The present invention relates to a cache-back system and a cache-back method using the same, which cache-backs a certain percentage of the seller's profits to the purchaser in real time.

With the rapid economic growth and changing consciousness, consumer's needs are diversifying year after year. According to the consumer's disposition, the retailers are also showing a variety of products.

However, it is true that the sales of small stores are rapidly decreasing due to the appearance of large discount stores such as large discount marts, home shopping, and internet shopping malls. In addition, the company is striving to secure fixed customers among large discount stores amid intense competition among vendors.

As a part of this, a certain point is given according to the purchase, if you earn more than a certain point, aka points earning card that pays a product or discount according to the accumulated points will be a typical example. In the case of such a credit card is widely used from small small stores to large discount stores.

However, membership is essential to obtain certain points defined by the store. In addition, since a certain number of purchases or a certain amount of purchases must be made, it is difficult to collect points for most non-fixed customers. The reality is that most of them give up before their customers fill up their points.

In addition, as point-of-sale stores that use loyalty cards are becoming more common and customers' needs diversify, it is difficult to maintain fixed customers, unlike the early days when floating customers were established as fixed customers of the stores to collect points.

This difficulty is equally true in the way of selling products online or in person by offline visits.

Referring to the above points, the general point earning card is no longer a differentiated sales strategy of the store, a more direct and efficient strategy is urgently required.

In order to satisfy the above-described needs, the present invention provides a cache-back system and a cache-back method using the cache-back for a purchased product sold online and offline.

The present invention also provides a cache-back system and a cache-back method using the same, which calculates a discounted amount of a product purchased through an event at a point in time when a certain quantity of products are sold through online and offline, and reflects the same in a payment amount. do.

In order to achieve the above, the present invention, in a cache-back system that provides a cash-back service for goods sold online or offline, issues a lottery ticket for the goods sold online or offline, and the lottery ticket Store and manage information on the database, and if a predetermined number of lottery tickets are issued, apply for the lottery tickets at the request of the customers who possess the lottery tickets, perform the lottery for the lottery tickets for which the application has been made, The present invention proposes a cash-back service method for determining a refund amount by distributing a certain percentage of the total sales amount by the number of ranks given through the drawing.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

In the embodiments of the present invention to be described later to prepare an offline door-to-door sales and Internet shopping mall site, and database the cache-back point amount according to the number and ranking of the n-tree method according to the information and profit information of each product and the specified number of people Save it. When customer A views a product on an offline sales and shopping mall site and requests a purchase of a specific product therein, the company uses a cash-back lottery system to calculate a certain amount of profit generated by the product purchased by a specific customer other than customer A. It is a system that determines the rank and returns the amount corresponding to the rank to customers in cash.

First, with reference to Figures 1 and 2 will be described the overall concept of the online shopping mall and offline sales of the present invention. 1 is a view conceptually showing a flow of data processing and a state of transmission when a purchaser is connected through an internet network and a service request of a customer occurs.

A customer who wishes to use the cash-back lottery system of the present invention must be a member of an online shopping mall or an operator of offline visiting sales. Members who have become offline operators will maintain the authority of the operators without additional approval in the online shopping mall, and may be recognized as members. In the member registration process, an ID and a password are set, and an ID registered as an offline business operator is registered as an online shopping mall subdomain, thereby establishing a personal shopping mall of the business operator.

2 is a diagram showing an example of applying an embodiment of the present invention when a customer orders a product online. In FIG. 2, the member terminal 200 refers to a terminal used by a member subscribed to an online shopping mall, and the main server 250 refers to a server operating a cache-back service proposed by the present invention together with an online shopping mall. . Signaling indicated by a solid line in FIG. 2 is a procedure performed online, and a signaling performed offline by a dotted line.

Referring to FIG. 2, the member terminal 200 accesses and logs in to the main server 250, and receives product information from the main server 250. The product is searched based on the product information, and if there is a product to be purchased, the product is ordered to be purchased in step 210. In addition, the purchase price for the ordered product is settled by a procedure required in a normal online shopping. The online settlement may use a passbook payment, a credit card, a mobile phone settlement, a remaining point, and the like.

