INCORPORATION BY REFERENCE TO ANY PRIORITY APPLICATIONS 
       [0001]    Any and all applications for which a foreign or domestic priority claim is identified in the Application Data Sheet as filed with the present application are hereby incorporated by reference under 37 CFR 1.57. 
       BACKGROUND 
       [0002]    Field 
         [0003]    The present disclosure relates to the provision of information to a mobile terminal using near field communication (NFC). 
         [0004]    Description of the Related Art 
         [0005]    Advertising is to provide characteristic information about a specific commodity or service (hereinafter referred to as the “commodity”) to potential consumers and customers in order to promote the sales and distribution of the commodity, and corresponds to one-way communication. 
         [0006]    Advertising media includes a variety of media such as wallpaper, a poster, a signboard, street facilities, a leaflet, radio, a movie, TV, a web banner, a popup advertisement, a magazine, a newspaper, a sticker, and a shopping cart. 
         [0007]    However, such advertising media utilize still images, and therefore the amounts of information to be provided are limited. Although moving image information is utilized recently, it is difficult to repeatedly view and analyze the moving image information which is played. 
         [0008]    Meanwhile, mobile terminals are communication devices which have the advantage of being able to wirelessly connect to a mobile communication system, and wirelessly connect to and communicate with desired counterparties anytime and anywhere while moving. Such mobile terminals are always carried because of the characteristic of communication that communication may be made anytime and anywhere, but have low utilization rate because the period for which they are actually utilized for communication is short. 
         [0009]    Therefore, in order to increase the utilization rate of mobile terminals, additional functionalities, such as E-book, MP3, camera, recorder, scanner, multimedia player, and game machine functionalities, have been added to the mobile terminals. Recently, mobile phones to which tablet computer functionality has been added have been introduced under the name of smartphones. The development of mobile phones to which functionality is added tends to continue. 
         [0010]    Furthermore, short-distance wireless communication functionality, such as Bluetooth, Radio Frequency Identification (RFID), and/or Near Field Communication (NFC), is added to mobile terminals, and therefore the mobile phones can perform tag functionality for managing the history information of commodities, smartcard functionality for performing electronic payment, and/or Peer-to-Peer (P2P) functionality for performing one-to-one communication. 
         [0011]    Conventional advertising media have the disadvantages of instantaneously providing information, and being unable to review the content of an advertisement when a person moves away from a location where the advertisement is made. Conventional moving image-based advertising media also have the disadvantages of being unable to review the content of an advertisement over time, being unable to represent information using a moving image at times, and being unable to review the content of an advertisement when a person moves away from a location where the advertisement is made. 
         [0012]    That is, conventional advertising media is disadvantageous in that it is difficult to review the content of an advertisement when a person moves away from a location where the advertisement is made, a still image advertisement can represent a relatively limited amount of information, and a moving image advertisement cannot represent information which needs to be reviewed and analyzed for a long time, such as a railway schedule. 
         [0013]    Therefore, there is a need for a technology which receives the content of an advertisement from an advertisement medium, records the advertisement in a mobile terminal, and allows a user to repeatedly review and analyze the content of the advertisement when the user moves away from the advertising medium and needs to repeatedly review and analyze the content of the advertisement for a long time. 
         [0014]    Mobile terminals are communication devices which are capable of wirelessly connecting to and communicating with, desired counterparties anytime and anywhere while moving within service areas. Such mobile terminals which are always carried to prepare for communication that may be made anytime and anywhere have low utilization rate because the period for which they are actually utilized for communication is short. The utilization rate of mobile terminals tends to be increased by adding additional functionalities, such as E-book, MP3, camera, recorder, scanner, multimedia player, and game machine functionalities, to the mobile terminals Recently, the utilization rate of mobile terminals is further increased by adding NFC functionality for performing tag functionality, smartcard functionality and P2P functionality. 
         [0015]    Since current mobile terminals tend to be equipped with NFC functionality, a mobile terminal will be described as being an NFC mobile terminal in the following description. 
         [0016]    Furthermore, thanks to the development of communication technology, the development of manufacturing technology and the improvement of mass production technology, the price of NFC mobile terminals and the communication cost have been reduced, and each adult has about one NFC mobile terminal with the advent of the personal communication era. 
         [0017]    Meanwhile, a purchaser who purchases a commodity has prior knowledge about the corresponding commodity and purchase the commodity selected at need, while a vendor generally perform the promotion or advertising of his or her commodity so that the commodity can be selected by many purchasers. 
         [0018]    Purchasers may hesitate or may not immediately make up his or her mind when there is a plurality of commodities of the same type or a similar type. 
         [0019]    A barcode or a Quick Response (QR) code indicative of information, such as the name, manufacturer, price, release date, expiration date, serial number and location of a commodity, is represented on a commodity. 
         [0020]    Conventionally, information about a commodity, such as the advertisement, use and functionality of the commodity, is provided using advertising leaflets, specifications and promotion materials in the form of a discontinuous and concentrated event. 
         [0021]    Therefore, it is difficult for a user or a purchaser to obtain the advertisement information of a commodity in such an event where the commodity is advertized. Furthermore, even when a person participates in such an event and becomes aware of the advertisement information of a commodity, the person forgets the information over time, and therefore the effect of such advertising is very low. 
         [0022]    Furthermore, since specific information about a commodity, such as the advertisement information, expiration date and use of the commodity, is frequently changed and updated, it is difficult to provide accurate information to purchasers. 
         [0023]    Therefore, there is a need for the development of a technology which is capable of providing information about each commodity (hereinafter referred to as “commodity information”) including, for example, the advertisement information, promotion information, name, release date, expiration date, manufacturer, serial number and price information of the commodity using a QR code or a barcode (hereinafter referred to as an “optical code”) which is represented on the commodity. 
         [0024]    In particular, there is a need for the development of a technology which is capable of providing commodity information, included in an optical code represented on each commodity, to an NFC mobile terminal which is being carried by an individual person using NFC communication, so that a purchaser can rapidly check accurate commodity information. 
         [0025]    The foregoing information included in this section is only to provide background of the invention and does not constitute an admission of prior art.

     DESCRIPTION OF EMBODIMENTS 
       [0099]    Reference now should be made to the drawings, in which the same reference numerals are used throughout the different drawings to designate the same or similar components. 
         [0100]    The present invention may be modified in a variety of ways, and may include a variety of embodiments. Specific embodiments will be illustrated in the accompanying drawings and described in detail below. However, it should be appreciated that this is not intended to limit the present invention to the specific embodiments, but the present invention includes all modifications, equivalents and alternatives which fall within the spirit and technical range of the present invention. Descriptions of well-known functions and constructions which have been deemed to make the gist of the present invention unnecessarily vague will be omitted below. 
         [0101]    In the present invention, an advertisement medium is described as being a multimedia signal including an image(s), a character(s), and a sound signal, and an operation applet is described as being an application program which performs control for a selected application. 
         [0102]    That is, a mobile terminal includes a plurality of application programs, each of the application programs is referred to as an operation applet, and the application programs are identified by respective pieces of applet identifier (AID) information. Furthermore, the same applets may be assigned different pieces of applet identifier (AID) information when their versions or manufacturers are different. 
         [0103]    When a mobile terminal communicates with a counterparty mobile terminal, or a mobile terminal operates a specific application program in conjunction with a counterparty mobile terminal in a one-to-one correspondence, they should include and operate the same applets having the same applet identifier (AID) information. 
         [0104]    Communication mode in which signals are transmitted and received in NFC communication includes card mode and read mode. The card mode is described as being mode in which recorded information signals are provided to a counterparty, and the read mode is described as being mode in which the recorded information signals of a counterparty are read. 
         [0105]    A barcode is a linear one-dimensional (1D) code which is formed by combining a plurality of white and black bars having different widths and can be easily read by a computer, and is widely used to represent the unique number and/or price information of a commodity. 
         [0106]    A Quick Response (QR) code is a matrix-type two-dimensional (2D) code which is formed by arranging small square dots equally in lateral and vertical directions and can be read by a computer. A QR code may have on its each side dots the number of which ranges from 21 to 177, can record a maximum of 23,648 bits, can be recovered thanks to its supplementary property when part of its data is damaged, and can be recognized or read in all directions of 360 degrees. 
