<Technology field>

The present invention relates to a business model using a mobile terminal. The user of the mobile terminal transmits predetermined data to the server through the base station, and the server, which has built up the database, provides the mobile terminal with available content according to a predetermined rule. Economical benefits are realized through two-way data transmission and reception between the mobile terminal and the server.

<Problems with Prior Art>

Consumers want to buy things cheaper, and sellers want more consumers to buy their goods. Based on these characteristics between consumers and sellers, what is popular today is discount coupons. When a consumer purchases an item, he or she presents a pre-issued discount coupon to receive a discount of a certain size. However, because so many discount coupons exist in the market and are distributed online or offline, it is difficult for consumers to use the desired discount coupon at the desired time and place in the overflowing discount coupons. The present invention seeks to solve this problem by presenting a new business model using a mobile terminal. However, there are limitations to current services that transmit and receive data through mobile terminals and use content. Since the present invention can be achieved only by overcoming the limitations, the mobile service environment will be described first. .

With the increase of Internet users and the development of related technologies, various multimedia contents as well as simple text-oriented data are widely processed on the web. Today, a great deal of data and its contents are exchanged and sold over the Internet. From the point of view of the information provider, a database should be built to store the content, and the database should be made accessible to the consumer. From the point of view of the information consumer, it is necessary to know where the desired content is located and want to be able to obtain only the desired information easily and quickly.

As schematically shown in FIG. 1, the needs of such information providers and information consumers have been met via the Internet 2. The information consumer can access the information provider's website by simply entering a URL through the computer terminal 1 or by clicking a link in which the URL is recorded, and the information provider's server 3 stores Data can be quickly transmitted to the computer terminal 1 on the web. At this time, the consumer knows the URL of the information provider in advance or finds the location of the information provider by using an Internet search.

However, such an internet network 2 has a problem of lack of instantaneous or concurrency. There is a great deal of information on the Internet, and there are countless Web sites that provide it. However, in general, since the content desired by the user is very specific, for example, a trailer of a certain movie, the user has to go through a search process in order to obtain the desired content through the Internet.

In other words, in order to obtain that specific information from the Internet, it is necessary to access an Internet site where other information is published together on a large scale. There is also a problem in that the user must retrieve the specific information from a large database. For example, in order to know the existence of discount coupons, coupon codes, and how to use the discount coupons, a user must find an Internet site that provides the information, and also create numerous movie databases for that site. You must search and use a certain amount of time.

 In addition, the Internet is very lacking in mobility. Since the Internet requires a computer terminal 1 for network connection, there is a problem that a mobile user cannot use it easily.

The cellular network is an effective system for transmitting data to mobile terminals. Simple text or multimedia content may be transmitted to the mobile terminal via the base station. The commercialization of High Speed Downlink Packing Access (HSDPA), the 3.5th generation communication method, and the spread of so-called HSDPA phones have established a technological environment that can receive multimedia content. In this network, it is important to establish a server with a database of content to be sent to the mobile station and how the mobile station will specify a request for transmission of that content to the server. That is, the mobile station should be able to easily transmit the location information of the desired content to the server side, and the server should have already built a database for the content. However, it is very difficult for the mobile station to easily acquire location information about the content.

In addition, in the case of a mobile terminal, a user interface is vulnerable because there is no keyboard or mouse such as a laptop or a PC and the display is small. Therefore, it is not easy to search for information or to prepare and transmit a request signal. As a result, a means or method for simplifying an input task is a key element in a technical field or a business model based on receiving and playing content using a mobile terminal.

That is, the method of using the content using the cellular network has the advantage that the user can use the mobile, but there is a fatal problem that the consumer cannot easily access the content. Therefore, consumers cannot easily grasp where the content is located, and even if they know the location, there is a limit that they cannot use the content quickly and easily. This is because the consumer does not know whether the desired content exists and should search the content even if he / she knows it, and the user interface for doing this is vulnerable.

Therefore, conventionally, it is not easy to obtain a 'desired' discount coupon or obtain information on the discount coupon, and it is not easy to know in which place the obtained discount coupon should be used. In addition, when using the discount coupon, it was not easy to use the discount coupon immediately at the desired time and place at the desired place. In order to solve this problem, even when using the Internet or a mobile terminal, there were limitations due to problems of mobility, instantaneousness, and user interface in the conventional manner.

It is a first object of the present invention to provide a system and method which provides substantial economic benefits and convenience to consumers by allowing more discount coupons to be distributed and used, while giving sellers more sales opportunities.

