[0027]
In the present embodiment, when the non-contact communication function is enabled, the face photograph image 40 of the authorized user is displayed on the liquid crystal display unit 13 as shown in FIG. By comparing the face and the face photograph image, it is determined whether or not the user is a regular user, and settlement such as electronic commerce can be executed. Before using the non-contact communication function, the user's face photograph is taken by the imaging unit 11 and the image data is stored in the storage unit 12. The image data of the face image of the authorized user is locked so that it is not changed by a third party by setting a password.
[0028]
First, in the normal state, it is assumed that the non-contact communication function of the mobile phone device 10 is invalid (step S201). The control unit 21 sets the function of the non-contact communication unit 14 to be invalid as a normal state. In this normal state, electronic commerce by non-contact communication is impossible.
[0029]
When the user performs electronic commerce by non-contact communication, the operation mode is switched by operating the key operation unit 15. When an operation input for enabling the non-contact communication function of the mobile phone device 10 is performed by the key operation unit 15, the operation mode is switched so that the non-contact communication unit 14 is activated and operable (step S202). And the control part 21 displays the image data of the regular user's face photograph stored in the memory | storage part 12 on the liquid crystal display part 13 (step S203).

As described above, when the non-contact communication function is in the on state, the face image of the authorized user is displayed on the liquid crystal display unit 13, and the non-contact communication standby state is set.
[0030]
In actual electronic commerce, the user shows the facial photograph image displayed on the liquid crystal display unit 13 of the mobile phone device 10 to the settlement person, and the settlement person confirms the user's face and facial photograph and is authorized. Determine if you are a user. When the face image of the authorized user matches the face of the user, and the user is determined to be an authorized user, the settlement person makes a settlement at a settlement terminal including a non-contact communication reader / writer device. The confirmation OK input operation is performed by operating the execution button or the like. If there is an operation input for user confirmation by the settlement person (step S205), electronic commerce by non-contact communication can be executed.
[0031]
The non-contact communication unit 14 of the mobile phone device 10 starts communication in response to a communication request from the payment terminal, exchanges data with the payment terminal, and performs payment processing for electronic commerce (step S206). . At this time, the contactless communication unit 14 updates settlement history information and value information and stores them in the storage unit.

It can be easily determined. In this case, execution of electronic commerce using the non-contact communication function is not permitted, and it is possible to prevent the settlement process by non-contact communication contrary to the intention of the authorized user from being executed.
[0035]
In the above-described embodiment, an example in which the imaging unit 11 mounted on the mobile phone device is used as a means for acquiring face photograph image data for proving that the user is a regular user has been described. This is not a limitation. For example, it may be obtained by connecting a cellular phone device to a computer and transferring image data of a face photograph taken by another camera or the like.
[0036]
When returning to the normal state with the non-contact communication function disabled, in addition to the mode switching operation by the user as described above, after the non-contact communication is completed and a predetermined time has elapsed, the control unit 21 automatically It is good also as operation | movement which erase | eliminates a face photograph image and invalidates a non-contact communication function.
[0037]

At this time, the control part 32 detects the communication start of non-contact communication in the non-contact communication part 14 (step S303). Then, the control unit 32 displays the image data of the regular user's face photograph stored in the storage unit 12 on the liquid crystal display unit 13 (step S304). When the start of non-contact communication is detected in this way, a face photograph image of the authorized user is displayed on the liquid crystal display unit 13.
[0046]
In actual electronic commerce, the user shows the facial photograph image displayed on the liquid crystal display unit 13 of the mobile phone device 30 to the settlement person, and the settlement person confirms the user's face and facial photograph and is authorized. Determine if you are a user. When the face photograph of the authorized user matches the face of the user, and the user is determined to be an authorized user, the settlement person can use the payment terminal including the non-contact communication reader / writer device 50 and the like. The confirmation OK input operation is performed by operating the settlement execution button. When there is an operation input for user confirmation by the settlement person (step S305), electronic commerce by non-contact communication can be executed.
[0047]
The non-contact communication unit 14 of the mobile phone device 30 starts communication in response to a communication request from the payment terminal, exchanges data with the payment terminal, and performs payment processing for electronic commerce (step S306). . At this time, the contactless communication unit 14 updates settlement history information and value information and stores them in the storage unit.
[0048]
When the electronic commerce is finished, the non-contact communication between the non-contact communication unit 14 and the non-contact communication reader / writer device 50 is finished (step S307). The control unit 32 detects the end of non-contact communication based on the presence or absence of a magnetic field (step S308). Then, the control unit 32 erases the image data of the regular user's face photograph displayed on the liquid crystal display unit 13 (step S308). Thereafter, the normal state is restored. Thus, when the end of non-contact communication is detected, the display of the face photograph image of the authorized user on the liquid crystal display unit 13 is erased.
[0049]
If a third party tries to make unauthorized use, the facial photo image displayed on the liquid crystal display unit 13 of the mobile phone device 30 and the user's face do not match when the settlement person confirms, so unauthorized use in advance It can be easily determined. In this case, execution of electronic commerce using the non-contact communication function is not permitted, and it is possible to prevent the settlement process by non-contact communication contrary to the intention of the authorized user from being executed.
[0050]
As described above, in the second embodiment, when the start of communication of non-contact communication with the reader / writer device 50 for non-contact communication is detected, the face photograph of the authorized user is displayed on the display unit, thereby performing electronic commerce. Whether or not the user is an authorized user can be easily confirmed in advance, and electronic commerce can be permitted only when the authorized user is authenticated. For this reason, when the mobile phone device is lost or stolen, the use of the non-contact communication function other than the authorized user can be prohibited, so that unauthorized use by a third party can be prevented.
[0051]
As the non-contact communication means, a case of using a magnetic field modulation proximity or proximity wireless communication function similar to that of a non-contact IC card has been shown.
