Application-related data such as the balance of the read electronic money is automatically displayed on the sub-display 22 of the display unit 114, for example.

  In the data access information storage unit 138, a plurality of access information storage areas 138A, 138B, and 138M in which the data access information is stored are set for each of a plurality of electronic wallet applications registered in the mobile phone 10. . In each access information storage area 138A, 138B, 138M, for example, data access information is written when an electronic wallet application is preinstalled and registered, or when an electronic wallet application is downloaded and registered. The setting of the access information storage area and the writing of the data access information may be performed for all of the plurality of electronic wallet applications registered in the mobile phone 10, or may be performed for some of the plurality of electronic wallet applications. Also good. For example, only the electronic wallet application designated by the content supplier supplying the electronic wallet application program may set the access information storage area or write the data access information. The access information storage area may be set and the data access information may be written only for the electronic wallet application designated by the user of the mobile phone 10 using the electronic wallet application.

  As the data access information, for example, a system code for identifying an electronic wallet system used by the electronic wallet application, a service code (area code) for identifying the electronic wallet application, and application-related data such as a balance are stored. The block No. for identifying the current block, the display target service name, the balance unit (for example, “Yen”, “US $”), etc. are written. Among these data access information, a system code, a service code (area code), and a block number are used to specify a storage area in the electronic wallet chip unit (IC chip) 116 in which balance data as application-related data is stored. Used as area designation information.

  Here, when a predetermined key operation (for example, a long press operation of the side key 23) is performed while the mobile phone 10 is in a standby state in which the casing is closed, the main control unit 110 causes the data access information storage unit 138 to The data access information of the electronic wallet application A in the first access information storage area 138A is read. Then, the main control unit 110 accesses the application data storage area 137A corresponding to the electronic wallet application A of the application-related data storage unit 137 based on the read data access information, and stores the balance data of the electronic wallet application A. read out. The read balance data is displayed on the sub display 22 of the display unit 114 together with the service name and unit read from the access information storage area 138A. Further, when a predetermined key operation (for example, a long press operation of the side key 23) is performed, the balance data is read and displayed for the electronic wallet application B and the electronic wallet application M.

  FIG. 8 is a flowchart showing an example of control when registering an electronic wallet application in the mobile phone configured as described above. First, upon receiving an operation for registering an electronic wallet application acquired by downloading from a content supplier's server or the like (S101), the main control unit 110 receives the program body of the electronic wallet application and a property information file as an application program. The data is stored in the storage unit 136 (S102).

  Next, based on the property information of the electronic wallet application, the main control unit 110 determines whether or not to allow display of balance data when the electronic wallet application is not executed (S103). Whether or not to allow the balance data to be displayed is determined based on whether or not a predetermined attribute “MIDlet-Wallet View” exists in the JAD file to which the property information is written, for example, in the case of a JAVA application. If “MIDlet-Wallet View” exists, it is determined that display of the balance data is allowed.

Next, when determining that the balance data is allowed to be displayed, the main control unit 110 accesses the application-related data storage unit 137 from the property information of the electronic wallet application when the electronic wallet application is not activated. Data access information for reading application-related data such as the balance of electronic money is read (S104). For example, in the case of a JAVA application, the system code, service code (area code), block number, display target service name, and balance unit written in the predetermined attribute “MIDlet-Wallet View” of the JAD file are read out. . The read data access information is stored in a free access information storage area of the data access information storage unit 138 (S105).
If there are a plurality of electronic wallet applications to be registered (Yes in S106), steps S102 to S105 are repeated.

FIG. 9 is a flowchart showing an example of control when displaying a balance for a registered electronic wallet application in the mobile phone configured as described above.
First, the main control unit 110 detects, for example, a long press of the side key 23 as a predetermined key operation in a state where the housing is closed as shown in FIG. 2B when the electronic wallet application is not executed. When accepted (S201), the first access information storage area of the data access information storage unit 138 is accessed, and the data access information is read from the access information storage area (S202). For example, the system code, service code (area code), block number, display target service name, and balance unit are read out.

