Description

Electronic coupon trading device and electronic coupon trading method {ELECTRONIC COUPON DEALING SYSTEM AND ELECTRONIC COUPON DEALING METHOD}

The present invention relates to an electronic coupon trading apparatus and electronic coupon trading method for forming a smooth trading system of electronic coupons.

Electronic coupons include all types of coupons that can be identified, such as coupons for coffee shops, gifticons, as well as coupons printed on paper, and are defined as all types of coupons that can be distributed online via the Internet or wired or wireless networks. .

Electronic coupon transactions that issue electronic coupons and transfer them to others, such as presenting electronic coupons to others through electronic means such as e-mail , SMS, or MMS, are rapidly increasing with the spread of smartphones. The use of electronic coupons is continually expanding, and various products are becoming electronic coupons and are being traded through electronic media.

However, if the expiration date is fixed for the electronic coupon, there is a disadvantage in that the use of the electronic coupon is missed even if the electronic coupon cannot be used or the fee is paid within the expiration date due to the personal circumstances of the buyer. If the transfer is possible by a simple procedure within the validity period, this problem can be solved. However, due to the nature of the coupon operation system, the transfer of the online coupon is impossible after the electronic coupon is sold to a specific user. Despite the recent increase in the need for transactions of electronic coupons, such as the sale of electronic coupons or the presentation of gifts as gifts between users with electronic coupons, the electronic coupon management system has not responded. Accordingly, there is a need for a new development of a trading system that enables free trading of electronic coupons but can accurately determine and determine who the true coupon holder is.

In the case of paper coupons that are traded off-line, the authentication number or barcode is printed. However, if the illegal user who steals the paper coupon or steals the authentication coupon presents the coupon, it is difficult for the merchandise exchange to verify whether the user is illegal. You have no choice but to present the prize to. Such difficulty in preventing illegal copying or theft is also an obstacle to the trading system of electronic coupons.
Then, the electronic coupon is exposed to the risk of theft or double use, the moment the coupon number is exposed or output to a medium such as paper. Therefore, in the case of exposing the coupon number such as exposing the coupon number or printing the electronic coupon, a method for preventing illegal theft or double use of the same level as the procedure for transferring (or presenting) the electronic coupon to others is proposed. It is necessary to prepare.

In addition, recently, social commerce that sells electronic coupons on a web site has appeared, but it is not supported by the system for users to freely trade electronic coupons by doctors.

The present invention is to improve the above-mentioned problems, an electronic coupon trading device that supports the function to block the illegal copying of electronic coupons or illegal distribution of coupons as well as paper coupons, and to freely trade electronic coupons between users; It is to provide an electronic coupon trading method.

In one embodiment, according to the electronic coupon transaction apparatus of the present invention, the user terminal unit provided on the user side for querying the electronic coupon held by the user or input and output the coupon information during the transaction of the electronic coupon; An authentication terminal unit generating an authentication request of the electronic coupon; Coupon server provided with a database unit for storing the coupon information and an authentication unit for processing the authentication request; It includes, and when the output of the coupon information by updating the coupon information, the dual transfer or illegal use of the electronic coupon is blocked.

In one embodiment, according to the electronic coupon trading apparatus of the present invention, a coupon code corresponding to a unique identification number for distinguishing each electronic coupon, the electronic coupon is in a valid state capable of exchanging goods or an invalid state in which commodity exchange is impossible Coupon information is stored in the coupon server including a status code corresponding to an identifier for distinguishing whether or not, an attribute value including information on a product exchanged for the electronic coupon, or information on an expiration date of the electronic coupon, A new coupon code is generated in synchronization with an output point of time (including a screen output and a paper output. The same as below) to which the coupon information is exposed to the outside of the coupon server for a transaction of the coupon , wherein the newly generated coupon code The attribute value of is kept the same as the attribute value of the existing coupon code, and the status code of the existing coupon code is invalidated. Updated to the state.

In one embodiment, according to the electronic coupon trading apparatus of the present invention, the coupon code of the electronic coupon immediately after the transfer or output of the electronic coupon is changed to a new coupon code, the attribute of the electronic coupon before or after the transfer or output of the electronic coupon The value remains the same. Therefore, the transferred or printed electronic coupon is different from the coupon code before the transfer or output , and thus is distinguished from each other, and the electronic coupon before the transfer or output (ie, the transfer coupon of the transferor) has no effect on commodity exchange. The coupon code , which is converted into a code and generated by assignment or output (ie, the assignee's electronic coupon), obtains a status code that is in effect for commodity exchange.

