DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be further described below with reference to the drawings. FIG. 1 shows an outline of an electronic commerce system according to the present invention. In this example, the Internet 1 spread all over the world as a computer network is used as a backbone of communication means. This Internet 1 has a server system 10 which is the core of a commercial transaction system.
Is connected. Further, a subsystem 20 capable of transmitting and receiving information to and from the server system 10 is connected to the Internet 1. In the following, in order to describe this in more detail, the subsystem 20 is used to store stores distributed in regions, for example, POs of convenience stores.
The system is an S system, and the server system 10 is a computer system of the headquarters. Internet 1
Are connected to the public telephone network 3 through an appropriate gateway 2 such as a provider server, and ordinary users can directly connect to the Internet network 1 or connect to the server system 10 through the public telephone network 3. Can be accessed. A base station 4 is connected to the public telephone network 3, and the Internet network 1 can be accessed using a mobile phone 5. In a similar system, the Internet can be accessed by a portable terminal such as a PHS terminal, a PHS, or a PDA having a portable telephone function. In the following, a mobile phone will be described as a mobile terminal or a mobile terminal, but as described above, mobile type terminals that can be used in the present invention are not limited to mobile phones.

The head office server system 10 has various functions such as a mail server and a WWW server. FIG. 1 shows a schematic configuration of a portion related to the present invention. The server system 10 includes a gateway server 11 for connecting to the Internet 1,
A PS server 12 is provided. The GPS server 12 has a function of determining a current location of a caller based on position information transmitted from a mobile terminal such as a mobile phone. If the mobile phone is equipped with a system that can perform satellite positioning by receiving radio waves from GPS satellites, the current location of the mobile phone of the transmission source can be determined with extremely high accuracy from the information on the latitude and longitude obtained by the satellite positioning. In the case of a PHS terminal, the current location can be accurately determined from the CSID indicating the base station. Further, even with a mobile phone, a rough area can be determined from base station information.
The accuracy of a CDMA mobile phone is very high. In any case, the GPS server 12 knows the current location of the caller, so that it is possible to determine whether or not there is a store or other facility closest to the user who owns the mobile phone 5.

The server system 10 further includes an event information database 16 and a user information database 17
It has. The event information database 16 records information for executing an event, such as the presence or absence of a campaign such as a discount service, a discount rate, a discounted product, and conditions of a target person to provide the service. The user information database 17 records information such as the name, member number, address, telephone number, age, date of birth, occupation, annual income, hobbies / hobbies, and family structure of the registered user. .

The server system 10 is a system based on the information of these databases 16 and 17, and includes an authorization server 13 for issuing a user a right to receive a service such as a discount, an authentication server 14 for authenticating the issued right. And a server 15 for updating information in the user information database 17 with information obtained in the process of issuing or authenticating. When the user accesses the authorization server 13 via the mobile phone 5, the authorization server 13 shows the list of services that are recognized by the user and that can be provided at a store near the user. Then, when the user selects one or more of them, a page including identification information indicating approval is displayed. The user downloads the page including the identification information to the mobile phone 5 and shows the identification information at the store 20 to receive the service. At this time, the POS system of the store 20 requests the authentication server 14 to authenticate the identification information via the Internet 1. At this time, the contents, time and place of the service that the user intends to receive are known, and the information is stored in the user information database 1 by the updater server 15.
7 is reflected.

Further, in the server system 10 of the present embodiment, the identification information is provided by a bar code. That is, the authorization server 13 is set so that the user downloads it.
Contains a bar code serving as identification information, and the bar code allows a member number, an approved service, for example, a discounted product, a discount rate, and the like to be known. In the POS system of the store 20, information is automatically referred to the server system 10 of the headquarters by reading the barcode displayed on the screen 5a of the mobile phone 5 with a barcode reader. As a result, the identification information is authenticated, a service can be provided to the user, and the user information is stored in the server system of the headquarters.

