Description

Technical Field [0001] The present invention relates to a system and a method for assuring safe taxi using a local communication technology,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a system and a method for assuring a safe cab by using Near Field Communication (NFC) technology. More particularly, the present invention relates to a system and method for determining whether a taxi to read from a NFC tag attached to a taxi is read from a passenger's mobile communication terminal and is to be boarded through the information.

NFC technology is a proximity wireless communication technology that enables data to be transmitted and received at a distance of about 10 cm at a frequency of 13.56 MHz. NFC technology is widely used in a variety of services such as transportation, ticket and payment. According to the white paper of the NFC Forum (January 2011), transportation services include checking the running time of public transportation, It is said that NFC technology can be utilized for taxi calling service, parking fee payment, fare payment, check-in and check-out.

In fact, New Zealand's Wellington City offers Touch2Pay service, which uses the NFC function of the LG Optimus phone to pay for taxi fares and buses. In Taiwan, They may also provide advertising or entertainment content to passengers on board (see http://www.nfc-world.com/en/cases/taxi.html).

As a conventional patent related to the present invention, Patent No. 899766 entitled " Method of monitoring a taxi for passengers using RFID and a taxi monitoring system for passengers " So that a safer cab can be used. This patent stores taxi information (a taxi company, a car number, a driver's photograph, a name, a registration expiration date, etc.) in an RFID tag provided in a taxi, and the passenger reads the taxi information from the taxi information lead means So that the taxi information can be read through the included means. The passenger receives the taxi information by carrying out infrared communication with the taxi information lead means through a mobile phone or the like carried by the passenger.

However, since the taxi information lead means must be installed in the terminal of the taxi stand, it is expensive, and only when the taxi carrying the passenger is within the distance that the taxi information lead means of the landing terminal can read, It is difficult to provide a universal service because the taxi information can be provided to passengers. In particular, it is difficult to ensure passenger safety in a place where it is difficult to install a landing terminal, such as a suburban area or an outbreak area where passenger safety is more required. Meanwhile, according to the registration bulletin paragraph 26 of the registered patent No. 899766, when it is difficult to install terminals on a platform, it is possible to inquire taxi information and use services by using a mobile terminal equipped with an RFID reader, It is not clear whether the mobile terminal is a mobile terminal carried by a passenger or a mobile terminal installed or carried by an operator of a passenger taxi monitoring system and how the mobile terminal can inquire taxi information without using the taxi information lead means There is no content to be disclosed.

Another patent related to the present invention, Patent No. 792999, entitled " Taxi Safety System Using RFID and Its Control Method "relates to the invention for preventing taxi crime and analyzing cause of accident. According to this patent, vehicle specific information is stored in an RFID tag installed inside a taxi, and the mobile communication terminals 120 and 220 owned by a passenger transmit their information to the RFID tag. Meanwhile, the mobile communication terminal 230 installed in the taxi reads out the vehicle unique number of the taxi stored in the RFID tag, the current position of the taxi, the driver's personal profile information, the taxi company code information, and the like, and transmits it to the mobile communication company server. The mobile communication company receiving the taxi information stores and manages it in the database for each customer ID.

However, this Patent No. 792999 must have an article ID card reader installed in the cab, and the taxi information must be transmitted from the article ID card reader to the RFID tag. The passenger directly inquires taxi information using his / her portable terminal, and then notifies whether the taxi is normal or not, but the taxi information is sent to the mobile communication company through the mobile communication terminal mounted in the taxi and the mobile communication company manages the customer It is difficult for passengers to respond quickly to crimes and accidents.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a safe taxi assurance system and method that can overcome the problems of the prior art and make the taxi more safe.

In order to attain the above object, the relief taxi guarantee system according to the present invention includes a vehicle information server and a vehicle information database, which are connected to a mobile communication terminal carried by a passenger who wishes to use a taxi, through a wireless communication network. The vehicle information database stores the vehicle number of the taxi, the vehicle registration information, the vehicle status information, and the serial number data of the tag attached to the taxi. The vehicle information server stores (1) tag serial number data read by the mobile communication terminal (2) decoding the received tag serial number data, (3) reading the vehicle status information corresponding to the tag serial number, (4) determining whether the vehicle is a normal vehicle, (5) transmits the determination result to the mobile communication terminal.