In one embodiment, according to the electronic coupon trading apparatus of the present invention, coupon information of an electronic coupon newly generated according to a new purchase of a first user is stored in each data field in a first table of a coupon server, and the first user that if the output of the electronic coupon or transferred to a third party, the first table of the existing electronic coupons that existed in the account of the first user is changed to the second table can not be a commodity exchange, it is the first user that electronic As soon as a coupon is output or a third party takes over, coupon information of a third table in which an electronic coupon having a new coupon coat can be exchanged is generated and stored in the coupon server.

In one embodiment, according to the electronic coupon trading device of the present invention, all the information generated during the transaction of the electronic coupon is stored in the coupon server, the coupon code corresponding to the unique identification number for distinguishing each electronic coupon and the electronic coupon The setting and change of coupon information, including a status code for identifying whether a product exchange is in a valid state, are all made in the coupon server, thereby preventing double transfer or illegal transactions of the electronic coupon.

In one embodiment, according to the electronic coupon transaction method of the present invention, when the first user transfers the electronic coupon to a third party through a text message (SMS) or multimedia message (MMS) of the mobile phone, the first user retains status code of the electronic coupon is changed is changed to 'Forward' to non this item exchange state, as the third party is if you acquired the electronic coupon generating an electronic coupon has a new coupon code status code who are active as 'Live' It becomes the state that product exchange is possible . This process is called 'coupon information change step'. After the coupon information changing step, if the electronic coupon pumped by the third party is presented to the commodity exchange destination, the authentication request of the coupon information is transmitted to the coupon server, and if the authentication of the coupon server is valid, the commodity exchange is completed. The status code of an electronic coupon used by a third party is changed to 'USED'.

According to the present invention, the electronic coupon issued to a specific person is stored in a user account of the database unit, and can be freely used at a desired place and time by various output methods when the user needs it, and the coupon information is output to the outside of the coupon server. According to the present invention in which the coupon code or status code is changed at the moment, illegal use is prevented.
In addition, even if a number of output actions occur, the status code of the electronic coupon before printing is changed to 'Forward', and the status code of the electronic coupon with the new coupon code generated by the printing behavior is changed to 'Live'. For example, a new electronic coupon with a 'Live' status code can be distinguished from an electronic coupon before its output in the 'Forward' status, and the unity of the electronic coupon can be maintained accurately. This greatly contributes to the activation of e-commerce.

1 is a block diagram of an electronic coupon transaction apparatus of the present invention.
2 is a flowchart illustrating the operation of the electronic coupon transaction apparatus of the present invention.
3 through 6 illustrate various embodiments of an electronic coupon transaction.

Referring to FIG. 1, the electronic coupon transaction apparatus of the present invention includes a user terminal 20, an authentication terminal 30, and a coupon server 10.

The user terminal unit 20 is provided on the user side and has an input / output unit 21 for querying electronic coupons stored in their accounts or inputting / outputting coupon information when trading electronic coupons, and a display unit 22 for displaying transaction information. do. Coupon information and user information are input and output through the input / output unit 21, and the display unit 22 displays this information on the screen. The user terminal unit 20 includes a portable telephone, a smartphone, a PC, a notebook computer, and a multimedia device.

The authentication terminal unit 30 is for authentication of the electronic coupon when the electronic coupon is presented at the commodity exchange, and requests the authentication of the electronic coupon to the coupon server 10.

The coupon server 10 may include an authentication unit 12, a database unit 11, and an authentication unit corresponding to an authentication request of a database unit 11, a user terminal unit 20, or an authentication terminal unit 30 in which coupon information is stored. And a control unit 13 for controlling the operation (processing for the authentication request ) of 12 and processing the electronic coupon transaction process.

2 is a flowchart illustrating the operation of the electronic coupon transaction apparatus of the present invention. 3 to 6 illustrate how coupon information is handled in an electronic coupon transaction. 1 to 6, the operation of the electronic coupon transaction apparatus and the electronic coupon transaction method using the same will be described.