         [0107]    Tagging or tag is described as being the state of being close to a counterparty without electrically direct contact. 
         [0108]      FIG. 1  is a functional block diagram illustrating the configuration of an advertisement information provision system  10000  according to an embodiment of the present invention. 
         [0109]    Referring to  FIG. 1 , the advertisement information provision system  10000  according to the embodiment of the present invention will now be described in detail. The advertisement information provision system  10000  includes a mobile terminal  11000 , a panel unit  12000 , and an advertisement management server  13000 . 
         [0110]    The mobile terminal  11000  is a mobile communication terminal capable of wirelessly accessing a mobile communication system and immediately communicating with a desired counterparty ubiquitously, and records a plurality of operation applets, identified by applet identifier (AID) information, in an assigned memory area. 
         [0111]    The mobile terminal  11000  operates in card mode in its initial stage, tags the panel unit  12000 , searches for a record of designated applet identifier (AID) information from the plurality of recorded applet identifier (AID) information in response to a request from the panel unit  12000 , and notifies the panel unit  12000  of search results once the record of designated AID information has been retrieved. 
         [0112]    In the following description of the present invention, the mobile terminal  11000  will be described as recording a designated operation, applet, and an applet corresponding to applet identifier (AID) information requested by the panel unit  12000  will be described as an operation applet capable of receiving advertisement media. 
         [0113]    The fact that the mobile terminal  11000  has retrieved AID information designed by the panel unit  12000  means that the mobile terminal  11000  and the panel unit  12000  can activate the same operation applet and then perform data communication without suffering from errors. 
         [0114]    The mobile terminal  11000  wakes up an operation applet corresponding to the designated applet identifier (AID) information, that is, an operation applet capable of receiving advertisements, so that it can enter an active state in response to a mode-switching request from the panel unit  12000 , switches the operating mode from the initial card mode to read mode, and notifies the panel unit  12000  of the results of the wake-up and the mode-switching. 
         [0115]    In this case, the mobile terminal  11000  additionally transmits a mode-switching request signal, requesting switching to card mode, to the panel unit  12000 . 
         [0116]    Furthermore, the mobile terminal  11000  receives advertisement media data from the panel unit  12000  while staying in a tagged state, and notifies the panel unit  12000  of the completion of the reception if the reception is completed without undergoing errors. 
         [0117]    The panel unit  12000  includes a panel operation unit  12100  and an advertisement output unit  12200 . The panel operation unit  12100  includes a process unit  12110 , a tag applet unit  12120 , an NFC controller unit  12130 , and an advertisement signal processing unit  12140 . The advertisement output unit  12200  includes an output unit  12220  and an antenna unit  12240 . 
         [0118]    When a mobile terminal  11000  tags the panel unit  12000  in initial read mode in which the information of a counterparty is read, the panel unit  12000  request a search for corresponding applet identifier (AID) information to check whether an operation applet for receiving an advertisement has been recorded in the mobile terminal  11000 , and requests that the mobile terminal  11000  switches to read mode when receiving search results. 
         [0119]    The process unit  12110  which constitutes a part of the panel operation unit  12100  of the panel unit  12000  requests a tag applet, including advertisement media, from the connected advertisement management server  13000 , and receives the tag applet. 
         [0120]    In the following description, a tag applet will be described as being matched to a corresponding advertising medium, and advertisement media will be described as multimedia including a still image(s), a moving image(s), a character(s), a sound(s), and/or an image(s), but not limited thereto. 
         [0121]    The process unit  12110  records the received advertisement media and tag applet in respective assigned areas of the tag applet unit  12120 . There are a variety of types of tag applets depending on the contents and purposes of advertisements, and the tag applet unit  12120  records tag applets which are matched to a plurality of various advertisement, media. 
         [0122]    Since the process unit  12110  performs control so that any advertisement media selected from among those recorded in the tag applet unit  12120  is applied and output to the advertisement signal processing unit  12140 , the advertisement signal processing unit  12140  classifies the applied advertisement media as a multimedia signal including an image(s), a sound(s), or a character(s) and outputs the multimedia signal to the output unit  12220  of the advertisement output unit  12200 . 
         [0123]    The output unit  12220  includes a video unit for outputting video signals and character signals and an audio unit for outputting sound signals. 
         [0124]    Meanwhile, the process unit  12110  performs control so that a tag applet matched to an advertisement medium output by the advertisement signal processing unit  12140  can be read from the tag applet unit  12120 , and be applied to and output by the NFC controller unit  12130 . 
         [0125]    Since the NFC controller unit  12130  outputs the applied tag applet to the antenna unit  12240  of the advertisement output unit  12200 , the antenna unit  12240  can radiate a signal which resonates with, for example, a radio frequency in the 13.56 MHz band. 
         [0126]    In an embodiment, when the mobile terminal  11000  tags the antenna unit  12240 , the antenna unit  12240  detects the tagging of the mobile terminal  11000  and provides notification to the NFC controller unit  12130  of the panel operation unit  12100 , and the NFC controller unit  12130  requests a search for applet identifier (AID) information to check if the AID information of the operation applet which will receive an advertisement has been recorded in the mobile terminal and outputs a signal requesting the mode-switching of the mobile terminal  11000  if the corresponding AID information has been retrieved and returned. 
         [0127]    The NFC controller unit  12130  checks if the mobile terminal  11000  has switched to read mode in response to a mode-switching request, and performs switching to card mode which provides recorded data when a signal requesting mode-switching is received from the mobile terminal  11000 . 
         [0128]    When the switching to card mode has been performed, the NFC controller unit  12130  searches for advertisement media, being currently output by the output unit  12220 , from the tag applet unit  12120  and then outputs the advertisement media to the antenna unit  12240  under the control of the process unit  12110 , and the antenna unit radiates data to the mobile terminal  11000 . 
         [0129]    Here, the output unit  12220  and the antenna unit  12240  may be paired with each other, and may output and radiate advertisement media of the same content under the control and monitoring of the process unit  12110 . 
         [0130]    Therefore, when the output unit  12220  and the antenna unit  12240  form a single pair in accordance with the embodiment, a plurality of advertisement media is output at different times. When output units  12220  and antenna units  12240  form a plurality of pairs in accordance with another embodiment, a plurality of advertisement media can be simultaneously output and provided via respective paths. The different configurations according to the embodiment of the panel unit  12000  will be described in detail below with reference to the accompanying drawing. 
         [0131]    The advertisement management server  13000  may create and provide a plurality of advertisement media in, real time or search for and provide one or more of a plurality of recorded advertisement media in response to a request from the panel unit  12000 . The advertisement management server  13000  includes a control unit  13100 , an advertisement radiation DB unit  13200 , and a tag applet DB unit  13300 . The configuration of the advertisement management server  13000  will be described in detail below with reference to the accompanying drawings. 
         [0132]      FIG. 2  is a detailed functional block diagram illustrating the configuration of an advertisement management server  13000  according to an embodiment of the present invention. 
         [0133]    Referring to  FIG. 2 , the advertisement management server  13000  will now be described in detail. The control unit  13100  controls and monitors the advertisement radiation DB unit  13200  and the tag applet DB unit  13300  so that created or retrieved advertisement media can be delivered in real time when a signal requesting the provision of a tag applet including selected advertisement media is received from the panel unit  12000 . 
         [0134]    When, the advertisement radiation DB unit  13200  is controlled by the control unit  13100  so that the advertisement radiation DB unit  13200  generates advertisement media in real time, the advertisement radiation DB unit  13200  may receive a multimedia signal from the outside and then create a new advertisement medium in real time, may create a new advertisement medium using a multimedia signal received from the outside and an advertisement medium retrieved in real time, or may create a new advertisement medium using a plurality of retrieved advertisement media in real time. 
         [0135]    The advertisement radiation DB unit  13200  may record the advertisement medium, created in real time, in its own assigned area, and search for and reuse it later. 
         [0136]    Furthermore, under the control of the control unit  13100 , the tag applet DB unit  13300  creates a tag applet, which matches the advertisement medium created by the advertisement radiation DB unit  13200 , and at the same time transmits it to the advertisement radiation DB unit  13200  and records it in its own assigned area. 
