a database 430 for storing the customer's receipt information, the customer's summary receipt information, and the printed receipt information;

After receiving the receipt information from the payment device 200 or the receipt issuing device 100, and receiving the customer's identification information from the payment approval server 600, compare it and match, the customer's receipt information in the database ( 430), generate and store summary receipt information or printed receipt information using the receipt information, and a server 420 that provides the summary receipt information or printed receipt information in response to a request from the device for inquiry include

An electronic receipt transmission unit 410 for transmitting the receipt information transmitted to the printer 300 to the server 420 is added to the one payment device 200 or the receipt issuing device 100 .

The payment device 200 is a device for requesting payment approval, and may be a POS device or a CAT (credit card terminal) device during face-to-face payment.

And, in the case of non-face-to-face payment, it may be a payment server that provides an on-line payment window (Payment Gateway screen, etc.).

Information transmitted from the payment device 200 to the payment approval server 600 of the card company at the time of a payment approval request is as follows.

For example, when requesting credit card approval, credit card information including card number, expiration date, and number of installment months, merchant information (merchant number, CAT terminal number, etc.) and payment information (payment amount, VAT, etc.) It is transmitted to the approval server (600).

In addition, when a cash receipt approval request is requested after cash calculation, customer information (phone number, business registration number, etc.), merchant information (merchant number, CAT terminal number, etc.), and payment information (payment amount, VAT, etc.) are sent to the payment approval server (600 ) is sent to

In addition, when a point payment approval request is made, customer information (membership number, phone number, etc.), merchant information (merchant number, etc.), and payment information (payment amount, VAT, etc.) are transmitted.

Then, the payment approval server 600 returns the processing result information for the payment approval request to the payment device 200 .

At this time, during normal approval processing, the payment approval server 600 returns payment approval related information (card approval number, cash receipt approval number, accumulated point value, etc.).

On the other hand, during the approval rejection processing, the payment approval server 600 returns error-related information (error number, /error message, etc.).

The receipt issuing device 100 is a device for generating receipt information based on payment information, and may be generally included in the payment device 200 .

here, Receipt information includes merchant information (business registration number, representative name, address, contact number, POS number, cashier number, receipt issuance time, etc.), purchase information (product name, unit price, quantity, total amount, discount amount, VAT amount, etc.), customer Payment method information (card number, phone number, member number, etc.), payment information (payment amount, approval number, etc.), command information for printer 300 control (not printed on paper, but included for the purpose of controlling the printer 300) commands, for example, horizontal/vertical text enlargement, right/left/center alignment, paper cutting, etc., which are representative of EPSON's ESC-POS command set).

The receipt printer 300 is a device that prints receipt information as a paper receipt as shown in FIG. 5 , and may be implemented as a single device by being combined with the payment device 200 and/or the receipt issuing device 100 if necessary. For example, it can be implemented as a CAT terminal. It can also be printed as a file if necessary.

The payment approval server 600 is a server such as a credit card company or a check card company, and may perform functions such as credit card payment approval, cash receipt issuance approval, point payment approval, and the like.

The electronic receipt transmission unit 410 (referred to as Receipt Transmit Module, RTM) blocks the receipt information transmitted from the receipt issuing device 100 to the receipt printer 300 so as not to be printed, and instead of the receipt to the server 420 The information is transmitted, and it can be implemented in the form of an independent program or module inside the receipt issuing device 100, and can be implemented as a separate external device, and the existing S/W operating inside the receipt issuing device 100 is used. It may be modified to include the RTM function.

The inquiry device 430 is an information terminal device that requests and receives receipt information from the server 420 and displays it on a screen, and may be a smartphone, a tablet, a laptop computer, or the like.

Referring to Figure 2, the database 430,

Receipt DB 431 for storing the customer's receipt information, the customer's summary receipt information, and the printed receipt information;

and a consumption information DB 432 that stores consumption information of all customers based on the usage history of each customer.

