Consists of. In this embodiment, the display control unit 120 and the non-contact IC card unit 110 are built in one non-contact IC card 100, and the display control unit 120 and the non-contact IC card unit 110 always correspond one-to-one. is doing.

  The non-contact IC card 100 is used for the purpose of authentication and settlement of, for example, an ID card, a credit card or a point card. The non-contact IC card 100 receives data from the reader / writer 10 and stores the received data. Further, the non-contact IC card 100 includes a display unit 130 and can display stored data on the outside. The data acquired by the non-contact IC card 100 and displayed on the display unit 130 is, for example, information about services using the non-contact IC card 100, fee information, user information, and the like.

  The power supply unit 102 supplies power to each component built in the non-contact IC card 100 such as the non-contact IC card unit 110, the display control unit 120, the display unit 130, and the electronic switch 140. In addition, although the non-contact IC card 100 of this embodiment shown using FIG. 1 supplies electric power to the non-contact IC card part 110, it is not limited to this example. For example, power may be supplied to the non-contact IC card unit 110 by a signal supplied from the reader / writer 10. At this time, the power supply unit 102 does not supply power to the non-contact IC card unit 110 but supplies power to the display control unit 120, the display unit 130, and the electronic switch 140.

  The non-contact IC card unit 110 is an example of an information processing unit, and performs control processing and arithmetic processing for realizing functions as the non-contact IC card 100. The non-contact IC card unit 110 is provided as a semiconductor integrated circuit (IC chip) inside the non-contact IC card 100.

  The non-contact IC card unit 110 has a storage unit 112. The storage unit 112 is, for example, an EEPROM (Electronically Erasable and Programmable Read Only Memory). The non-contact IC card unit 110 receives information included in the signal transmitted from the reader / writer 10 received by the loop antenna 144, and the storage unit 112 stores the information.

The non-contact IC card unit 110 performs various information processing based on a request (command information) from the reader / writer 10 or the display control unit 120. For example, when receiving a read processing request, the non-contact IC card unit 110 reads information stored in the storage unit 112 and sends the information to the reader / writer 10 or the display control unit 120. Further, the non-contact IC card unit 110 writes data in the storage unit 112 when receiving a write processing request.
The information stored in the storage unit 112 is, for example, information related to services using the contactless IC card 100, fee information, user information, and the like.

  When the non-contact IC card unit 110 receives a request (command information) from the reader / writer 10 or the display control unit 120, the non-contact IC card unit 110 simultaneously receives verification identification information (ID). The non-contact IC card unit 110 is an example of an identification information determination unit, and whether or not the verification identification information received from the reader / writer 10 or the display control unit 120 matches the identification information unique to the non-contact IC card unit 110. Judging. When the non-contact IC card unit 110 determines that the verification identification information matches the identification information unique to the non-contact IC card unit 110, the non-contact IC card unit 110 executes processing based on the above request. On the other hand, when it is determined that they do not match, the processing based on the above request is not executed.

  The display control unit 120 controls display on the display unit 130. The display control unit 120 acquires information stored in the storage unit 112 from the non-contact IC card unit 110 via the electronic switch 140 and displays the information or information generated based on the information on the display unit 130. Let

  The display control unit 120 controls the electronic switch 140 based on the detection result of the magnetic field supplied by the magnetic field sensor 142. For example, the display control unit 120 controls the electronic switch 140 to switch the connection destination of the non-contact IC card unit 110 to the loop antenna 144 when a carrier wave is detected by the magnetic field sensor 142. By this control, the non-contact IC card 100 can communicate with the reader / writer 10. On the other hand, since the display control unit 120 is disconnected from the non-contact IC card unit 110, the display control unit 120 cannot acquire information from the non-contact IC card unit 110.

  Further, the display control unit 120 controls to switch the connection destination of the non-contact IC card unit 110 to the display control unit 120 when the magnetic field sensor 142 does not detect a carrier wave. By this control, the non-contact IC card 100 cannot communicate with the reader / writer 10. On the other hand, since the display control unit 120 is connected to the non-contact IC card unit 110, information can be acquired from the non-contact IC card unit 110. The display control unit 120 is an example of a switching control unit.