         [0137]    Here, the tag applet is described as being an application program which enables a counterparty to receive an advertisement medium which is created and radiated using an NFC wireless method. 
         [0138]    The control unit  13100  controls the advertisement radiation DB unit  13200 , so that a created or retrieved advertisement medium is read. The control unit  13100  controls the tag applet DB unit  13300  so that a tag applet which is matched to the advertisement medium is newly created or a corresponding retrieved tag applet is applied to the advertisement radiation DB unit  13200 . 
         [0139]    That is, according to an embodiment of the present invention, when the advertisement radiation DB unit  13200  creates a new advertisement medium, a new tag created by the tag applet DB unit  13300  is used. In contrast, when the advertisement radiation DB unit  13200  retrieves an existing recorded advertisement medium, an existing tag applet recorded in the tag applet DB unit  13300  is retrieved and used. 
         [0140]    The advertisement radiation DB unit  13200  completes provision by transmitting the created and retrieved advertisement medium and the corresponding tag applet to the panel unit  12000  in real time under the control and monitoring of the control unit  13100 . 
         [0141]      FIG. 3  is a detailed functional block diagram illustrating the configuration of a panel unit  12000  according to a first embodiment of the present invention. 
         [0142]    Referring to  FIG. 3 , the panel unit  12000  will now be described in detail. The panel unit  12000  according to the first embodiment includes a panel operation unit  12100 , and an advertisement output unit  12200 . 
         [0143]    The panel operation unit  12100  includes a process unit  12110 , a tag applet unit  12120 , an NFC controller unit  12130 , and an advertisement signal processing unit  12140 . The advertisement output unit  12200  includes an output unit  12220 , and an antenna unit  12240 . 
         [0144]    Here, the output unit  12220  and antenna unit  12240  of the advertisement output unit  12200  form a pair so that they output and radiate signals of the same content while operating in conjunction with each other. 
         [0145]    That is, the output unit  12220  and the antenna unit  12240  which constitute the advertisement output unit  12200  output or radiate an advertisement medium of the same content, form a pair, and have corresponding paths over which data of the same content is transmitted. 
         [0146]    The process unit  12110  which constitutes a part of the panel operation unit  12100  receives a corresponding tag applet matched to the advertisement media from the advertisement management server  13000 , records it in the assigned area of the tag applet unit  12120 , and applies it to the NFC controller unit  12130  and the advertisement signal processing unit  12140 . 
         [0147]    The NFC controller unit  12130  outputs a designated advertisement medium to the antenna unit  12240  via a corresponding path in the form of data under the control and monitoring of the process unit  12110 . 
         [0148]    Furthermore, the advertisement signal processing unit  12140  outputs a designated advertisement medium to the output unit  12220  via a corresponding path in the form of a multimedia signal under the control and monitoring of the process unit  12110 . 
         [0149]    The advertisement output unit  12200  outputs one or more designated advertisement media under the control of the panel operation unit  12100 . It is apparent that when a plurality of advertisements are output, different advertisement media are output and radiated at different times. 
         [0150]    In the configuration according to the first embodiment of the present invention, a selected advertisement medium is output through the output unit  12220  in the form of a multimedia signal, and, when the mobile terminal  11000  tags the antenna unit  12240 , an advertisement medium of content which is the same as the content of the advertisement medium output through the output unit  12220  is provided in the form of data. 
         [0151]    Accordingly, the mobile terminal  11000  receives the advertisement medium, which output through the output unit  12220 , in the form of data by tagging the antenna unit  12240  and then records it in its own memory area, so that there are the advantages of repeatedly viewing and/or listening to the corresponding advertisement medium ubiquitously and analyzing it over time. 
         [0152]    In particular, there is the advantage of reviewing or comparing and analyzing the content of the advertisement media (or media) when the content of an advertisement is summarized or the time tables of a movie or the prices of a product are compared with each other. 
         [0153]      FIG. 4  is a detailed functional block diagram illustrating the configuration of a panel unit  12000  according to a second embodiment of the present invention. 
         [0154]    Referring to  FIG. 4 , the panel unit  12000  will now be described in detail. The panel unit  12000  according to the second embodiment includes a panel operation unit  12100 , and an advertisement output unit  12200 . 
         [0155]    The panel operation unit  12100  includes a process unit  12110 , a tag applet unit  12120 , an NFC controller unit  12130 , and an advertisement signal processing unit  12140 . The advertisement output unit  12200  includes an output unit  12220  including first to n-th output units  12221 ,  12222 , . . . , and  12223 , and an antenna unit  12240  including first to n-th antenna units  12241 ,  12242 , . . . , and  12243 . 
         [0156]    In an embodiment, the first output unit  12221  and the first antenna unit  12241  form a pair, the second output unit  12222  and the second antenna unit  12242  form a pair, . . . , and the n-th output unit  12223  and the n-th antenna unit  12243  form a pair. 
         [0157]    The output unit  12220  and the antenna unit  12240  paired as described above output an advertisement medium of the same content via a corresponding path of each pair. 
         [0158]    Since the process unit  12110  and tag applet unit  12120  of the panel operation unit  12100  are the same as those of the first embodiment, a description thereof is omitted to avoid a redundant description. 
         [0159]    The NFC controller unit  12130  may separately manage the paths of the plurality of antenna units  12241 ,  12242 , . . . , and  12243  which constitute the antenna unit  12240 , and performs control so that the plurality of antenna units  12241 ,  12242 , . . . , and  12243  output and radiate corresponding tag applets and so that when it is determined that the mobile terminal  11000  has performed tagging or tag reading on one of the antenna units  12241 ,  12242 , . . . , and  12243 , a matched corresponding advertisement medium is output in the form of data, thus being radiated via the corresponding antenna unit  12241 ,  12242 , . . . , or  12243 . 
         [0160]    Furthermore, the advertisement signal processing unit  12140  may separately manage the paths of the plurality of output units  12221 ,  12222 , . . . , and  12223  which constitute the output unit  12220 , and performs control so that a corresponding advertisement medium is output in the form of a multimedia signal. 
         [0161]    Here, the NFC controller unit  12130  and the advertisement signal processing unit  12140  are synchronized with each other and output information corresponding to an advertisement medium of the same content over a path to which a pair of the synchronized output unit  12220  and antenna unit  12240  of the advertisement output unit  12200  are connected. 
         [0162]    The configuration of the embodiment of the present invention has the advantage of selectively or simultaneously outputting one or more advertisements selected from among a plurality of a variety of advertisements using a single advertisement medium. 
         [0163]      FIG. 5  is a flowchart illustrating a process of operating the advertisement information provision system according to an embodiment of the present invention. 
         [0164]    Referring to  FIG. 5 , the process of operating the advertisement information provision system according to the embodiment of the present invention will now be described in detail. The mobile terminal operates in card mode in its initial stage, the panel unit operates in read mode in its initial stage, and the panel unit outputs an advertisement medium in the form of a multimedia signal and also outputs a tag applet matched to the advertisement medium in the form of data in accordance with the first or second embodiment. 
         [0165]    Card mode is described as being the state of providing recorded information to a counterparty, while read mode is described as being the state of reading the information of a counterparty. 
         [0166]    When a user desires to download the content of an advertisement medium currently being advertised in order to repeatedly play back or analyze the content of the advertisement medium output by an output unit of the panel unit, the mobile terminal tags a corresponding antenna unit which is paired with the output unit at step S 2010 . 
         [0167]    The panel unit issues a request to the mobile terminal that it search for corresponding applet identifier (AID) and make a response at step S 2020  in order to check whether a corresponding operation applet capable of receiving the advertisement medium has been recorded in the mobile terminal. 
         [0168]    The mobile terminal searches for the corresponding AID information and then returns information about retrieved corresponding ID in response to the request from the panel unit at step S 2030 . In this case, the panel unit requests mode-switching from the mobile terminal at step S 2040 . The request for mode-switching is to request that the mobile terminal switches to read mode and operates in read mode. 
