In other words, the first track information is provided by a first track (152), second track information is provided by the second track (154), third track information to be provided by the third track (156) can.

Card reader 20 is a magnetic field signal recognized by the body 21 and the main body is installed in the 21 the smart card 10 the head unit 200 which can detect the magnetic field generated from the head unit 200 processing may include a reader control section 22 to perform a predetermined process.

The head unit 200 can be installed toward the inner side of the slot. The head unit 200 is provided to recognize the magnetic field of the smart card 10 that may be exposed to the inside space of the slot, through the shielded slot or water, but which when in a predetermined member.

Similarly, the head unit 200 may be provided with three heads (210, 220, 230) to read the three track information. Claim to the first head 210 detects the magnetic field generated from the first track and to detect one magnetic field generated from 152, a second head 220 is a second track 154, and the third head ( 230) may sense the magnetic field generated in the third track (156). Of course, the head unit 200 may detect the first track information, the second information track, and the third track information provided by the magnetic card when the conventional magnetic card used.

The first head 210 and second head gap (d2) between the distance (d1) and the second head 220 and third head 230 between 220 may be pre-determined according to the standard, the distance between the first track 152 and second track 154, the interval and the second track 154 and the third track (156) between the can correspond thereto.

In addition, the center of the head unit 200 includes a smart card 10, the card reader 20, the respective tracks (152, 154, 156) is substantially each head (210, 220, 230) centered at the time to be read on the can be arranged to pass.

In this embodiment, as the case has been described in that example, three heads in the head unit 200 is provided as an example can be varied are the number of the head. For example, a card reader, the head unit 200 to be mounted on a specific track the information is unnecessary if, this card reader 20 in accordance with the intended use of the 20 may include only one or two heads.

On the other hand, one side of the magnetic-field generating unit 150, specifically, the group is the head provided in the card reader 20, the head unit 200 side of the direction in which the entry in that set detection head that can detect (210, 220, 230) It may be provided with a portion (160). Head detection unit 160 may be provided not exposed to the outside of the facade the smart card 10, may be placed side by side with the magnetic-field generating unit 150 in the portion that corresponds to a conventional magnetic strip.

In this embodiment, there is a head (210, 220, 230) according to the embodiment has been described as a detection target of the head detection unit 160, a head (210, 220, 230) of the card reader 20 is attached It may be configured to recognize that the mounting part, or separately provided identifier. The head detection unit 160 not to detect the counterpart of the card reader 20, and may be by detecting a movement of the smart card 10 for detecting that the smart card 10 scratching. In short, the head detection unit 160 includes a smart card 10 that will be detected by scratching the moment the card reader 20, a control unit 110-magnetic-field generating unit 150 in response to the detected result of the head detector 160 on the current supply.

Smart card users by detecting the presence or absence of scratching the smart card 10 into the card reader 20, the head detection unit 160 is the first to face the head unit 200, a head (210, 220, 230) and it delivers a signal to the control unit 110 of (10) (S100).

The control unit 110 includes a head detecting unit 160, the head (210, 220, 230) for receiving signal has detected, each track by supplying a current to the magnetic-field generating unit 150 (152, 154, 156) from It generates a magnetic field in order (S200) through.

Specifically, the control unit 110 may generate a magnetic field with a first track 152 and second track 154, the third track (156) sequence. At this time, the control unit 110 first and then after a magnetic field is generated by the track 152 is completed to generate a magnetic field on the second track 154, the magnetic field is generated through the second track (154) has completed the third track ( 156) can generate a magnetic field through. Thereby, the magnetic field signals generated from the respective tracks (152, 154, 156) may not overlap each other.

Here, the magnetic field signals generated by the respective tracks (152, 154, 156) is readable magnetic field signals from the reader control section 22, specifically, the magnetic field generated in accordance with the predetermined interval as shown in Figure 5 It can be a signal. To this end, the control unit 110 of the smart card 10 is capable of supplying intermittent current to the magnetic field controller 150.

With reference to Figure 5 and looking in more detail, the control unit 110 first in time intervals, the number set up in the first track 152 and can supply current to from t1 t2, and therefore, the magnetic field is generated, or is not generated situation that is generated continuously. Here, the size (m) of the magnetic field generated is at least a first head 210 can be effectively sensing a change in the magnetic field may be set to a size that in the, in the present embodiment, each track (152, 154, 156) since the track information is sequentially generated from the second head 220 or the third but may be set in the head 230 to which can be effectively sensing a change in magnetic field magnitude.