When payment for the ordered product is completed, the main server 2560 sends a lottery ticket to the member terminal 200 in step 212. In addition, the main server 250 maps the sent lottery ticket to a specific code and manages it.

The operator who operates the shopping mall through the main server 250 sends the goods made by the member through offline (step 214). When the member receives the ordered goods, the member confirms that the goods have been received using the terminal 200 (216). When the receipt of goods from the member terminal 200 is confirmed, the main server 250 pays the sales and management allowance to the shopping mall operator in step 218 when payment of the sales and management allowance is required.

However, if the member cancels the product purchase, the main server 250 invalidates the lottery ticket issued for the member. That is, the code for the lottery ticket is deleted from the database. The space where the code is deleted is reassigned for another member.

The main server 250 presets a threshold quantity for each product, and when the sale of the preset quantity of goods is completed, the issuance of the lottery ticket is terminated in step 220. Closing the drawing of the lottery is to close the issuance of the lottery for the event to be performed this time, so that the lottery for the next event can be issued continuously. However, if the product is out of stock, no more lotteries will be issued.

Although the main server 250 is not shown in FIG. 2, when the issuance of the lottery ticket for the event is closed, the main server 250 notifies the members who are eligible to apply for the event. The notification is made through an online medium (email, etc.), a communication medium (SMS, etc.), or the like.

Members notified that the issuance of the lottery ticket for the event is closed apply to the event using the terminal 200. The event entry may be in the form of transferring the previously issued lottery ticket to the main server 250.

The main server 250 notifies in advance of a period during which an event can be entered, and does not accept any further event entry when the known period ends. When the known period ends, the main server 250 performs a cache-back service for members who entered the event at the end of the known period. A detailed description of the cache-back service proposed by the present invention will be described later.

When the main server 250 determines the amount to be refunded for the goods purchased for each member through the cache-back service, the main server 250 configures the cache-back information and transmits the cash-back information to the member terminal 200 (step 224). The cache-back information includes ranking information by lottery and refund amount information corresponding to the ranking. The cache-back information may be performed through a communication medium (SMS, etc.) as well as an online medium (email, etc.).

In step 226, the member confirming the cache-back information requests payment of the refund amount using the terminal 200. The main server 250 pays the refund amount when the payment request from the member terminal 200 is received. The information needed to pay the refund amount must be registered in advance. The information may be a member's bank account number. And the refund amount may be paid in points that can be used for gift certificates or shopping, not cash.

3 is a diagram illustrating an example in which an embodiment of the present invention is applied when a customer orders a product through offline. In FIG. 3, the operator terminal 302 refers to a terminal used by an offline operator, and the main server 304 refers to a server operating a cache-back service proposed by the present invention together with an online shopping mall. The signaling indicated by the solid line in FIG. 3 is an online procedure, and the signaling capability indicated by a dotted line is performed offline.

Referring to FIG. 3, the operator 302 visits the customer 300 directly and promotes the products to be sold (step 310). Unlike the on-line sales method, such door-to-door sales can recognize the value of customers and provide services that can satisfy customers. In addition, by actually showing and describing in detail the products that customers want or need, it is easier for customers to purchase products.

The customer 300 purchases a desired product and pays a purchase amount thereof (step 312). The payment can be made without payment, credit card, mobile phone payment. The operator 302 issues a lottery ticket to the customer (step 314).

When the operator sells the product, the operator registers the sales information and the lottery ticket issued to the customer in the main server 304 by using the operator terminal 302 (step 316). The main server 304 encodes the sales information and the lottery ticket registered from the operator 302 and manages them through a database. The operator who manages the main server 304 and operates the shopping mall pays the sales and management allowance to the operator 302 in step 318.

The operator who manages the main server 304 and operates the shopping mall sends the goods for which the order is made through offline (step 320). When the customer receives the ordered goods, the customer is notified that the goods have been received, thereby confirming that the goods are delivered correctly (step 322). Payment of the sales and management allowances made in step 318 may be made after the receipt of the goods is confirmed. This is because a situation in which a product purchase is canceled by a customer may occur. If the product purchase is canceled, the main server 304 invalidates the lottery ticket issued to the customer. That is, the code for the lottery ticket is deleted from the database. The space where the code is deleted is reallocated for other customers.