In the service system 8 using the barcode of the present embodiment configured as described above, information indicating the right of the user to receive the service is displayed by the barcode, and furthermore, the information is displayed on the mobile phone 5 and, of course, other Is provided as information that can be downloaded including mobile terminals. Therefore, the user can present the information to the service provider by displaying the information on the screen 5a of the mobile phone, and the provider provides a POS called a barcode reader.
The identification information can be input using hardware normally provided as a system. Therefore, in the e-commerce system 8, the hardware resources of the user and the store can be effectively used, and the user or the staff of the store does not need to manually copy or print out the information. Further, it is possible to distribute the information in a short time, such as by downloading the identification information via a communication means such as the Internet and uploading the usage form.

FIG. 2 is a flowchart showing an outline of the issuance and authentication processing in the server system 10. First, in step 31, when there is an access from the user's mobile phone 5 via the public telephone network 3 and the Internet 1 for providing services such as discount information, the gateway server 11 accepts the access, and the authorization server 13 proceeds to step 32. Determine whether the corresponding service can be provided. At this time, when the information on the current location is needed, the current location of the user is acquired from the GPS server 12. If an appropriate service is available and can be provided to the user, in step 33,
The identification information including the member number is converted into a bar code, and a page including the identification information is displayed. At the same time, data relating to the issued identification information is stored in the event information database 16 or the user information database 17. Of course, it is also possible to create a new database.
On the other hand, the user is authorized by downloading the page.

Next, at step 34, the information read by the bar code from the POS system of the store 20 is sent via the Internet 1 to the gateway server 11
Is received, the authentication server 14 checks the identification information in step 35 with the authorization information stored in the database 16 or 17. When the identification information can be confirmed, the store 20 is notified of the authentication in step 36. On the other hand, if the authentication cannot be performed, an error occurs in step 37, and the provision of the service is denied. Further, in step 38,
The information transmitted from the store 20 is recognized as new information of the user by the update server 15, and the user information database 17 is updated.

As described above, in the commercial transaction method of the present embodiment, the step of authorizing the right to receive the service, the step of approving the same, and the step of updating the user information obtained accordingly are performed by the server system 10. Built inside. Further, the commercial transaction method according to the above-described flowchart is provided as a program including instructions capable of executing the respective steps, which is recorded on an appropriate recording medium readable by a computer (server) such as a magnetic disk and a CD-ROM. Can be. Further, in the server system 10, it can be stored in a storage device together with other programs and the like, and can be downloaded to an appropriate machine and executed.

In the commercial transaction method of the present embodiment, the information to be authorized is issued via the Internet, and the authentication process is also performed via the Internet. Therefore, the time loss in transmitting information is minimized. Further, since a barcode that can read information easily at an end input terminal, that is, a POS system of a store, is used, the time required for inputting and outputting information is minimal and there is no mistake. Therefore, the service desired by the user can be reliably provided without delay, and the user is fed back without delay. Therefore, a high quality service can be provided to the user, and further improvement of the service can be aimed at.

In the following, the transaction system and method according to the present invention will be further described based on some specific examples. FIG. 3 shows an example in which the present invention is applied to a system that issues a discount coupon at a convenience store and receives the service. First, the user uses the mobile phone 5 to operate the server 10 at the headquarters of the convenience store.
Access and register as a member. Usually, this step or processing 51 is performed by a user accessing a homepage provided by the WWW server of the server system 10. In the member step 51, information considered to be important for providing services at convenience stores, such as name, member number, address, telephone number, age, date of birth, occupation, hobby, and family structure, is stored in the server 10 in advance. Registered in. Therefore, in the server system 10, the processing 5 for storing the personal history based on the member information is performed.
2 is performed. That is, the access history on the server and the history of the actual purchase at the store are accumulated and updated for each member. Further, in the server system 10, a campaign is formed based on the member information, and processing 5 for registering the content of the campaign in the server is performed.
3 is performed. The registered contents are discounted products, discount rates,
The conditions of the target person, etc. Further, the content of the campaign is provided to the user using a homepage or the like.

When the user wants to receive the service, the user accesses the discount information of the server system 10 using the mobile phone 5 (step 54). At this time, the member number, position information, and the like are provided to the server system 10 at the same time. These pieces of information may be manually input by the user, or, as described above, the server 10 may call the mobile phone's caller ID,
It may be automatically obtained from GPS information or the like.

