  The non-contact IC card 39 is described as being built in the mobile phone 2, but the mobile phone 2 is provided with an insertion port for the non-contact IC card 39, and the non-contact IC card 39 is not in contact with the insertion port. When the IC card 39 is inserted, the non-contact IC card 39 may be connected to the control unit 40 of the mobile phone 2 via the card interface and the control line (= the non-contact IC card 39 is externally attached). You may make it connect with the said mobile telephone 2 in the form.).

[System operation]
[Storage of user identification image for mobile phone 2]
First, when using this automatic ticket gate system, an image (image) that can be identified by the user is stored in the non-contact IC card 39 of the mobile phone 2 owned by the user. Specifically, the user downloads a desired image as shown in, for example, FIG. 4A or FIG. 4B into the memory 38 by downloading from a desired website or capturing an image with the camera unit 35. .

  Next, the user designates an operation for storing the image captured in the memory 38 in the non-contact IC card 39 by operating the operation unit 36. When this designation is made, the control unit 40 transfers the image stored in the memory 38 to the non-contact IC card 39. When this transfer is performed, the control unit 42 of the non-contact IC card 39 stores and controls the transferred image in the icon image storage area 45 of the memory 43 as a “user identification image”.

  Thereby, when the user passes the automatic ticket gate 1, the “user identification image” stored in the non-contact IC card 39 is displayed on the display unit 15 of the automatic ticket gate 1 together with the settlement information. System operation is possible.

  In this example, the description will be made on the assumption that an image is stored in the non-contact IC card 39 as information that can be identified by the user. This is because other information such as characters and symbols is used instead of the image. But you can. That is, any information may be used as long as the information can be identified as information stored in the user's own non-contact IC card 39.

[Operation of automatic ticket gate 1]
The flowchart of FIG. 5 shows the flow of the operation for displaying the “user identification image” together with the payment information, which is executed in the automatic ticket gate 1. This flowchart starts when the user passes the automatic ticket gate 1 by bringing the mobile phone 2 close to the reader / writer 13 shown in FIG. 2 (= by holding the mobile phone 2 over the reader / writer 13). It will start.)

  In step S 1, the control unit 40 of the automatic ticket gate 1 shown in FIG. 1 uses the reader / writer 13 of the contactless IC card 39 of the user's mobile phone 2 based on the automatic ticket gate control program stored in the memory 14. Non-contact communication is performed with the control unit 42. Specifically, when the distance between the reader / writer 13 and the mobile phone 2 is equal to or less than a certain distance (for example, 10 cm or less), the electromagnetic contact from the reader / writer 13 causes the contactless IC card 39 of the mobile phone 2 to be contacted. The power supply is started, the control unit 42 is activated, and the contactless communication between the reader / writer 13 and the contactless IC card 39 is started. The mutual authentication process is a process that is performed first after this communication is started.

  Next, in step S2, the control unit 17 of the automatic ticket gate 1 determines whether or not the non-contact IC card 39 of the user's mobile phone can be authenticated by the authentication process. If the non-contact IC card 39 cannot be authenticated due to unauthorized use or the like, the control unit 17 ends the processing shown in the flowchart of FIG. 5 and authenticates the non-contact IC card 39. If it is possible, the process proceeds to step S3.

  In step S <b> 3, the control unit 17 of the automatic ticket checker 1 communicates with the control unit 42 of the non-contact IC card 39 to transfer the “user identification image” stored in the memory 43 of the non-contact IC card 39. Make a request. When this request is made, the control unit 42 of the non-contact IC card 39 searches the icon image storage area 45 of the memory 43 for “user identification image”. When the “user identification image” is stored in the icon image storage area 45, the control unit 42 of the non-contact IC card 39 reads this “user identification image” and stores it in the reader / writer 13 of the automatic ticket checker 1. If the “user identification image” is not stored in the icon image storage area 45, information indicating that this “user identification image” is not stored is transmitted to the reader / writer 13.

  In step S <b> 4, the control unit 17 of the automatic ticket checker 1 determines whether a “user identification image” exists in the non-contact IC card 39 based on information transmitted from the non-contact IC card 39. That is, when the “user identification image” is received, it can be determined that the “user identification image” exists in the non-contact IC card 39, and thus the process proceeds to step S5. When the information indicating that the “user identification image” is not stored is received, it can be determined that the “user identification image” does not exist in the non-contact IC card 39. In this case, the process proceeds to step S10.

  In step S10, since the “user identification image” cannot be acquired from the non-contact IC card 39, the control unit 17 of the automatic ticket checker 1 is stored in the memory 14 instead of this “user identification image”. “Alternative icon image” is read, and the process proceeds to step S5.

  In step S5, the control unit 17 of the automatic ticket checker 1 settles, for example, a fare, an entrance fee, a transit fare, etc. based on the money information stored in the money information storage area 44 of the memory 43 of the non-contact IC card 39. Processing is performed, and the process proceeds to step S6.

  Next, in step S6, the control unit 17 of the automatic ticket gate 1 replaces the “user identification image” acquired from the non-contact IC card 39 together with the payment information such as the payment amount and balance, or the “user identification image”. The “alternative icon image” read from the memory 14 is displayed on the display unit 15 of the automatic ticket gate 1 shown in FIG.

  FIGS. 6A and 6B show examples of display on the display unit 15. 6A is a display example of the settlement information and “user identification image”, and FIG. 6B is a display example of the settlement information and “alternative icon image”.