The main server 304 presets a threshold quantity for each product, and when the sale of the predetermined quantity of products is completed, the lottery registration of the corresponding product is completed in step 324. Closing the lottery ticket registration is to end the lottery ticket registration for the event to be performed this time so that the lottery ticket for the next event can be continuously registered. However, if the product is not in stock, no further lottery tickets will be issued.

Although the main server 304 is not shown in FIG. 3, when the registration of the lottery ticket for the event is closed, the main server 304 notifies the customers who are eligible to enter the event. The notification is made through an online medium (email, etc.), a communication medium (SMS, etc.), or the like.

Customers notified that the lottery issuance for the event has closed have entered the event. The event entry can be made through various routes.

The main server 304 notifies in advance of a period during which an event can be entered, and does not accept any further event entry when the known period ends. When the known period ends, the main server 304 performs a cache-back service for the customers who entered the event at the end of the known period. A detailed description of the cache-back service proposed by the present invention will be described later.

When the main server 304 determines the amount to be refunded for the goods purchased for each customer through the cache-back service, the main server 304 configures the cache-back information and provides the same to the customer 300 (step 328). The cache-back information includes ranking information by lottery and refund amount information corresponding to the ranking. The cache-back information may be performed through a communication medium (SMS, etc.) as well as an online medium (email, etc.).

In step 330, the customer 300 confirming the cache-back information requests payment of the refund amount. When the payment request from the customer 300 is received, the main server 304 pays the refund amount (step 332). The information needed to pay the refund amount must be registered in advance. The information may be a member's bank account number. And the refund amount may be paid in points that can be used for gift certificates or shopping, not cash.

4 is a diagram illustrating an operation flow of a main server according to an exemplary embodiment of the present invention.

Referring to FIG. 4, the main server performs a log-in procedure at the request of a member in step 410. When the log-in is made, the product information is transmitted to the member terminal in step 412. In step 414, the main server monitors whether there is a request for a specific product from the member. In addition, when an order request for a specific product is made from the member, the product order is accepted.

Thereafter, in step 416, the payment for the goods ordered is made from the member. If the payment is made, the main server proceeds to step 418 and pays the sales and management allowance. At the same time, the main server issues the lottery ticket to the member and manages the coded information on the lottery ticket through the database corresponding to the member information.

If a predetermined quantity of goods are sold for the event by the above-described operation, the main server performs a cache-back service in step 420. The rank is determined for each member through the cache-back service, and a refund amount corresponding to the determined rank is calculated. The ranking information and the refund amount calculated will be notified for each member.

Thereafter, when a payment request for the refund amount is received for each member, the main server pays the refund amount requested in step 422.

Meanwhile, in FIG. 4, the processing flow for the on-line customer is shown, but only steps 410 and 412 are omitted for the off-line customer, and the remaining operations are processed by the same procedure.

5 is a diagram illustrating an operation flow of a cache-back service performed when a product order is made online.

Referring to FIG. 5, in step 100, a user accesses a server of the shopping mall by inputting a URL address to purchase a product of the online shopping mall 200. The user who enters the shopping mall performs a login authentication procedure in step 204. At this time, the login screen displayed on the user's terminal is as shown in FIG. 9A. If the ID and password input by the user on the screen of FIG. 9A match, the method authentication management such as a cookie managing the user terminal with authentication or a session managing the user data information with the server Is processed. Membership authentication protects against hacking and other risks that may occur during data transmission by 64Bit encryption of code for hacking and security.

A user authenticated as a member may display a product list 216 of a shopping mall in a browser and search for a desired product. For the first subscriber, the membership registration form 202 is provided and the membership registration process is performed. The data generated by the registration is registered in the database 10 of the present server. At this time, the personal information such as account, member ID, password, etc. to receive profits generated by the lottery system is designated.

After completing the membership registration or the existing member subscriber to confirm the ID and password (204). At this time, if you forget the member's ID and password, you can request their information (208), the requested information is a member by the data search step 210 to search the member DB and if the information entered is correct member Your ID and password will be sent to the registered E-mail. If you are not a member, the screen for joining is displayed.