  The display control unit 120 includes a storage unit 125. The storage unit 125 is, for example, an EEPROM (Electronically Erasable and Programmable Read Only Memory). The display control unit 120 receives information from the non-contact IC card unit 110, and the storage unit 125 stores the information. Thereby, the display control unit 120 can display the information acquired from the non-contact IC card unit 110 on the display unit 130 at an arbitrary timing. The storage unit 125 has the same identification information for collation as the unique identification information of the non-contact IC card unit 110 in advance.

  The display unit 130 is, for example, an LCD (Liquid Crystal Display), an organic EL display (Organic Electro-Luminescence Display), and the like, and is a display device that can display characters and images. The display unit 130 may have a shape and a size that demonstrate the convenience of the contactless IC card 100 as a card.

  The electronic switch 140 is an example of a switching unit, and is a switch circuit that switches a connection destination of signal input / output terminals of the non-contact IC card unit 110. The electronic switch 140 is, for example, a three-terminal switch, and connects the non-contact IC card unit 110 to either the loop antenna 144 or the display control unit 120. The electronic switch 140 is controlled by the display control unit 120. The electronic switch 140 may have any configuration and scale, but it is preferable that the electronic switch 140 can exhibit the convenience of the contactless IC card 100 as a card.

  The magnetic field sensor 142 is an example of a detection unit, is provided in the vicinity of the loop antenna 144, and detects a magnetic field change that occurs in the vicinity of the loop antenna 144. The magnetic field sensor 142 sends the detection result to the display control unit 120. The magnetic field sensor 142 is intended to detect a magnetic field signal transmitted from the reader / writer 10, and the detection capability of the magnetic field change may be approximated or matched with the loop antenna 144. For example, the magnetic field sensor 142 has a coil shape similar to the loop antenna 144 and is arranged so as to be insulated from the loop antenna 144 while being insulated.

  The loop antenna 144 is an example of a receiving unit, and receives a magnetic field signal. The loop antenna 144 detects and receives, as a magnetic field signal, a magnetic field change inside the loop due to an electromagnetic wave (carrier wave) transmitted from the reader / writer 10 adjacent to the non-contact IC card 100. The loop antenna 144 sends the received signal to the non-contact IC card unit 110 via the electronic switch 140.

Next, the display control unit 120 of this embodiment will be described in detail with reference to FIG. FIG. 2 is a block diagram showing the display control unit 120 of the non-contact IC card 100 according to the present embodiment.
The display control unit 120 includes a condition determination unit 121, an electronic switch control unit 122, a display data transmission / reception unit 123, a storage control unit 124, a storage unit 125, and the like.

  The condition determination unit 121 determines whether or not the detection result detected by the magnetic field sensor 142 satisfies a predetermined condition. For example, the predetermined condition is whether or not a magnetic field change is detected. When the magnetic field change is detected, it is determined that the condition is satisfied. When the magnetic field change is not detected, it is determined that the condition is not satisfied.

  The electronic switch control unit 122 controls the electronic switch 140 according to the determination result of the condition determination unit 121. For example, when the condition determination unit 121 detects a carrier wave and determines that the condition is satisfied, the electronic switch 140 is controlled to switch the connection destination of the non-contact IC card unit 110 to the loop antenna 144. On the other hand, when it is determined by the condition determination unit 121 that the carrier wave is not detected and the condition is not satisfied, control is performed to switch the connection destination of the non-contact IC card unit 110 to the display control unit 120.

  The display data transmission / reception unit 123 receives information such as display data and data conversion information from the non-contact IC card unit 110 via the electronic switch 140 and sends display information to the display unit 130.

The storage control unit 124 performs control to write information such as service information, fee information, and user information in the storage unit 125, and reads information such as service information, fee information, and user information stored in the storage unit 125. Control.
The series of processes described above may be performed by hardware or may be realized by software processing using a program on a computer.