Referring to Figure 3, the server 420,

an information receiving unit 421 for receiving receipt information from the payment device 200 or the receipt issuing device 100;

After receiving the customer's identification information from the payment approval server 600 and comparing it with the receipt information, it is stored in the database 430 as the customer's receipt information, and summary receipt information using the receipt information Or a receipt processing unit 422 to generate and store printed receipt information;

an information providing unit 423 for providing the summary receipt information or printed receipt information in response to the request of the inquiry device 700;

and a consumption information processing unit 424 for generating consumption information of all customers based on the usage history of each customer and storing the consumption information in the consumption information DB 432 .

When the receipt processing unit 422 receives the customer's identification information from the payment approval server 600 and compares it with the receipt information to match, it may be stored in the database 430 as the customer's receipt information,

If necessary, the customer's identification information is received from the payment approval server 600 and stored, and the customer's receipt information is also stored in the database 430, and a comparison operation may be performed later.

If necessary, the receipt transmitter (RTM) may also generate a summary receipt.

In addition, the server and database may be included in a payment device or a receipt issuing device, such as a receipt transmission unit (RTM).

The operation of the electronic receipt service system according to the first embodiment of the present invention having such a configuration will be described as follows.

First, when a user requests payment after purchasing a predetermined product or using a service online or offline, the payment device 200 requests payment approval to the payment approval server 600 (S10).

Information transmitted from the payment device 200 to the payment approval server 600 of the card company when a payment approval request is made is as follows.

For example, when requesting credit card approval, credit card information including card number, expiration date, and number of installment months, merchant information (merchant number, CAT terminal number, etc.) and payment information (payment amount, VAT, etc.) It is transmitted to the approval server (600).

In addition, when a cash receipt approval request is requested after cash calculation, customer information (phone number, business registration number, etc.), merchant information (merchant number, CAT terminal number, etc.), and payment information (payment amount, VAT, etc.) are sent to the payment approval server (600 ) is sent to

In addition, when a point payment approval request is made, customer information (membership number, phone number, etc.), merchant information (merchant number, etc.), and payment information (payment amount, VAT, etc.) are transmitted.

Then, the payment approval server 600 approves the payment, and generates a payment approval number. Then, the payment approval server 600 transmits the payment approval number to the server 420 (S20).

At this time, during normal approval processing, the payment approval server 600 returns payment approval related information (card approval number, cash receipt approval number, accumulated point value, etc.).

On the other hand, during the approval rejection processing, the payment approval server 600 returns error-related information (error number, /error message, etc.).

Next, the payment device 200 receives the payment approval number, and the receipt issuing device 100 generates receipt information (S30).

Then, the electronic receipt transmission unit 410 collects (blocks) the receipt data transmitted to the printer 300 in the middle and outputs it to the server 420 (S40). For example, in the case of the printer 300 of the serial communication method, it can be implemented as a virtual serial port driver method, and in the case of the printer 300 of the USB communication method, it can be implemented as a virtual window printer driver method. In addition, in the case of printing in file format, the print result file itself can be collected.

In the embodiment of the present invention, there is no need to modify the existing receipt issuance program inside the receipt issuing apparatus 100, thereby reducing cost and period. Most current e-receipt services require modification of existing programs. In addition, it is also possible to implement a method of directly receiving data by modifying the program of the receipt issuing device 100 .

After the information receiving unit 421 of the server 420 receives the receipt information from the payment device 200 or the receipt issuing device 100, the receipt processing unit 422 of the server 420 allows the customer to inquire the data. After processing the receipt information, it is stored in the receipt DB 431 of the database 430 (S50).

In this case, the server 420 may store the collected entire receipt data in the receipt DB 431 of the database 430 . In this case, the same receipt as the actual receipt as shown in FIG. 5 may be printed using this information.

In addition, the server 420 extracts only essential items (eg, trade name, payment time, payment amount, payment method, payment approval number, receipt serial number, etc.) and may store information in the form of a summary. In this case, the summary receipt data as shown in FIG. 4 may be printed. In this case, it is also possible to print and transmit separate receipt unique identification information together with barcodes/QR codes, etc. to easily inquire the entire receipt data later.

As such, printing a summary can significantly reduce the consumption of printing paper compared to printing the entire receipt every time, thereby reducing social costs and reducing carbon emissions.