The registered member searches for a desired product type in step 216. In this case, a plurality of products that are suitable for the user is moved to the detail information page 218, and the member selects the desired product from the output screen (220). When the product is selected, the inventory of the product is checked (224), and if there is a remaining quantity, the member writes an order form (226).

The order form screen is as shown in Figure 9c, the point of the lottery product purchases points are paid in a lottery ticket, and after the transaction can be returned to the cash-back by the point lottery method. Cash-back received here can be transferred to cash. This will be described again below.

When creating an order, specify the necessary information (color, size, quantity, etc.) in addition to the information recorded at the time of membership registration. The product information screen 218 is represented by a picture or a picture for identifying the appearance of the product, and is accompanied by a detailed description of the product such as characteristics, size, color, etc. of the product.

The product information screen 218 is as shown in FIG. 9B. Here, the difference from the general shopping mall is that you can check the maximum and minimum points that you have when you purchase a product by using the point lottery system instead of purchasing a general product. Return it.

When the order form 226 is completed, the order number is automatically generated 250, and requests the lottery ticket to the system server 252. The server retrieves the code number from the database (254) and issues (256) the retrieved code number as a lottery ticket. When the lottery ticket is issued, if there is no stock by checking the stock availability (246) of the product, the display of the out of stock 248 step, the product information screen 218 to display out of stock no more orders to be no more .

Hereinafter, a process of processing an online allowance by the lottery system based on the recorded information will be described.

At the stage where the lottery ticket is issued, the server determines whether a shopping mall distributor is present (230). The shopping mall distributor refers to an operator who receives a shopping mall in which a product purchase is made when a customer enters a shopping mall and purchases a product. If there is a shopping mall distributor by determining whether there is a shopping mall distributor, the data search 236 of the product DB 20 and the sales allowance DB 30 is performed by identifying the shopping mall distributor through the ID search step 232. In the data retrieval process, the sale allowance that the shopping mall seller can take is searched and the sale allowance is paid (234).

When the payment of the sale allowance of the shopping mall sale is completed, it is determined whether there is a recommender (238), and if there is a recommender, through the ID search step 240 to identify the recommender through the product DB 20 and the management allowance DB 40. The data search 244 is made.

The management allowance can be retrieved by the recommender in the data retrieval process and paid to the recommender (242). The seller and the recommender must be a business operator, where the business operator refers to a person who is to sell the online shopping mall offline.

In the process of registering one product, there is a process of sales allowance DB 30, management allowance DB 40, step setting DB (50), point setting DB (60). All of this configuration is an administrator's privilege. When the manager decides the product stage and the point, the manager automatically forms a stage such as the shopping system shown in FIG. 7 and stores it in the database.

On the other hand, the issued lottery ticket does not enter the lottery even if the transaction status is completed as shown in FIG. 9D. When the number of the designated number of stages set in the product registration process, the shopping mall displays the deadline 260, and notifies the person who is issued the lottery ticket of the same product collectively so that there is no disadvantage in the lottery entry. The lottery participation and entry methods are described in detail in FIGS. 9D and 9E.

And the lottery winnings can be requested (264) in the member management page. When the lottery is requested, the server notifies the database that the lottery payment is requested (268) and instructs the operation of modifying the member DB (270). All work results are checked in real time by the manager and paid in batches to the members' accounts.

FIG. 6 is a diagram illustrating an operation flow of a cache-back service performed when a product order is made through offline.

Referring to FIG. 6, when an offline 100 is defined, a discount store may be viewed as a department store. Here, the difference with the existing department store is that the department stores and selects certain products and sells them. The advantage of such door-to-door sales is that as described above, the customer can recognize the value and provide the service to the customer. In addition, by actually showing and explaining in detail the products that the customer wants or needs, it is easier for the customer to purchase the product.

Recruitment of businesses 200 is one of the requirements for door-to-door sales, the data generated by the business application form 202 is registered in the database 10 of the server. The ID you fill out in the application form will be used to distribute your online shopping mall. Shopping malls sold by such a procedure recognize the value of shopping malls by issuing securities.

