active calculation function per screen 3, 4 can still be changed.
    The 1 scroll keys 9, 10 could also be used, for example, when the results of a calculation in both units are on screens 3, 4, to display other values. To this end, the device 1 should be programmed in such a way that when one of the scroll keys 9, 10 is pressed, a table would be called up from the memory 16, in which corresponding values are recorded in the two respective units, the data currently being stored. the value shown in the screens 3, 4 in both units should be taken as a starting point. By pressing the up or down pointing part of one of the keys 9, 10, ascending or decreasing values in the two selected units would then appear in screens 3, 4, based on the displayed value. For example, with an entered value in one unit it would be easy to look up a corresponding value in the other unit.
    Incidentally, the updating of the conversion factor (s) in the memory 16 could also be performed automatically. To this end, the device 1 could be provided with receiving means 17, which should be connected to the electronics 13. The actual value of the conversion factors could then, for example, be periodically sent from a certain central point to each converter 1 which is within the transmission range, in the same way that certain timepieces are set.
    The updating could also take place by providing the device 1 with receiving means 17 which are suitable for wirelessly reading out the contents of an integrated circuit 18, which is for instance arranged on a chip card 19, such as the so-called "Chipknip". By then holding the chip card 19 in the vicinity of the device 1, the actual values of the conversion factors stored in the chip 18 on the card 19 could then be read simply in the memory 16. To this end, the device 1 could be provided with a recording space 22, for instance a slot, into which the chip card 19 could be inserted to be read. The conversion factors could then be loaded in a manner already known per se into the chip 18 on the card 19 in a central charging station, such as an ATM 20. Incidentally, if the device 1 is sufficiently small and thin, for example in credit card format could also be inserted directly into an ATM 20 to take over the updated conversion factors (Fig. 3).
    In addition to receiving means 17, the device 1 could also be provided with transmitting means 21 integrated therewith. As a result, not only current values of conversion factors could be transferred from a central office into the memory 16, but also data from the memory 16 of the device 1 can be executed. Like the receiving means 17, these transmitting means 21 could be arranged for communication with an IC memory 18 on a chip card 19, or for direct communication with, for example, an ATM 20.
    Incidentally, in this way not only exchange factors and results of calculations performed by the device 1 could be exchanged, but other data could also be passed on from an ATM 20 to the device 1 and vice versa. For example, general communications from a bank could be passed on to all its relations in this way, but also targeted messages intended only for a specific client could be read. The bank could not only distribute its own messages in this way, but could also send third-party notifications, such as advertisements. In addition, a user could send COK messages in this way, and possibly carry out money transactions, such as, for example, depositing part of the balance present on the chip card or own account or making a payment by direct deposit. on the creditor's account.
    Incidentally, the manner of communication via the ATM 20 described above need not be limited to converters of the type described above, but could also be used in combination with a simple balance reader for a chip card.
