Summary of the Invention
Problems to be Solved by the Invention
[0004] By the way, in a communication system that distributes predetermined content to a terminal carried by a user via NFC communication, there is a requirement to vary the content to be distributed according to the user's attributes.
[0005] An object of the present disclosure is to provide a communication system that can acquire different redirect information for a user terminal device with a simple configuration.
Means for Solving the Problems
[0006] A communication system according to one aspect for achieving the above object is a communication system including a server, a plurality of electronic tags, and a user terminal device that reads tag identification information for identifying the electronic tags from the electronic tags. The server comprises an acquisition unit that acquires the tag identification information from the user terminal device, a storage unit that stores redirect information linked to the tag identification information, and a control unit that transmits the redirect information linked to the acquired tag identification information to the user terminal device. The control unit transmits the redirect information to the user terminal device in the order in which the tag identification information was obtained from the user terminal device.
[0007] According to the communication system with the above configuration, the server's control unit transmits predetermined redirect information to user terminal devices in the order in which the tag identification information was read from the electronic tags. Therefore, it is possible for users to obtain different redirect information from each other with a simple configuration. [Effects of the Invention]
[0008] According to this disclosure, it is possible to provide a communication system that can obtain different redirection information for user terminal devices with a simple configuration. [Brief explanation of the drawing]
[0009] [Figure 1] Figure 1 is a configuration diagram showing an example of a communication system related to this disclosure. [Figure 2] Figure 2 is an example of redirection information and other data stored in the memory unit. [Figure 3] Figure 3 is a flowchart illustrating an example of an information processing method performed in the communication system of this disclosure. [Figure 4] Figures 4(a) and 4(b) illustrate web pages displayed on a user terminal device in the communication system of this disclosure. [Modes for carrying out the invention]
[0010] (Overall structure) Hereinafter, embodiments of the present disclosure will be described in detail with reference to the drawings. Figure 1 is a configuration diagram showing an example of a communication system 100 according to the present disclosure. As illustrated in Figure 1, the communication system 100 comprises a plurality of electronic tags 1, a user terminal device 2, a server 3, and a facility control unit 4. The user terminal device 2, the server 3, and the facility control unit 4 may be connected to each other in a manner that enables communication, for example, via a communication network N such as the Internet.
[0011] Electronic tag 1 is a tag that utilizes RFID (Radio Frequency Identification) technology to read and write data to the IC chip inside the tag without contact using radio waves. "NFC tag" is one of the standards for electronic tags, and in the following embodiment, an example using an NFC tag as electronic tag 1 will be described, but electronic tag 1 is not limited to an NFC tag. Electronic tag 1 is, for example, an NFC tag. Note that an NFC tag is a tag that uses a frequency of 13.56 MHz and uses short-range wireless communication of about 10 cm, which is relatively shorter than other RFID tags. Note that electronic tag 1 may be any other electronic tag that uses short-range wireless communication of a similar degree as an NFC tag. Electronic tag 1 is, for example, a sheet-type tag or a card-type tag, and is relatively thin. Each electronic tag 1 has tag identification information for identifying electronic tag 1. Tag identification information is, for example, an identification number (ID) assigned to each electronic tag 1.
[0012] The electronic tag 1 is installed, for example, within a designated facility. Multiple electronic tags 1 may be installed at different locations within the designated facility. The electronic tag 1 is capable of short-range wireless communication with, for example, a user terminal device 2. The electronic tag 1 may also be designed to correspond to the functions it provides. The functions provided by the electronic tag 1 may include, for example, an intercom function, an emergency call function, or a facility unlocking function. If the function provided by the electronic tag 1 is, for example, an intercom function, then the electronic tag 1 will be designed to resemble an intercom.
[0013] User terminal device 2 is, for example, an information terminal device such as a smartphone. User terminal device 2 includes a first user terminal device 2A operated by a first user and a second user terminal device 2B operated by a second user different from the first user. When each user terminal device 2A, 2B communicates wirelessly with the electronic tag 1, it reads the tag identification information from the electronic tag 1. After reading the tag identification information from the electronic tag 1, user terminal device 2 transmits the tag identification information to the server 3.
[0014] Server 3 comprises an acquisition unit 31, a storage unit 32, and a control unit 33. These are connected to each other via a bus 34 so that they can communicate with one another.
[0015] The acquisition unit 31 acquires tag identification information from the user terminal device 2 via the communication network N. The acquisition unit 31 transmits the acquired tag identification information to the control unit 33.
