Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus and a method for batch processing offline shopping using a user terminal,

In particular, the present invention relates to a technique for collectively processing offline shopping by a user carrying a terminal, and in particular, a user who visits an offline store such as a mart or a bookstore directly selects a product displayed on the display using the user terminal, And more particularly, to an apparatus and method for batch processing of offline shopping that can be delivered to offline sellers at a time.

In the conventional offline shopping process, the customer selects a product to be purchased and places it in a shopping cart or a cart and moves to a fixed counter. The staff at the counter then scans each of the products one at a time through a bar code scanner that is interfaced with a POS (Point of Sales) system. In addition, the process of obtaining information about the member, the payment method, and the desire for delivery from the customer after the bar code of the product is scanned also causes waiting time. At each counter, waiting time occurs due to this procedure, and there is a queue of customers at each counter.

On the other hand, a bar code is a code made by combining black and white bars of different thickness, which is designed to be readable by a computer, and is mainly printed on the package of the product. This type of barcode is defined as a linear or one-dimensional barcode. The bar codes used in Korea are used as KAN codes. KAN bar codes are divided into two types, standard type and abbreviated type. The standard type consists of 13 digits, the first three digits are the country code, the last four digits are the manufacturer code, the next five digits are the commodity item code, and the last one verifies that the numeric and bar- It is a number. The abbreviated form consists of 8 digits, with the elements in the same order as the standard type being reduced to three digits, three digits, one digit, and one digit.

The QR code is a two-dimensional bar code in the form of a matrix representing information in a black and white plaid pattern. This code is mainly used in Korea, Japan, the United States, and the United Kingdom. The official name is derived from the registered trademark "Quick Response" of Denso Wave, and it is called QR code. This QR code overcomes the capacity limitation of a conventional one-dimensional bar code and has a two-dimensional bar code that extends the format and contents of the bar code. It is usually scanned with a digital camera or a dedicated scanner. While the conventional one-dimensional barcode can store only numerical information of about 20 characters, the QR code has a maximum of 7089 characters, a maximum of 4296 characters (ASCII), a maximum of 2953 bytes for binary (8 bits), and a maximum of 1817 characters for Chinese characters And it is superior in recognizing speed, recognition rate, and resilience than a one-dimensional bar code.

Based on the above-described element technologies, the following prior art documents disclose a configuration in which a virtual shopping cart is implemented using a smart phone and the shopping plan established in conjunction with offline shopping is checked, In the process of settlement of the offline shopping, the shopping plan which the user has written is not directly linked.

Before explaining the embodiments of the present invention, the technical means adopted by the embodiments of the present invention will be outlined to solve the problems occurring in the offline shopping process.

As mentioned above, the existing shopping process inquires about the member, the payment method, the desire of the delivery, and the process of inputting the personal information and the barcode scanner connected to the POS terminal to scan the goods one by one. This leads to an increase in the queue length of the calculation unit or an increase in the calculation time.

In order to solve such a problem, embodiments of the present invention described below set / store user information such as whether a member is a member, a payment method, a desire to be delivered to a user terminal such as a smart phone in advance, By passing it to the POS system, the unnecessary procedures performed by the POS and the staff are omitted. In addition, the user can directly barcode the product to the user terminal, collect the product information to be settled, and transmit the collected product information to the POS terminal, thereby reducing the time for the employee to scan the goods to be settled through the POS terminal. In addition, the embodiments of the present invention perform user authentication in order to protect user information or payment information that should not be exposed to the employees of the mart or even a third party in transmitting the information collected through the user terminal to the POS terminal .

To this end, embodiments of the present invention store user information such as whether a member is a member, whether a mobile payment is desired, a desire for delivery, personal information, and the like in advance in a smart phone, and store the barcode and the product number of the product, And then generates user information and product information together with the encryption information in one QR code. By recognizing the generated QR code in the POS terminal, the waiting time of the existing shopping process can be effectively reduced.

In order to implement embodiments of the present invention from the viewpoint of configuration, a bar code used for product recognition, a smart phone (a camera or a bar code scanner) used by a customer to scan a product, A barcode of the scanned products, a QR code used to represent the customer information as one piece of information, and a QR code for proceeding with settlement POS software that can scan, QR code, information processing and settlement is required.

Hereinafter, embodiments of the present invention for solving the above-mentioned technical problems will be described in detail with reference to the drawings. In the following description and the accompanying drawings, detailed description of well-known functions or constructions that may obscure the subject matter of the present invention will be omitted. It is to be noted that the same components are denoted by the same names and reference numerals as possible throughout the drawings.

1 is a view showing a basic idea of a shopping batch processing technique to be implemented by embodiments of the present invention in an offline shopping process.

First, a user scans a product one by one in the process of putting a product selected by the user into his or her shopping cart using his / her user terminal 100. In this process, a user scans a barcode of a product to be purchased, inquires information on the product, and accumulates the information on the smartphone. The barcode scan can be performed by the user's smartphone application. The information of the scanned product is stored in the user terminal 100, and more specific product information may be acquired by inquiring the product server. In addition, the user terminal 100 preferably sets and stores individual user information such as membership information, payment information, or delivery status in advance. In addition, the user terminal 100 is equipped with an OTP authentication module in order to protect payment security and personal information. Generates an OTP value, conceals information through an encryption process or a concealment process to protect the generated OTP value, and combines the obtained product information and user information together to generate a single QR code.