Operators will play a pivotal role in facilitating offline growth and require management programs and training (206) for systematic operator management. Operator education can be classified into two categories: operator promotion (208) and product promotion (212). The former operator promotion 208 refers to an existing operator promoting an offline system and driving a subscription to a provider. The latter product promotion (212) by selecting the product suitable for the customer to explain in detail, help the customer to select the product more easily (216).

10A is a catalog used by a business operator to provide product information to a customer. In the catalog, pictures and pictures can be used to identify the product, and the product's characteristics, size, and color are described in detail.

When the product is selected, the customer checks the stock availability 218 and if there is a quantity remaining, the customer writes an order form (220). As shown in FIG. 10B, the order creation screen designates a product delivery address, bank information, recommender, color, size, quantity, and the like.

When the order form 220 is completed, the server determines the presence of the seller (224), the ID search step 226 to identify the seller through the data search of the product DB (20) and sales allowance DB (30) 230) is made. In the data retrieval process, the sales allowance is retrieved and the sales allowance is paid to the seller (228).

When the seller's sales allowance payment is completed as described above, it is determined whether the manager (232), the ID search step 234 to identify the manager to search the data of the product DB 20 and the management allowance DB (40) (238) is made. The management allowance can be retrieved by the manager in the data retrieval process and the management allowance is paid to the manager (236). This process is repeated until an ID with the administrator's authority comes up.

When the payment is completed, the order number is automatically generated 244, and requests the operator and customer lottery ticket to the system server (246). The server retrieves the code number from the database (248) and issues the retrieved code number as a lottery ticket (250). When the lottery ticket is issued, check the stock availability (240) of the goods, if there is no stock, it indicates that there is no stock (242) so that there are no more orders.

In the process of registering one product, there is a process of sales allowance DB 30, management allowance DB 40, customer recommendation setting DB 60, step setting DB (70). When the product stage and points are determined, a stage such as the lottery shopping mall shown in FIG. 8 is automatically formed and stored in the database.

The issued lottery ticket is paid for the customer when the order form is completed, as shown in Figure 10c and can not enter the lottery even if the transaction is completed. However, when the number of the designated number of stages set in the product registration process, the shopping mall displays the deadline (260), and contact the person who has been issued the lottery ticket of the same product in a batch so that there is no disadvantage in the lottery entry .

The lottery participation and entry method provides a page as shown in FIG. 10D in a shopping mall. Here, the information created at the time of product purchase is inputted and compared with the database information of the main server. If the input information is matched, even a non-member may enter the lottery, and the lottery money may be requested (258) from the offline workplace.

When the lottery is requested, the server notifies the database that the lottery payment is requested (260) and instructs the operation to modify the member DB (270). All work results are checked in real time by the manager and paid in batches to the members' accounts.

7 is a diagram conceptually showing an example of the cache-back service proposed in the present invention, and FIG. 8 is a diagram conceptually showing another example of the cache-back service proposed in the present invention.

7 and 8, after a member who has subscribed to the offline and internet shopping mall providing a cash-back service has purchased an item, another member who has purchased the product forms a step of differentially paying points according to a predetermined criterion; Show you 7 illustrates an example of a cache-back service applied to a general shopping mall, and FIG. 8 illustrates an example of a cache-back service applied to a lottery system shopping mall.

In FIG. 7 and FIG. 8, nodes are hierarchically connected by an arc to form a complete binary tree. This data structure is applied to general shopping malls to explain the difference between point payment method of general shopping mall and point lottery system.

이라는 공식이 성립되며, k=0부터 n까지이며 여기서 n은 포인트 단계를 말한다. 예를 들어 n이 1일 때, 노드는 1, n이 2일 때, 노드는 3, n이 3일 때, 노드는 7, n이 4일 때 노드는 15가 된다. 여기서 계산된 노드의 값은 포인트 단계에서 구성된 전체 자녀 노드의 개수이다. 특정단계의 자녀 노드를 구하는 식은