The method for assuring safe taxi according to the present invention is implemented by a system including a vehicle information database and a vehicle information server connected to a mobile communication terminal carried by a passenger who wishes to use a taxi via a wireless communication network, Vehicle number, vehicle registration information, vehicle status information, and serial number data of a tag attached to a taxi. The method comprises the steps of: (A) receiving a tag serial number data read from a tag by a mobile communication terminal from a tag, (B) decoding the received tag serial number data, (C) Reading the vehicle status information corresponding to the taxi corresponding to the tag serial number from the vehicle information database to determine whether the vehicle is a normal vehicle; and (D) transmitting the determination result to the mobile communication terminal .

In the safety assurance system and method according to the present invention, the NFC tag includes an intermediate layer on which a short-range communication (NFC) chip and an antenna are mounted, an upper layer on which a two-dimensional code is printed, and a lower layer having a surface adhering to the taxi, The local communication chip of the tag stores the serial number data of the tag, and the two-dimensional code contains the serial number data of the tag. When the mobile communication terminal has the local communication function or the local communication function is activated, the vehicle information server receives the tag serial number data stored in the local communication chip from the mobile communication terminal, and when the mobile communication terminal performs the local communication function When the mobile communication terminal does not have the local communication function or the local communication function is in the inactive state, the mobile communication terminal receives the tag serial number data recorded in the two-dimensional code.

According to the security system and method of the present invention, the vehicle information database stores a list indicating that the taxi is a stolen vehicle as a black list. The mobile communication terminal requests the vehicle information server to store and update the black list, When the mobile communication terminal can not be connected to the server system through the wireless communication network, the passenger can determine whether or not to ride the taxi through the black list stored in the mobile communication terminal.

The present invention provides an NFC tag and a mobile communication terminal that can be used in such a safe taxi assurance system.

According to the present invention, it is possible to more safely provide a taxi service by allowing a passenger to confirm whether or not the taxi is normal with the minimum data to determine whether the passenger is riding.

Further, according to the present invention, a third party other than the passenger can know who is aboard a taxi, and the fact that the taxi driver is aware of the taxi driver can be prevented. In addition, in the case of a stolen vehicle, when a mobile communication terminal of a passenger using a service according to the present invention is brought close to an NFC tag attached to a taxi, it is possible to prevent a passenger from boarding a taxi, The position is transmitted to the server system, and based on this, the position of the stolen vehicle can be determined and the stolen vehicle can be utilized.

Further, according to the present invention, the utilization rate of the taxi can be increased, contributing to the increase of the taxi driver's income.

According to the present invention, the serial number data of the NFC tag is encrypted and transmitted to the server system. The server system encrypts the state information of the taxi detected through the encryption and transmits it to the mobile communication terminal of the passenger. By using a symmetric key algorithm using a telephone number, it is possible to provide an excellent security service.

Further, according to the present invention, it is possible to further improve the safety of taxi use by providing a complementary safe taxi guarantee function using a black list, even when the NFC function is not available or inactive, and even when the passenger is in a shadow area.

7A and 7B are diagrams of an application screen according to the present invention.

A specific embodiment of the present invention will be described with reference to the accompanying drawings.

First, referring to FIG. 1, an NFC tag 20 is attached to a taxi 10. The passenger who wants to use the taxi reads the data (tag serial number data) stored in the NFC tag 20 by bringing the mobile communication terminal 30 carried by him into the NFC tag 20, encrypts the data, (100). The mobile communication terminal 30 and the server system 100 are connected to each other through a wireless communication network.

The server system 100 decrypts the data transmitted from the mobile communication terminal 30 and compares the decrypted data with the data stored in the database 110 to determine whether or not the taxi that the passenger intends to board is an ineligible vehicle such as a stolen vehicle, And transmits the result to the mobile communication terminal 30. On the other hand, the server system 100 transmits to the mobile communication terminal 30 the usage information of other passengers using the taxi, for example, information on the kindness of the taxi driver, service status, and customer satisfaction, in addition to information on whether or not the taxi is an ineligible vehicle . Based on the information transmitted from the server system 100, the passenger judges whether or not to board the taxi.

Since the passenger must judge whether or not the cab is to be boarded in such a short time, the NFC tag 20 is attached to the passenger's seat position, that is, near the rear seat door handle of the taxi or near the front seat door handle as shown in FIG. On the other hand, since the passenger may forget to bring the NFC tag 20 close to the mobile communication terminal 30 before boarding the taxi, it is preferable to attach the NFC tag to the inside of the taxi.