The second object of the present invention is to allow a subscriber to obtain the desired discount coupon at any time and anywhere with the subscriber's own mobile terminal wherever the discount coupon is associated with the discount coupon. The present invention provides a system and method for immediately transmitting detailed information to a user of a mobile terminal. Wherever the discount coupon exists (whether online or offline), the consumer can obtain it immediately, eliminating the need for cumbersome searching.

It is a third object of the present invention to provide an environment in which coupons can be easily used by allowing the coupons and stores in which the coupons can be used are directly related to each other.

On the other hand, other unspecified objects of the present invention will be further considered within the range that can be easily inferred from the following detailed description and effects.

In order to achieve the above object, as a first aspect of the present invention, N (N is an integer greater than 1) having a coupon code and a store code printed in a two-dimensional code pattern, and a two-dimensional code pattern area in which the coupon code is printed. ) A coupon, a store medium having a predetermined location within a store, and having a two-dimensional code pattern area on which the store code is printed, the coupon code printed on the coupon, and the store code printed on the store medium.

And transmitting, by the server, the coupon content or the advertisement content corresponding to the corresponding coupon code to the mobile terminal.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the following description of the present invention, when it is determined that the subject matter of the present invention may be unnecessarily obscured by those skilled in the art such as related well-known functions, the detailed description thereof will be omitted.

2 schematically shows an example of the overall configuration of a system according to the present invention. The pattern of the two-dimensional code 101 is printed on the coupon 100, and after reading the two-dimensional code 101 of the coupon through the digital camera 11 provided in the mobile terminal 10, the reading process is performed. The code information read through the base station (included in the mobile communication network 20) is transmitted to the server. Server 30 has a plurality of databases. DB1 (32) is a coupon database that stores the data about the coupon, DB2 (33) is a personal database that stores the code information of the coupon to be sent for each individual, DB3 (34) can use the coupon Seller database that stores and sorts by seller. On the other hand, Commercial DB (31) means a database that stores the advertising information for transmission to the subscriber, and may or may not be utilized depending on the service application. In addition, a log database, a member database, etc. necessary for the system configuration of the server 30 are not shown.

In the system of the present invention, the user is closest to the coupon because the two-dimensional code must be photographed with the digital camera embedded in the mobile terminal 10. In general, when a user is in close proximity to a coupon, the user desires to obtain immediate information about the coupon immediately, or desires a kind of 'archive action' for later use of the coupon. In the present invention, such a desire can be satisfied only by photographing the two-dimensional code printed on the coupon by the user's mobile phone. For this purpose, DB1, DB2, DB3 on the server side will all or optionally be utilized.

3 schematically shows a relationship between the coupon 100 and the mobile terminal 10. It also means the relationship between the coupon 10 and the user who consumes the coupon. The user is very close to the coupon. In understanding the technical idea of the present invention, it is important to understand the relationship between the coupon and the user. On the other hand, the coupon 100 is distributed on-line and may be made of a material such as paper or plastic, or may be displayed on a computer monitor screen online. It should be emphasized that the two-dimensional code 101 is present in all coupons 100 used in the present invention.

  4 (a) and 4 (b) show examples of two-dimensional codes. The two-dimensional code pattern of the present invention stores a coupon code previously given, and adds that it may have various types and types.

The coupon has one or more two-dimensional code pattern areas printed with these two-dimensional code patterns. The two-dimensional code pattern area is created by printing the two-dimensional code pattern directly on the coupon, but is also formed by attaching the printed two-dimensional code pattern to a specific position of the coupon. For coupons offered online, the two-dimensional code will be displayed as an image file anywhere on the web page. In the claims of the present invention, all of these methods are expressed as 'printing'.

Now look at how the mobile terminal reads this two-dimensional code pattern. 5 shows a code reading section 15 having a memory 16 and a central processing unit 17, a display 60 for displaying image information (two-dimensional code), and a digital camera 11 for capturing image information. It is shown. That is, FIG. 5 shows the code reading unit 15 in the internal configuration of the cellular phone with the built-in digital camera. The memory 16 of the code reading unit 15 stores a two-dimensional code reading program 19 which performs a function of reading the image data 18 and the two-dimensional code input through the digital camera 11. The CPU 17 controls the two-dimensional code reading program 19 to perform two-dimensional code image processing in accordance with this program. The two-dimensional code reading program 19 includes a module for reading image data of a captured two-dimensional code pattern, and a module for recognizing a coupon code of the corresponding image data.

6 shows an example of a schematic overall system of a business model according to the present invention. This system can be divided into three areas. The first area I is an area for capturing the unique coupon code of the coupon to the mobile terminal 10 and transmitting it to the server. The second area II is an area for capturing a unique shop code of a shop and transmitting the same to the same mobile terminal 10 to a server. The third area III is an area in which the server reads the data value transmitted from the server to the same mobile terminal 10 and uses the coupon. First, the overall system will be described with reference to FIG. 6, and then the process of each region will be described in more detail.

