  In addition, in order to receive music information stored on a server on the Internet, a connection environment to the server is required. However, there is annoyance that a plurality of operations are necessary. In addition, if there is a malicious attack against a server built on the Internet, the data in the server may be lost. Therefore, it is necessary to take security measures for the server to protect against such an attack. There is a problem that the countermeasure cost increases the usage cost of the user who wants to receive the service.

  In addition, data that has no value due to the doubt that whether the obtained data is genuine or not even for users who received the service due to falsification of data by a malicious person on the server or spoofing of voice data There is also the risk of suffering disadvantages such as paying a price. In providing a service in a state where information purchased by the user is stored in the server, there is a problem that it is costly to take measures against such impersonation.

It can also be provided. At this time, it is also preferable that image printing associated with the image and sound data recorded on the surface of the voice card is performed. This is because, by attaching the image print together with the image / sound data, it is possible to synergistically add rare value as a collection item.

  In this way, in order to change the voice card one after another and enjoy viewing the next image / audio data, more preferably, the rewritable non-volatile memory is connected to the interface and the external playback device for several seconds. In the meantime, the video / audio data that can be stored in a storage capacity that can be transmitted to the external playback device is stored.

  Therefore, it is preferable that the capacity of the image / sound data stored in the rewritable nonvolatile memory is within 9 KB (kilobytes). If the audio data is within 9 KB, the audio for about 4 seconds can be recorded by selecting the storage format. Further, if the audio / video data is within 9 KB, the transmission of the data to the external playback device can be completed within a few seconds. If the transmission speed of data is improved by the advancement of transmission technology in the future, the volume of image / sound data that can be stored in the voice card according to the present invention can be increased. Even with audio recorded in such a capacity, for example, by recording a message of an artist who appeared in a music event, by distributing the voice card according to the present invention as a limited distribution to event participants, A voice card can be used as a privilege for participating in the event.

  Further, according to the present invention, the audio / video data is stored in a voice card in a state independent from a network that can be accessed by an unspecified number of persons such as the Internet after being written into a nonvolatile memory from an external writing device. Therefore, there is no possibility of losing the image / sound data due to a failure of the server as in the case where the image / sound data is stored in a server on a so-called cloud. If the voice card is distributed as an event privilege or the like, the received participant can collect a special message such as the artist as a card. Since the card owner can reproduce the image / sound data with an external reproduction device if the card is present, the card owner can be urged to collect the card. In addition, since the image / sound data is not stored on the network and is stored only in the card owned, the monopoly desire of the card owner can be satisfied.

The voice card 1 includes a card substrate 2, a chip portion 3 built in the card substrate 2, and a non-contact type antenna coil 8a electrically connected to the chip portion 3. The chip unit 3 includes a CPU 4, a ROM 5, a RAM 6, and an EEPROM 7 that is a rewritable nonvolatile memory that are electrically connected to each other so as to be able to exchange signals.

  As shown in FIG. 2, the OS is stored in the ROM 5, and the application P <b> 1 is stored in the processing function storage unit 7 b that is a part of the EEPROM 7. The application P1 operates based on the OS, and transmits the image / audio data 9 stored in the data storage unit 7a of the EEPROM 7 to the external playback device 15 in accordance with a command from the external playback device 15. In the present embodiment, the external playback device 15 is configured to be able to contactlessly transmit and receive a signal composed of a modulated wave to and from the antenna coil 8a using electromagnetic induction or the like.

  With such a configuration, when the antenna coil 8a of the voice card 1 is electrically connected close to the external playback device 15 having the non-contact type connection portion 14, the voice card 1 is continuously connected to the electrical connection. And the image / audio data 9 are transmitted, and the image / audio data 9 automatically reproduced by the external reproduction device 15 can be viewed.

  The audio / video data 9 can be stored in the EEPROM 7 independently from the network. For example, the event organizer stores the voice data (image / sound data 9) of the artist who appeared in the event in the voice card 1 in advance, and sends it to the event participant (user of the voice card 1) at the end of the event. Voice card 1 can be distributed as a souvenir.