At this time, the group as a set time interval, the number of times the card information of the user and the selected card, a is stored in the memory 110 can be loaded according to the user selection of the cards. That is, the magnetic card reader 20 is generated, where may be recognized as a binary code composed of 0 and 1. For example, unit time (1 bit period), when there is no change in the magnetic field creating the card reader 20 recognizes this to zero, when there is a change in the magnetic field creating a card reader 20, while to recognize it as a first and, whether or not lapse of each unit time can be divided by the magnetic field generated. Thus, as in the magnetic field signals generated from the first track (152) is subject to the card selected by the user, the smart card 10 is to dynamically generate the magnetic field signals.

Control unit 110 when the magnetic field generated by the first track 152 to t2 is completed, it is possible to wait until t3. In this case, the waiting time (t3-t2) may be set to a value greater than zero, it can be properly adjusted depending on the overall magnetic field generation time is set.

t3 after the control unit 110 of the magnetic field through the second track 154, the above method results in up to t4. In this case the magnetic field signal generated may be a user that has been stored in the memory 120, the card information for the selected card may be Shin Hoil corresponding to the second information track.

Control unit 110 when the magnetic field generated by the second track (154) to t4 is completed, it is possible to wait up to t5, similarly the standby time (t5-t4) can be set to a value greater than zero. Then, the control unit 110 can supply a third current to the track 156, from t5 to t6 generate a magnetic field signal corresponding to the information track 3.

Here, the strength of the magnetic field generated in the second track 154 and the third track (156) is enabled in, but may be equal to m, it is not limited to each of the second head 220, and the third head 230 but it may occur when a large magnetic field than the size that can be recognized.

On the other hand, in this embodiment, the control unit 110, but an example demonstrated that for generating a magnetic field by supplying a first track 152 and second track 154, the current to the third track (156) in order, each track order in which the current is supplied to the (152, 154, 156) may be may be changed, this current supply order is set group.

In this embodiment, the three tracks (152, 154, 156) a track all been described as an example that the current is supplied, in some cases the may not be used. In this case, the control unit 110 can supply the three tracks (152, 154, 156) of the electric current sequentially to two or more tracks.

Further, in the present embodiment, the current supply to the respective tracks (152, 154, 156) are, but after the supply of the current to any one of the track is completed described example that goes in the following of the track for example, set such that some sections are superposed It may be. For example, the third track, the first track 152 with the, or the current supply is started, the current supply to the second track (154) before the end, before the end of the current supply to the second track (154) 156 the current supply may be started with.

Card reader 20 may proceed after having detected through the head unit 200, the magnetic field signals generated as described above, and the reader control section 22 reads out this analysis in a predetermined binary code, the subsequent processing thereof. Card reader 20, even if the magnetic field in each of the tracks (152, 154, 156) occurs sequentially as in the present embodiment, if the magnetic field information entered in the effective time preset can be effectively read out the respective track information is. At this time, the time (t6) that the controller 110 is to supply all the current to each of the tracks to complete the magnetic field generated is apparent also be less than than the predetermined expiration time.

According to the smart card 10 and the control method thereof according to an embodiment of the present invention as described above, since the magnetic field signals generated from the respective tracks (152, 154, 146) to generate a track information so as not to overlap each other card reader 20. in can be clearly it is possible to recognize the separation of the respective track information, exactly in the smart card 10 the card recognition rate is improved and at the same time, the card reader 20 to pass the card information.

In particular, any one track (152, 154, 156) in time to produce a magnetic field, corresponding to the head (210, 220, 230) are not adjacent may generate a size field of a level that could be recognized by the other head is. In this case, corresponding to the head is able to more reliably recognize the track information, recognized by the other head information is determined to be noise, not a track information of a corresponding specification in the reader, the control section 22 accurately card without problems a reader (20), the track information can be transmitted.

In addition, since the respective tracks and additional mechanical means for preventing affecting tracks the magnetic field signal close generated in the (152, 154, 156) to configure the smart card 10 without (the shielding film and the like), Flat it is possible to significantly improve the space utilization problem of the smart card 10 to be implemented in size.

Hereinafter will be described with respect to FIG smart card for generating a dynamic magnetic field in a sequence according to another embodiment of the present invention refer to 7. However, the other embodiments because there are differences in the structure-field generating portion as compared with the embodiment of Figure 4, the difference mainly described, and the distance in the embodiment described with reference numerals with respect to the same components.

7 is a view schematically showing a magnetic field generating unit when the state of the smart card for generating a dynamic magnetic field in a sequence in accordance with another embodiment of the invention is read in a card reader, the card reader of the head and the smart card.

