More specifically, for example, when the IC card C is placed against the antenna TP of the reader / writer RW installed in the automatic ticket gate, the transportation cost necessary for passing through the automatic ticket gate is indicated. Data is exchanged between the reader / writer RW and the IC card C by radio. Thereby, for example, the data indicating the balance stored in the memory unit 23 of the IC card C in a nonvolatile manner is updated by the control unit 21 of the IC card C. At this time, the control unit of the IC card C is used to exchange data between the reader / writer RW and the IC card C and to update the storage contents of the memory unit 23 as a result of the data exchange. The power required to be supplied to the first and second transmission / reception units 20 and the memory unit 23 is transmitted to the antenna AT1 of the IC card C from the antenna TP of the reader / writer RW. Covered by power induced in AT1.

  On the other hand, the IC card C and the display terminal DP exchange data stored in the memory unit 23 updated in the IC card C wirelessly in accordance with the wireless LAN standard. Thereby, the data stored in the memory unit 23 is transmitted to the display terminal DP, temporarily stored in the memory unit 32, and then displayed on the display D of the display terminal DP.

  At this time, in order to read the updated data from the memory unit 23 by the control unit 21 and to exchange data between the IC card C and the display terminal DP, the memory unit 23 and the control unit 21 of the IC card C, and The power that needs to be supplied to the second transmitting / receiving unit 22 is covered by the power induced in the antenna AT1 based on the principle of electromagnetic induction. In other words, the exchange of data between the above-mentioned reader / writer RW and the IC card C and the update of the stored contents of the memory unit 23, and the subsequent reading of the updated data from the memory unit 23 and the IC card C Of data between the display terminal DP and the display terminal DP is all completed within about 1 second when power is supplied to the IC card C by placing the IC card C over the antenna TP of the reader / writer RW. The The period during which power is supplied to the IC card C by placing the IC card C over the antenna TP of the reader / writer RW corresponds to an example of the “threshold time” according to the present invention.

  As a result of the operation of the IC card C and the like according to the above embodiment and the mode of power supply therefor, the storage contents of the memory unit 23 updated by placing the IC card C in the reader / writer RW are updated. It is transmitted to the display terminal DP and stored in the memory unit 32 while the IC card C immediately after it is being tricked. Then, the stored contents of the memory unit 32 are displayed on the display D by a predetermined timing or an operation on the operation unit 33 thereafter.

  Next, the processing of the information processing system S according to the embodiment, which is executed centering on the control unit 11, the control unit 21, and the control unit 31, will be described more specifically with reference to FIGS.

  In the process of the information processing system S, first, an authentication process for associating the IC card C according to the embodiment with the display terminal DP is executed. That is, as shown in FIG. 3A, first, the control unit 21 of the IC card C obtains power when the IC card C is deceived by a reader / writer RW at the user's hand, for example (step S1). As a result, communication based on the wireless LAN standard with the display terminal DP is started (steps S2 and S10). Next, the control unit 21 and the control unit 31 of the display terminal DP exchange authentication data necessary for the started communication (step S3, step S11), and the exchanged authentication data is transferred to the memory unit of the IC card C. 23 and the memory unit 32 of the display terminal DP are stored in a nonvolatile manner (steps S4 and S12). Through these authentication processes, thereafter, the above-described data exchange is executed only between the IC card C and the display terminal DP that are mutually authenticated.

  Next, the processing of the information processing system S according to the embodiment after the authentication processing is executed between the IC data C and the display terminal DP will be specifically described with reference to FIGS. 3B and 4. explain.

  As shown in FIG. 3B, the control unit 21 of the IC card C obtains power when the IC card C is deceived by the reader / writer RW provided in the automatic ticket gate, for example (step S20). Thus, the control unit 11 of the reader / writer RW and the control unit 21 of the IC card C start communication complying with the NFC standard. The control unit 11 and the control unit 21 exchange authentication data between the reader / writer RW-IC card C and perform necessary authentication processing, and then update data stored in the memory unit 23 (for example, the above traffic) (Data indicating expenses, etc.) are exchanged (step S15, step S21). Next, the control unit 21 updates the storage contents of the memory unit 23 using the update data received by the process of step S21 (step S22). The electric power necessary for the process of step S22 is supplied from the reader / writer RW via the antenna AT1 based on the principle of electromagnetic induction as described above.