The "electronic coupon" of the invention, as described earlier, as including a paper-ku phones sold in the coupon in a virtual reality space sold online through the user terminal unit 20, of course, off-line,

The coupon information of the electronic coupon according to the present invention includes a coupon code, an attribute value of the electronic coupon, a status code of the electronic coupon, owner information of the electronic coupon, and information on an output item of the electronic coupon.

The coupon code corresponds to a unique identification number for distinguishing each electronic coupon, and refers to a barcode or an encrypted number / character. In the illustrated example, an electronic coupon with a coupon code of '1234' and an electronic coupon with a coupon code of '4321' are distinguished and distinguished from each other.

The attribute value of the electronic coupon includes information about a product exchanged for the electronic coupon, an expiration date of the electronic coupon, an exchange destination for using the electronic coupon, and the like. In the example shown, the attribute value remains the same as 'QWER' at the time of initial issue despite the repeated transaction of the electronic coupon. This means that even if an electronic coupon is traded and transferred to another person, the product information or expiration date contained in the electronic coupon is kept the same as when it is first issued.

The status code of the electronic coupon is an identifier for distinguishing between a valid state capable of exchanging goods or an invalid state impossible of exchanging goods.

In the example shown, if an electronic coupon is commodity exchangeable and can be transferred to another person in the future and can be printed or printed in the future, the status code of the electronic coupon becomes 'Live'. On the other hand, if it is transferred to another person or printed, the attribute code of the electronic coupon becomes 'Forward', and when the product exchange is completed and presented to the commodity exchange destination, the status code is classified as 'Used'.

Owner information of the electronic coupon is information that can identify the owner, such as the ID, telephone number, e-mail address of the owner account, it is managed for each coupon code of the electronic coupon .

The output of the electronic coupon is output when the electronic coupon existing in the virtual space, such as the database unit 11, is displayed on paper or a screen, or transferred to the user terminal unit 20 of another person through SMS / MMS / email. Contains information. The output item of the electronic coupon contains information such as an output method, an output content, and a PIN.

In the example shown, the output method, when SMS / transfer of electronic coupons via MMS, transfer of e-coupons via e-mail, via the Internet, forward the e-coupon to another user account, print the electronic voucher (printed on paper at any time In a transferable state), and the like. The output details are details of the output method, including the transferee's phone number for transactions via SMS / MMS, the transferee's email address for transactions via email, and the transferee's user account ID for delivery to other user accounts.

PIN (personal identification number) is the personal identification number of the assignee. The PIN serves as a password for confirming whether or not the assignee is not leaked to others when the coupon information is displayed or downloaded on his user terminal 20.

The electronic coupon operating apparatus and method of operation of the present invention are briefly described as follows. Electronic coupons are freely traded through the Internet and wired and wireless communication networks in a virtual space like the user terminal unit 20.

In the present invention, the meaning of 'output' includes a case in which coupon information is exposed to the outside of the coupon server 10, and the electronic coupon transaction involves an 'output' action. The coupon code is updated with a new coupon code by synchronizing at the 'output' point when the coupon information is exposed to the outside of the coupon server 10 for the transaction of the electronic coupon, and the status code is invalidated (for example, 'Forward' state). While updated, the attribute value remains the same. Accordingly, fraudulent use of electronic coupon transactions is prevented.

In one embodiment, the attribute value of the electronic coupon including the product information is maintained before and after the transfer, but if the electronic coupon existing in the database unit 11 of the virtual space or the coupon server 10 is output on the screen or paper The electronic coupon is placed in a transferable state at any time, so as soon as the electronic coupon is output on the screen or paper, the status code of the electronic coupon is updated to a state in which there is no commodity exchange effect (e.g., 'Forward' status). A new coupon code with a status code that is effective for commodity exchange is generated , thereby identifying valid and invalid electronic coupons.

That is, two coupons having the same attribute value but different coupon codes are distinguished from each other because the electronic coupon changes immediately upon transfer or output. For an identifiable electronic coupon, the assignee's electronic coupon is changed to a status code that is not in effect and the assignee's electronic coupon obtains a status code that is in effect.

More specifically, it is as follows. When the first user purchases a new electronic coupon, coupon information is generated in the coupon server 10. The first table 110 represents coupon information of an electronic coupon newly generated according to a new purchase of the first user for each data field.