7, the magnetic field generation section (150a) of the smart card (10a) in accordance with another embodiment of the present invention may be of a first track (152a) and third track (156a). The first track (152a) is disposed at a position corresponding to the track 1 of the conventional magnetic cards such as in the above embodiment, it is disposed in a location that corresponds to a first head 210 of the card reader (20) . In addition, the third track (156a) is in a location that is disposed at a position corresponding to the track 3 of the conventional magnetic cards, can correspond to the third head 230 of the card reader 20, as shown in the above embodiment; It is arranged. That is, the smart card according to the present embodiment (10a) may have the form of a second track (154) is omitted in the above embodiments. That is, between the first track (152a) and third track (156a), there may not be provided with a track.

In this embodiment, the first track (152a) can generate both the first track information and the second information tracks. To this end, the control unit 110 first track (152a) is also heard example 5, the first current for generating the magnetic field signals from the current and t3 for generating a magnetic field signal from t1 to t2 to t4 first track It can be provided to both the 152. At this time, the magnitude of the current provided by the control unit 110, that is, the magnitude of the magnetic field generated from the first track (152a) may be set large enough to recognize the change of the magnetic field at the second head 220, in the above embodiment it may be set to a value larger than the m value. In this case, the magnitude of the magnetic field generated by the first track (152a) may be cells than the size of the magnetic field generated in the third track (156a).

Specifically, in the case according to the ISO 4909 standard, first track information, a start signal (SS, Start Sentinel), the format code (Code Format), the main account (PAN, Primary Account No.), the field separator (FS, Field Seperator) can be configured with a name (name), field separator, additional data (additional data), free data (Discretionary data), the end signal (ES, end Sentinel), longitudinal redundancy check character (LRC, longitudinal redundancy Check character). The second track information may be of a start signal, a main account, the field separator, the additional data, a free data, the end signal, the longitudinal redundancy check character. And the third track information can be configured as a start signal, format code, main account, the field separator, use and security of data (Use and Security Data), additional data end signal, vertical redundancy check character.

Here, the first track information for the corresponding% and a start signal and end signal, and the second information track and the third track information to the start signal and end signal, uses the? Thus, less is the risk of confusion, the first track information and the second track information or the first track information and the third track information from the card reader (20), second track information and the third track information is greater the risk of confusion.

Therefore, it is possible to provide the first track information and the called track information reliably and securely, even if provided with using the two-track data of the first track (152a), as in this embodiment, the card reader 20 .

In particular, the smart card 10 according to this embodiment, but use of the first track (152a), so the first track and the second information sequence generate the track information, the above risk of confusion may be further reduced.

Furthermore, the even if the sensor magnetic field generated from the first track (152a), third track (156a) and are so spaced apart, the potential to affect the three tracks (152a) are low, so it is possible to provide a track information reliably .

Further, by omitting the second track, it is possible to more simplify the configuration of the smart card 10, it is possible to improve the productivity.

On the other hand, in the embodiment, but it described with reference to the first track (152a) provides the first track information and the second track information, and the third track (156a) is provided for the third track information, for example, the first track ( 152a) this may be the only one providing the track information, and the third track (156a) is provided a second information track and the third track information. That is, any one of the first track (152a) and a third track (156a) that can provide the two information tracks.

Hereinafter will be described with reference to FIG. 8 with respect to the smart card for generating a dynamic magnetic field in a sequence according to an embodiment of the present invention. However, the further embodiment will explain, because the difference is a difference in the position of the first track as compared with the embodiment of Figure 7, and mainly incorporated in the embodiment described with reference numerals with respect to the same components.

8 is a view schematically showing a magnetic field generating portion of the present figure again when the smart card for generating a dynamic magnetic field in a sequence in accordance with another embodiment of the invention is read in a card reader, the card reader of the head and the smart card.

8, the magnetic field generation section (150b) of the smart card (10b) according to another embodiment of the present invention may be of a first track (152b) and third track (156b). Here, the first track (152b) may be arranged at a position between the track 1 and track 2 of the conventional magnetic card. In other words, the first track (152b) may be arranged in a region between the first head 210 and second head 220 of the card reader (20).

In this case, the smart card (10b) comprises a first track (152b), there may generate a magnetic field signals both recognizable by the first head 210 and second head 220 without providing the large-size current. Thus, it is possible to reduce the power consumption of the smart card (10b), can increase the amount of time that you can use a smart card (10b) with a single charge.