The coupon code 101 is printed on the coupon 100 in the form of a two-dimensional code. This coupon code 101 is unique to each coupon. ① When the user of the mobile terminal 10 captures the coupon code 101 by using the digital camera of the mobile terminal, the coupon code data is automatically or manually transmitted to the server 30 according to a predetermined procedure, and the server 30 ) Stores the corresponding coupon code data in the personalization DB2 (33). In other words, the user has the same effect as having the coupon code directly by photographing the coupon code with his mobile phone. In addition, while repeating the above-described coupon capture action, the user can store many coupons on the server side.

Next, we will look at how to use the coupon. The user will visit the store to purchase the item. The store also has a unique coupon code 201 (defined as "store code") printed in a two-dimensional code format, which is printed on the store medium 200 and provided to the customer. ② The user of the mobile terminal 10 as a customer transmits the store code data to the server 30 automatically or manually by capturing the store code using the digital camera of the mobile terminal. The server checks the existence of data corresponding to the corresponding store code data in the DB3 34, and then searches the DB2 33 to check whether the user has a coupon code corresponding to the store code data. ③ If a corresponding coupon code exists, the server 30 transmits the data identifying the same to the mobile terminal 10. This identification data is displayed on the screen of the mobile terminal 10 and may be a one-dimensional barcode image file. When making a calculation after purchasing an item in the store, the user shows the one-dimensional barcode image file received from the server 30, and the clerk reads the image file using the store's reader 300 to obtain the coupon. Will be used. This reader 300 may be understood as a general purpose reader that is usually used when calculating things in supermarkets. ④ When the coupon is used, the terminal 301 of the store sends an event that the coupon is used to the server 30, and the server 30 updates the DB2 (33). Such a general system of the present invention will be described in more detail.

Of the first area Example >

Figure 7 shows an embodiment of the first region of the system of the present invention. The user of the mobile terminal 10 is a mobile station subscriber of the mobile communication company, and also needs to register in advance as a member of the system in order to use the service provided by the server 30. When the mobile terminal 10 captures the coupon code 101 of the coupon 100 using a digital camera, the two-dimensional code reading program 19 reads the image data of the captured two-dimensional code pattern to obtain the coupon code data. Extract. The coupon code data is automatically or manually transmitted to the server 30. When the captured image data is read as the coupon code 101 of the two-dimensional code, the terminal may automatically transmit the coupon code data to the server by an application program stored in the memory. Alternatively, the user may be asked whether to transmit to the server via the terminal display, and if the user enters "Yes", the user may transmit to the server. The server 30 stores the received coupon code data in the DB2 33.

 DB2 33 is uniquely classified for each member, and has a table for effectively storing and managing coupon code data. This table may include all or part of the serial number for identification, the issue number of the coupon, the issuer, the discount rate, the year of issue, the expiration date, the rules for using the coupon and the product information used. The user has the same effect as having the coupon code directly by photographing the coupon code with his mobile phone. In addition, while repeating the above-described coupon capture action, the user can store many coupons in DB2 33 on the server side.

In some embodiments, the server 30 extracts the coupon content corresponding to the coupon code received from the mobile terminal 10 from the database 32 and transmits the coupon content to the mobile terminal 10. This coupon content informs you about the coupon. If the coupon content stored in the database 32 is a video file, the corresponding coupon content is streamed in real time through the display of the mobile terminal 10 requesting the transmission of the content. If the coupon content stored in the database 32 is text, it will be displayed on the screen of the mobile terminal 10 in a Short Message Service (SMS) manner. In another embodiment, the server 30 will extract the advertising content from the DB 31 and send the commercial advertising content to the mobile terminal 10. This advertising content can be an advertisement for any product that can use the coupon.

In order to transmit the content as described above, the server operator first produces content containing information related to the coupon. This content is a media file, and in order to stream it to a mobile terminal, it must be encoded into a streaming file by an encoder. In particular, it complies with the mobile standards so that media files can be streamed in mobile environments, and converts them into streaming files with the appropriate bitrate and size, codec, and file format. The encoded streaming file is stored in the media folder of the streaming server, and a link to the media is generated so that the terminal can access the streaming server to receive the streaming service. When the streaming request of the corresponding content is received from the mobile terminal, the streaming server streams the corresponding content to the mobile terminal through a transmission network such as a cellular network. In another embodiment, the content may be text, in which case a separate SMS server should be provided. At this time, the content is transmitted in the form of SMS (Short Message Service) rather than streaming.