  Next, the control unit 21 determines whether or not the display terminal DP authenticated by the authentication process shown in FIG. 3A is within a range where radio waves from the IC card C compliant with the wireless LAN standard can reach. Is confirmed (step S23, step S24). That is, immediately after the stored contents of the memory unit 23 are updated by the process of step S22, the control unit 21 transmits inquiry data for confirming the existence of the authenticated display terminal DP via the antenna AT2 (step S23). ). The inquiry data includes authentication data (authentication data for display terminal DP authentication) stored by the process of step S4 in FIG. As a result, when the control unit 31 of the display terminal DP receives the inquiry data (step S30), it is included in the authentication data stored in the memory unit 32 and the received inquiry data by the process of step S12 in FIG. The authenticated data is compared to determine whether or not the IC card C is an authenticated IC card C (step S31). If it is an authenticated IC card C (step S31; YES), that fact is indicated. The result data shown is transmitted to the IC card C (step S32). On the other hand, when it is not the authenticated IC card C in the determination in step S31 (step S31; NO), the control unit 31 ends the process as the display terminal DP according to the embodiment.

  Next, after transmitting the inquiry data by the process of step S23, the control unit 21 of the IC card C determines whether the result data has been transmitted from the display terminal DP by the process of step S32 (step S24). In the determination in step S24, for example, when the result data is not transmitted even after waiting for a predetermined time (step S24; NO), the display terminal DP does not exist within the reachable range of the radio wave from the antenna AT2. In that case, the control unit 21 ends the process as the IC card C according to the embodiment. On the other hand, when the result data is transmitted from the display terminal DP in the determination of step S24 (step S24; YES), the control unit 21 next displays the storage contents of the memory unit 23 updated by the process of step S22. Data is generated and transmitted to the display terminal DP (step S25).

  Next, when receiving the display data (Step S33), the control unit 31 of the display terminal DP determines whether or not the reception result is good. If the reception result is good, the control unit 31 transmits result data indicating that fact to the IC card C (step S34) and causes the memory unit 32 to store the received display data in a nonvolatile manner. Even when the reception result is not good, the control unit 31 transmits result data indicating that fact to the IC card C (step S34). Thereafter, when the reception result of the display data is good, the control unit 31 determines whether or not an operation for displaying the received display data on the display D is performed by the operation unit 33 (Step S31). S35). When the operation is performed in the determination in step S35 (step S35; YES), the control unit 31 displays the contents of the display data on the display D (step S36), and the display terminal DP according to the embodiment is displayed. The process ends. In addition, also when operation to the said display is not made in determination of step S35 (step S35; NO), the control part 31 complete | finishes the process as display terminal DP which concerns on embodiment. In the above embodiment, the content of the display data is displayed according to the operation on the operation unit 33. However, other than this, for example, after receiving the display data from the IC card C, at a predetermined timing. The content can be automatically displayed on the display D.

  On the other hand, the control unit 21 that has transmitted the display data by the process of step S25 has good transmission of the display data to the display terminal DP based on the result data transmitted from the display terminal DP by the process of step S34. It is determined whether or not the process has been completed (step S26). When it is determined in step S26 that the display data reception result at the display terminal DP is good based on the result data from the display terminal DP (see step S34) (step S26; YES), the control unit 21. Transmits a completion notification to that effect to the reader / writer RW (step S28), and ends the processing as the IC card C according to the embodiment. On the other hand, in the determination of step S26, when it is determined that the reception result of the display data at the display terminal DP is not good based on the result data from the display terminal DP (see step S34) (step S26; NO), control is performed. The unit 21 transmits an incomplete notification to that effect to the reader / writer RW (step S27), and returns to step S25 to retransmit the display data. Thereafter, the control unit 21 proceeds to the process of step S26.