[0016] The storage unit 32 is, for example, a storage device such as an HDD (Hard Disk Drive), SSD (Solid State Drive), or flash memory. The storage unit 32 stores redirect information and facility information, linked to the acquisition order of tag identification information (tag ID), as illustrated in Figure 2. The acquisition order of tag identification information is the order in which the server 3 acquires tag identification information transmitted from a single user terminal device 2. Details of the acquisition order will be described later. Redirect destination information is, for example, information indicating what kind of web page the URL indicated by the URL information is. Redirect information can also be prepared in advance for each language (Japanese, English, etc.). Facility information is information indicating the facility where the facility control unit 4 is installed. Examples of facilities include medical facilities such as hospitals, residential facilities such as apartments, offices, department stores, sports gyms, and other commercial facilities. Facility information includes, for example, facility name information indicating the name of the facility where the facility control unit 4 is installed, and facility address information indicating the address of the facility. Furthermore, redirect information and facility information can be edited (created, modified, or deleted) by a second user, for example.
[0017] Returning to FIG. 1, the control unit 33 will be described. As a hardware configuration, the control unit 33 includes a memory 331 and a processor 332. The memory 331 is composed of, for example, a ROM (Read Only Memory) in which various computer programs and the like are stored, a RAM (Random Access Memory) having a plurality of work areas in which various computer programs to be executed by the processor 332 are stored, and the like. The processor 332 is, for example, a CPU (Central Processing Unit), and is configured to expand a computer program specified from various computer programs incorporated in the ROM onto the RAM and execute various processes in cooperation with the RAM.
[0018] The control unit 33 acquires, from the storage unit 32, the redirect information associated with the acquisition order based on the acquisition order of the tag identification information acquired by the acquisition unit 31. At this time, the control unit 33 can acquire different redirect information from the storage unit 32 based on the acquisition order of the tag identification information acquired by the acquisition unit 31. For example, when the acquisition unit 31 acquires tag identification information regarding a plurality of electronic tags 1 from a single user terminal device 2, the control unit 33 acquires, from the storage unit 32, the redirect information corresponding to the acquisition order of the tag identification information. The control unit 33 transmits the redirect information acquired from the storage unit 32 to the user terminal device 2 that is the transmission source of the tag identification information.
[0019] The facility control unit 4 is, for example, an information terminal device such as a computer. Examples of facility control unit 4 include a nurse call control unit and a nurse call master unit. When facility control unit 4 is a nurse call control unit, the control unit 33 can associate facility control unit 4 with multiple electronic tags 1, thereby enabling it to transmit appropriate redirect information based on the information from facility control unit 4 to a user terminal device 2 that has read an electronic tag 1 installed within the hospital facility. Alternatively, facility control unit 4 may be an intercom control unit or intercom master unit installed in an apartment building or other multi-unit dwelling. When facility control unit 4 is an intercom control unit, the control unit 33 can associate facility control unit 4 with multiple electronic tags 1, thereby enabling it to transmit appropriate redirect information based on the information from facility control unit 4 to a user terminal device 2 that has read an electronic tag 1 installed within the apartment building. Furthermore, when facility control unit 4 is an intercom control unit, facility control unit 4 can control the electric locks of the apartment building. The facility controller 4, in response to an unlock request signal transmitted from the user terminal device 2 or server 3 that reads the electronic tag 1, unlocks the facility indicated by the facility information linked to the tag identification information acquired by the acquisition unit 31. In other words, the facility controller 4 can change the state of the electric lock of a facility such as an apartment building where the facility controller 4 is installed from a locked state to an unlocked state in response to an unlock request signal.
[0020] Next, while referring to FIGS. 2 to 4, an information processing method executed in the communication system 100 of the present disclosure will be described. FIG. 3 is a flowchart diagram illustrating the information processing method executed in the communication system 100. FIGS. 4(a) and (b) are examples of web pages displayed on each user terminal device 2 based on the fact that each user terminal device 2 has been brought close to the electronic tag 1. In the present embodiment, the first user terminal device 2A is a portable terminal such as a smartphone carried by the first user who is an inpatient in Hospital A shown in FIG. 2, and the second user terminal device 2B is a portable terminal such as a smartphone or a tablet carried by the second user who is a nurse in Hospital A. Further, the facility control device 4 is a nurse call control device or a nurse call master device installed in Hospital A. An electronic tag 1A is installed near the bed in the hospital room where the first user is admitted, and an electronic tag 1B different from the electronic tag 1A in the hospital room is installed in the nurse station where the facility control device 4 is installed.