When the QR code is displayed on the screen of the user terminal 100, the employee uses the QR code scanner interlocked with the POS terminal 200 to transmit all the information (encryption information, product information, and user information) Receive. That is, the shopping for the individual goods is processed in a batch manner. Then, the POS terminal 200 extracts encryption information by parsing the scanned QR code, and inquires the OTP authentication server 300 for authentication. If the authentication is successful, the POS terminal 200 proceeds the settlement based on the remaining information (product information and user information) to end the shopping process.

FIG. 2 is a flowchart illustrating a method of processing a batch of offline shopping according to an embodiment of the present invention, from the viewpoint of a user terminal, including the following process.

In step S110, the user terminal acquires product information by scanning at least one product that the user intends to purchase. In this process, the user may scan at least one item to be purchased, inquire information of the goods scanned in the goods server, and add the goods information including the goods name, quantity and price to the goods list to be purchased. After obtaining the product information, you can adjust the number of each product or proceed with the procedure such as cancellation of purchase, and you can check the total purchase amount.

This process is performed by the POS terminal and the staff fixed in the existing offline shopping process. However, in the embodiments of the present invention, the user can perform the procedure at the same time as selecting the goods, All product information should be delivered to the POS terminal at once by QR code. This will simplify the existing billing process, which allows an employee to retrieve items and scan product bar codes on a daily basis.

Referring to FIGS. 3 and 4, a process of inquiring product information will be described.

3 is a diagram illustrating a structure of 'product information' implemented in a database table of a shopping mart. A table in which merchandise information is stored in a shopping mall database may include information such as a bar code number, a name, a price, . For example, assuming that the user inquires the commodity information of the 'commodity 1' in the 'commodity information' table of FIG. 3, the commodity information inquiry process of the commodity 1 is as follows.

First, the smartphone sends "1 1111123456789", the bar code number of cookie 1, to the server of the mart. The server retrieves the merchandise information from the database of the mart using the number of bar codes received. In the example of FIG. 3, the bar code of cookie 1 is "1111123456789 ", so that the server can obtain information on the corresponding bar code, name, and price, and the inquiry result may be" 1111123456789, cookie 1, 2000 ". Now, the query results are sent to the smartphone. Therefore, the value received by the smartphone is "1111123456789, cookie 1, 2000".

FIG. 4 is a screen illustrating a product list in which a product information of 'Sweets 1' is added in a user terminal. The product information obtained after inquiring a database of a shopping mart is output to a smartphone screen, I assumed the situation. On the screen, the total price according to the name, the number, the price, and the number of each product can be output on the screen. The output information can be modified after the user confirms the product number. If the user does not want to purchase, Can be canceled. The barcode can be obtained when scanning a product with a barcode scanner, and the name and price are obtained as the result when the barcode database is searched.

Now let's return to the overall flow chart of Figure 2 again.

In step S120, the user terminal combines the One Time Password (OTP) value with the random number sequence, divides the OTP value according to a specific rule, and distributes the OTP value to the random number sequence to generate encryption information. The OTP value may be generated by an OTP generation module included in the user terminal or may be an OTP value generated through an OTP generation device outside the user terminal, . ≪ / RTI > For example, the OTP generation module in the user terminal may be implemented as an application-based software such as 'Smart OTP', and the OTP generation device outside the user terminal may be implemented through a conventional OTP generator, And inputting the OPT value to the user terminal. The method of generating the encryption information will be described later in more detail with reference to FIG.

In step S130, the user terminal generates one QR code that combines the encryption information generated in step S120, the user information previously stored for payment of goods, and the product information obtained in step S110.

Here, the user information may include at least one of whether or not a payment is made through the user terminal or a delivery request, including member information. The user can set his / her shopping information in advance on the smartphone without any restriction on the location. This can simplify the settlement procedure by omitting the procedure of inputting the member information, which was performed in the payment process of the existing process. It is desirable that the contents set by the user are implemented so that the user information can be modified even during the shopping when necessary.

The user can select a desired shopping method among the selected items, and the selected items may include member information input, mobile payment, and delivery service. In addition to picking a product, the user makes various choices for shopping. For example, you can choose whether to offer discounts and benefits for members, whether to sign up for a membership, what to do with your payment method, whether to get a shipping service, It selects the necessary items according to the method. In the case of conventional offline shopping processes, almost all of these user selections were performed at the payment and delivery stages, which resulted in delays in the payment procedure. Therefore, according to the embodiment of the present invention, the user can select the same day shopping method with his / her smartphone before starting the shopping, thereby reducing the time for the user to inquire and select the employee in the payment procedure. Items to be selected by the user include whether they are members or not, and mobile payment, which is a new payment method for paying a payment with a user smartphone, can also be included in the item.