Therefore, 'service data 1' shown in FIG. 7 means the coupon content and / or advertisement content.

Of the second area Example >

8 schematically illustrates a process that occurs while a customer mobile terminal 10 captures a store code 201 printed (or displayed) on a store medium 200 in a store that is a merchandise seller. The store medium 200 may be various, such as paper sheets, plastic sheets, walls, displays of electronic goods, and the like.

When the mobile terminal 10 captures the store code 201 using a digital camera, the two-dimensional code reading program of the mobile terminal reads the captured two-dimensional code pattern image data and extracts the coupon code data. The coupon code data is automatically or manually transmitted to the server. This procedure is the same as the process in which the mobile terminal captures the coupon code in the first area and transmits the coupon code data to the server. To this end, a database that uniquely classifies each store must be built in advance. The server checks the existence of data corresponding to the corresponding store code data in the DB3 34, and then searches the DB2 33 to confirm whether the user has a coupon code corresponding to the store code data.

The subscriber asks, "Is there any coupon that I can use in this store?" The system is provided with DB2 33 and DB3 34 to automatically resolve the subscriber's questions, and has a comparison table for effectively matching the data of DB2 33 and DB3 34. In addition, in order to effectively correspond with the coupon code and the store code, it is preferable that the data about the coupon code and the data about the store code stored in the database have a common identifier.

Of the third area Example >

If there is a corresponding coupon code, the server 30 transmits data identifying this to the mobile terminal 10 and is displayed on the screen of the mobile terminal 10. In FIG. 8, this identification mark data is indicated as 'service data 2'. This is like a conventional coupon. The service data 2 may be any one of text, one-dimensional barcode image file, and two-dimensional barcode image file. In the case of text, a store clerk has a inconvenience of inputting a text composed of a combination of letters and numbers into a store terminal. In the case of a 2D barcode image file, a separate 2D barcode reader is required for each store. However, since barcode readers used in stores today are generally one-dimensional barcode readers, it may be more useful if the service data 2 is a one-dimensional barcode image file. That is, when a store clerk makes a calculation, the coupon is conveniently used by proximity of the store's barcode reader to the one-dimensional barcode displayed on the screen of the mobile terminal, such as reading the barcode of the product to calculate the price of the purchased product. It becomes possible.

The use of the coupon generally means a discount of the price according to a predetermined ratio, but it is also possible to purchase goods at the economic monetary value of the coupon itself. For example, if A coupon is a 20% discount coupon applicable to "B children's clothing", 20% discount can be obtained when purchasing "B children's clothing". Also, for example, if the C coupon is a "10USD" coupon, the user may present the C coupon displayed on the mobile phone screen instead of paying 10USD. If a user has a large number of coupons stored in his or her database, points can be given for each coupon, and if the user has exceeded a certain point value, it can be used as a currency (payment method based on the total monetary value of the points). . This requires the creation and storage of certain rules that are agreed upon between the issuer of the coupon, the server operator, and the seller and made by software.

See FIG. The coupon is used by reading 'service data 2' through the store reader 300. The terminal 301 of the store transmits an event that the corresponding coupon is used to the server 30, and the server 30 updates the DB2 33. The personalization of the consumer (user) deletes the data so that it cannot be used again for the coupon used in DB2 (33). The server 30 records the fact that the coupon has been used.

Mobile services using the two-dimensional coupon code of the present invention, accessories, gifts, computers, clothing, toys, home fashion, shoes, books, sporting goods, office supplies, magazines, pets, travel goods, mobile phones, tickets, travel, Flowers, bags, golfing supplies, beauty supplies, health supplies, baby supplies, cosmetics, electronics, foodstuffs, etc. can be used in a wide variety and a wide variety.

On the other hand, the scope of protection of the present invention is not limited by the embodiments explicitly described above. In addition, it should be noted that the protection scope of the present invention may not be limited due to obvious changes or substitutions in the technical field to which the present invention belongs.

According to the present invention as described above, since the environment in which discount coupons can be distributed and used more is made, there is an advantage of providing more economic benefits to consumers and connecting more consumers to sellers.

According to the present invention, there is an advantage that the convenience of storage and use of the coupon is very high. You don't have to carry or store a lot of discount coupons yourself, you can store them automatically just by shooting the two-dimensional codes of the coupons. Coupons can be used.

In addition, since the present invention increases traffic for the use of wireless packets, the present invention will greatly contribute to the profit generation of mobile communication operators, and is a business model that can generate a lot of profits by being a useful means of various marketing activities and advertising activities.

Although effects not specifically mentioned in the specification of the present invention, it is added that the potential effects expected by the technical features of the present invention are treated as described in the specification of the present invention.