[0021] First, an information processing method when the first user terminal device 2A of the first user who is an inpatient in Hospital A acquires redirect information via the electronic tag 1A will be described with reference to FIG. 3. As illustrated in FIG. 3, when the first user brings the first user terminal device 2A close to the electronic tag 1A, the first user terminal device 2A performs short-range wireless communication with the electronic tag 1A and reads tag identification information from the electronic tag 1A (STEP01). In the present embodiment, the first user brings his / her smartphone close to the electronic tag 1A installed near the bed. When the first user's smartphone is brought close to the electronic tag 1A, the smartphone reads tag identification information from the electronic tag 1A. Then, the first user terminal device 2A, which is the first user's smartphone, transmits the tag identification information read from the electronic tag 1A to the server 3 (STEP02).
[0022] When tag identification information is transmitted from the first user terminal device 2A to the server 3, the control unit 33 of the server 3 determines whether the tag identification information (tag ID) acquired by the acquisition unit 31 is T1 as shown in Figure 2 (STEP 03). In the "Tag ID Acquisition Order" column of Figure 2, T1 is the tag identification information of electronic tag 1A, and T2 is the tag identification information of electronic tag 1B. As shown in Figure 2, the storage unit 32 stores redirect information associated with the acquisition order of the tag IDs. In this example, the server 3 has acquired the tag identification information T1 of electronic tag 1A from the first user terminal device 2A. Therefore, the control unit 33 determines that STEP 03 is YES and executes the process of STEP 04.
[0023] In STEP 04, the control unit 33 determines whether the acquisition unit 31 has acquired tag identification information T2 before tag identification information T1. In this example, the server 3 has acquired only the tag identification information T1 of the electronic tag 1A from the first user terminal device 2A. Therefore, the control unit 33 determines that it has not acquired tag identification information T2 before the tag identification information T1 of the electronic tag 1A (NO in STEP 04), and acquires redirect information with redirect number "1" in which only tag identification information T1 is included in the acquisition order from the storage unit 32 (STEP 05). In this case, the control unit 33 acquires redirect information from the storage unit 32 indicating that the redirect URL is http: / / www... and the redirect destination is a hospital information webpage. The hospital information webpage is a webpage for the first user, who is an inpatient, to acquire various information within Hospital A.
[0024] Next, the control unit 33 transmits the redirect information received from the storage unit 32 to the first user terminal device 2A (STEP 06). When the first user terminal device 2A receives the redirect information from the server 3, it displays the web page or the like related to the redirect URL indicated by the redirect information on the display unit of the first user terminal device 2A (STEP 07). In this embodiment, when the first user terminal device 2A receives the redirect information from the server 3, as shown in Figure 4(a), the display unit of the first user terminal device 2A displays a hospital information web page related to http: / / www.... The hospital information web page may display selection areas for obtaining various information such as "Information for Hospitalization" and "Information for Health Checkups". This makes it possible for the first user to obtain various information about hospital A through the hospital information web page.
[0025] Next, we will explain the information processing method when the second user terminal device 2B of the second user, who is a nurse at Hospital A, reads multiple electronic tags 1A and 1B and obtains redirect information, referring again to Figure 3. First, the second user brings the second user terminal device 2B close to the electronic tag 1B installed near the nurse call master unit (an example of the facility control unit 4) in the nurse station. When the second user brings the second user terminal device 2B close to the electronic tag 1B, the second user terminal device 2B communicates with the electronic tag 1B via short-range wireless communication and reads the tag identification information from the electronic tag 1B (STEP 01). Then, the second user terminal device 2B transmits the tag identification information read from the electronic tag 1B to the server 3 (STEP 02).
[0026] When the tag identification information of electronic tag 1B is transmitted from the second user terminal device 2B to server 3, the control unit 33 of server 3 determines whether the tag identification information (tag ID) acquired by the acquisition unit 31 is T1 as shown in Figure 2 (STEP03). In this example, server 3 has acquired T2, which is the tag identification information of electronic tag 1B, from the second user terminal device 2B. Therefore, the control unit 33 determines that STEP03 is NO and returns the process to STEP01.