The NFC tag 20 can be fixed to the outer surface of the taxi as an attachment type as shown in FIG. However, the present invention is not necessarily implemented using an attachable NFC tag.

The attachment type NFC tag 20 shown in FIG. 2 is composed of an upper layer 22, an intermediate layer 24, and a lower layer 26. The upper layer 22 constitutes a surface exposed to the outside after the tag is attached to the taxi and the vehicle number display part 21, the warranty date display part 23, the advertisement display part 27 and the two-dimensional code 19 . The warranty number (for example, one year) of the NFC tag 20 is displayed on the guarantee date display section 23 and the advertisement display section 27 displays the warranty period Advertisements of business owners, advertisements of taxi owners, etc. are displayed. The vehicle number displayed on the vehicle number display unit 21 is used to determine which tag 20 is attached to which taxi 10. The two-dimensional code 19 will be described later.

The NFC chip 25 and the antenna 27 are mounted on the intermediate layer 24 and the lower layer 26 includes an adhesive bottom surface capable of fixing the tag 20 to the outer surface of the cab. The NFC chip 25 includes a memory (e.g., an EEPROM) for storing data (e.g., a tag serial number) according to the present invention and an RF interface (not shown) connected to the antenna 27.

The amount of data stored in the memory of the NFC chip 25 is determined in consideration of the communication speed of the NFC tag 20 and the production cost. For example, storing only simple data (e.g., server address (URL) data or tag serial number data) in the NFC tag 20 does not require a large memory capacity, resulting in a low production cost and a high communication speed. Type 1 and Type 2 tags are suitable here. If type 3 tags are used as NFC tags (20), the memory capacity is large and the speed can be made faster than types 1 and 2, but the production cost increases, and type 3 tags are often used in NFC-F tags. The Type 4 tag has a memory capacity of 32 kilobytes and is the fastest and uses NFC-A or NFC-B.

In the embodiment of the present invention, only the tag serial number data of the NFC tag 20 is stored in the memory of the NFC chip 25 in consideration of the communication speed and the production cost. The tag serial number is a number issued when the NFC tag 20 is manufactured, and has a unique value for every tag. Which taxi 10 to which the NFC tag 20 having a specific serial number is to be attached is determined by the vehicle number described in the car number display unit 21 of the tag 20. [ The tag serial number and the corresponding taxi car number data are stored in the database 110 of the server system 100 shown in Fig. 1 or the vehicle information server 120 shown in Fig.

The NFC tag can be issued by a service provider operating the server system 100 of FIG. 1. The server system operator issues the registered NFC tag 20 for each vehicle and distributes the tag to the taxi company. Attach to taxi.

3, the mobile communication terminal 30 which can be used in the present invention includes a control unit 32, a screen display unit 34, a memory 35, a user interface 36, a camera 37, an NFC interface 38, A communication unit 40, and a position sensing unit 42.

The control unit 32 is a central processing unit that controls all the operations of the mobile communication terminal 30 and is, for example, a CPU chip on which a mobile operating system is mounted. The operation of the mobile communication terminal 30 required for the present invention is also such that the operation of reading the NFC tag 20, the operation of encrypting the data read by the tag 20, and the decryption of the data transmitted from the server system 100 are also performed by the controller 32 ).

The screen display section 34 displays character data, image data, moving image data, etc. processed by the control section 32 as a liquid crystal display (LCD) on the screen. The data necessary for the present invention and the interface necessary for the passenger's instruction can be displayed on the screen display section 34 as well.

The memory 35 stores data necessary for the operation of the mobile communication terminal 30 and may backup and store data (i.e., a black list) stored in the database 110 of the server system 100 as described later . The memory 35 shown in FIG. 3 is not necessarily composed of only one memory chip, but may be configured to include a memory serving as a main memory and a memory serving as an auxiliary memory.

The user interface 36 recognizes that the passenger manipulates the mobile communication terminal 30 or executes an application program (or an app). The user interface 36 may be implemented as a GUI (Graphic User Interface) on the screen display unit 34, for example.

The camera 37 is an optical device capable of photographing a subject. In the present invention, the camera 37 is a digital camera used to read a two-dimensional code ('19' in FIG. 2) formed on the surface of the NFC tag 20.

