If necessary, the communication unit 240 may be provided, and advertisements received from the server 110 may be displayed.

The operation of the donation service system using a QR code according to an embodiment of the present invention having such a configuration will be described as follows.

First, the present invention secures a quantity by receiving a first donation in kind from a company such as an open market (or an online shopping mall), and outputs advertisements or promotional content for the corresponding product through the display device 300 installed in a public place. The application money for the issuance of exchange coupons or first and second discount coupons for the item is received secondarily, and the exchange coupon is issued only to the winner among the secondly donated user members, and to the remaining non-winners. A first discount coupon (one item commerce) is issued for the relevant item so that the application amount is compensated.

In addition, a second discount coupon having a higher discount rate than that of the first discount coupon is provided to a user who wants to purchase the discount coupon immediately without drawing lots.

In addition, since users may visit the company that provided the corresponding product to make additional purchases, the donation may be positive for sales from the company's point of view.

For example, when Lotteria donates a hamburger, organizations such as the Red Cross issue a donation receipt to the company and provide a mobile exchange coupon or discount coupon to the customer who made the donation.

If necessary, users receive a donation of 500 won to 1,000 won, and a hamburger exchange coupon or 1,000 won discount coupon is provided.

In addition, a hamburger voucher can be sold at a discount of 1,500 won to users who choose to purchase at a discount rather than a donation.

In this way, from the standpoint of the company, donation receipts can be used for tax settlement as well as promotion and sales.

Therefore, in an embodiment of the present invention, all items such as pizza, chicken, coffee, stationery, clothing, and electronic products are donated in kind, tax settled, and publicized, and customers can come back to the store to increase sales.

To this end, in the present invention, a vudaus display device is installed in a subway station or a street government building.

The display device 200 displays the QR code on the display unit 210, and when a plurality of users are detected, the QR code is enlarged and displayed. Therefore, the user can easily recognize the QR code with the user terminal 300 . If necessary, it is also possible to request the QR code to the display device in the form of a sticker.

In addition, the display device 200 displays an advertisement of a company that provided a donation item.

Through this process, the user terminal 300 accesses the server 110 and the following process will be described in detail.

4 is an operation flowchart of a donation service method using a QR code according to an embodiment of the present invention.

Referring to FIG. 4 , the user terminal 300 executes a specific URL through contact with the QR code to access the server 110 (S410).

Then, the server 110 provides a web page for selecting a donation or discount purchase.

If necessary, the member management unit 111 may perform member authentication with reference to the user member information DB 121 and the corporate member information DB 122 . The corporate member may provide the in-kind information to the server using the corporate terminal 400 .

The user selects donation or discount purchase through the user terminal 300 , and the payment processing unit 112 of the server 110 receives the selection of donation or discount purchase from the user terminal 300 ( S420 ).

When the donation is selected (S430), the payment processing unit 112 of the server 110 receives the donation from the user terminal 300 (S440).

In this case, the payment process is as follows. When payment request information is received from the user terminal 300 , the server 110 requests payment approval from the card company system 810 or the banking system 820 for the corresponding amount.

At this time, when the payment method is a credit card, the payment processing unit 112 of the server 110 requests payment approval from the card company system 810 with the detailed information,

When the payment method is a debit card or a cash card, the payment processing unit 112 of the server 110 requests the bank system 820 to approve the payment using the detailed information.

Then, the card company system 810 or the bank system 820 approves the payment with the payment history information.

Then, when payment approval information and approval history information are received from the card company system 810 or the banking system 820 , the payment processing unit 112 of the server 110 transmits the information to the user terminal 300 . Then, the payment processing unit 112 processes the cash receipt by using the phone number of the user terminal 300 when the sales occur with a cash card or a check card. In this case, if necessary, the cash receipt processing details may be transmitted to a tax system such as the National Tax Service.

Thereafter, when the payment is completed, the lottery processing unit 113 of the server 110 performs a lottery (S450). Such a lottery method may be implemented to have an algorithm that increases the probability of winning the exchange coupon as the amount of donation increases. For example, if the minimum donation amount of 100 won is paid, the probability of winning the exchange coupon is 1%, whereas if the donation amount of 200 won is paid, the probability of winning the exchange coupon is 2% and the donation amount of 300 won When payment is made, the winning probability of the exchange coupon is 3%, and when the donation amount of 400 won is paid, the winning probability of the exchange coupon is 4%. Therefore, it can induce a little more donation amount. If necessary, the winning probability may be the same regardless of the amount of donation.

On the other hand, it may be implemented so that the number of coupons ratio, which is the ratio of the number of exchange coupons and the number of discount coupons, is determined according to the type of donation. For example, if the number of coupons that can receive company A's hamburger for free or in-kind donation is determined to be 1,000, the exchange coupon will be 100 out of 1,000 and the discount coupon will be basically determined as 900 out of 1,000. In this case, the coupon number ratio has a ratio of the number of exchange coupons: the number of discount coupons = 100:900 = 1:9. These contents can be variously modified, and can be variously modified to strategically induce consumers to the store according to the type of donation in kind.

Next, the coupon providing unit 114 of the server 110 provides a product exchange coupon or a first discount coupon to the user terminal 300 according to the lottery result (S460). In this case, the product exchange coupon or the first discount coupon includes location information of a store where the coupon can be used.

On the other hand, when discount purchase is selected (S430), the payment processing unit 112 of the server 110 provides product information from the product information DB 125, and then selects the product from the user terminal 300 (S470), Receive payment (S480). The payment processing unit 112 of the server 110 issues a cash receipt when paying with a cash card, check card, etc., and uses the phone number of the customer terminal when processing the cash receipt. It is very convenient to process cash receipts. In this case, the cash receipt issuance information may be stored in the cash receipt information DB 124 .

Next, the coupon providing unit 114 of the server 110 provides a second discount coupon for the selected item to the user terminal 300 (S490). In this case, the second discount coupon includes location information on a store where the coupon can be used. And, it is characterized in that the discount rate of the first discount coupon is smaller than the discount rate of the second discount coupon.

Thereafter, the user uses the exchange coupon, the first discount coupon, or the second discount coupon received by the user terminal 300 ( S500 ).

For example, the user selects a location guide or location information included in the exchange coupon, the first discount coupon, or the second discount coupon.

Then, the control unit guides the route from the current location to the store using the location information included in the coupon.

Accordingly, the user can conveniently visit the store and use the coupon.

Meanwhile, the coupon providing unit 114 stores and manages the provision of coupons in the coupon information DB 123 .

In this embodiment of the present invention, the user terminal 300 can conveniently use the donation service by simply attaching the QR code to a predetermined place.

In addition, in an embodiment of the present invention, a low-priced display device is installed in a public place and a QR code is displayed on some or all of the display device, so that the user can more easily use the donation service.

In addition, in an embodiment of the present invention, when an exchange coupon is received by the user terminal 300 , it is possible to guide the user to a store where the exchange coupon can be used.

In addition, in an embodiment of the present invention, it is possible to automatically issue a donation receipt for a company that has made a donation such as in kind.

The embodiment of the present invention described above is not implemented only through the apparatus and method, and may be implemented through a program for realizing a function corresponding to the configuration of the embodiment of the present invention or a recording medium in which the program is recorded.