         [0169]    When the mobile terminal receives a mode-switching request signal from the panel unit, the mobile terminal wakes up a corresponding operation applet so that it is activated to receive the advertisement medium at step S 2050 , and is automatically switched from the current card mode to read mode at step S 2060 . 
         [0170]    That is, the mobile terminal automatically switches from current card mode to read mode, and at the same time notifies the panel unit of the mode-switching and requests that the panel unit automatically switch its operating mode from read mode to card mode at step S 2070 . 
         [0171]    The panel unit switches the current operating mode of the mobile terminal from read mode back to card mode in response to the response and the request at step S 2080 , and returns the results of the automatic mode-switching to the card mode to the mobile terminal at step S 2090 . 
         [0172]    Furthermore, the panel unit requests to the advertisement management server a tag applet capable of downloading an advertisement medium matched to the tagged antenna unit and the corresponding advertisement medium from the advertisement management server at step S 2100 , and the advertisement management server creates or searches for the requested advertisement medium and the matched tag applet in real time at step S 2110 , and transmits and provides the advertisement medium retrieved or created in real time to the panel unit at step S 2120 . 
         [0173]    The panel unit checks the advertisement medium and the matched tag applet for errors while receiving the advertisement medium and the matched tag applet provided by the advertisement management server, records the received advertisement medium and matched tag applet in the assigned memory area of the tag applet unit if they have been received without any error, and monitors whether the mobile terminal performs tagging for reading at step S 2130 . 
         [0174]    In this case, if the corresponding advertisement medium and matched tag applet have been already recorded in the memory area of the tag applet unit, the panel unit may not request transmission from the advertisement management server. 
         [0175]    When the panel determines that the mobile terminal is in a tag reading state so that it can read the advertisement medium in the form of data at step S 2140 , the panel unit transmits the matched tag applet and the corresponding advertisement medium to the mobile terminal via the tagged corresponding antenna unit in the form of data at step S 2150 . 
         [0176]    The mobile terminal checks whether the data of the advertisement medium has been received without any error using the received tag applet at step S 2160 , and, if the overall data of the advertisement medium has been received without any error, the mobile terminal returns a reception completion signal to the panel unit at step S 2170 . 
         [0177]      FIG. 6  is a functional block diagram illustrating the configuration of an advertisement information provision system  10000  according to another embodiment of the present invention. 
         [0178]    Referring to  FIG. 6 , the advertisement information provision system  10000  will now be described in detail. The advertisement information provision system  10000  includes a mobile terminal  11000 , a panel unit  12000 , and an advertisement management server  13000 . 
         [0179]    Since the advertisement information provision system illustrated in  FIG. 6  is similar to that illustrated in  FIG. 1 , descriptions of differences therebetween will now be mainly provided. 
         [0180]    The mobile terminal  11000  has the functionality of immediately and wirelessly connecting to and communicating with a desired counterparty ubiquitously while moving, like the mobile terminal illustrated in  FIG. 1 . The mobile terminal  11000  further includes a scanner unit  1110  which is capable of reading a barcode and a QR code by scanning them. 
         [0181]    Here, the barcode and the QR code are described as being output by the panel unit  12000 . The scanner unit  1110  may include one or more which are selected from among a configuration for optically scanning a barcode and a QR code and a configuration for wireless receiving them. 
         [0182]    The panel unit  12000  includes a panel operation unit  12100  and an advertisement output unit  12200 , like the panel unit illustrated in  FIG. 1 .

The NFC controller unit  12130  applies the QR code or barcode to the code radiation unit  12260  of the advertisement output unit  12200 , so that the QR code or barcode can be transmitted. 
         [0185]    Here, according to an embodiment of the present invention, the code radiation unit  12260  may include a display unit which visually displays a QR code or barcode. The code radiation unit may perform wireless output. 
         [0186]    The configuration of the panel unit  12000  will be described in detail later with reference to the accompanying drawing and an embodiment. 
         [0187]    The advertisement management server  13000  includes a control unit  13100 , an advertisement radiation DB unit  13200 , a tag applet DB unit  13300 , like the advertisement management server illustrated in  FIG. 1 , and further includes an advertisement tag applet unit  13400 , a QR code tag applet unit  13500 , and a barcode tag applet unit  13600 . 
         [0188]    The advertisement management server  13000  will be described in detail below with reference to the accompanying drawing. 
         [0189]      FIG. 7  is a detailed functional block diagram illustrating the configuration of an advertisement management server  13000  according to another embodiment of the present invention. 
         [0190]    Referring to  FIG. 7 , the advertisement management server  13000  will now be described in detail. The advertisement management server  13000  includes a control unit  13100 , an advertisement radiation DB unit  13200 , a tag applet DB unit  13300 , an advertisement tag applet unit  13400 , a QR code tag applet unit  13500 , and a barcode tag applet unit  13600 . 
         [0191]    Since the configuration and operation of the control unit  13100  and the advertisement radiation DB unit  13200  are the same as those illustrated in  FIG. 2 , redundant descriptions thereof will not be given here. 
         [0192]    The tag applet DB unit  13300  records all tag applets, being created or created by the advertisement management server  13000 , under the control and monitoring of the control unit  13100 . A tag applet selected by searching may be reused. 
         [0193]    The advertisement tag applet unit  13400  creates a tag applet which matches the advertisement media created by the advertisement radiation DB unit  13200 , and then transmits the tag applet to the tag applet DB unit  13300 , under the control of the control unit  13100 . 
         [0194]    Here, the tag applet is described as being an application program which enables a counterparty to receive an advertisement media which is created and then transmitted, via an NFC wireless connection. 
         [0195]    The QR code tag applet unit  13500  creates a QR code tag applet under the control of the control unit  13100 , and the barcode tag applet unit  13600  creates a barcode tag applet under the control of the control unit. 
         [0196]    The QR code tag applet and the barcode tag applet created by the QR code tag applet unit  13500  and the barcode tag applet unit  13600 , respectively, are applied to the advertisement radiation DB unit  13200 , and then transmitted to the panel unit  12000 , under the control of the control unit  13100 . 
         [0197]      FIG. 8  is a detailed functional block diagram illustrating the configuration of a panel unit  12000  according to a third embodiment of the present invention. 
         [0198]    Referring to  FIG. 8 , the panel unit  12000  according to the third embodiment of the present invention will now be described in detail. The panel unit  12000  according to the third embodiment includes a panel operation unit  12100 , and an advertisement output unit  12200 , like that according to the first embodiment. 
         [0199]    The panel operation unit  12100  includes a process unit  12110 , a tag applet unit  12120 , an NFC controller unit  12130 , an advertisement signal processing unit  12140 , a QR code analysis unit  12150 , and a barcode analysis unit  12160 . The advertisement output unit  12200  includes an output unit  12220 , an antenna unit  12240 , and a code radiation unit  12260 . 
         [0200]    Here, since the process unit  12110 , tag applet unit  12120 , NFC controller unit  12130  and advertisement signal processing unit  12140  of the panel operation unit  12100  and the output unit  12220  and antenna unit  12240  of the advertisement output unit  12200  are the same as those of the first embodiment, redundant descriptions thereof will be omitted here. 
         [0201]    The QR code analysis unit  12150  analyzes a received QR code or outputs a created QR code to the advertisement output unit  12200  via the NFC controller unit  12130  under the control and monitoring of the process unit  12110 . 
         [0202]    The barcode analysis unit  12160  analyzes a received barcode or outputs a created barcode to the advertisement output unit  12200  via the NFC controller unit  12130  under the control, and monitoring of the process unit  12110 . 
         [0203]    The code radiation unit  12260  radiates an applied QR code or barcode via the NFC controller unit  12130 . 
         [0204]    The configuration according to the embodiment of the present invention has the advantage of outputting QR code or barcode while outputting a single advertisement medium or outputting a plurality of advertisement media at different times. 
         [0205]      FIG. 9  is a detailed functional block diagram illustrating the configuration of a panel unit  12000  according to a fourth embodiment of the present invention. 
         [0206]    Referring to  FIG. 9 , the panel unit  12000  according to the fourth embodiment of the present invention  12000  will now be described in detail. The panel unit  12000  according to the fourth embodiment includes a panel operation unit  12100  and an advertisement output unit  12200 , like that of the second embodiment. 