According to a further embodiment of the present invention, as needed, the user can request the use of the smart card 10 to a third party. At this time, the user after switching the smart card 10 to the use mode can be handed to a third party. Use mode, the smart card 10 is pre-set when the conditions are met, as meaning a mode of operation does not provide the card information to the card reader, For example the smart card 10 after the switch to the use mode 1 once used, ie after the one-time provision of information to the card reader it may not provide information to the card reader anymore. Alternatively, the smart card 10 to 30 seconds after the switch to the use mode can be provided with information only within a card reader, and thereafter may not be able to provide information to the card reader.

Then, the third party smart card 10 a can be used as a way to scratch or inserted into the card reader during a limited connection conditions, this time, the control unit 110 exposes the terminal (140 to any one of the card information selected by the user ) can be provided on how the card reader for transmitting the contact into the card reader, or a magnetic field generated by the magnetic-field generating unit 150 through.

Thereafter, if, using the constraint is satisfied, or a third party without the user having to take other action to separate the smart card 10 may be automatically switched to a state that can not be provided in the card information.

When use is completed, the user can OFF the power to the smart card 10 by using the power button 182.

Specifically, the user may select the card information of a particular card of the card information of the plurality of cards which are stored in the smart card 10 via the user interface unit 180. In addition, it is possible to switch the smart card 10 to the use mode. Here, the use restriction mode, when the smart card 10 the predetermined condition is satisfied, means a mode of operation does not provide the card information to the card reader. Further, memory 130 may store the use restriction information for restricting the use of the smart card 10. Specifically, the use restriction information is a condition for switching the smart card 10 by using the limited conditions that can not be used from the available enabled to use, can comprise a number of possible or available information is used. For example, use restriction information, or the user uses the service once the card information from the time gave an input to switch to the mode, it may be set so as to be provided up to 30 seconds from the touch.

Figure 9 is a view showing an example of a method for switching a smart card of Figure 1 in use mode.

Referring to Figure 9, the use restriction mode, or switched by the operation of the smart card 10, it can be switched by communication with the smart card 10 and the portable communication terminal 20.

More specifically, referring to (a) of Figure 9, the user can use the user interface unit 180 to switch the smart card 10 to the use mode.

For example, the user can switch the smart card 10 by using mode by touching the touch screen according to a predetermined pattern (184). Specifically, the smart card 10 may be converted to the time the left-half area of ​​the touch screen 184, the whole touch hayeoteul, use mode as shown in (a) of FIG.

At this time, the conditions for switching to the use condition is limited is previously set it may be stored in memory 130. It may also be a different setting condition according to the user's operation patterns. For example, if the user touch only half the touch screen 184, the number of possible use are set one circuit, a touch if the touch screen 184 as a whole, the available number of times may be set 2 times .

Further, the conditions for switching to use restricted state by the smart card 10. Smart card 10 when there is stored in the portable terminal 20, switch to the use mode, that work with a communication with the mobile terminal 20 is a portable is from terminal 20 may be delivered to the condition.

That is, the idea of ​​the invention, the smart card 10 is when a certain condition is satisfied according to the user's intention, and that that switch to the disabled state in capable of cards state, wherein said particular condition is the location or service, the stored do not limit the scope of the invention.

In this embodiment example it has been described that the transition to the use limitation state goes according to the area by touching the touch screen 184, for example, features of the present invention is not limited to this. For example, the transition to the use limitation condition can be achieved in various ways, such as password input, a fingerprint input, the input pattern by using the user interface unit 180.

In addition, although in this embodiment, that the shifting to a process of receiving a card selection from a user to the use restriction mode is carried out for example to be carried out separately as an example described, the scope of the invention is not limited to this. For example, the smart card 10 when the user selects the card can be driven to switch to the use mode by default. It can also be controlled so that the user switches to a use mode in the case of selecting a card in a specific way. For example, the smart card 10 when a user when touching the left-half area of ​​the touch screen 184, the card to be used is selected simply with a predetermined card, touch the right half region It may be controlled to switch to the selected group to a set card and at the same time use mode, the card to be used. Alternatively, the smart card 10 when a user if a touch to the touch screen, one-half the area of ​​the finger in the transverse direction of 184 has been selected, only the card to be simply used, the touch to the longitudinal direction, the card used in conjunction with the selection it may be controlled so as to switch to the mode.

On the other hand, switching to the use mode of the smart card 10 can also be made via the smart card 10 and the portable communication terminal 20.

Referring to (b) of Figure 9, the user operates the portable terminal 20 such as the communication unit 170 and the smartphone data communication is possible in the smart card 10 to switch the smart card 10 by using mode can.