Referring to the first table 110, for example, the coupon code is '1234', the attribute value is the first issued 'QWER', and the previous code is '0000' because no transaction activity of the electronic coupon at all '0000' ', The status code is' Live' indicating a state in which goods can be exchanged at any time, and the owner ID of the electronic coupon corresponding to the first table 110 is' A '.

The coupon code contained in the first table 110 may be displayed on the electronic coupon, the user terminal 20, and the authentication terminal 30 in the form of a barcode, a number or a letter, or an encrypted number or letter.

When the first user transfers or outputs the electronic coupon to a third party, the first table 110 of the existing electronic coupon existing in the first user's account is not exchangeable and cannot be transferred or printed to the third party. The second table 120 cannot be changed. The electronic coupon output by the first user or the electronic coupon pumped by the third user has coupon information displayed by the third table 130 capable of exchanging goods.

Examples of "transfer" include text messaging (SMS), multimedia messages (MMS), e-mail transmission of mobile phones, online transmission to third parties with other accounts, and printing on paper. If you print an electronic coupon on paper, the printed electronic coupon can be transferred to a third party at any time and merchandise can be exchanged, even if the first user owns the printed electronic coupon. Seen as 'transfer'.

Referring to FIG. 3, an electronic coupon is transferred to a third party through a text message (SMS) or a multimedia message (MMS) of the mobile phone. The coupon code, the attribute value, the previous code, and the owner information of the second table 120 are not changed, and the status code is changed to 'Forward', thereby making it impossible to exchange products. In the output, the transfer information is stored, 'SMS / MMS' is stored in the method field, and the telephone number '010-1234-5678' which received the SMS / MMS is stored in the content field.

Looking at the third table 130 containing the coupon information of the electronic coupon transferred by the third party, only the attribute value of the third table 130 is intact, and all remaining information is regenerated. The attribute value contains the product information including the expiration date, brand name, and exchange destination of the electronic coupon, so the same value is maintained even if the owner of the electronic coupon changes. On the other hand, a coupon code to identify that the owner has changed the electronic coupon, for example, is changed to "4321", the previous code field is the coupon code of '1234' of the first table 110 stores, in the electronic coupon The transfer history can be tracked, and the status code is stored 'Live' indicating that the commodity can be exchanged, and the phone number received by the SMS / MMS is stored in the owner's phone number for use in identifying a new user . If the history of the coupon code is managed, it is known from which electronic coupon is transferred, thereby preventing double use or illegal use of the electronic coupon.

The first table 110, the second table 120, and the third table 130, which are a series of information about the transaction of the electronic coupon, are all stored in the coupon server 10. All information generated during the transaction of the electronic coupon is to go through the coupon server 10, and the setting / change of coupon information, including the coupon code or status code is all made in the coupon server 10, the double transfer or illegal transactions are blocked.

When the electronic coupon acquired by the third party is presented to the commodity exchange destination, the authentication request for the coupon information is transmitted to the coupon server 10 through the authentication terminal unit 30. If the authentication confirmation step of determining whether the authentication of the coupon server 10 is valid is normally processed, the third party who presented the commodity exchange destination and the electronic coupon can make a safe commodity transaction. When the authentication request or product exchange is completed, the status code of the third table 130 of the coupon server 10 is changed to 'USED', and the use of the electronic coupon is completed.

The coupon code is input to the authentication terminal unit 30, and the authentication terminal unit 30 transmits an authentication request to the authentication unit 12 of the coupon server 10. When the product is exchanged according to the authentication result of the authentication unit 12, the product sale information is transmitted to the database unit 11 of the coupon server 10.

When the electronic coupon is output, the first table 110 of the electronic coupon is immediately changed to the second table 120, and the third table 130 having the same attribute value is the database unit of the coupon server 10. 11 is stored. When the output electronic coupon is used for commodity exchange, the status code of the third table 130 becomes 'Used'. The e-coupon no longer has a table with a status code of 'Live' and the e-coupon transaction history is stored, thereby preventing the risk of illegal use of the e-coupon or double trading of a commodity customer.