[0027] Suppose the second user, a nurse, then visits the hospital room of the first user, a hospitalized patient. The second user then brings their smartphone, the second user terminal device 2B, close to the electronic tag 1A installed in the first user's room. When the second user terminal device 2B is brought close to the electronic tag 1A, the second user terminal device 2B reads the tag identification information from the electronic tag 1A (STEP 01). The second user terminal device 2B then transmits the tag identification information read from the electronic tag 1A to the server 3 (STEP 02).
[0028] When the tag identification information of electronic tag 1A is transmitted from the second user terminal device 2B to server 3, the control unit 33 of server 3 determines whether the tag identification information (tag ID) acquired by the acquisition unit 31 is T1 as shown in Figure 2 (STEP 03). Server 3 has acquired T1, which is the tag identification information of electronic tag 1A, from the second user terminal device 2B. Therefore, the control unit 33 determines that STEP 03 is YES and proceeds to execute STEP 04.
[0029] In STEP 04, the control unit 33 determines whether the acquisition unit 31 has acquired tag identification information T2 before tag identification information T1. The second user's second user terminal device 2B reads tag identification information from electronic tag 1A after reading tag identification information from electronic tag 1B. Therefore, the server 3 has acquired the tag identification information T2 of electronic tag 1B from the second user terminal device 2B before the tag identification information T1 of electronic tag 1A. As a result, the control unit 33 determines that tag identification information T2 has been acquired before the tag identification information T1 of electronic tag 1A (YES in STEP 04), and acquires redirect information with redirect number "2" from the storage unit 32, where tag identification information T2 is the first acquisition priority and tag identification information T1 is the second acquisition priority, i.e., the acquisition order is T2 → T1 (STEP 08). In this case, the control unit 33 acquires redirect information from the storage unit 32 indicating that the redirect URL is http: / / xxx... and the redirect destination is an information display web page. The information display webpage is a webpage used to display various information about the first user, who is an inpatient in a hospital room where the electronic tag 1A is installed.
[0030] Next, the control unit 33 transmits the redirect information received from the storage unit 32 to the second user terminal device 2B (STEP 06). When the second user terminal device 2B receives the redirect information from the server 3, it displays the web page or the like related to the redirect URL indicated by the redirect information on the display unit of the second user terminal device 2B (STEP 07). In this embodiment, when the second user terminal device 2B receives the redirect information from the server 3, as shown in Figure 4(b), the display unit of the second user terminal device 2B displays the web page for displaying information related to http: / / xxx..., and the second user, who is a nurse, can check various information about the first user, who is an inpatient in the hospital room where the electronic tag 1A is installed, through the web page for displaying information.
[0031] According to the communication system 100 with the above configuration, the control unit 33 of the server 3 transmits redirect information to the user terminal devices 2A and 2B in the order in which the tag identification information of the electronic tags 1A and 1B was acquired from the user terminal devices 2A and 2B. Therefore, for example, in hospital A, the web page displayed on the first user terminal device 2A of the first user (a hospitalized patient) when it is brought close to the electronic tag 1A can be different from the web page displayed on the second user terminal device 2B of the second user (a nurse) when it is brought close to the electronic tag 1A. In other words, it becomes relatively easy to transmit different redirect information to different user terminal devices 2A and 2B. This makes it possible to provide a highly convenient communication system 100.
[0032] (Variation 1) Next, Modification 1 will be explained with reference to Figure 2. In Modification 1, the smartphone of the first user, who is a visitor to apartment building B, is designated as the first user terminal device 2A, and the smartphone of the second user, who is a resident of apartment building B, is designated as the second user terminal device 2B. Furthermore, the intercom control unit installed in apartment building B is designated as the facility control unit 4, an electronic tag 1C is installed in the entrance of apartment building B, and an electronic tag 1D is installed in the second user's room within apartment building B. In this example, when the first user terminal device 2A receives redirect information from server 3, it becomes ready to communicate with the second user terminal device 2B. This ready-to-communicate state includes the fact that both the first user terminal device 2A and the second user terminal device 2B are ready to communicate.
[0033] First, when a visitor, the first user, visits apartment building B where electronic tags 1C, 1D and facility control unit 4 are installed, the first user brings their smartphone, the first user terminal device 2A, close to the electronic tag 1C installed in the entrance of apartment building B. When the first user brings the first user terminal device 2A close to the electronic tag 1C, the first user terminal device 2A communicates with the electronic tag 1C via short-range wireless communication and reads the tag identification information from the electronic tag 1C. Then, the first user terminal device 2A transmits the tag identification information read from the electronic tag 1C to the server 3.
