Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. It is to be understood, however, that the embodiments described below are only for explanation of the embodiments of the present invention so that those skilled in the art can easily carry out the invention, It does not mean anything. In describing various embodiments of the present invention, the same reference numerals are used for components having the same technical characteristics.

1 is a schematic diagram of a product post management system using an ENF guarantee according to an embodiment of the present invention.

The product post management system using the ENF warranty includes the buyer terminal 100, the ENF tag 1000 and the authentication server 200 and includes a seller terminal 300 and one or more assurance manager servers 410, 420, As shown in FIG.

ENFG tag (1000) is generally manufactured at the time of product production, and product information including product name, product code, manufacturer, date of manufacture, distributor, country of manufacture, warranty period, can do. In addition, the NEFF tag 1000 can be manufactured in the form of a card or a sticker, and can be modified into various shapes and sizes.

The buyer terminal 100 and the seller terminal 300 can read the product information from the NEFF tag 1000 through the communication of the NFFC method and can read the card mode performed by the terminal having the normal NFC communication function, Write mode, and P2P mode.

Meanwhile, a general smartphone can be used for the buyer terminal 100 and the seller terminal 300, and can be applied to other devices capable of NFC communication at the level of ordinary technicians, and a dedicated application can be operated A mobile OS such as iOS or Android should be installed.

The authentication server 200 plays a role of overall management of the warranty service of the product, and more specifically, performs registration of the warranty service through product authentication, provision of quality related information, post warranty service brokerage, customer center service, marketing Can be performed. The detailed configuration of the authentication server 200 will be described in more detail with reference to FIG.

The authentication server 200 includes a database unit 210, an authentication unit 220, a guarantee management unit 230, and a control unit 240 for controlling these configurations.

The database unit 210 stores product information on a product providing a warranty service in association with a manufacturer server and information on a warranty service provider. Since the manufacturer separately creates the product information (product name, product code, manufacturer, date of manufacture, distributor, manufacturer, warranty period, warranty manager, etc.), the manufacturer stores the information in the database part 210 of the authentication server 200 So that the product information can be stored and managed from the authentication server 200 side. In addition to the product information, detailed information of the warranty manager, such as service center telephone number, location information, operating time information, contact person information, late information of other buyers, and service quality information, can be databaseed together.

The information stored in the database unit 210 is systematically classified based on a manufacturer, a brand name, and a product name, and can be searched and viewed through the buyer terminal 100 or the seller terminal 300, Do.

In addition, the database unit 210 stores a dedicated assurance management application related to authentication. The warranty management application may be an application created and distributed by the entity that operates the authentication server 200. The warranty management application may be a service for registering a warranty service through product authentication, providing quality related information, Provides a user interface (UI) that can be easily performed by the administrator.

On the other hand, since the type of the information stored in the NFC tag may differ from the kind of the information that can be recognized by the assurance management application or the authentication server 200, the form provided by the assurance management application and the processing provided by the authentication server 200 It may be generated as modified product information after the stored information of the NFC tag is read according to the easy-to-form format.

The authentication unit 220 issues an authentication number for the product information in association with the buyer terminal 100 and the seller terminal 300 and generates a key value unique to the product by combining the product code and the authentication number included in the product information do.

As already mentioned above, product registration and warranty service registration can be done easily through the NF-tag. More specifically, when the purchaser terminal 100 is tagged close to the NFC tag, the pre-installed warranty management application is activated and at the same time, the product information is generated according to the form provided by the warranty management application, 200 to the authentication unit 220. The authentication unit 220 combines the product code and the authentication number included in the product information after the authentication number verification process with the purchaser terminal 100 to obtain a key value unique to the product .

For example, if the product code is xxx-xxx-xxxx and the authentication number is oooo, the unique key value can be generated as xxx-xxx-xxxx-oooo. At this time, the generated unique key value is not overlapped with another number in association with the buyer and the product. Therefore, even if only the unique key value is confirmed in the future, it is possible to easily check what kind of product information and when a product is registered by a buyer by using a unique key value alone. These unique key values are encrypted and stored and transmitted for security purposes.