  On the other hand, the control unit 11 of the reader / writer RW transmits the completion notification transmitted from the IC card C by the process of step S28 after the process of step S15 or the IC card C by the process of step S27. An incomplete notification is received (step S16). Next, the control unit 11 determines whether the received notification is a completion notification or an incomplete notification (step S17), and if it is a completion notification (step S17; YES), from the IC card C to the display terminal DP. For example, the display / sound on the reader / writer RW is notified to the user that the display data has been successfully transmitted (step S18), and then the processing as the reader / writer RW according to the embodiment is terminated. To do. On the other hand, if it is determined in step S17 that the notification is incomplete (step S17; NO), the display / sound on the reader / writer RW is notified to the user that the display data transmission to the display terminal DP has not been completed. Announcement is made (step S19), and then the processing as the reader / writer RW according to the embodiment is terminated.

  As described above, in particular, all of the processes shown in FIG. 3B except the process of step S35 and the process of step S36 are performed by placing the IC card C over the antenna TP of the reader / writer RW. This is completed while power is supplied to the card C from the reader / writer RW.

  Next, an example of information displayed on the display D by the process of step S36 will be described with reference to FIG.

  When the processing of the information processing system S according to the above-described embodiment is executed, for example, as shown in the display 100 illustrated in FIG. 4A, the balance and history state of each different IC card C are used as display data. It can be exchanged between the IC card C and the display terminal DP and displayed on the display D. Further, for example, as in the display 101 illustrated in FIG. 4B, even if the same IC card C is used, a more detailed usage history or the like is exchanged between the IC card C and the display terminal DP as display data. It is possible to display on the display D. Further, as in the display 102 illustrated in FIG. 4C, for example, at least the previous use history can be exchanged as display data between the IC card C and the display terminal DP and displayed on the display D. It becomes possible.

  As described above, according to the processing of the information processing system S of the embodiment, the update data from the reader / writer RW is received wirelessly, and before a predetermined time elapses from the reception timing (that is, the IC card) Within the time when C is deceived by the antenna TP of the reader / writer RW), the display data updated using the received update data is wirelessly transmitted to the display terminal DP. Therefore, the display data after the update using the received update data is transmitted to the display terminal DP within the time when the IC card C is deceived by the antenna TP of the reader / writer RW. Display data corresponding to the update data can be acquired at the display terminal DP, while eliminating the need for operations and operations. In addition, since it is not necessary for the IC card C itself to include the display D for displaying the display data, for example, the configuration of the IC card C can be simplified and the cost can be reduced.

  Further, since the display data is transmitted to the display terminal DP at a frequency different from the frequency used for receiving the update data from the reader / writer RW, the update data is clearly separated from the update data without a complicated configuration. Separately, display data can be transmitted to the display terminal DP.

  Furthermore, the power required to drive each component of the IC card C is acquired wirelessly from the reader / writer RW, and necessary processing is performed within the time when the IC card C is held by the antenna TP of the reader / writer RW. Complete. Therefore, the reception of the update data, the generation of the display data using the received update data, and the transmission of the display data are performed by the power acquired from the reader / writer RW. There is no need to provide a low cost, and there is no problem of cost reduction and safety at the time of disposal.

  In addition, since each component member as the IC card C is enclosed in a portable card-like casing, the portable IC card C can perform processing such as generation and transmission of display data.

  Furthermore, the content of the display data generated by the processing in the IC card C can be immediately confirmed on the external display terminal DP.

  Furthermore, since the transmission result of the display data to the display terminal DP is transmitted to the reader / writer RW for notification, the transmission result of the display data is quickly notified without providing the IC card C itself with a display or the like. be able to.

  In the above-described embodiment, if the display data is encrypted and transmitted to the display terminal DP, the display data can be prevented from leaking unintentionally.

  In the above-described embodiment, the display data is visually displayed on the display terminal DP. However, other than this, the contents of the display data can be notified by voice or the like.

  Further, in the above-described embodiment, the present invention is applied to the information processing system S including the reader / writer LR, the IC card C, and the display terminal DP. However, for example, the information is stored in one IC card. The present invention can also be applied to a game system in which data is shared by a plurality of portable game machines wirelessly connected to the IC card to change settings in each game machine. In this case, for example, if data indicating the game environment or game result in the first game machine is transmitted to the IC card and transferred to the second game machine within a predetermined threshold time, the entertainment property is real-time. A variety of games can be enjoyed on each game machine.