  As an example of distribution as a souvenir at the above event, an embodiment until the voice card 1 is produced and used will be described below. Note that Steps 1 to 4 as means relating to the method for producing the voice card 1 and the audio / video data reproduction system until the audio / video data 9 stored in the voice card 1 is transmitted to the external reproduction device 15 and reproduced. Steps 5 to 10 are assigned to the related units, and the reference numbers correspond to the flow shown in FIG.

  When the event organizer prepares the voice card 1, as shown in FIG. 4A, the external writing device 10 includes the card substrate 2 in a state where the image / sound data 9 is not stored in the EEPROM 7. Power is supplied to the card substrate 2 that electrically connects the antenna coil 8a provided on the card substrate 2 and the external writing device 10 by being brought close to the connecting portion 11 (Step 1). With the supplied power, a data receivable signal is transmitted from the card board 2 to the external writing device 10 (Step 2). Subsequently, the image / audio data 9 of the artist recorded in the external writing device 10 that has received the data receivable signal is transmitted from the external writing device 10 to the card substrate 2 (Step 3). The chip unit 3 stores the audio / video data 9 in the data storage unit 7a of the EEPROM 7 to produce the voice card 1 (Step 4).

  The image / sound data 9 stored in the data storage unit 7a is preferably sound data such that, for example, an artist who appeared in an event speaks to the event participants. By repeating the same storing operation of the image / sound data 9 for other voice cards 1, a large number of voice cards 1 storing the image / sound data 9 can be produced and distributed to the event participants as a souvenir.

When the user brings the voice card 1 close to the connection part 14 of the smartphone 15, the user is electrically connected to the antenna coil 8a, and power is supplied to the voice card 1 (Step 5). A data transmission enable signal is transmitted from the voice card 1 to the smartphone 15 by the supplied power (Step 6). The smartphone 15 starts the application 2 simultaneously with transmitting the data receivable signal to the voice card 1 using the received data transmittable signal as a key (Step 7). The voice card 1 uses the reception of the data receivable signal as a key to check whether or not the image / sound data 9 specified by the data receivable signal is present in the data storage unit 7a based on the application P1. Here, the audio / video data 9 is composed of TLV (Tag Length Value) structure data having an extension. The presence or absence of the audio / video data 9 is determined by the CPU 4 and the extension of the audio / video data 9 is the EEPROM 7. This is performed by checking whether or not the data storage unit 7a exists. When the CPU 4 confirms the presence of the extension of the audio / video data 9 and authenticates it, the audio / video data 9 is read out and set in the output buffer in the RAM 6. Further, the CPU 4 sets a read completion status word in the output buffer in the RAM 6, and then outputs the image / audio data 9 and the read completion status word in the output buffer to the external playback device 15. The voice card 1 transmits the image / sound data 9 stored in the data storage unit 7a to the smartphone 15 without going through the network (Step 8). The smartphone 15 receives the image / sound data 9 and stores it in the data storage unit 15b (Step 9). The application P2 identifies the extension of the image / sound data 9 stored in the data storage unit 15b, and reproduces the image / sound data 9 in the case of the designated extension (Step 10).

  Further, an authentication code Q is recorded in the processing function storage unit 7b in the EEPROM 7, and when the voice card 1 is connected to the smartphone 15, the authentication code Q is authenticated by the smartphone 15 so that the voice card 1 is officially registered. It can be proved that it has been manufactured by a simple manufacturer and it can be assured that there is no security problem. The authentication code Q is also composed of TLV structure data, and it is preferable that the smartphone 15 authenticates the presence of the authentication code Q before confirming the presence of the audio / video data 9. Alternatively, the smartphone 15 may instruct the voice card 1 to transmit the image / sound data 9 and activate the application P2. The smartphone 15 is provided with a display screen 15a. When the image / audio data 9 includes image data, the image data is displayed on the display screen 15a when the voice card 1 is held over the smartphone 15. Can also be played back and displayed.