Meanwhile, the authentication number includes any one or more of numbers, letters, and special characters, and combinations of numbers, letters, and special characters can be used. Also, the authentication number conforms to the OTP (one time password) method. When a predetermined time elapses after the authentication unit 220 issues the authentication number, the authentication number is not a valid authentication number.

Accordingly, if the authentication number transmitted from the purchaser terminal 100 is not the same as the issued authentication number, or if a predetermined time has passed, the authentication unit 220 generates and transmits a new authentication number to the buyer terminal.

The guarantee management unit 230 generates the guarantee information of the product based on the information stored in the database unit 210 and the authentication unit 220. At this time, the warranty information includes information such as buyer information, seller information, product information, key value unique to the product, warranty period, and warranty repair history.

On the other hand, regarding the warranty period, the following three methods are available.

First, the warranty management unit 230 can generate the warranty information by processing the time at which the product key value is generated in the authentication unit 220 as the guarantee period start time.

Second, when the seller delivers the buyer information and the product information together with the guarantee management unit 230 through the seller terminal 300 at the time of purchase of the product, it is assured that the buyer information and the product information are received from the seller terminal 300 It is also possible to generate the guarantee information by processing at the period start time.

Third, the warranty management unit 230 generates the warranty information by processing the point at which the product-specific key value is generated and the point in time when the buyer information and the product information are received from the seller terminal 300, whichever is earlier, It is possible.

The warranty period may be a normal period depending on the type of product, but it may be unclear when the warranty period starts, so that the warranty period can be set clearly through this method to prevent disputes between buyer and seller .

When the time of receiving the buyer information and the product information from the seller terminal 300 is faster than the time when the key value unique to the product is generated in consideration of the normal delivery period at the time of sale, May be added to the system.

On the other hand, the seller terminal 300 can write the buyer information and the product information in the NFC tag at the time of selling the product and set the NFC tag as read-only. In this process, the seller terminal 300 transmits the product information and the buyer information to the authentication server 200 in advance, and the buyer terminal 100 transmits the same product information and buyer information to the authentication server 200 through the NF- The product registration can be performed more smoothly and easily, and the guarantee period can be prevented from being distorted.

The warranty manager server 410, 420, 430 receives the trouble repair information generated from the purchaser terminal 100 in connection with the authentication server 200, and generates the estimate information therefrom.

There may be only one assurance manager server 410, 420 or 430, but preferably two or more. The Warranty Manager Server is a server operated by the Warranty Manager that provides warranty service and repairs the defective product.

The warranty manager can be either a manufacturer's own warranty service provider or a third-party repair shop. Since it takes a lot of time and money to construct a warranty service infrastructure, start-ups of manufacturing companies and small and medium-sized enterprises are required to register private repair shops as official certified repair shops in order to prevent unnecessary resources from being consumed in constructing a guarantee service infrastructure Thus, there is a significant advantage in that the cost required to construct a warranty service network can be reduced.

On the other hand, the purchaser terminal 100 can inquire the quotation information through the authentication server 200 and select a guarantee manager to perform the repair. At this time, when the failure repair information is received from the purchaser terminal 100, the authentication server 200 analyzes the warranty information and determines whether the product is a product that can be guaranteedly repaired.

In addition to the estimation information, the assurance manager may transmit the assurance processing information, which indicates whether or not it is a failure corresponding to the assurance repair range, to the authentication server 200 so that the assurance repair can proceed smoothly.

Next, a technical description of product registration and product post management using the ENF warranty will be further described with reference to the flowcharts shown in FIGS. 2 and 3. FIG.

FIG. 2 is a detailed flowchart illustrating a process in which product warranty information according to an embodiment of the present invention is registered on-line.

The seller terminal 300 is tagged close to the NFC tag 1000 in the process of purchasing the product directly from the shop in the offline shop or selling the product such as immediately before the seller packs or ships the product in the online shop Accordingly, the product information is read from the NEFF tag (S100).

Then, the seller terminal 300 transmits the product information read through the NF communication method to the authentication server 200. [ At this time, the seller terminal 300 can further transmit the buyer information together with the product information. Also, as described above, at the time of selling the product, the buyer information and the product information are written to the NEFF tag, the NIFF tag is set to the read-only state, It may be provided to the purchaser.