이다. 본 설명에서는 PN으로 정의하였다. 본 발명의 추첨시스템에서 포인트 단계는 당첨등수를 말하며, 등수에서 나온 노드의 값은 포인트 추첨에 응모하여 당첨금을 지급받을 수 있는 포인트 지급금액(SP)을 말한다. 포인트 지급금액(SP)은 일반 고객에게 돌려줄 수 있는 포인트를 포인트 단계로 나누고 나눠진 몫을 지금 현재 노드가 가지고 있는 자녀 노드의 개수를 곱하면 각각의 단계에서 지급받을 수 있는 노드들의 포인트 값이 계산되며, 포인트 지급금액의 계산식은 '(GP / ND) * DD'가 된다. 위와 같은 포인트 추첨시스템의 계산 방식에서는 LOSS 금액이 발생하게 된다. 여기서 발생한 LOSS 금액은 N단계에서 80%, N-1단계에서 20%를 각각의 노드들에게 재분배한다. N단계에서 노드가 받게 되는 포인트(EP)는 'SP +(LP*0.8 / PN)'이고, N-1단계에서 노드가 받게 되는 포인트(DP)는 'SP +(LP*0.2 / PN)'이며, 1단계에서 n-2단계까지의 노드는 SP를 지급받게 된다.7 and 8 form a point step according to the order of purchasing goods. The process of forming a point step is to visit each node in the order of preorder traverse and then enter the positions of each step in order of the root node, the left child node, and the right child node. In the process

Is established, where k = 0 to n, where n is the point step. For example, when n is 1, the node is 1, the n is 2, the node is 3, the n is 3, the node is 7, and the node is 15 when n is 4. Here, the calculated node value is the total number of child nodes configured in the point step. Finding a child node at a particular level is

to be. In this description, PN is defined. In the lottery system of the present invention, the point stage refers to the winning rank, and the value of the node derived from the ranking refers to the point payment amount (SP) which can receive the winnings by applying to the point drawing. Point payment amount (SP) is divided into points that can be returned to the general customer by point stages, and the divided share is multiplied by the number of child nodes currently owned by the node. The point value of the nodes that can be paid at each stage is calculated. The formula for calculating the point payment amount is '(GP / ND) * DD'. The LOSS amount is generated in the point lottery system. The LOSS amount generated here is redistributed to each node by 80% in the N stage and 20% in the N-1 stage. The point (EP) received by the node in step N is 'SP + (LP * 0.8 / PN)', and the point (DP) received by the node in step N-1 is 'SP + (LP * 0.2 / PN)' Nodes from step 1 to step n-2 receive SP.

 Hereinafter, a method of determining the rank for the cache-back service proposed by the present invention and determining the refund amount based on the determined rank will be described in detail.

Rank determination method

Hereinafter, a method of determining an rank for each customer for each product in the cache-back service according to an embodiment of the present invention will be described in detail. In the present invention, it is possible to determine the ranking of each lottery ticket basically through a lottery. Otherwise, the rank may be determined by the purchaser's application order using the following method.

The event for determining the rank proposed in the embodiment of the present invention is repeatedly performed in units of a predetermined sales amount. The unit of the predetermined sales amount means the total number of customers winning in one event, which may be defined differently for each product.

The total number of customers is determined by the total number of ranks awarded in one event. Generalizing this is as shown in Equation 1 below.

Where C _total is the total number of customers who win a single event, and N is the total rank awarded for a single event.

As described above, the equality determination method proposed by the present invention may be generalized as shown in Equation 2 below.

Where n is an equality index and t is an equality determination index.

The equality determination index t may be generalized by Equation 3 below.

Where k is a purchase order number, a is an event count index that designates the number of advanced events, and N is a total number of ranks that can be given through one event.

Therefore, when only the total number of branches of the purchase order, the event count index, and the rank is determined, the rank information corresponding to the information about the specific product from the terminal may be determined.

How to determine your refund amount

Hereinafter, a method of determining a refund amount by rank for a cache-back service according to an embodiment of the present invention will be described in detail. Refund amount determination, which will be described later, may be commonly applied even if the ranking is determined through a draw or the ranking is determined by the method proposed above.

The cache-back service proposed in the embodiment of the present invention is proposed as a method of returning a part of the profit returned to the seller by selling a product. This requires determining the total amount of refunds to be returned to customers in one event per product. The amount to be refunded to the customer may be determined in consideration of the unit price of the product, or may be determined in consideration of the overall profit due to the products sold for one event. The amount of refund to be distributed by rank should be determined based on the total amount of refund.