The NFC interface 38 includes an NFC chip set performing an NFC function, an NFC antenna, and a security module. Meanwhile, the NFC interface 38 may be implemented by a SIM (Subscriber Identification Module) card or a Universal Subscriber Identification Module (USIM) card. Such a USIM card is, for example, a card incorporating a 13.56 MHz antenna, an NFC chipset, and a USIM chip. The NFC interface 38 transmits and receives data at a rate of 106 kbps to 847 kbps through the electromagnetic field induction method and the NFC tag 20 located within 10 cm in the 13.56 MHz frequency band, for example, in accordance with the ISO / IEC14443 standard.

When the NFC function of the mobile communication terminal 30 is turned on, the NFC interface 38 periodically transmits an RF signal to search for an RF field. If the passenger moves the mobile communication terminal 30 to the NFC tag 20 of the taxi 10 When the RF field due to electromagnetic induction generated between the antenna 27 of the NFC tag 20 and the antenna included in the NFC interface 38 of the mobile communication terminal 30 is detected, Lt; RTI ID = 0.0 > NFC < / RTI >

A communication between the NFC interface 38 and the NFC tag 20 is divided into three types (NFC-A, NFC-B, and NFC-F) according to a data decoding method. Delay decryption) is a method of recording 0 or 1 as the difference between amplitude modulation of 0 and 100% amplitude modulation. NFC-B similarly records 0 or 1 with a variation of% amplitude, where amplitude modulation is 10 And the amplitude modulation value changes from low to high, as opposed to NFC-A. The NFC-F is originally manufactured by Sony Corporation (FeliCa) electronic payment NFC card. The signal encrypted in this way is fast and widely used for subway tickets, credit card payment, identification, etc. In the present invention, any of the above-described methods may be used.

The communication unit 40 is responsible for the wireless communication function inherent to the mobile communication terminal 30 and transmits data of the NFC tag 20 read by the NFC interface 38 to the server 30, Or to send the position information read by the position sensing unit 42 to the server system 100.

The position sensing unit 42 includes a Global Positioning System (GPS) receiver, for example, to confirm the position of a user who has boarded the taxi 10 and to confirm the travel path of the taxi 10 .

The data structure that may be used in the implementation of the present invention will now be described with reference to FIG.

In the NFC tag 20, "UID" data indicating the serial number of the NFC tag is stored.

The data used by the app of the mobile communication terminal 30 includes latitude (GPS latitude coordinates), longitude (GSP longitude coordinates), vehicle ID (representative number of the vehicle), user ID (user identification number) Information used when paying the fee).

 The vehicle information data includes a vehicle ID (a number representing a vehicle), a vehicle number, a UID (NFC tag serial number), vehicle status information (information indicating whether the vehicle is a stolen vehicle or an ineligible vehicle) ), Vehicle usage information (kindness of a taxi driver, service status, customer satisfaction, rating, etc.), and other necessary information (information such as vehicle type, color, yearly model, taxi company, and contact information).

The user registration data includes user identification (user name, passenger, taxi company), user ID (user name), password, telephone number (phone number of the mobile communication terminal), secret key Report), and other necessary information.

5, an overall process of an information processing system and method according to an embodiment of the present invention will be described.

In FIG. 5, steps 202 to 206 show a procedure in which a taxi company and a passenger register a user to use the information system according to the present invention, and a taxi company (an article in the case of a private taxi) .

First, in step 202, the taxi company 10A registers the car / vehicle in the web server 130. [ The data required to register the car / vehicle are the vehicle ID, the car number, the car registration number, and the car loan ID. The taxi company 10A may register the greeting. The Web server 130 stores this information in the user information server 140. In the case of a private taxi, 10A is labeled "Article / Taxi Company" because the article is the same as the taxi company.

When the vehicle is lost or stolen, the taxi company 10A registers the stolen vehicle in the user information server 140 (step 204). Meanwhile, the server system ('100' in FIG. 1) or the user information server 140 according to the present invention can fetch stolen vehicle information in association with the police database. This information can be stored as the vehicle status information of the "vehicle information data structure" shown in Fig.

In order to use the present invention, the passenger sends the user registration to the Web server 130 via the mobile communication terminal 30 or an information processing device such as a computer at step 206 and stores this information in the user information server 140 do. The user registration of the passenger requires data represented by "user registration data structure" in Fig.