         [0207]    Since the process unit  12110 , tag applet unit  12120 , NFC controller unit  12130  and advertisement signal processing unit  12140  of the panel operation unit  12100  have same configurations and operations as those of the second embodiment and the QR code analysis unit  12150  and barcode analysis unit  12160  of the panel operation unit  12100  have same configurations and operations as those of the third embodiment, redundant descriptions thereof will not be given here. 
         [0208]    Furthermore, since the output unit  12220  and antenna unit  12240  of the advertisement transmission unit  12200  have the same configurations and operations as those of the second embodiment and the code radiation unit  12260  of the advertisement transmission unit  12200  have the same configurations and operations as those of the third embodiment, redundant descriptions thereof will not be given here. 
         [0209]    A barcode is a linear one-dimensional (1D) code which is formed by combining a plurality of white and black bars having different widths and can be easily read by a computer, and is widely used to record information about the name, management number, release date, expiration date and price of a commodity. 
         [0210]    A QR (Quick Response) code is a matrix-type two-dimensional (2D) code which is formed by arranging small square dots equally in lateral and vertical directions and can be read by a computer. A QR code may have on its each side dots the number of which ranges from 21 to 177, can record a maximum of 23,648 bits, can be recovered thanks to its supplementary property when part of its data is damaged, and can be recognized or read in all directions of 360 degrees. That is, QR codes can record larger amounts of information than barcodes, and may include link information. 
         [0211]    The current QR code is a 2D code technology develop and released by a company, and new-types of 2D code technologies may be developed by other companies in other forms. 
         [0212]    The tagging or tag, is described as being the state of recognizing the electrical data of a counterparty near the counterparty without electrically direct contact. 
         [0213]    The NFC mobile terminal includes a plurality of application programs. Each of the application programs is referred to an applet. The application programs are identified by respective pieces of applet identifier (AID). Furthermore, the same applets may be assigned different pieces of applet identifier (AID) when their versions or manufacturers are different. 
         [0214]    When a specific device including the NFC mobile terminal communicates with or operates in conjunction with a counterparty device in a one-to-one correspondence, they should include and operate the same applets having the same AID information. 
         [0215]    Furthermore, the same applets having the same AID information may be divided into a main applet and a sub-applet. In the present invention, the main applet is referred to as a driving applet, and the sub-applet is referred to as a tag applet. 
         [0216]    Therefore, NFC mobile terminals which operate with each other should include and operate the same applets, and therefore should have the same AID information. 
         [0217]    Communication mode in which signals are transmitted and received using an NFC method includes card mode and read mode. The card mode is described as being mode in, which recorded information signals are provided to a counterparty, and the read mode is described as being mode in which information signals recorded in a counterparty are read. 
         [0218]    In the present invention, content is described as being digital data information including one or more of media such as a character(s), a still image(s), a moving image(s), image(s), and sound(s), and multimedia is described as being an output including one or more of a sound(s), a moving image(s), a still image(s), and a character(s). 
         [0219]    Furthermore, commodity information is described as including the advertisement information, characteristic information, expiration date, use, price, etc. of a corresponding commodity. 
         [0220]      FIG. 10  is a functional block diagram illustrating the configuration of a commodity information provision system  1000  according to a fifth embodiment of the present invention. 
         [0221]    Referring to  FIG. 10 , the commodity information provision system  1000  according to the fifth embodiment of the present invention will now be described in detail. The commodity information provision system  1000  includes an apparatus unit  1090  including a panel unit  1100  and an operation unit  1200  and a server unit  1300 . 
         [0222]    The apparatus unit  1090  includes the panel unit  1100  and the operation unit  1200 , and may be one selected from among a NFC reader and a mobile terminal, which is the same throughout the following description. 
         [0223]    The panel unit  1100  may include a camera unit  1110 , an output unit  1120 , and an NFC antenna unit  1130 . The operation unit  1200  may include a QR analysis unit  1210 , a process unit  1220 , an NFC controller unit  1230 , and a tag applet recording unit  1240 . The server unit  1300  may include a tag applet issuance unit  1310 . 
         [0224]    The camera unit  1110  includes a camera which captures an image of an optical code (including, for example, a QR code) which is represented on a commodity  1400 . 
         [0225]    The output unit  1120  outputs and displays an image, captured by the camera unit  1110 , so that the image can be visually checked or viewed. Here, according to an embodiment of the present invention, it may be checked whether such an optical code has been accurately scanned or captured by the camera unit  1110 , using the output unit  2120 . 
         [0226]    According to an embodiment of the present invention, the NFC antenna unit  1130  is configured to be turned to a wireless frequency in the 13.56 MHz band, and wirelessly transmits and receives NFC signals. 
         [0227]    The QR analysis unit  1210  receives the optical code captured by the camera unit  1110 , recognizes and analyzes a QR code, and converts the QR code into commodity data. 
         [0228]    The commodity data recognized, analyzed and obtained using the QR code includes a variety of information such as the name, manufacturer, management number, release date, expiration date, price, features, use and advertisement information of a commodity  1400 , and may further include link information. 
         [0229]    The process unit  1220  monitors and controls the functional units of the panel unit  1100  and the operation unit  1200 , receives the commodity data from the QR analysis unit  1210 , and outputs the commodity data to the server unit  1300 . 
         [0230]    Furthermore, the process unit  1220  receives a tag applet provided by the server unit  1300 , and applies the tag applet to the NFC controller unit  1230 . 
         [0231]    The NFC controller unit  1230  operates in NFC read mode in its initial stage, and records information about the tag applet, provided by the process unit  1220 , in the assigned area of the tag applet recording unit  1240 . 
         [0232]    The NFC controller unit  1230  monitors the NFC antenna unit  1130  of the panel unit  1100 , and detects the tagging of the NFC mobile terminal  1500 . 
         [0233]    When the NFC controller unit  1230  detects the tagging of the NFC mobile terminal  1500 , it requests applet identifier (AID), requests that mode-switching is automatically performed, and receives a response signal indicative of corresponding results. 
         [0234]    Once the NFC controller unit  1230  has received the response signal, it is automatically switched from read mode to card mode, and outputs a tag applet recorded in the tag applet recording unit  1240 , thereby transmitting the tag applet to the NFC mobile terminal  1500  via the NFC antenna unit  1130 . 
         [0235]    In this case, when the NFC controller unit  1230  receives a response indicative of the normal reception of the tag applet without transmission error from the NFC mobile terminal  1500 , it deletes the corresponding tag applet recorded in the tag applet recording unit  1240 . That is, the information of the tag applet is allowed to be provided only once. 
         [0236]    The server unit  1300  includes the tag applet issuance unit  1310 , receives the commodity data provided by the operation unit  1200 , converts the commodity data into a tag applet using the tag applet issuance unit  1310 , and transmits the tag applet to the operation unit  1200 . 
         [0237]    The commodity  1400  may be any type of commodity, and an optical code may be represented, for example, on the surface of the commodity  1400 . 
         [0238]    The NFC mobile terminal  1500  connects to the mobile communication system, and communicates with a desired counterparty via a wireless connection. The NFC mobile terminal  1500  may include an NFC communication function and then perform NFC communications. Alternatively, the NFC mobile terminal  1500  may include only an NFC communication function. 
         [0239]    The NFC mobile terminal  1500  includes a plurality of application applets including a driving applet, and these applets are identified by respective pieces of AID information. The driving applet is described as being an application program which transmits and receives commodity information. 
         [0240]    The NFC mobile terminal  1500  operates in card mode in its initial stage, receives a signal requesting AID information and a signal requesting mode-switching from the operation unit  1200  via the panel unit  1100 , provides retrieved AID information, wakes up and operates a corresponding driving applet, performs switching to read mode, and returns a response signal indicative of results corresponding to a request signal to the operation unit  1200  via the panel unit  1100 . 
         [0241]    After the NFC mobile terminal  1500  has been automatically switched to read mode, the NFC mobile terminal  1500  receives a tag applet from the operation unit  1200 , and outputs the tag applet via its own output unit using an operating driving applet in the form of multimedia. 