(Operation of one embodiment)
Next, the operation of the non-contact IC card 100 according to the present embodiment will be described with reference to FIGS.

  First, switching of the electronic switch 140 will be described with reference to FIG. FIG. 3 is a flowchart showing switching of the electronic switch 140. Normally, by bringing the non-contact IC card 100 close to the reader / writer 10, the non-contact IC card 100 detects a change in the magnetic field, and accordingly, the electronic switch 140 switches the connection destination.

  First, the magnetic field sensor 142 built in the non-contact IC card 100 detects a change in the magnetic field (step S11). Next, it is determined whether or not the condition determination unit 121 of the display control unit 120 satisfies a predetermined condition (steps S12 and S13). When the predetermined condition is satisfied, for example, when a carrier wave from the reader / writer 10 is detected, the display control unit 120 connects the electronic switch 140 to the loop antenna 144 (step S16). At this time, the non-contact IC card 100 can receive data from the reader / writer 10 (step S17). The storage unit 112 of the non-contact IC card unit 110 stores data received from the reader / writer 10.

  On the other hand, when the predetermined condition is not satisfied, for example, when the carrier wave is not detected from the data from the reader / writer 10, the display control unit 120 connects the electronic switch 140 to the display control unit 120 (step S14). At this time, the non-contact IC card 100 can send data from the non-contact IC card unit 110 to the display control unit 120 (step S15). And the memory | storage part 125 of the display control part 120 memorize | stores the data acquired from the non-contact IC card part 110. FIG.

  As described above, switching of the electronic switch 140 changes depending on whether or not a carrier wave is detected, and the non-contact IC card 100 receives data from the reader / writer 10 or controls display of data stored in the non-contact IC card unit 110. To the unit 120. Thereby, it is possible to send data to the display control unit 120 and display information on the display unit 130 while utilizing the existing non-contact IC card unit 110.

  Next, a process of writing identification information (hereinafter, also referred to as an IC card ID) unique to the non-contact IC card unit 110 in the display control unit 120 will be described with reference to FIG. FIG. 4 is a flowchart showing processing for writing identification information unique to the non-contact IC card unit 110 (hereinafter also referred to as IC card ID) in the display control unit 120. For example, this processing may be performed before shipment when the non-contact IC card 100 is manufactured.

  First, it is confirmed that the storage unit 125 of the display control unit 120 is in the initial state (step S21). Then, the display control unit 120 transmits a polling command to the non-contact IC card unit 110 (step S22). The non-contact IC card unit 110 transmits the IC card ID to the display control unit 120 in response to the polling command from the display control unit 120 (step S23). As a result, the display control unit 120 can acquire the IC card ID, and writes the acquired IC card ID in the storage unit 125 (step S24).

  Through the above process, the display control unit 120 stores the IC card ID in advance as verification identification information (verification ID). As a result, when the display control unit 120 performs a request process on the non-contact IC card unit 110, if the IC card ID as the verification ID is read from the storage unit 125, the polling command is not transmitted and the non-contact is performed. Request processing specifying the IC card ID for the IC card unit 110 can be started.

  Next, a request process performed by the display control unit 120 for the non-contact IC card unit 110 will be described with reference to FIG. FIG. 5 is a flowchart showing a request process performed by the display control unit 120 for the non-contact IC card unit 110. For example, the display control unit 120 requests the non-contact IC card unit 110 to read data stored in the storage unit 112, or the display control unit 120 performs non-processing. This is a process of requesting a writing process so that the contact IC card unit 110 writes data to the storage unit 112.

  First, the display control unit 120 starts a processing request to the non-contact IC card unit 110 (step S31). At this time, if the above-described initial setting process described with reference to FIG. 4 has been completed, the display control unit 120 stores the IC card ID in the storage unit 125 in advance as a verification ID. Accordingly, the display control unit 120 reads the IC card ID from the storage unit 125 (step S32).