Specifically, the user using the interface means provided in the portable terminal such as a button, a touch screen of the mobile terminal 20, a password input, location, type, drag pattern input, a fingerprint input, swipe input, a touch count input, a touch timing input and the like can be input using a mode switching command of the smart card through a variety of input methods. The mobile terminal 20 may forward the command signal to the information and if the user information matches one of the input, the use restriction mode is switched to the smart card 10 that has been set group.

The control unit 110 of the smart card 10 is used when the mode switching command is received from the portable terminal 20 via the communication unit 170, and switches to the use mode as described above.

10 is a flowchart showing a control method of a smart card according to one embodiment of the present invention.

10, the control unit 110 the user interface unit 180 may select to receive card information, select the card information of the card stage to be used by the user of the card information of the plurality of cards which are stored in the memory 130 through the performs (S1000).

For example, the user can swipe the touch screen 110, or group draw a predetermined pattern, or enter a password, or enter a predetermined code, which is matched with the card information, or select a specific location, or touch a particular area you can select the card you want to use a method like that.

When the user of the card, the selection is completed, the control section 110 performs the card information loading step (S2000) of loading the card information for the selected card from the memory 130. Although in this embodiment described with reference to card information loading step (S2000) is performed immediately after the card information selecting step (S1000) For example, the card information loading step (S2000) are but may be carried out at any time before the card is used .

When complete, the loading of the card selection, and the card information, the control section 110 performs the operating mode, receiving an input for switching use mode switching step (S3000). Here, the input used for mode switching may be made via the user interface unit 180 may be made via the smart card 10 and the portable communication terminal 20. For example, the user may enter the use mode switching command by operating in a manner predetermined for the touch-screen 184, or enter the use mode switching command on a touch screen of the mobile terminal (20).

In this embodiment example, to receive an input for a use mode switch separately from the input selection card for example, describes one type for use mode conversion as described above may be included in the input for the selected card. That is, the user may perform an input for the type and usage mode switch for selecting the card in one operation.

It may also be the type used for mode switching is carried out before the input to the card selected. That is, the control unit 110 may also be used after performing a mode switching step (S3000), first, card information selecting step (S1000) is performed.

The control unit 110 receives an input corresponding to the use mode switching, and performs use limitation information setting step of setting the use limit information (S4000) corresponding to the input. Here, the means to set the use restriction information is later used mode switching after the load the use restriction information corresponding to the input from the memory 130 or receive input from a user, how to receive transmission from the portable terminal 20, such as card It means for setting a condition for limiting use.

Here, the use restriction information may be set differently depending on the type used for mode switching. For example, a touch screen 184, such as when the user input of the first pattern, can be used only once set to use restriction information, and the second pattern of the case, to use 2 once set to the use-restriction information via a It can be.

Alternatively, the user may set up a direct-restriction information via a user interface unit 180 or the like. For example, the user enters the number 30, through the touch screen 184 may be a 30 seconds using the use constraint set, entering the number 60 may be within 60 seconds using a use limitation condition setting .

In this embodiment, one described as being used limitation information setting step (S4000) is used after the mode transition phase immediately performed (S3000) For example, features of the present invention is not limited to this. For example, the use restriction information set is set immediately prior to delivery and then the smart card 10 recognizes the card reader, card information can be utilized to determine whether or not enabled.

Then, the control unit 110 performs a smart card 10 or not, i.e. to recognize the card reader, the card reader recognizes that the stage is used (S5000). Specifically, the control unit 110 recognizes the card reader by which or recognize the like passing the supply or signal contacts or power through the exposed terminal portions 140, the head of the card reader through the head detection unit 160 detects can do.

When the card reader is recognized, the control unit 110 whether the current smart card 10 is a usable state, i.e., can be used to determine whether consistent with the use constraint set in the use restriction information setting step (S4000) whether It performs a determination step (S6000). The availability determination step (S6000) may be performed in a way that determines whether or not satisfy the condition at the time of the smart card 10 is used. For example, if under the smart card 10 is usable condition at the time when the card is recognized by the card reader, recognition step (S5000), of whether or not within a specific, usable whether the number of times the left, and the available time span one or more may be determined by conditions. Further, the state determining step is available (S6000) may be performed in a way to determine the available flags stored in memory 130. For example, or the smart card 10 is used, the use if the time as possible pass, the control unit 110 is capable of changing a value indicating available card status in the memory 130 as possible, whether the judging step is available ( S6000) to determine the said value may determine whether it is available.