         [0242]    The configuration according to the fifth embodiment of the present invention converts commodity information recorded in a QR code or an optical code represented on the surface of a commodity into a tag applet and transfers the tag applet to the NFC mobile terminal, and, the NFC mobile terminal receives the tag applet using an NFC method and outputs the commodity information using a waked driving applet in the form of multimedia content. 
         [0243]      FIG. 11  is a functional block diagram illustrating the configuration of a commodity information provision system according to a sixth embodiment of the present invention. 
         [0244]    Referring to  FIG. 11 , the commodity information provision system  2000  according to the sixth embodiment of the present invention will now be described in detail. The commodity information provision system  2000  according to the sixth embodiment of the present invention includes an apparatus unit  2090  including a panel unit  2100  and operation unit  2200  and a server unit  2300 . 
         [0245]    The apparatus unit  2090  includes the panel unit  2100  and the operation unit  2200 , and may be any one of an NFC reader and a mobile terminal, which is the same throughout the following description. 
         [0246]    The commodity information provision system  2000  according to the sixth embodiment is the same as the commodity information provision system  1000  of the fifth embodiment except that the commodity information provision system  2000  according to the sixth embodiment further includes a barcode scanner unit  2140  and a barcode analysis unit  2250  compared to the commodity information provision system  1000  of the fifth embodiment. 
         [0247]    That is, since the configuration of the server unit  2300  including an output unit  2120 , an NFC antenna unit  2130 , a process unit  2220 , an NFC controller unit  2230 , a tag applet recording unit  2240 , and a tag applet issuance unit  2310  is the same as that of the fifth embodiment except for reference numerals, redundant descriptions will be omitted and only necessary descriptions will be given. 
         [0248]    Therefore, the configurations of the unique barcode scanner unit  2140  and barcode analysis unit  2250  will now be described in detail. 
         [0249]    The camera unit  2110  captures a QR code, and applies the QR code to both the output unit  2120  and the QR analysis unit  2210 . The barcode scanner unit  2140  scans a barcode, and applies the scanned image to both the output unit  2120  and the barcode analysis unit  2250 . 
         [0250]    The barcode and the QR code may be the same in the type and content of information to be recorded, and may be different in the amount of information which can be recorded therein. 
         [0251]    That is, the barcode is a computer-readable 1D code, and can record a relatively limited amount of information because the amount of data which can be recorded in the barcode is small. The QR code is a computer-readable 2D code, and is widely used recently QR because it has the advantages of being able to record a maximum of 23,648 bits and also recording link information. 
         [0252]    The configuration according to the sixth embodiment of the present invention converts commodity information recorded in optical codes including a barcode and a QR code represented on the surface of a commodity  1400  into a tag applet and transfers the tag applet to the NFC mobile terminal  1500 , and the NFC mobile terminal  1500  receives the tag applet using an NFC method and outputs the commodity information using a waked driving applet in the form of multimedia content. The configuration, according to the sixth embodiment is different from the configuration of the present invention in that the configuration according to the sixth embodiment uses both the barcode and the QR code. 
         [0253]      FIG. 12  is a functional block diagram illustrating the configuration of a commodity information provision system  3000  according to a seventh embodiment of the present invention. 
         [0254]    Referring to  FIG. 12 , the commodity information provision system  3000  according to the seventh embodiment of the present invention will now be described in detail. The commodity information provision system  3000  according to the seventh embodiment of the present invention includes an apparatus unit  3090  including a panel unit  3100  and an operation unit  3200  and a server unit  3300 . 
         [0255]    The apparatus unit  3090  includes the panel unit  3100  and the operation unit  3200 , and may be any one selected from among an NFC reader and a mobile terminal, which is the same throughout the following description. 
         [0256]    The commodity information provision system  3000  according to the seventh embodiment is the same as the commodity information provision system  1000  according to the fifth embodiment except that the output unit  3120  of the panel unit  3100  is connected to both a camera unit  3110  and the operation unit  3200 , the operation unit  3200  further includes an output control unit  3250 , and the server unit  3300  further includes a commodity information DB unit  3320  and a control unit  3330 . 
         [0257]    Since the other configurations of the commodity information provision system  3000  according to the seventh embodiment is the same as the commodity information provision system  1000  according to the fifth embodiment except for reference numerals, redundant descriptions will be omitted and only necessary descriptions will be given. 
         [0258]    The output unit  3120  of the panel unit  3100  visually outputs video signals captured by the camera unit  3110 , thereby allows whether the camera unit  3110  is accurately capturing an optical code to be checked, and also outputs a multimedia content signal selectively applied by the operation unit  3200 . 
         [0259]    The output control unit  3250  of the operation unit  3200  applies the tag applet, applied by the server unit  3300 , to the output unit  3120  under the control of the process unit  3220 , thereby allowing the output unit  3120  to be output in the form of a multimedia signal. 
         [0260]    That is, the process unit  3220  provides the information of the tag applet, applied by the server unit  3300 , to both the NFC controller unit  3230  and the output control unit  3250  at the same time. 
         [0261]    The server unit  3300  receives the commodity data applied via the operation unit  3200 , and applies the commodity data to the tag applet issuance unit  3310  and the commodity information DB unit  3320 . 
         [0262]    The tag applet issuance unit  3310  converts the commodity data, applied by the operation unit  3200 , into a tag, applet, as described in the descriptions of the fifth and sixth embodiments. 
         [0263]    The commodity information DB unit  3300  analyzes the commodity data applied by the operation unit  3200 , and, if link information is included in the commodity data, extracts the link information and connects to the corresponding link, thereby searching for and providing the corresponding commodity information. 
         [0264]    The control unit  3330  performs control so that the corresponding commodity information found by the commodity information DB unit  3320  can be applied to the tag applet issuance unit  3310  and converted into a tag applet. In this case, the control unit  3330  performs control and monitoring so that the commodity information is converted into a tag applet which matches commodity data included in an optical code. 
         [0265]    The server unit  3300  provides the tag applet, issued and created by the tag applet issuance unit  3310 , to the process unit  3220  of the operation unit  3200 . 
         [0266]    The configuration according to the seventh embodiment of the present invention converts commodity information, recorded in a QR code or an optical code represented on the surface of a commodity, into a tag applet, transfers the tag applet to the NFC mobile terminal, and also searches for and includes more commodity information linked using link information, thereby transferring the matched tag applet to the NFC mobile terminal. The NFC mobile terminal receives the tag applet using an NFC method, and outputs commodity information using a waked driving applet in the form of multimedia content. 
         [0267]      FIG. 13  is a functional block diagram illustrating the configuration of a commodity information provision system  4000  according to a eighth embodiment of the present invention. 
         [0268]    Referring to  FIG. 13 , the commodity information provision system  4000  according to the eighth embodiment of the present invention will now be described in detail. The commodity information provision, system  4000  according to the eighth embodiment of the present invention includes an apparatus unit  4090  including a panel unit  4100  and an operation unit  4200  and a server unit  4300 . The commodity information provision system  4000  according to the eighth embodiment is similar to the commodity information provision system  3000  according to the seventh embodiment. 
         [0269]    The apparatus unit  4090  includes the panel unit  4100  and the operation unit  4200 , and may be any one selected from among an NFC reader and a mobile terminal, which is the same throughout the following description. 
         [0270]    The commodity information provision system  4000  according to the eighth embodiment is different from the commodity information provision system  3000  according to the seventh embodiment in that the panel unit  4100  further includes a barcode scanner unit  4140  and the operation unit  4200  further includes a barcode analysis unit  4260 . Since the commodity information provision system  4000  according to the eighth embodiment is the same as the commodity information provision system  3000  according to the seventh embodiment except for reference numerals, redundant descriptions will be omitted and only necessary descriptions will be given. 
         [0271]    The camera unit  4110  captures a QR code and applies the captured image to both the output unit  4120  and the QR analysis unit  4210 , and the barcode scanner unit  4140  scans a barcode and applies the scanned image to both the output unit  4120  and the barcode analysis unit  4260 . 
         [0272]    The barcode and the QR code are the same in the type and content of information to be recorded, and are different in the amount of information which can be recorded therein, as described above. 