Referring to FIG. 4, an electronic coupon is transferred to a third party through an email. The coupon code, the attribute value, the previous code, and the owner information of the first table 110 are not changed, and only the status code is updated to 'Forward' to be changed to the second table 120 , and the product exchange is impossible. In the output of the second table 120, as information about the transfer, 'E-mail' is stored in the method field, and an address 'abc@ddd.com' which has received an email is stored in the content field.

When the assignor transfers the electronic coupon to a third party (transferee), he or she may optionally set and save a PIN. When the PIN number is set, the assignee receives the e-mail with the coupon code recorded or displayed and inputs the PIN number. That is, when the assignee tries to inquire or download the coupon information from his user terminal, the coupon server 10 of the present invention requests the input of the PIN number and passes the PIN authentication when the contents match and the coupon information is passed. Allows inquiry or download.

Looking at the coupon information of the assignee, the attribute value of the third table 130 remains the same, and all remaining information is regenerated. The coupon code is set to '4321', the previous code is stored '1234', the status code is 'Live' indicating that the product can be exchanged, the e-mail address is stored in the owner information is used to identify the new owner.

The coupon server 10 retrieves the user information having the email address 'abc@ddd.com' among the user accounts, and retrieves the ID, telephone number, and email address of the same user account, and then the data field of the third table 130 as well. The user account information of the database unit 11 of the coupon server 10 may be matched in real time or periodically. Therefore, since accurate information management of the electronic coupon owner is made, double transfer or illegal transactions of the electronic coupon are blocked.

5 illustrates a case of transferring an electronic coupon to another user's account on the Internet. Coupon information of an electronic coupon transferred to a third party (assignee) is stored in the database unit 11 in the form of a third table 130, and the third party's ID is 'B' in the owner information of the third table 130. 'Is stored. The rest of the description is omitted to avoid duplication.

FIG. 6 illustrates a case where the first user 'A' outputs the electronic coupon stored in his account on paper for his use . At this time, since the electronic coupon stored in the user account and the printed electronic coupon can be distinguished from each other to avoid duplicate use, the coupon code is changed at the time of outputting, and thus the status code is also distinguished. Attribute values are the same. At this time, in the case of the outputted electronic coupon, the owner information of the third table 130 is not changed, but is maintained the same as the owner information before the output.

In summary, when the electronic coupon is output, printed or transferred, a new coupon code different from the original coupon code stored in the coupon server 10 is generated, and the attribute value maintains the same value. The existing coupon code is invalidated, and the status code of the newly generated coupon code is validated as 'Live'.

The transferee's new electronic coupon stores and manages the previous coupon code values so that it can be tracked from which electronic coupon was regenerated afterwards.

Another reason for changing the coupon code is that once the coupon code is exposed, if the coupon code or the coupon image is illegally copied and presented to the commodity exchange, there is a risk of double transaction. Thus, once exposed coupon code is invalidated and new coupon code is regenerated to prevent the possibility of fraudulent use.

The electronic coupon issued to the third user as well as the third user is stored in the user's account of the database unit 11 and is freely output in various output methods when the user needs it.

If the user 'A' transfers an electronic coupon with the same attribute value to the assignee 'B' through the 'B' account, delivers it to the 'B' via SMS / MMS, sends it to the 'B' by email, etc. Multiple transfers or outputs may occur as an output method.

However, if the first of a number of transfer and transfer actions by owner 'A' is executed, the status code of the coupon of the first owner 'A' is changed to 'Forward' and the owner of the third table is 'B'"because changes, the owners' changed after the first owners' B a 'can not be further transferred or printed out acts acts. The assignee 'B' has an electronic coupon with a 'Live' status code, so there is no problem in maintaining the unity of the electronic coupon. Therefore, fraudulent use due to plural outputs and double transfer is prevented.

3 to 6, despite the transfer of the electronic coupon, the attribute value and the coupon code are the same, and the field of the output item and the field of the owner information are updated. If the user 'B' presents the electronic coupon in any output form selected by the merchandise exchange, the electronic coupon can be exchanged, and the electronic coupon of the coupon code '4321' is changed to the 'USED' status code.

Although not shown, when the same user 'A' outputs the electronic coupon to the user several times using various output methods such as a mobile phone, a PC, paper, etc., the second table 120 changed to 'Forward' similarly to FIG. 6. Since the output is continuously updated and the owner information of the third table 130 generated as 'Live' is continuously updated with 'A' , the 'Live' coupon is single, so double transfer or fraud is not a problem.