When the passenger uses a specific taxi, the mobile communication terminal 30 is brought to the NFC tag 20 to request tag information (step 208). The mobile communication terminal 30 that has read the tag information encrypts it, sends it to the vehicle information server 120, and requests the vehicle inquiry. The vehicle information server 120 decrypts the encrypted tag information (tag sequence information) received from the mobile communication terminal 30, inquires about whether the vehicle is normal based on the information, encrypts the result, and transmits the encrypted result to the mobile communication terminal 30 (Step 210). The encrypted result is decrypted by the mobile communication terminal 30 and displayed on the screen display unit 34. A symmetric key algorithm can be used for encryption / decryption of the mobile communication terminal 30 and decryption / encryption of the vehicle information server 120. [ According to an embodiment of the present invention, the telephone number of the mobile communication terminal 30 is used as the encryption / decryption key value of the symmetric key algorithm.

When the result received by the mobile communication terminal 30 is normal in step 210, the passenger boarded the taxi, registers the vehicle on the vehicle information server 120 through the mobile communication terminal 20 (step 212) And registers it with the vehicle information server 120 automatically (step 214). Therefore, the vehicle information server 120 can know which cab is occupied by which passenger. Although not shown in the figure, the fact that the vehicle information server 120 or the SNS server 160 notifies the taxi driver that the passenger is riding and the taxi company also informs the taxi driver of this fact.

Upon reaching the destination, the passenger pays transportation expenses and registers the payment details in the vehicle information server 120 (step 215). Here, payment details do not include the amount of money that the passenger paid for transportation in cash. In the present invention, payment of transportation expenses refers to a mobile Internet payment method, for example, a deferred payment method can be used.

If an accident occurs during the movement of the taxi or if the taxi moves on a completely different path from the destination, the passenger informs the vehicle information server 120 of the emergency situation by pressing the emergency button displayed on the application of the mobile communication terminal 30 ). The vehicle information server 120 delivers this information to the SMS server 160. [ The SMS server 160 notifies the passenger of the emergency situation by sending a short text message to a predetermined destination of the passenger, and also sends a warning message to the registered article mobile phone. Meanwhile, the server system ('100' in FIG. 1) of the present invention may be interlocked with the police server to inform the police agency that the SMS server 160 is in an emergency situation.

The processing performed in step 218 will be described later.

5, the server is divided into the vehicle information server 120, the web server 130, the user information server 140, the payment server 150, and the SMS server 160, . Therefore, all the servers of FIG. 5 may be included in the server system 100 shown in FIG. 1, and the servers other than the vehicle information server 120 may be physically separated from the server system 100 of FIG.

FIG. 6 is a flowchart illustrating a process for determining whether a taxi is normal by using NFC information according to an exemplary embodiment of the present invention. Referring to FIG.

First, the passenger moves the mobile communication terminal 30 to the NFC tag 20 attached to the taxi 10 (step 220). The mobile communication terminal 30 extracts the tag information (tag serial number) from the NFC tag 20 (step 224) and encrypts it. The encrypted tag information is transmitted to the server ('100' in FIG. 1 or '120' in FIG. 6) by the mobile communication terminal 30 and the server 100 decodes the tag information (step 226) Information is extracted (step 228). The extracted information is compared with the information stored in the database 110 to perform authentication (step 230). It is determined whether it is normal according to the authentication result (step 232). If it is normal, the taxi status information (for example, the information of FIG. 7A) indicating normal is sent to the mobile communication terminal 20, The status information is sent to the mobile communication terminal 20 (step 234) and reported (step 236).

6 shows an example of confirming whether or not the taxi is normal through the server 100. However, according to another embodiment of the present invention, whether or not the taxi is normal can be confirmed from the mobile communication terminal 30 Check yourself. This embodiment is intended to allow the passenger to check whether or not the taxi is normal even when the passenger is in a poor communication state or in an area where communication is not smooth, such as an outline, (collectively referred to as a 'shadow area'). To this end, the mobile communication terminal 30 switches to the self-checking mode when communication is not possible for a certain period of time. In the self-checking mode, the mobile communication terminal 30 uses the black list information stored in its own memory (35 in FIG. 3) to determine whether a taxi to be boarded is normal.