[0034] When tag identification information is transmitted from the first user terminal device 2A to the server 3, the control unit 33 of the server 3 determines whether the tag identification information (tag ID) acquired by the acquisition unit 31 is T3 as shown in Figure 2, and whether the acquisition unit 31 acquired tag identification information T4 before tag identification information T3. In the "Tag ID Acquisition Order" column of Figure 2, T3 is the tag identification information of electronic tag 1C, and T4 is the tag identification information of electronic tag 1D. In this example, the server 3 has acquired only the tag identification information T3 of electronic tag 1C from the first user terminal device 2A. Therefore, the control unit 33 determines that it has not acquired the tag identification information T4 of electronic tag 1D before the tag identification information T3 of electronic tag 1C, and acquires redirect information for redirect number "3" from the storage unit 32, in which only tag identification information T3 is included in the acquisition order. In this case, the control unit 33 acquires redirect information from the storage unit 32 indicating that the redirect URL is http: / / yyy... and the redirect destination is a web page for phone calls. The web page for making calls is a web page used by the first user and the second user to make calls via the first user terminal device 2A and the second user terminal device 2B.
[0035] Next, the control unit 33 transmits the redirect information received from the storage unit 32 to the first user terminal device 2A. When the first user terminal device 2A receives the redirect information from the server 3, it displays the web page or the like related to the redirect URL indicated by the redirect information on its display unit. In this example, when the first user terminal device 2A receives the redirect information from the server 3, the call web page related to http: / / yyy... is displayed on the display unit of the first user terminal device 2A. This makes it possible for the first user to make a call with the second user through the call web page. In this example, the configuration is such that the first user terminal device 2A and the second user terminal device 2B are connected via a web page for communication (calls), but this is not the only example. The first user terminal device 2A and the room master unit (an example of a user terminal device) installed in the second user's room may also be connected via a web page for communication.
[0036] Next, when a second user, a resident of apartment building B, leaves apartment building B where electronic tags 1C and 1D and the facility control unit 4 are installed, the second user first brings their smartphone, the second user terminal device 2B, close to the electronic tag 1D installed in their room. When the second user brings the second user terminal device 2B close to the electronic tag 1D, the second user terminal device 2B communicates with the electronic tag 1D via short-range wireless communication and reads the tag identification information from the electronic tag 1D. The second user terminal device 2B then transmits the tag identification information read from the electronic tag 1D to the server 3.
[0037] When the tag identification information of the electronic tag 1D is transmitted from the second user terminal device 2B to the server 3, the control unit 33 determines whether the tag identification information (tag ID) acquired by the acquisition unit 31 is T3 as shown in Figure 2, and whether the acquisition unit 31 acquired tag identification information T4 before tag identification information T3. Here, the server 3 has acquired only the tag identification information T4 of the electronic tag 1D from the second user terminal device 2B. Therefore, the control unit 33 waits until it acquires tag identification information from the second user terminal device 2B next.
[0038] Next, let's assume that the second user, who is a resident, leaves apartment building B with the second user terminal device 2B and then returns to apartment building B. Upon returning to apartment building B, the second user brings their smartphone, the second user terminal device 2B, close to the electronic tag 1C installed in the entrance of apartment building B. When the second user brings the second user terminal device 2B close to the electronic tag 1C, the second user terminal device 2B communicates with the electronic tag 1C via short-range wireless communication and reads the tag identification information from the electronic tag 1C. The second user terminal device 2B then transmits the tag identification information read from the electronic tag 1C to the server 3.
[0039] When the tag identification information of electronic tag 1C is transmitted from the second user terminal device 2B to the server 3, the control unit 33 determines whether the tag identification information (tag ID) acquired by the acquisition unit 31 is T3 as shown in Figure 2, and whether the acquisition unit 31 acquired the tag identification information T4 before the tag identification information T3. Here, the server 3 acquired the tag identification information T4 of electronic tag 1D from the second user terminal device 2B, and then acquired the tag identification information T3 of electronic tag 1C from the second user terminal device 2B. Therefore, the control unit 33 determines that the tag identification information T4 of electronic tag 1D was acquired before the tag identification information T3 of electronic tag 1C. The control unit 33 then acquires redirect information with redirect number "4" from the storage unit 32, where the tag identification information T4 is the first acquisition priority and the tag identification information T3 is the second acquisition priority, that is, the acquisition order is T4 → T3. In this case, the control unit 33 obtains redirect information from the storage unit 32 indicating that the redirect URL is http: / / zzz... and that the redirect destination is an unlocking webpage. The unlocking webpage is a webpage used to request the facility controller 4 to unlock the entrance door of apartment building B.