When there is access, the server system 10 next searches for member information from the member number of the accessed member in step 55, and searches for a matching campaign together with location information. In the process, when a plurality of services can be provided, a selection page 65 as shown in FIG. 4A can be displayed to allow the user to select. When the service to be provided is determined, the server system 10 transmits a coupon ticket page 66 as shown in FIG. The page 66 includes a barcode 67 serving as identification information, and a barcode 6
7 includes information such as a member number, a discount product, and a discount rate. When the user wants to receive the offered service,
Copy the coupon page sent in step 56 to mobile phone 5
To download.

In this way, the right to receive the discount is obtained, and when the user actually purchases a product at the convenience store 20, the user selects the mobile phone 5 at step 57.
Of the obtained coupon is displayed on the screen 5a of the user. Store 20
The staff reads the barcode 67 displayed on the screen 5a of the mobile phone 5 with the barcode reader 21 in step 58. The POS system automatically queries the server system 10 via the network at step 59 for information such as the member number, the discounted product, and the discount rate read from the barcode 67. As a result, in the server system 10, the use history of the coupon issued in step 60 is stored as user information, and the identification information is authenticated in the POS system of the store 20 in step 61. Therefore, the user can receive the discount service corresponding to the coupon at the store 20 in step 62.

In the example shown in FIG. 5, the system according to the present invention is applied to reservation for attending a conference.
In step 71, the user accesses the server system 10 via the network using the mobile phone 5 and applies for attending a pay conference. At this time, information relating to the user such as a name, an address, a telephone number, a credit card number, an occupation, and a name of a conference to attend is also registered in the server system 10. In step 72, the server system 10 deducts the fee in accordance with the application for attendance, and registers the user information in the attendee list. In step 73, the fact that the attendance has been accepted is displayed on the portable terminal 5 via the network. Further, on the reception display screen, identification information indicating that the right to attend the conference has been given is displayed as a barcode 67. The barcode 67 includes information necessary for authentication, such as a name, an address, a telephone number, an occupation, the name of a conference to attend, and the date and time of application reception. The user can use this bar code 67
Is downloaded to the portable terminal 5 in step 74.

When attending the conference, the user displays the downloaded confirmation table on the liquid crystal display screen 5a of the portable terminal 5 in step 75. In the reception 23 of the conference, in step 76, the staff reads the barcode 67 displayed on the display screen 5a by the barcode reader. The input terminal of the reception 23 is connected to the server system 10 via a network such as the Internet or an in-house LAN. In step 77, the information of the barcode read by the barcode reader 21 and the target user Is transmitted to the server system 10 as attendance information. In response,
In the server system 10, in step 78, the actual attendance status of the applicant is managed as a history, and the database of the applicant (user) is updated. At the same time, in step 79, the information of the barcode 67 is authenticated, and the information is returned to the reception 23.

Accordingly, the reception 23 authenticates the identification information presented by the user on the mobile phone 5, and permits entry to the conference in step 80. As described above, in the conference attendance reservation system using the portable terminal of this example, the attendance reservation can be easily made via the network, and the fact that the attendance reservation has been made can be indicated by the bar code on the screen of the cellular phone. By displaying a screen including 67, it can be presented to the receptionist. Therefore, there is no need to wait for the confirmation table to be mailed or to output the confirmation table on a printer. Furthermore, since there is no confirmation table, there is no situation in which the headquarters is called at the reception to check whether there is an application. Also, the reception staff does not need to visually check the numbers on the confirmation table with the ledger, etc., and can surely confirm the attendees in a short time. At the same time, user information such as attendance information can be sent to the server system 10,
History about the user can be accumulated.

Also, in the present system, a bar code is used as a form for displaying the identification information. The barcode is digital information that can be read by a partner by displaying it on a screen, and can be easily input by a general-purpose means called a barcode reader.
Further, since the input can be performed in a non-contact manner, the screen is not damaged, and the data or the medium for outputting the data is not deteriorated. Therefore, it is possible to provide a system which supplies and recognizes identification information with extremely high reliability and safely. Further, as described above, information can be distributed without loss of time by supplying identification information through a network and performing authentication.