The black list information may be composed of vehicle information reported as theft or lost vehicle in the vehicle status information (see "Vehicle Information Data Structure" in Fig. 4) stored in the vehicle information server 120. [ It is desirable to minimize the data amount of the black list information. For example, the black list information is constituted by only the tag serial number of the NFC tag issued by the operator of the server system 100 and the value indicating whether the vehicle corresponding to the NFC tag is registered in the black list. The reason why the data amount of the black list information is minimized is that the mobile communication terminal 30 must continuously update the information from the server 100 in order to keep the black list information as the latest information. However, when the data amount of the black list information is large, Since the terminal 30 must receive a large amount of data, the communication use fee may increase and the server 100 may also be subjected to a heavy load.

The process of the passenger requesting the black list information to the vehicle information server 120 through the mobile communication terminal 30 and storing and updating the received black list information in the own memory of the mobile communication terminal 30 is similar to that shown in step 218 of FIG. same.

In order to prevent excessive use of mobile data due to frequent updating of the black list information, it is desirable to set the mobile communication terminal 30 to update the black list data only when the passenger is out of the usual traveling position. In addition, the determination as to whether or not the taxi is normal through the black list is in contrast to the case where the mobile communication terminal 30 is located in the shaded area, and since the taxi through the server 100 is not normal, It is preferable to clearly notify.

7A and 7B are diagrams of an application screen according to the present invention.

When the passenger approaches the NFC tag 20 of the taxi 10 by detecting the RF field, the app automatically operates. When the mobile communication terminal 30 reads the information of the NFC tag 20 and receives information on the normal state of the taxi from the server 100, the contents thereof are displayed on the screen as shown in FIG. 7A.

The app screen 300 shown in FIG. 7A shows a case where the taxi is normal. The screen includes a car number display unit 302, a car type display unit 304, a color display unit 306, a driver display unit 308, and a rating display unit 310 Lt; / RTI > Below it, there are a vehicle normal display unit 320, an advertisement display unit 330, and a riding / declaring button 340 indicating whether the vehicle is normal or not. At the bottom, a fixed display portion can be placed and a menu 350, an emergency button 360, and a setting 370 function portion can be placed.

When the cab mounted on the passenger is normal, the vehicle normal display unit 320 displays a message such as " normally registered vehicle ", and if abnormal, displays a message such as "abnormal vehicle ". The riding / return button 340 displays only the riding button when the vehicle is normal, and only the report button when it is abnormal.

The taxi to be used by the passenger is normal and the passenger pushes the riding button 340, the screen 301 shown in Fig. 7B can be displayed through the menu button 360. [ The passenger can register his / her current location and confirm the travel route through the location registration / view 380, pay the taxi fare through the transportation expenses settlement 385, And articles.

However, if the mobile communication terminal 30 does not have the NFC function or has the NFC function but is in the inactive state at the moment of boarding the taxi, The present invention can be applied.

Dimensional code 19 is printed on the surface of the upper layer 22 of the NFC tag 20 as described with reference to FIG. The two-dimensional code 19 is information recorded in both the horizontal and vertical directions, and can be implemented by a QR code developed by Denso Wave. Two-dimensional codes can significantly increase the amount of information that can be recorded compared to conventional bar codes, can be recognized at high speed in any direction, and can restore up to about 30% of the data even if part of the recorded code is damaged .

In the embodiment of the present invention, only the tag serial number data of the NFC tag 20 is recorded in the two-dimensional code 19. When recording only such a small amount of data, not only the two-dimensional code 19 is necessarily available, but it is also possible to record the bar code in the NFC tag 20.

On the other hand, it is preferable to apply a hologram or an optical water-meter technique to prevent unauthorized copying or forgery of the code regardless of whether the two-dimensional code 19 is recorded in the NFC tag 20 or the bar code is recorded.

The two-dimensional code 19 is read through the camera 37 of the mobile communication terminal 30. The processing of the data thus read is performed through the NFC interface 38 of the mobile communication terminal 30 described above, The description will be omitted since it is not different.

On the other hand, when the NFC function and the two-dimensional code recognition function are not both operated by the mobile communication terminal 30, the passenger directly inputs the vehicle number through the keypad or the user interface 36 of the mobile communication terminal 30, To the information server 120 so as to check whether the vehicle is normal or not. In this case, however, the security of the passenger can not be guaranteed because the server system 120 can not know the NFC tag information of the taxi.
