FIG. 2 is a flowchart for explaining the registration process, which is realized by the control unit 80 performing a control operation according to a control program or control data stored in the storage unit 60. This process is started by a request from the user through the operation unit 40.

  First, in step 2a, the control unit 80 controls the display unit 30 to perform a display asking for a registration method of an effective area, and proceeds to step 2b. Here, as an example of a display asking for a registration method of an effective area, a display such as “Do you want to select an effective area from the area list? Or do you want to set the current position as an effective area?” Can be considered.

  In step 2b, the control unit 80 determines whether or not the user instruction through the operation unit 40 is a selection from the area list. Here, if the user's instruction is selection from the area list, the process proceeds to step 2f. On the other hand, if the instruction is not selection from the area list, but is an instruction to set the current position as an effective area. The process proceeds to step 2c.

In step 2c, the control unit 80 controls the communication unit 10, communicates with the GPS server 300 via the radio base station 200, requests the GPS server 300 for the current location information of the mobile radio terminal device, and performs step 2d. Migrate to

Then, the detected area is recorded as effective area data in the storage unit 60, and the process ends.

On the other hand, in step 2f, the control unit 80 displays a region list based on the region table stored in the storage unit 60 on the display unit 30, and proceeds to step 2g.
In step 2g, the control unit 80 receives a region selection request from the region list displayed in step 2f based on a user operation through the operation unit 40, and proceeds to step 2h.
In step 2h, the control unit 80 records the region selected by the user in step 2g in the storage unit 60 as effective region data, and ends the process.

  Next, an operation in the case of performing payment with a credit card or electronic money, locking / unlocking a key, etc. using the non-contact type IC card 70 will be described. FIG. 3 is a flowchart for explaining the valid area confirmation processing performed in accordance with the above operation, in which the control unit 80 performs a control operation according to the control program and control data stored in the storage unit 60. To achieve. This process is repeatedly executed.

  First, in step 3a, the control unit 80 monitors the operating state of the non-contact type IC card 70 and determines whether or not communication with the IC card reader / writer 400 has been performed. If it is detected that communication has been performed, the process proceeds to step 3b. On the other hand, if it cannot be detected that communication has been performed, the operation state of the non-contact IC card 70 is monitored again.

  In step 3b, the control unit 80 determines whether or not the non-contact type IC card 70 is locked so that it cannot be used. Here, when it is detected that the non-contact type IC card 70 is locked, the process is terminated. On the other hand, when it is not possible to detect that the contactless IC card 70 is locked, the process proceeds to step 3c.

Note that the mobile radio terminal device may include a GPS receiver, and the result of positioning based on received signals from a plurality of GPS satellites may be used as position information.

  In step 3f, the control unit 80 associates the history of the authentication process performed in step 3c, that is, the usage information indicating the usage history of the non-contact type IC card 70 with the position information acquired in step 3d or step 3e. The data is recorded on the non-contact type IC card 70, and the process proceeds to Step 3g.

  In step 3c, when the non-contact type IC card 70 autonomously stores the usage information, the non-contact type IC card 70 stores the positional information in association with the IC card reader / writer 400, or The control unit 80 may output the position information acquired in step 3e to the non-contact type IC card 70, and the non-contact type IC card 70 may store the position information in association with the usage information.

In step 3g, the control unit 80 compares the valid area data stored in the storage unit 60 with the position information acquired by the non-contact type IC card 70 from the IC card reader / writer 400 or the position information acquired in step 3e. Thus, it is determined whether or not the location where the mobile radio terminal apparatus is currently located is an effective area. If it is detected that the area is valid, the process is terminated. On the other hand, if it is detected that the area is not valid, the process proceeds to step 3h.

  As described above, in the mobile radio terminal device having the above-described configuration, when the non-contact type IC card 70 is used, the location information of the mobile radio terminal device is acquired, and the current location is set in advance. If not, the non-contact type IC card 70 is locked so that it cannot be used.

  Therefore, according to the mobile wireless terminal device having the above-described configuration, the contactless IC card 70 can be used if the illegal use is performed, for example, in a place where the original user cannot be used due to theft or a place where the use is not permitted. Because it disappears, convenience improves.

  In general, the non-contact type IC card 70 is equipped with a high-performance CPU (Central Processing Unit) and performs complex processing, and thus has higher resistance to counterfeiting and alteration than a magnetic credit card or the like. Recently, the internal structure may be illegally observed by various attacks such as side channel attacks. However, even if forgery or alteration is carried out, it can be used only in a specific area, so that the effect of preventing unauthorized use is high.

Further, for example, a configuration in which some components are deleted from all the components shown in the embodiment is also conceivable. Furthermore, you may combine suitably the component described in different embodiment.

  As an example, for example, in the above-described embodiment, when the non-contact type IC card 70 is used in a region other than a pre-permitted area, the non-contact type IC card 70 cannot be used. When the non-contact type IC card 70 is used outside the pre-authorized area, the control unit 80 may be locked so that the original communication function of the mobile radio terminal device cannot be used.

  According to this, even in the case of theft, for example, unauthorized communication can be prevented. Recently, there is a mobile communication system in which a subscriber is identified and operated by a network using a SIM (Subscriber Identity Module) card. In the case of a mobile radio terminal used in this system, the control unit 80 Since the SIM locks, unauthorized communication can be prevented.

  In step 3f, the usage information and the position information are associated with each other and recorded in the non-contact type IC card 70. By using this information, a place used in the past is displayed on the display unit 30. You may make it alert | report to a user. The map information is downloaded from a map server provided on the network, and places used in the past are displayed on this map.

  Further, the current position information is acquired, and this is compared with the position information stored in the non-contact type IC card 70, so that the location used in the past close to the current position is displayed on the display unit 30 to notify the user. It may be. Also in this case, map information is downloaded from a map server provided on the network, and places used in the past are displayed on this map.

Further, in an area (building) where there are a limited number of entrances / exits, the contactless IC card 70 and the IC card reader / writer 400 communicate with each other when passing through the entrance / exit, and the usage history and position information are contactless. Recorded on the IC card 70. According to this, it is possible to manage entry / exit of a specific place based on the recorded information.
In addition, it goes without saying that the present invention can be similarly implemented even if various modifications are made without departing from the gist of the present invention.