The authentication server 200 stores the buyer information and the product information, and then proceeds to register the product when the product information is transmitted from the buyer terminal 100.

The seller then delivers the sold product to the buyer.

The buyer reads the product information from the NEFF tag as the tagging is performed in proximity to the NEFF tag 1000 through the buyer terminal 100 (S120).

At this time, if the assurance management application is not installed, the assurance management application is requested, and the installation is performed after the download (S130).

When tagging is performed when the warranty management application is installed, the purchaser terminal 100 automatically drives the installed assurance management application, generates product information according to a form provided by the assurance management application, and transmits the product information to the authentication server 200 (S140).

Thereafter, the authentication server 200 issues an authentication number for the product information and delivers it to the purchaser terminal. The authentication number can be transmitted through a push alarm system through an application, and can also be transmitted through an SMS / MMS system through a mobile communication network Do.

At this time, the authentication number may be an authentication number including one or more of numbers, letters and special characters recognized as valid only for a predetermined time.

When the authentication number is input to the purchaser terminal 100, the input authentication number is transmitted to the authentication server 200 (S150). At this time, if the authentication number delivered from the purchaser terminal 100 is not equal to the issued authentication number, or if the authentication server 200 has passed the predetermined time, the authentication server 200 generates and transmits a new authentication number to the buyer terminal.

When the authentication number is normally transmitted, the authentication server 200 generates the key value unique to the product by combining the product code and the authentication number included in the product information, and generates the warranty information by linking the product information and the key value unique to the product (S160). The warranty information includes the warranty period information of the product purchased by the purchaser and can be used to determine whether warranty repair is possible when the warranty service is performed.

3 is a detailed flowchart illustrating a process of providing a warranty service in connection with product warranty information according to an embodiment of the present invention.

If a failure occurs, the buyer terminal 300 transmits the failure repair information generated through the assurance management application to the authentication server 200 (S300).

The trouble repair information can be generated by photographing a part where a failure has occurred by a buyer and selectively inputting detailed failure details in the warranty management application. To this end, the warranty management application may provide a description of the scope and duration of warranty coverage for each specific part of the product so that the purchaser can easily view it. For example, if the product is a cloth, the warranty period is 12 months (free), sewing defect is 2 months (free), fabric defect is 1 month (free), and laundry accident is 2 months And the buyer generates failure information in such a manner as to select an item for which warranty repair is requested.

After that, the authentication server 200 browses the generated warranty information and transmits the details of assurance to the purchaser terminal 100 (S310, S320). At this time, upon viewing the warranty information, the authentication server 200 may analyze the warranty information and determine whether the failure repair information can be guaranteed or repaired from the purchaser terminal 100.

Thereafter, the authentication server 200 transmits failure repair information to at least one of the assurance manager servers 400 and requests quote information (S330). At this time, the authentication server 200 may transmit the guarantee information together to inform the assurance manager server 400 of the detailed range of assurance of the product.

Then, the assurance manager server 400 generates the estimate information and transmits it to the authentication server 200 (S340). At this time, the assurance manager server 400 may send the assurance information to the authentication server 200 together with the assurance information, which indicates whether or not it is a failure corresponding to the assurance coverage.

Then, the buyer terminal 100 inquires the estimate information through the authentication server 200, selects a guarantee manager to perform the repair, and requests the repair manager to repair the failure (S350, S360).

At this time, the purchaser terminal 100 may select the warranty manager after inquiring the details of the warranty manager, the telephone number, the conventional repair date, and the satisfaction level through the authentication server 200. [

After that, the buyer and the warranty manager send and receive the product through the delivery and execute the product repair.

Thereafter, the selected assurance manager completes the assurance process by processing the settlement of accounts, etc., regarding the product repair through the authentication server 300 (S370).

There has been a lot of dispute in the past when a buyer is notified of an opaque repair price after receiving a product for warranty repair or is notified that warranty repair is impossible. However, by introducing the above-described invention, since there is an authentication server between the buyer and the warranty manager, it is possible to easily receive the estimates of various assurance managers and to perform warranty repair through the assured guarantee manager, .

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments.
