[0040]
FIG. 3 is a diagram showing a processing flow of the ticket sales system 100.
When the user accesses the ticket sales server 10 using the mobile phone 20 and purchases a concert ticket, the ticket sales server 10 reads the ticket data of the concert ticket purchased by the user from the recording unit 12 and reads it as data A. The data is divided into data B (S31).
[0041]
After the division, the ticket sales server 10 generates barcode data corresponding to the data A, and generates display timing information corresponding to the data B (S32). Then, the generated barcode data and display timing information are transmitted to the mobile phone 20 (S33).
[0042]
On the day of the concert, the bar code image based on the bar code data transmitted by the user when the display unit 24 of the mobile phone 20 is applied to the reading unit 33 of the reading device 30 installed at the reception of the concert venue and the ticket is purchased Is displayed, the barcode image is flashed on the display unit 24 of the mobile phone 20 in accordance with the display timing (S34).

Then, the reading device 30 makes an inquiry to the ticket sales server 10 via the network 40 and confirms that the restored ticket data matches the ticket data actually purchased by the user. If the two match, the user can enter the concert venue.
[0045]
As described above, according to the present embodiment, in addition to the barcode image displayed on the display unit 24 of the mobile phone 20, information is also given to the display timing of the barcode image itself. The ticket data is restored only after
[0046]
Therefore, for example, even if a person who has not purchased a ticket captures a barcode image displayed on the display unit 24 of the mobile phone 20 and presents the captured barcode image to the reading device 30, the barcode is displayed. The data B is not restored only by the code image, and the ticket data is not restored. Therefore, the problem that a person who has not purchased a concert ticket can enter the concert hall can be eliminated, and the safety in the ticket sales system can be ensured.
[0047]
In addition, in a conventional apparatus that transmits data to the reading side by blinking a light emitting element in correspondence with the barcode image without displaying a barcode image on the display unit, the data is transmitted only at the light emission timing of the light emitting element. Not included. However, in this embodiment, the bar code image corresponding to the data A is displayed on the display unit 24 of the mobile phone 20, and the data B can be transmitted by blinking the bar code image. Therefore, more data can be handled than before, and the application range of the system using the barcode image can be expanded.
[0048]
Further, when trying to transmit a large amount of data with the above-mentioned conventional apparatus, it is necessary to blink the light emitting element for a long time, and it takes time to restore the data. However, according to the present embodiment, even if the data is large in capacity, the data can be restored in a short time by making the display timing information itself not so much data.
[0049]
In the present embodiment, the ticket sales server 10 divides the ticket data to generate the barcode image and the display timing information. However, the ticket sales server 10 transmits the ticket data to the mobile phone 20, In the mobile phone 20, the ticket data may be divided to generate a barcode image and display timing information.
[0050]
Further, the barcode image corresponding to the ticket data and the display timing information are generated in advance by another server and recorded in an external database, and the ticket sales server 10 stores the barcode image and the display timing information from the database. May be acquired and transmitted to the mobile phone 20.
[0051]
In the present embodiment, the image data generation unit 14 generates barcode data corresponding to the data A, but this is not limited to barcode data, and is for generating a two-dimensional code image such as a QR code. It may be QR code data. In this case, more data can be transmitted to the mobile phone 20 than the barcode.
[0052]
In this embodiment, the ticket data is divided into two. However, the number of division is not limited to two, and any number may be used as long as it is two or more.
[0053]
In this embodiment, the image data generation unit 14 generates only one piece of barcode data corresponding to the data A. However, a plurality of types of barcode data corresponding to the data A may be generated. This case will be described below.
[0054]
In such a case, the image data generation unit 14 of the ticket sales server 10 generates a plurality of types of barcode data as barcode data corresponding to the data A. The information generation unit 15 of the ticket sales server 10 generates display timing information indicating the display time and display order of each barcode image based on a plurality of types of barcode data.
[0055]
As an example, using a QR code image instead of a barcode image, the image data generation unit 14 generates different n QR codes B1, B2, B3... Bn, and the information generation unit 15 FIG. 4 shows a screen transition state of the display unit 24 of the mobile phone 10 when display timing information is generated with t1, t2,..., T (n−1) as display times of the QR code images.
[0056]
As shown in FIG. 4, when B1 is displayed for t1, the display is changed to B2, and when B2 is displayed for t2, the QR code image is sequentially displayed. In this way, by displaying each of the n QR code images in order, in addition to the data corresponding to each of the n QR code images, the display time pattern can also have data. Therefore, even when the ticket data has a large capacity, it is possible to cope with it.
