Today's mobile handsets have evolved greatly as information and communication technologies have made great strides. Among them, smartphones combine the advantages of mobile phones and personal digital assistants (PDAs). By integrating data communication functions such as a connection, the mobile terminal can be connected directly to the Internet using the wireless Internet, and can be connected to the Internet by various methods using various web browsing programs.

Unlike the existing mobile phones, which are released as a finished product and use only a given function, the greatest feature of a smartphone can be added or removed as many times as the user wants or by creating and applying the desired application program. The advantage is that you can use the interface and features that are right for you. Smartphone application programs range from tens of thousands to hundreds of thousands, depending on the product, and hundreds of new application programs are introduced every day. Simply install the application program, you can easily use the Internet banking, check bus or subway lines and moving points, book a movie or theater, see the simple navigation through the GPS receiver, each press You can also read the latest news at a glance. In addition to watching movies, music, and photos, a variety of application programs allow you to take advantage of unique features not available on a regular phone.

Smartphones also provide a touchscreen user interface. Touch screen in means that when a person's hand or an object touches a character or a specific location on the screen (screen) without using a keyboard, the input data is directly displayed on the screen so that the location can be detected and processed by the stored software. Speak the screen that allows you to receive. The touch screen is a function of attaching a device called a touch panel to the screen of a general monitor. The touch panel causes invisible infrared rays to flow from side to side and up and down to create numerous square grids on the screen. If it touches the grid with other objects, it has a function to determine its position. Therefore, if you touch the character or picture information displayed in advance on the screen equipped with the touch panel by hand, it is very easy to find out what the user has selected according to the position of the touched screen and process the corresponding command by the computer. You can get the information you want. Application program using this has the advantage that the user interface is easy and simple to use the very easy and convenient.

On the other hand, in recent years, the problem of frequency depletion in communication systems using radio waves has emerged, and the harmfulness of various electromagnetic waves to the human body has been highlighted, and the communication technology by the visible light without frequency depletion problems and the human body has been attracting attention. Among them, a method using a white LED (Light Emitting Diode) has been in the spotlight recently. White LEDs consume significantly less power and have a longer lifetime compared to conventional incandescent or fluorescent lamps. Accordingly, research into an illumination light communication system that performs signal transmission by controlling the amount of flashing or light of a white LED used for illumination has been actively conducted. An example of the representative technology may be the one disclosed in registered patent No. 10-0970034 (name: lighting optical communication device, Applicant: Nakagawa Kenkyu Sho, filing date: April 23, 2005). In the case of communication using visible light, it is safe because there is no influence on the human body, and it is possible to use ordinary lighting and power lines, so that the utilization and applicability are very high. Therefore, development of various application technologies is expected.

It is expected that the convergence of mobile terminal technology and visible light communication technology will be able to be utilized in various distributions.

In addition, it is possible to exchange business cards of the same format between mobile terminals running the same electronic business card application program. It is an important element in enhancing the commercial effect of the invention that the electronic business card application provides various and faithful electronic business card frameworks, fonts, pictures, and figures so that various business cards can be produced. have. In addition, the user can also easily modify his or her electronic business card, it is convenient when you need to change the details of the electronic business card by changing the position, address or telephone number. In the case of paper business cards, when there is a need for correction, it is very economical in comparison with the hassle or waste of discarding and remanufacturing existing printed materials.

The electronic business card application program can be implemented by using a software development kit (SDK) that a mobile terminal manufacturer typically publishes to the public for software development of its products. The software development kit is a development tool that is provided free of charge or free to the programmer to make application development simple and easy. Generally, programmers are free of charge for the purpose of adopting their application program interfaces (APIs) when developing solutions, and consist of development tools and libraries, related documents, and development tools. Application program for the implementation of the system according to the present invention can be developed by conventional application programming techniques, so a detailed description of the development is omitted.

4 illustrates an embodiment in which a memo is added to and stored in an electronic business card received at a mobile terminal capable of exchanging an electronic business card using LED visible light communication according to the present invention. In addition to the received business card, the receiving mobile terminal user can additionally write and memorize notes that he wants to record for the memory. Like the phone book storage method on a general mobile terminal, the name can be stored alphabetically or by group. In the embodiment of FIG. 4, the user writes a memo " LED invention application consultation, 2011. 01. 31 " as a memo about the received business card by the user of the mobile terminal receiving the electronic business card, and stores it together with the received electronic business card. The group classification was stored as "patent-related customer". In the case of using the mobile terminal according to the present invention, since the addition and storage of the memo are made as in the above-described embodiment, it is possible to directly take notes by hand by taking a paper business card and efficiently manage the business card information without the hassle of classifying or storing the paper business cards separately.