         [0273]    The configuration according to the eighth embodiment of the present invention has the advantage of converting commodity information, recorded in optical codes including a QR code and a barcode represented on the surface of a commodity, and commodity information, found using link information, into a tag applet and outputting the tag applet via the NFC mobile terminal. 
         [0274]      FIG. 14  is a functional block diagram illustrating the configuration of a commodity information provision system  5000  according to a ninth embodiment of the present invention. 
         [0275]    Referring  FIG. 14 , the commodity information provision system  5000  according to the ninth embodiment of the present invention will now be described in detail. The commodity information provision system  5000  according to the ninth embodiment of the present invention includes an apparatus unit  5090  including a panel unit  5100  and an operation unit  5200 . The commodity information provision system  5000  according to the ninth embodiment is partially the same as the commodity information provision system  4000  according to the eighth embodiment. 
         [0276]    The apparatus unit  5090  includes the panel unit  5100  and the operation unit  5200 , and may be any one selected from among an NFC reader and a mobile terminal, which is the same throughout the following description. 
         [0277]    Since the panel unit  5100  includes a camera unit  5110 , an output unit  5120 , an NFC antenna unit  5130  and a barcode scanner unit  5140  and is the same as the panel unit  4100  of the eighth embodiment except for reference numerals, a redundant description thereof will be omitted here. 
         [0278]    The operation unit  5200  includes a QR analysis unit  5210 , a process unit  5220 , an NFC controller unit  5230 , a tag applet recording unit  5240 , an output control unit  5250 , a barcode analysis unit  5260 , and a tag applet issuance unit  5270 . 
         [0279]    The configuration of the operation unit  5200  according to the ninth embodiment is different from that of the operation unit  4200  according to the eighth embodiment in that the operation unit  5200  further includes a tag applet issuance unit  5270  and the process unit  5220  is not connected to a server unit. 
         [0280]    That is, in the ninth embodiment, a server unit is not provided and instead the functionality of the server unit is performed by the tag applet issuance unit  5270  of the operation unit  5200 , so that the additional functionality of the process unit  5220  and the additionally provided tag applet issuance unit  5270  will now be described chiefly. 
         [0281]    The process unit  5220  recognizes a QR code captured by the QR analysis unit  5210 , and receives analyzed commodity data. 
         [0282]    Furthermore, the process unit  5220  recognizes a barcode scanned by the barcode analysis unit  5260 , and receives analyzed commodity data. 
         [0283]    The process unit  5220  transfers commodity information, received from the QR analysis unit  5210  and the barcode analysis unit  5260 , to the tag applet issuance unit  5270 . 
         [0284]    The commodity, information according to the ninth embodiment is information that an optical code can include therein, and includes one or more of the advertisement, manufacturer, vendor, release date, expiration date, price information, serial number, name and contact information of a corresponding commodity  1400 . That is, since the commodity information according to the ninth embodiment does not include image information and link information, the amount of information which can be provided may be relatively small. 
         [0285]    The tag applet issuance unit  5270  converts the commodity data, applied by the process unit  5220 , into a tag applet, and applies the tag applet to both the NFC controller unit  5230  and the process unit  5220 . 
         [0286]    The NFC controller unit  5230  records the applied tag applet in the assigned area of the tag applet recording unit  5240 , and provides the applied tag applet if it is determined that the NFC mobile terminal  1500  has tagged the NFC antenna unit  5130 . 
         [0287]    The process unit  5220  provides the tag applet, applied by the tag applet issuance unit  5270 , to the output control unit  5250 , thereby allowing the tag applet to be output via the output unit  5120 . 
         [0288]    The configuration according to the ninth embodiment of the present invention has the advantages of converting commodity information, recorded in optical codes including a QR code and a barcode represented on the surface of a commodity, into a tag applet in the operation unit itself, outputting the tag applet via the output unit in the form of content and wirelessly providing the tag applet to the NFC mobile terminal to be output. 
         [0289]      FIG. 15  is a functional block diagram illustrating the configuration of a commodity information provision system  6000  according to a tenth embodiment of the present invention. 
         [0290]    Referring to  FIG. 15 , the commodity information provision system  6000  according to the tenth embodiment of the present invention, will now be described in detail. The commodity information provision system  6000  according to the tenth embodiment of the present invention includes an apparatus unit  6090  including a panel unit  6100  and an operation unit  6200  and a server unit  6300 , and is partially the same as the commodity information provision system  5000  according to the ninth embodiment. 
         [0291]    The apparatus unit  6090  includes the panel unit  6100  and the operation unit  6200 , and may be any one selected from among an NFC reader and a mobile terminal, which is the same throughout the following description. 
         [0292]    Since the panel unit  6100  includes a camera unit  6110 , an output unit  6120 , an NFC antenna unit  6130  and a barcode scanner unit  6140  and is the same in configuration as the panel unit  5100  of the ninth embodiment, a redundant description thereof will be omitted and only descriptions necessary to describe the tenth embodiment will be given. 
         [0293]    The operation unit  6200  includes a QR analysis unit  6210 , a process unit  6220 , an NFC controller unit  6230 , a tag applet recording unit  6240 , an output control unit  6250 , a barcode analysis unit  6260 , and a tag applet issuance unit  6270 . 
         [0294]    The server unit  6300  includes a commodity information DB unit  6310  and a tag applet issuance unit  6320 , the commodity information DB unit  6310  records a variety of commodity information linked using link information, and the tag applet issuance unit  6320  converts commodity information into a tag applet. 
         [0295]    Since the configuration of the operation unit  6200  of the tenth embodiment is different from the configuration of the operation unit  5200  of the ninth embodiment in that the process unit  6220  directly connects to the NFC controller unit  6230  or connects to the NFC controller unit  6230  via the tag applet issuance unit  6270 , different and necessary descriptions will be given chiefly. 
         [0296]    The process unit  6220  checks whether link information has been included in the commodity data applied by the QR analysis unit  6210  by analyzing the commodity data. 
         [0297]    Here, the process unit  6220  checks whether link information is included in the commodity data provided by the barcode analysis unit by analyzing the commodity data. 
         [0298]    It will be apparent that link information may be also included in a barcode. 
         [0299]    The process unit  6220  analyzes commodity data applied by the QR analysis unit  6210  or barcode analysis unit  6260 , separates link information if the link information has been included in the commodity data, and applies (transfers) the link information to the server unit  6300 . 
         [0300]    That is, the process unit  6220  according to the tenth embodiment is different from the process unit  5220  according to the ninth embodiment in that the function of checking whether link information has been included, separating the link information and transferring the link information to the server unit has been added to the function of the process unit  5220  according to the ninth embodiment. 
         [0301]    Using a process of connecting to a path corresponding to link information applied by the process unit  6220 , the server unit  6300  searches for corresponding commodity information from the commodity information DB unit  6310  and applies the found commodity information to the tag applet issuance unit  6320 . 
         [0302]    The tag applet issuance unit  6320  converts the found and applied commodity information into a tag applet, and provides the commodity information to the process unit  6220  of the operation unit  6200 . 
         [0303]    The process unit  6220  directly applies (transfers) the tag applet, applied by the server unit  6300 , to both the NFC controller unit  6230  and the output control unit  6250 . 
         [0304]    Meanwhile, the process unit  6220  performs control so that the commodity information applied by the QR analysis unit  6210  is applied (transferred) to the tag applet issuance unit  6270  and then converted into a tag applet, the tag applet issuance unit  6270  applies (transfers) the tag applet, obtained by converting the commodity information, both the NFC controller unit  6230  and the process unit  6220 , and the process unit  6220  applies (transfers) the tag applet to the output control unit  6250 . 
         [0305]    The NFC controller unit  6230  is different in that it includes the functionality described in conjunction with the ninth embodiment and additionally receives the tag applets from both the tag applet issuance unit  6270  and the process unit  6220 . Since the configurations and functionalities of the tag applet recording unit  6240 , the output control unit  6250 , the QR analysis unit  6210  and the barcode analysis unit  6260  are the same as those of the ninth embodiment, redundant descriptions thereof will be omitted here. 
         [0306]    The configuration according to the tenth embodiment of the present invention converts commodity information, recorded on optical codes including a QR code and a barcode represented on the surface of a commodity, into a tag applet using the operation unit itself. 