The easiest way to do this is to divide the total refund amount by the total number of ranks, to determine the amount of refund to be distributed by rank. Such a method would be in the form of dividing the refund amount by rank among the customers constituting each rank.

Generalizing this can be represented by Equation 4 below.

는 x보다 작은 정수이다.Where P _{CASH -BACK} is the refund amount for each customer whose rank is n, T _P is the total refund amount, N is the total number of ranks in one event, and C _n is the total number of customers who can be given rank n. ,

Is an integer less than x.

When the refund amount is determined for each customer by Equation 4, a part of the total refund amount remains. This is called a surplus refund amount. The surplus refund amount is redistributed at an appropriate rate to the refund amount calculated for the customers who win the ranks N-1 and N.

For example, the total refund amount (T _P) is 1,627,886 won, assuming the case of total branches number (N) of a rank is 7, C _n is 1, one such amount is 232,555 won for winning customer discount (P _{CASH - BACK} ), and the discount amount (P _CASH-BACK ) is set at KRW 116,277 for each of the second prize winners with C _n = 2.

Another method of determining the refund amount is to use a cash-back point value assigned to each winning customer.

To do this, cache-back point values are equally assigned to all winning customers. This is called a cache-back point value of 1. The cache-back point value of 1 may be generalized as shown in Equation 5 below.

는 x보다 작은 정수이다.Where SP _n is the cache-back point value of 1 calculated for the customer who wins the rank n, 2 ^N -1 is the total number of winners, C _n is the total number of customers who win the rank n,

Is an integer less than x.

As can be seen in Equation 5, the cash-back point value that can be given to each of the winning customers is calculated by an integer value smaller than the quotient of the number of celestial winners divided by the total number of customers of the same rank. can do.

However, when the cash-back point value of 1 is calculated by Equation 5, a part of the total refund amount is generated as a surplus refund amount. Thus, the value of the one-person cache-back point is adjusted such that 80% of the surplus refund amount is redistributed to customers who win the rank N, and 20% is redistributed to the customers who win the rank N-1.

The total cache-back point value for each ranking may be generalized by Equation 6 below.

Where LP _n is the total cache-back point value calculated for rank n, SP _n is the cache-back point value equal to 1 calculated for customers winning rank n, and C _n is the total number of customers winning rank n to be.

As an example, assuming that the total number of branches (N) of the rank in a single event is 7, the cache-back point value (SP _n ) of 1 calculated by Equation 5 and the total cache calculated by the rank -Shows back point value.

Rank Winning Customers 1 Cash Back-point Total cache-back Total cache-back by rank One One 127 7 127 2 2 63 14 126 3 4 31 28 124 4 8 15 56 120 5 16 7 112 112 6 32 3 (+0.75) 224 120 7 64 1 (+1.5) 448 160 system 127 247 (249.25) 889 889

When the cache-back point value of 1 for the cache-back service is calculated as described above, a discount amount for each winning customer may be calculated using the value. Generalizing the method for calculating the discount amount may be represented by Equation 7 below.

는 x보다 작은 정수이다.Where P _{CASH -BACK} is the refund amount for each customer with rank n, U _{CASH -BACK} is the unit refund amount of the product, N is the total number of ranks in one event, and SP _n is for the customer who wins rank n. A cache-back point value of 1 calculated for

Is an integer less than x.

As described above, the present invention proposes a cache-back system and a cache-back method in which a seller caches back a certain profit for an online customer or an offline customer, thereby increasing the purchaser's motivation to purchase a fixed customer without additional promotion. There is an advantage to be secured. It can also lead to voluntary promotion of buyers.

In addition, a large amount of merchandise can be sold, allowing the producer to purchase the product at a low price, so that the retailer's profit can be bought at a lower price than the buyer, thereby securing high profits. In addition, it is possible to reduce costs and costs in the producers, so that they can supply goods at low prices. It can secure fixed customers and sell in bulk, reducing the distribution stage. As a result, both producers, sellers and consumers can generate more profits and lead smooth product distribution.