  Next, the display control unit 120 transmits a command specifying the IC card ID (step S33). Thereby, the display control unit 120 performs a request process for the non-contact IC card unit 110. The non-contact IC card unit 110 confirms the IC card ID received together with the command (step S34). Since the IC card ID received from the display control unit 120 is an ID transmitted to the display control unit 120 by the non-contact IC card unit 110 in advance, it matches the own IC card ID. Therefore, the non-contact IC card unit 110 always responds to the display control unit 120 (step S35) and executes the command received from the display control unit 120.

  As described above, in the present embodiment, the display control unit 120 has a collation ID that is the same as the unique IC card ID of the non-contact IC card unit 110 in advance, and the collation ID and the command are both non-contact IC cards. Can be sent to section 110. That is, conventionally, when a request process is performed on the non-contact IC card unit 110, a polling command process is always required. However, according to the present embodiment, the display control unit 120 is connected to the non-contact IC card unit 110. When request processing is performed, polling command processing for the non-contact IC card unit 110 is not required.

  This is because the display control unit 120 and the non-contact IC card unit 110 are built in one non-contact IC card 100, and the display control unit 120 and the non-contact IC card unit 110 always correspond one-to-one. This is possible. That is, the other party to whom the display control unit 120 transmits a command is always the same non-contact IC card unit 110, and therefore the IC card ID unique to the non-contact IC card unit 110 received by the polling command process is always the same. Therefore, as described above, the polling command process can be omitted. As a result, the display control unit 120 does not need to transmit a polling command or receive an IC card ID every time request processing is performed. For this reason, the current consumption required for the polling command processing becomes unnecessary, and the power consumed by the non-contact IC card 100 can be reduced.

  Next, with reference to FIG. 6, a request process performed by the reader / writer 10 for the non-contact IC card unit 110 will be described. FIG. 6 is a flowchart showing a request process performed by the reader / writer 10 for the non-contact IC card unit 110. In this process, for example, the reader / writer 10 requests the non-contact IC card unit 110 to read out data stored in the storage unit 112, or the reader / writer 10 performs non-contact IC card reading. This is a process of requesting the card unit 110 to write data so as to write data to the storage unit 112.

  First, the reader / writer 10 starts a processing request to the non-contact IC card unit 110 (step S41). At this time, the reader / writer 10 needs to identify a plurality of non-contact IC cards 100, and therefore performs a polling command process. That is, the reader / writer 10 transmits a polling command to the non-contact IC card unit 110 (step S42). In response to the polling command from the reader / writer 10, the non-contact IC card unit 110 transmits the IC card ID to the display control unit 120 (step S43). As a result, the reader / writer 10 can acquire the IC card ID, and writes the acquired IC card ID in the storage unit 125 (step S44).

  Next, the reader / writer 10 designates the IC card ID and transmits a command (step S45). As a result, the reader / writer 10 performs a request process on the non-contact IC card unit 110. The non-contact IC card unit 110 confirms the IC card ID received together with the command, and determines whether or not the IC card ID matches its own unique IC card ID (step S46). When the IC card ID received together with the command matches its own unique IC card ID, the non-contact IC card unit 110 responds to the reader / writer 10 (step S47). Thereby, the non-contact IC card unit 110 executes the command received from the reader / writer 10. On the other hand, if the IC card ID received together with the command does not match its own unique IC card ID, the non-contact IC card unit 110 does not respond (step S48).

  As described above, according to the non-contact IC card 100 of the present embodiment, the reader / writer 10 outside the non-contact IC card 100 performs a polling command process on the non-contact IC card unit 110 and then performs a request process. On the other hand, the built-in display control unit 120 can perform request processing on the non-contact IC card unit 110 without performing polling command processing. Therefore, the processing procedure can be reduced, and the power consumed by the display control unit 120 built in the non-contact IC card 100 can be reduced.

  The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings, but the present invention is not limited to such examples. It is obvious that a person having ordinary knowledge in the technical field to which the present invention pertains can come up with various changes or modifications within the scope of the technical idea described in the claims.