         [0307]    In particular, the configuration according to the tenth embodiment of the present invention has the advantage of additionally providing a variety and abundance of commodity information because the configuration detects link information included in a QR code and a barcode, searches for corresponding commodity information from the server unit, converts the commodity information into a tag applet, and provides the tag applet. 
         [0308]      FIG. 16  is a signal flow diagram illustrating the operation of the commodity information provision system according to the fifth embodiment of the present invention. 
         [0309]    Referring to  FIG. 16 , the operation of the fifth embodiment will now be described in detail based on the configuration of the eighth embodiment. 
         [0310]    The NFC mobile terminal  1500  operates in card mode in its initial stage, and the operation unit  4200  operates in read mode in its initial stage. 
         [0311]    An optical code of a commodity  1400  is scanned by bringing the optical code close to the panel unit  4100  at step ST 5010 , the panel unit  4100  transfers the scanned optical code to the operation unit  4200 , and the operation unit recognizes the optical code and converts the optical code into commodity data at step ST 5020 . 
         [0312]    The operation unit transmits the obtained commodity data to the server unit at step ST 5030 , and the server unit checks whether link information has been included in commodity data by analyzing the commodity data at step ST 5040 , makes a connection using the corresponding link information if the link information has been included, and searches for commodity information at step ST 5050 . 
         [0313]    The server unit converts the commodity data, applied by the operation unit, into a tag applet and issues the tag applet, converts the commodity data and, matched commodity information into a tag applet and issues the tag applet if the commodity information has been found using a link at step ST 5060 , and transmits the tag applet to the operation unit at step ST 5070 . 
         [0314]    The operation unit records the tag applet, transmitted by the server unit, in an assigned area at step ST 5080 , checks whether the NFC mobile terminal  1500  has performed tagging by monitoring the panel unit, and, if the NFC mobile terminal  1500  has performed tagging at step ST 5090 , requests the NFC mobile terminal to search for AID information via the panel unit and at the same time requests automatic mode-switching, and receives corresponding results in the form of a response signal at step ST 5100 . 
         [0315]    In this case, the NFC mobile terminal wakes up the driving applet and operates the driving applet in an active state and switches from card mode to read mode at step ST 5110 , and the operation unit switches from read mode to card mode at step ST 5120 . 
         [0316]    The operation unit which has switched to card mode transmits the recorded tag applet to the NFC mobile terminal via the panel unit using, for example, a frequency in the 13.56 MHz band, and the NFC mobile terminal returns a response signal indicative of reception without error at step ST 5130 . 
         [0317]    If it is determined that the tag applet has been transmitted without error, the operation unit deletes a record of the corresponding tag applet at step ST 5140 , and the NFC mobile terminal outputs the commodity information by running the received tag applet at step ST 5150 . 
         [0318]    The present invention has the advantage of downloading commodity information to the NFC mobile terminal in the form of content using an optical code including a barcode or a QR code represented on a commodity and conveniently playing back and viewing the commodity information anytime and anywhere. 
         [0319]      FIG. 17  is a signal flow diagram illustrating the operation of the commodity information provision system according to the sixth embodiment of the present invention. 
         [0320]    Referring to  FIG. 17 , the operation of the commodity information provision system according to the sixth, embodiment of the present invention will now be described based on the configuration of the eighth embodiment. 
         [0321]    The operation of the commodity information provision system according to the sixth embodiment of the present invention is different in that the initial operating modes of the NFC mobile terminal  1500  and the operation unit  4200  are not designated and set. 
         [0322]    That is, the NFC mobile terminal  1500  and the operation unit  4200  automatically switches between read mode and card mode. 
         [0323]    Therefore, the operation of the commodity information provision system according to the sixth embodiment is different from the operation of the commodity information provision system according to the fifth embodiment in that the process of making a mode-switching request and transmitting a corresponding response signal is not required. 
         [0324]    Only different descriptions will now be given. 
         [0325]    In an initial stage, the NFC mobile terminal  1500  and the operation unit  4200  operate in read mode or card mode, and automatically switch operating mode every period of time which is freely set. 
         [0326]    Since steps ST 6010  to ST 6090  in  FIG. 17  are the same as steps ST 5010  to ST 5090  in the operation of the fifth embodiment, redundant descriptions thereof will be omitted here. 
         [0327]    The operation unit  4200  monitors the panel unit  4100 , and, if it is determined that the NFC mobile terminal  1500  has performed tagging, requests the NFC mobile terminal to search for AID information and the receives AID information of search results in the form of a response signal at step ST 6100 . 
         [0328]    The NFC mobile terminal wakes up the driving applet and operates the driving applet in an active state, and activates the loop time of read mode and automatically switches to read mode at step ST 6110 . 
         [0329]    The operation unit also activates the loop time of card mode and automatically switches to card mode at step ST 6120 . 
         [0330]    Furthermore, since steps ST 6130  to ST 6150  in  FIG. 17  are the same as steps ST 5130  to ST 5150  in the operation of the fifth embodiment, redundant descriptions thereof will be omitted here. 
         [0331]    The operation of the sixth embodiment has the advantage of the step of processing signals being simplified because the NFC mobile terminal  1500  and the operation unit  4200  do not exchange signals for mode-switching, thereby increasing processing speed. 
         [0332]      FIG. 18  is a diagram illustrating an NFC tag generation device  20  and a mobile terminal  10  according to an embodiment of the present invention, and  FIG. 19  is a diagram showing the configuration of an NFC tag generation device  20  according to an embodiment of the present invention. 
         [0333]    Referring to  FIG. 18 , the NFC tag generation device  20  according to the embodiment of the present invention outputs content including a still image(s), a moving image(s) and/or music to the outside, and plays back the content. 
         [0334]    A user may bring the NFC communication-enabled NFC terminal  10  close to the NFC tag generation device  20 , and receive content including a still image(s), a moving image(s) or music in the form of tag data. 
         [0335]    Referring to  FIG. 19 , the NFC tag generation device  20  for outputting content to the outside and transmitting tag data to the NFC terminal  10  includes an NFC controller unit  210 , an operation control unit  220 , a memory unit  230 , a tag recording unit  240 , a content output unit  250 , an NFC antenna unit  260 , and a communication interface unit  270 . 
         [0336]    The NFC tag generation device  20  may output one or more pieces of content via the content output unit  250 . 
         [0337]    The content may include a medium (media) which can be played back, such as a still image(s), such as a photo(s), a moving image(s) or music. 
         [0338]    The content output unit  250  may receive a selection of content using the user&#39;s manipulation or predetermined default setting. 
         [0339]    For example, when the content output unit  250  is provided with a touch screen and one or more pieces of content are alternately output at regular intervals, the user may transfer a command to select content to be transmitted to the NFC terminal  10  in such a way as to touch the touch screen. 
         [0340]    According to an embodiment of the present invention, when the user does not directly transmit a selection command to the content output unit  250  but brings the NFC terminal  10  close to the NFC tag generation device  20 , the tag generation device  20  detects a signal from the NFC terminal  10 . 
         [0341]    Accordingly, specific content may be selected by predetermined default setting without requiring a content selection command via the content output unit  250 . 
         [0342]    The operation control unit  220  may search for tag data corresponding to content selected via the content output unit  250 . 
         [0343]    There are tag data which corresponds to each of one or more pieces of content which are output to the outside via the content output unit  250 . 
         [0344]    Once the content has been selected via the content output unit  250 , the operation control unit  220  may detect a selected command signal and search for tag data, corresponding to the content. 
         [0345]    The NFC controller unit  210  may select transmission mode corresponding to the content selected by the content output unit  250 . 
         [0346]    The operation control unit  220  transmits a control signal requesting switching to transmission mode corresponding to the selected content to the NFC controller unit  210 . 
         [0347]    Methods of transmitting data using NFC communication may be classified into card mode, P2P mode, and RW mode. The transmission method may vary with mode depending on the type of content, or all transmission methods may be used. 
         [0348]    According to an embodiment of the present invention, it is possible to use a method in which mode-switching stops in corresponding transmission mode when a transmission method corresponding to content is determined in a mode polling state where card mode, P2P mode and RW mode are alternating.