  As shown in FIG. 6A, when the “user identification image” can be acquired from the non-contact IC card 39, the control unit 17 selects the “user identification image” selected by the user together with the settlement information such as the balance. Is controlled on the display unit 15.

  On the other hand, when the “user identification image” cannot be acquired from the non-contact IC card 39, the control unit 17 reads out from the memory 14 together with the settlement information such as the balance as shown in FIG. “Alternative icon image” is displayed on the display unit 15.

  As described above, by displaying the “user identification image” selected by the user on the display unit 15 of the automatic ticket checker 1 together with the payment information at the time of automatic ticket check, the display unit 15 is currently displayed to the user. It is possible to clearly recognize that the payment information displayed on the screen is own payment information.

  The “user identification image” displayed together with the settlement information is an image selected by the user, but is not important information such as identification information or personal information uniquely attached to the non-contact IC card 39. There is no worry of being robbed and misused by the three parties. For this reason, a highly safe system can be provided.

[Image display corresponding to balance]
Here, when the control unit 17 of the automatic ticket gate 1 displays the balance of the money information stored in the money information storage area 44 of the non-contact IC card 39 at the time of the settlement process, this is displayed as an image. It is like that.

  Specifically, when the “user identification image” can be acquired from the non-contact IC card 39, the control unit 17 controls the display unit 15 to display the “user identification image” together with the payment information as described above. However, the background of the “user identification image” is displayed in a color corresponding to the balance. FIG. 7 shows a display example of this background.

As can be seen from the example shown in FIG. 7, the control unit 17 determines that the balance of the monetary information stored in the monetary information storage area 44 is
In the case of 0 to 19%, the background color of “red”
If it ’s 20-39%, the background color of “yellow”
In the case of 40-59%, the background color of “green”
In the case of 60-79%, the background color of “light blue”
In the case of 80 to 100%, the background color of “white”
The “user identification image” is displayed and controlled using each.

  More specifically, for example, if the upper limit of the money information that can be stored in the money information storage area 44 of the contactless IC card 39 is “50,000 yen”, the contactless IC card 39 has “50,000 yen”. If the balance is “100%”, the control unit 17 controls the display of the “user identification image” using the “white” background color. Similarly, when the non-contact IC card 39 has a balance of “32,500 yen”, the balance is “65%”, so the control unit 17 uses the “light blue” background color to make a “user identification image”. "Is controlled. Similarly, when the contactless IC card 39 has a balance of “22,500 yen”, since the balance is “45%”, the control unit 17 uses the “green” background color to make a “user identification image”. "Is controlled. Similarly, when the contactless IC card 39 has a balance of “10,000 yen”, since the balance is “20%”, the control unit 17 uses the “yellow” background color to make a “user identification image”. "Is controlled. Similarly, when the contactless IC card 39 has a balance of “5,000 yen”, since the balance is “10%”, the control unit 17 uses the “red” background color to make a “user identification image”. "Is controlled.

  On the other hand, when the “user identification image” cannot be acquired from the non-contact IC card 39, the control unit 17 displays an image of the band-like bar 50 indicating the balance of the monetary information as shown in FIG. A range corresponding to the balance on the bar 50 is displayed in a color corresponding to the balance.

  Specifically, the bar 50 has a total length of 100%. Therefore, when the contactless IC card 39 has a balance of “50,000 yen”, since the balance is “100%”, the control unit 17 displays the entire bar 50 in the above “white”. Similarly, when the contactless IC card 39 has a balance of “32,500 yen”, since the balance is “65%”, the control unit 17 sets the range of 65% of the bar 50 to the “light blue”. indicate. Similarly, when the contactless IC card 39 has a balance of “10,000 yen”, the balance is “20%”, so the control unit 17 sets the range of 20% of the bar 50 in the above “yellow”. indicate.

  Thus, by displaying the background color of the “user identification image” or the “substitute icon image” in a color corresponding to the balance, the user can recognize the balance with information other than numbers. In particular, “yellow” and “red” call attention to humans. Therefore, yellow and red are used to display the background color of “user identification image” and “alternative icon image” to the user. It can prompt the charge of information.

  In addition, when displaying the “user identification image”, the background color is changed according to the balance. However, this is because the color of the “user identification image” itself is changed according to the balance. Good.

  Next, when display control of the “user identification image” or “alternative icon image” is performed on the display unit 15 in this way, the control unit 17 proceeds to step S7 in the flowchart of FIG. It is determined whether or not communication with the non-contact IC card is started. When the start of communication with a new non-contact IC card is detected, the control unit 17 returns the processing to step S1 and performs display control of the above-mentioned “user identification image” or “alternative icon image”. As a result, the “user identification image” or “alternative icon image” stored in the new contactless IC card is controlled to be displayed on the display unit 15 of the automatic ticket checker 1 as described above.

  On the other hand, if the start of communication with the new non-contact IC card is not detected, the control unit 17 displays “user identification image” or “alternative icon image” on the display unit 15 in step S8. It is determined whether a predetermined time has elapsed (timeout). Then, the control unit 17 advances the process to step S9 at the timing when this timeout is detected, and performs non-display control (display clear control) on the “user identification image” or “alternative icon image” displayed on the display unit 15, All the processes shown in the flowchart of FIG.

[Effect of the embodiment]