That is, when the user 'A' outputs the electronic coupon to the user several times using various output methods, the output is continuously updated in the second table 120 changed to 'Forward' similarly to FIG. In each output, a third table 130 having a 'Live' status code and a new coupon code is continuously generated, and its owner information is kept at 'A', so the 'Live' coupon is single, so double transfer or fraudulent use This is not a problem.

If the owner 'A' attempts to deliver the electronic coupon to the assignee 'B' multiple times , the coupon of 'A' is changed to 'Forward' status by the initial transfer, and 'A' is no longer the electronic coupon. There will be no printing or transfer of coupons, so double transfer or fraud will not be a problem.

And consider the case where the owner 'A' repeats the transfer to several third parties ('C', 'D'), as soon as 'A' outputs for 'C' , the second table of 'A' Since 120 is changed to 'Forward', 'A' cannot double transfer the electronic coupon owned by him to 'D', and thus illegal use is blocked. The same is true when a third party makes multiple assignments to another person.

However, if the user 'A' transfers to the assignee 'B' and the 'B' transfers to the new transferor 'C', the repeated transfer or output actions such as the continuation of the coupon code are changed every time. Since the generation of a new coupon code is repeated, normal distribution of coupons is freely guaranteed.

Therefore, in the electronic coupon according to the present invention, the coupon code and status code and the owner information of the electronic coupon is updated at the moment the coupon information is output to the outside of the coupon server 10, thereby preventing the illegal use of the electronic coupon. . In addition, even if multiple output actions occur, the status code is changed to 'Forward' and 'Live' before and after each output action, so that an electronic coupon having a 'Live' status code is distinguished from an electronic coupon in a 'Forward' state. And the unity of the electronic coupon is maintained accurately.

The identity of the assignor or assignee is immediately identified through the data field of the coupon information, thereby preventing double issuance of the electronic coupon.

The use of electronic coupons is continuously expanding, and various offline products can be distributed in the form of online or mobile coupons through electronic coupons. The attribute value of the electronic coupon includes information such as product type, product brand, exchange destination, and expiration date.When the electronic coupon is presented to the product exchange, exchange information such as exchange date and product exchange is generated. It is stored on the server. After the owner exchanges the electronic coupon with the product, and the evaluation information on the product or the merchandise exchange destination along with the coupon information in the coupon server and presents a device and method for inquiring this.

For example, in a general online shopping mall, a purchase review left by a first purchaser is used as important information for determining the popularity of a product, which has an important influence on a purchase decision of a new buyer. Since electronic coupons are exchanged for physical goods or provided with services at the point of exchange, not at the point of sale, when the user stores consumer evaluations of the actual goods or services provided through the electronic coupon with the coupon information, It can contribute to improving purchasing satisfaction.

When the user presents the electronic coupon and exchanges it with a real product or service, the coupon information and the exchange information are recorded together in the coupon server. When the coupon server recognizes that the coupon has been used, the coupon request is made to the electronic coupon user. The coupon server receives the user's reviews from the coupon user in various ways. The testimonials may be in the form of text expressing the consumer's intentions, a previously-satisfied satisfaction index, and a satisfaction / dissatisfaction measure.

The coupon server requests the input of testimonials for the exchange through the account of the coupon user, the text of the coupon user, the email of the coupon user, and the user who receives the request of the testimonial writes the testimonials back to the coupon server. do.

The coupon user may access the coupon server, enter coupon information used by the user, or select coupon information used by the user according to a search method provided by the coupon server, and then input a review of the corresponding coupon. The coupon user may input a user's review of the coupon information used by the user using a program embedded in the user terminal unit. The program embedded in the user terminal unit communicates with the coupon server to confirm completion of the coupon use, the coupon server requests the user to input review information on the corresponding coupon, and the user terminal unit transmits the user-entered review to the coupon server. To send. The coupon server stores coupon information, product exchange information, and user reviews together in the database unit.

Although embodiments according to the present invention have been described above, these are merely exemplary, and it will be understood by those skilled in the art that various modifications and equivalent embodiments of the present invention are possible therefrom.