In the example shown in FIG. 6, the system according to the present invention is applied to a system for accumulating points, that is, a so-called point card service. In step 81, the user accesses the server system 10 via the network using the mobile phone 5, and registers personal information in advance to receive the privilege of the reward card. The information to be registered includes a name, a member number, an address, a telephone number, an age, a date of birth, an occupation, an annual income, a hobby / hobby, a family structure, and the like. The server system 10 performs a member registration in step 82 in accordance with the user's application, stores the member number, and stores a point card member list (database).
Register the user in. Further, the server system 10
In step 83, the membership card screen 68 is sent to the portable terminal 5 to inform the user of the acceptance of the membership registration via the network. At this time, on the membership card screen 68, identification information indicating that the user is a point card member is displayed as a barcode 67. The barcode 67 includes information necessary for authentication, such as a member number and an application reception date. Accordingly, the user downloads the reported point card screen 68 to the mobile phone 5 in step 84.

When the service of the point card is received, in step 85, the screen 68 of the downloaded point card is displayed on the screen 5a of the mobile phone 5 at the cash register 24 of the store. Then, at step 86, cash register 2
The staff member No. 4 reads the barcode 67 displayed on the screen 5a of the mobile phone by the barcode reader. The input terminal of the cash register 24 is connected to the server system 10 via a network similarly to the above-described system, and the input bar-coded information is sent to the server system 10 in step 87. At the same time, information such as point adjustment according to purchase, store code, purchase date and time, purchase item, and the like are sent to the server system 10 together with the member number and the like. In step 88, in the server system 10, the contents of the member information database are updated, and the authentication relating to the point service is returned to the input terminal of the cashier 24 in step 89. As a result, in step 90, the user can receive services such as point discount.

As described above, the commercial transaction system and method according to the present invention can be applied to services conventionally provided based on cards. Further, in the present invention, since the identification information is displayed by a bar code which can be displayed on a screen and can be read in a non-contact manner, a function replacing the card can be provided on the screen of the mobile phone. Therefore, when receiving a plurality of services, it is possible to save the trouble of carrying a plurality of cards prepared for each service. For example, the commerce system and method of the present invention can be applied not only to a point card but also to services such as a prepaid card and a credit card settlement, and can receive these services simply by carrying one mobile phone. Becomes possible.

In some cases, such as a credit card settlement, personal authentication is further required, but this is the same as the service form required to carry a card. That is, after the barcode displayed on the screen of the mobile phone is read and the identification information is authenticated, it is possible to further add information indicating the identity of the user by using a fingerprint, a password, or a signature. .

In the above description, the mobile phone is described as an example of the mobile terminal, but it is not limited to the mobile phone as described above. Further, the screen including the bar-coded identification information can be stored in the memory of the mobile phone. However, each time the information is needed, the screen is accessed by accessing the server system via the Internet. Can be displayed at the same time, and the load on the memory of the mobile terminal can be reduced. Further, when accessing the server system and displaying the screen, it is possible to increase the security of the identification information displayed on the mobile phone by inputting information that recognizes an individual such as a personal identification number.

As a form of displaying or outputting the identification information, it is possible to use a code other than a barcode, output information by voice, or use an infrared interface. However, considering the current hardware of mobile phones and hardware provided at POS such as stores, barcodes are the most suitable digital information that can be displayed on the screen and read without contact. ing. That is, each of the above-mentioned systems is compatible with the current mobile phone and other mobile terminals,
It can be realized by a combination of POS registers,
Resources owned by the user and the store can be used as they are.

It is also possible to construct a system in which voice information or the like is transmitted by bar codes instead of identification information, and the displayed information is reproduced by an appropriate device. However, the density of information that can be provided in a displayable form such as a barcode is low, and the display screen of the mobile terminal is not so large. Therefore, in this system, it is useful to transmit important information which is a small amount of information but is a key to receiving a service, and it is most desirable to provide the above-mentioned user identification information.

[0045]

As described above, in the electronic commerce system and method according to the present invention, a bar code indicating the right to receive discount coupons and various services is displayed on the display screen of a mobile terminal such as a mobile phone. A screen including the identified identification information is displayed through the network. Thereby, the user can transmit the information for receiving the desired service to the clerk in a contactless manner. Furthermore, in addition to providing services such as discounts to users, it is possible to collect information obtained by reading barcodes and accompanying information on a server and manage them as customer information, thereby providing higher quality services. Can be improved.