  Next, the main control unit 110 accesses the electronic wallet chip unit (IC chip) 116 based on the data access information read from the data access information storage unit 138 (S203), and the application related data specified by the data access information Current balance data that is application-related data of the electronic wallet application is read from a predetermined data area of the storage unit 137 (S204). For example, the service code (area code) in the data access information and the service code (area code) written in the application-related data storage unit 137 in the electronic wallet chip unit (IC chip) 116 are collated. Read the matching balance data.

,
Next, the main control unit 110 displays the balance data read from the data access information storage unit 138 on the sub display 22 together with the display target service name read from the data access information storage unit 138 and the unit data of the balance. Thus, the display unit 114 is controlled (S205). For example, as shown in FIG. 10A, the display target service name “AAA”, the balance data “7,777”, and the unit “yen” are controlled to be displayed on the screen of the sub-display 22. .

  Next, when the main controller 110 further detects and accepts, for example, a long press of the side key 23 as a predetermined key operation (S206), the main controller 110 determines whether or not there is an electronic wallet application for the next balance display target (S206). S207). Here, if there is an electronic wallet application that is the next balance display target, steps S202 to S205 are repeated to display the balance. For example, as shown in FIG. 10B, the display target service name “BBB”, balance data “540”, and the unit “Pt” are displayed for the next electronic wallet application to be displayed. Control.

  In the balance display control example shown in FIG. 9, when there are a plurality of balance display target electronic wallet applications, the balance of the next electronic wallet application is controlled to be sequentially displayed based on a predetermined key operation. The balance of a plurality of electronic wallet applications may be controlled to be sequentially displayed every time a predetermined time elapses without using a key operation.

  As described above, according to the present embodiment, the balance data stored by the execution of the electronic wallet application is displayed on the sub-display 22 by a predetermined key operation (for example, long press of the side key 23) without starting the electronic wallet application. It can be confirmed by displaying on the screen.

  According to this embodiment, when an application program is downloaded and registered, data access information corresponding to the application program to be registered is automatically downloaded from the server and stored in the data access information storage unit 138. This eliminates the need for the user to individually download and save the data access information.

  Further, according to the present embodiment, by referring to the data access information (storage area designation information) such as the system code, service code (area code) and block No., the data access information (storage area designation information) The balance data of a desired electronic wallet application can be read out from a predetermined storage area in the designated electronic wallet chip unit (IC chip) 116 and displayed.

  In addition, according to the present embodiment, when a plurality of electronic wallet applications to be displayed for balance are registered, a plurality of balance data corresponding to each electronic wallet application is stored in a predetermined key operation (for example, side key 23) by the user. Each balance data can be easily confirmed by sequentially outputting in response to a long press of the key.

  Further, according to the present embodiment, the casing is closed so that the screen of the main display 19 is covered in an invisible manner and the screen of the sub display 22 provided separately from the main display 19 is exposed in a visible manner. Even in the closed state, the balance data can be displayed and confirmed on the screen of the sub-display 22.

Note that the mobile phone according to the above-described embodiment may be provided with a USIM (Universal Subscriber Identity Module) card, for example, as a storage medium for storing user information that stores unique user information for each user. Good. In the case of this mobile phone, the main control unit 110 associates the user information read from the attached USIM card with the balance data in the application-related data storage unit 137 or the data access information in the data access information storage unit 138. It is determined whether or not the stored user information matches. If the two pieces of user information do not match, control is performed so that balance data is not displayed even if a predetermined key operation such as a long press of the side key 23 is performed.
When the user is switched in this cellular phone, the USIM card of the user who has activated and used the electronic wallet application that involves saving balance data is removed, and the USIM card of another user is attached. Then, the user information read from the attached USIM card and the user information stored in association with the balance data in the application-related data storage unit 137 or the data access information in the data access information storage unit 138 are included. It is determined whether or not they match. Here, if both pieces of user information do not match, the user before the switching is controlled by controlling the balance data not to be output even if there is a balance data display instruction by the user after the switching. It is possible to prevent the balance data stored at this time from being confirmed by the user after the switching.

In the above embodiment, the cellular phone 10 has been described as an example, but the present invention can be similarly applied to other mobile communication terminals.
Further, the present invention can be similarly applied when displaying application-related data other than balance data. For example, the present invention can be similarly applied to the case where the latest score of the game is displayed without starting the game application.
The output of application related data when the application is not executed may not be displayed on the display. For example, application-related data may be output by voice.