Thereafter, the user can inquire the receipt information by using the inquiry device 700 (S60). That is, the user can search for a required receipt at any time by inputting a search term such as name/location/time/payment amount/payment method into the inquiry device 700 .

In addition, if there is receipt information already received in the summary form from the information providing unit 423 of the server 420, the payment approval number, receipt serial number, or barcode or QR code information printed on the summary receipt is utilized. This makes it easy to find the entire receipt contents.

On the other hand, when the user goes through the first personal authentication step through the personal authentication server 420 (S70), automatic search is possible without entering a search word.

Here, the initial authentication uses a personal authentication service such as a public certificate, mobile phone authentication, credit card authentication, or the like, or through a method such as directly input by the customer, after acquiring the required customer personal information, the payment approval server 600 is After safely transmitting the requested personal information items (resident registration number/phone number/credit card number, etc.) (S80), the unique identification information assigned to the customer (for example, a series of no special meaning regardless of exposure to the outside) number, etc.) is well known in the art as a method of receiving and recording a reply, so a detailed description thereof will be omitted.

When personal authentication is complete, access the website affiliated with this service using the inquiry device 700 or run the inquiry app, all receipts issued to you using your own unique identification information recorded through personal authentication can be searched automatically. At this time, when the payment approval number is transmitted to the payment device 200 by the payment approval procedure through partnership with the corresponding payment approval server 600 manager, the server 420 also receives the payment approval number and the corresponding customer By transmitting the unique identification information together (S90), an automatic search function may be performed. At this time, the payment approval server 600 may transmit the customer's unique identification information not directly to the server 420 but also through the payment device 200 or the receipt issuing device 100 or the receipt information transmission unit 410 . .

If necessary, the customer's unique identification information is transmitted to the server 420 through the path indicated by S90, but in some cases, via one or more of the payment device 200, the receipt S/W 100, and the RTM 410 It may be transmitted to the server 420 .

If necessary, when the electronic receipt is issued, the payment approval server 420 may notify or transmit the electronic receipt to the inquiry device 430 by SMS or push message immediately. Also, RTM can be configured to send SMS or push message to the device for inquiry.

And, when the receipt data is transmitted from the receipt information transmitting unit 410 to the information receiving unit 421 of the server 420, several items (trade name / payment amount / item information, etc.) included in the receipt data are parsed and extracted. If you send it out as a separate item, you can efficiently search it when customers inquire about receipt data.

In addition, from the receipt information transmitting unit 410 to the information receiving unit 421 of the server 420 When sending receipt information, it uses the printer control command (ESC-POS) included in the receipt data to generate receipt picture data in the same form as a paper-printed receipt, and encrypts it or applies a digital watermark. If it is transmitted, it is possible to effectively prevent forgery and falsification at a much lower cost than methods such as blockchain when inquiring and utilizing receipt data.

Here, this process of converting picture data may be performed in the receipt information transmission unit 410 , but may also be performed in the server 420 or the inquiry device 430 .

If the electronic receipt can be viewed using the image data (jpg, png, etc.) that has been forged and tampered with, it is possible to find the electronic receipt anytime and anywhere with a web browser, etc. In this format, it is possible to send and receive safe receipt data simply and easily, maximizing utilization.

In general, when sending receipt data, customer personal information (phone number, member number, e-mail address, etc.) must be transmitted at the same time, so that the customer can register personal information in advance, register for electronic receipt service, or register for membership. shall.

However, in the embodiment of the present invention, the electronic receipt issuance service can be performed with only the transmitted receipt data without such cumbersome transmission of additional information or a preliminary preparation procedure.

In addition, in the embodiment of the present invention, the affiliate store does not need to go through a separate franchise contract or subscription procedure for the electronic receipt service.

If necessary, the consumption information processing unit 424 generates consumption information for the entire customer based on the usage history of each customer, stores the consumption information in the consumption information DB 432 , and then retrieves it with the inquiry device 700 . do.

For example, the consumption information processing unit 424 may organize and provide each customer's consumption information for each store and period.

Therefore, the user can use such information for a household account book or tax return without separately managing receipts.

In particular, even if you use various stores and use various cards, you can use your consumption information as one data.