[0040] Next, the control unit 33 transmits the redirect information received from the storage unit 32 to the second user terminal device 2B. When the second user terminal device 2B receives the redirect information from the server 3, it displays a webpage or the like related to the redirect URL indicated by the redirect information on its display unit. In this embodiment, when the second user terminal device 2B receives the redirect information from the server 3, an unlocking webpage related to http: / / zzz... is displayed on the display unit of the second user terminal device 2B, and the second user, who is a resident of apartment building B, can request the facility controller 4 to unlock the entrance door of apartment building B through the unlocking webpage. For example, the second user requests the unlocking of the entrance door on the unlocking webpage displayed on the second user terminal device 2B. The second user terminal device 2B transmits an unlocking request signal based on the second user's unlocking request, along with the tag identification information of the electronic tags 1C and 1D read by the second user terminal device 2B, to the facility controller 4 indirectly via the server 3, or directly without going through the server 3. When the facility control unit 4 determines that the received unlock request signal is appropriate, it unlocks the facility in which the facility control unit 4 is installed. In this example, based on the unlock request signal transmitted from the second user terminal device 2B, the facility control unit 4 unlocks apartment building B, which is the facility indicated by the facility information associated with the tag identification information T3 and T4 indicating electronic tags 1C and 1D.
[0041] According to the communication system 100 described in the modified example 1 above, the control unit 33 of the server 3 transmits redirect information to the user terminal devices 2A and 2B in the order in which the tag identification information of the electronic tags 1C and 1D was acquired from the user terminal devices 2A and 2B. Therefore, for example, in an apartment building, the web page displayed on the first user terminal device 2A of a first user (a visitor) when it is brought close to the electronic tag 1C can be different from the web page displayed on the second user terminal device 2B of a second user (a resident) when it is brought close to the electronic tag 1C. This makes it possible to provide a highly convenient communication system 100 even in apartment buildings.
[0042] Furthermore, according to the communication system 100 of Modified Example 1, when the user terminal device 2 generates an unlock request signal to unlock a predetermined facility based on the acquisition order of the electronic tags 1, it transmits the generated unlock request signal to the facility controller 4 (an example of a control device) of that facility, and the facility controller 4 unlocks the facility in response to the unlock request signal. As a result, a second user, who is a resident, can unlock the entrance door of an apartment building simply by bringing their smartphone close to multiple electronic tags 1C, 1D installed in the apartment building. Thus, the communication system 100 allows for the unlocking of facilities in a simple manner.
[0043] (Modification 2) Each user terminal device 2 may store language information indicating the language used on that user terminal device 2. The language used is determined, for example, by the user of the user terminal device setting the language of the OS (Operating System). Once the language used is determined, the user terminal device 2 stores language information indicating the determined language.
[0044] In Modification 2, when the user terminal device 2 reads the tag identification information from the electronic tag 1, it transmits the language used information along with the tag identification information to the server 3. The control unit 33 obtains redirect information from the storage unit 32 based on the tag identification information and language used information received from the user terminal device 2. Specifically, when the control unit 33 obtains redirect information from the storage unit 32 based on the acquisition order of the electronic tag 1, it can take into account the language used information received from the user terminal device 2 and obtain redirect information expressed in the language used indicated by the language used information. In this case, the storage unit 32 is assumed to store redirect URLs for multiple web pages that display the same content information in different languages. For example, if the language used indicated by the language used information of the user terminal device 2 is English, the control unit 33 obtains redirect information (redirect URL) from the storage unit 32 that indicates an English web page among the predetermined redirect information corresponding to the acquisition order of the electronic tag 1. As a result, the redirect URL of the English web page containing the predetermined content information is transmitted to the user terminal device 2, and the English web page related to the redirect URL received from the server 3 is displayed on the display unit of the user terminal device 2. Thus, in Modification 2, the communication system 100 can display redirect information for a webpage in a predetermined language from among multiple webpages that display specific content information in different languages, based on the acquisition order of the electronic tags 1 read by the user terminal device 2 and the language information used by the user terminal device 2.