If the user selects the shopping method, the user must input the user's personal information required by the selected item. The information that the user needs to input includes a mobile phone number, a name, an address, and a shopping limit. The personal information of the user inputted here is used to provide discounts and benefits to members, a process of re-transferring the total amount from the POS terminal in the case of mobile payment, and an address to be delivered at the time of delivery. Therefore, the process of inputting the user's personal information such as the mobile phone number in the payment procedure of the existing offline shopping process can be omitted, and the settlement procedure can be further simplified. It is preferable that the information to be inputted by the user is determined according to the shopping method selected by the user in advance and that the user can proceed to the next step only after inputting the required items. The shopping limit in the user information is the maximum value of the total amount of goods to be paid by the user, which helps the user to do the right shopping without overage. Once the information is entered, keep it in the smartphone application. If the user does not select anything in the desired shopping method selection process, it means that there is no shopping method, so user information need not be input separately. Therefore, in such a case, the user does not need to input the personal information and proceeds with shopping immediately.

Now, it is possible to input user information such as whether or not the user is a member, whether it is a mobile payment, a desired delivery service, personal information of a user, and the like at a time without asking the user for mileage accumulation, payment means, Ready to process.

In order to include information in the QR code, a module for creating the QR code and an algorithm for defining how to store the encryption information, the user information, and the goods information to be paid are required. Through this algorithm, the encryption information, the user information, and the goods information to be paid are converted into a single character string, and this character string is generated as a single QR code through the QR code generator. Accordingly, the process of generating the QR code may include connecting the encryption information, the user information, and the product information using a delimiter, and converting the connected string into a QR code according to a QR code generation rule, And instructs the QR code to be parsed based on the delimiter.

In step S140, the user terminal displays the QR code generated in step S130 on the screen, thereby causing the POS (Point Of Sales) terminal to guide the settlement through the QR code scan. That is, the user terminal transmits product information on at least one or more goods to be purchased by the user using the one QR code displayed on the screen to the POS terminal . The POS terminal parses the scanned QR code to separate encryption information, extracts an OTP value from the extracted encryption information using the specific rule, and extracts the extracted OTP value The POS terminal can extract the user information and the product information in the QR code and proceed with payment of goods.

In addition, the user can confirm the goods information to be paid out by outputting the previously parsed information to the screen of the POS terminal, and the user who has confirmed that the goods information to be paid is not abnormal, performs payment and delivery service through POS and mobile POS . Since the contents of billing and delivery are based on the parsed user information such as membership benefits, mobile payment, and delivery service, employees can skip the time to ask user questions and input user information in the existing process . After the payment is completed, the receipt is obtained. The delivery service can be provided through the output of the delivery label and the visit to the counter.

Now, a technique of generating encryption information adopted by embodiments of the present invention will be described in detail with reference to FIG. In the embodiments of the present invention, the OTP value itself is encrypted / concealed by distributing the OTP value to a random number column. In the existing OTP authentication system, the output OTP value is directly inputted to the server, but it has a weak point that the OTP value is directly exposed. Therefore, here we distribute the OTP values to a numeric string of random numbers to create new encrypted data and send the data to the server. Even if the value transmitted through this process is exposed, it is difficult to directly extract the original value of OTP. In order to distribute the OTP value to the random number sequence, specify the interval between the OTP numbers by using the operation expression that extracts the prime number and the squared value of the extracted prime number.

5 is a flowchart illustrating a process of generating encryption information (S120) in the batch processing method of FIG. 2 according to an embodiment of the present invention.

In step S121, the user terminal separates the OTP value into digits. Here, it is assumed that the OTP value is already secured by the OTP value generation means inside or outside the user terminal. The generated OTP value is assumed to be 6 digits.

In step S122, the user terminal specifies an interval between the OTP values separated by the digits by using an operation expression for extracting a prime number corresponding to each digits separated through the step S121 and the squared value of the prime extracted.

More specifically, an arbitrary N-key is set, and the number of digits is discriminated. First, it is determined whether the value of the first digit of the generated OTP is an even number or an odd number. If the discriminated value is an even number, it is symmetric with the N-key value in Table 2. In the case of odd number, it is symmetric with the N-key value in Table 3. [ The value between 0 and 9 of the OTP has one of the N-key values in Table 1 according to the symmetry reference. The symmetry value of the N-key can be changed to any value depending on the environment.

The N-key of the symmetric OTP is substituted into the OTP dispersion equation according to the following Equation 1 and converted into a decimal value as shown in Table 4. [

Equation (1) represents a function for obtaining the decimal value obtained by converting the N-key.

Table 5, which is a value obtained by squaring the converted decimal value according to Equation (2), is a calculation of the number of random numbers between OTP positions.

Represents the number of random numbers in the OTP sequence.

In step S123, the user terminal distributes the OTP values separated by the digits in the random number sequence according to the interval specified in step S122, and sets the OTP values as encryption information. Assuming that OTP values are distributed in the random number sequence according to the above algorithm, if the generated OTP is as shown in Table 6.

의 값인 OTP 자리 사이의 난수의 개수 529로 계산된다. 첫 번째 자리 수인 7의 다음 529자리 수 뒤에 OTP의 두 번째 값인 1로 대치된다. 위와 같은 방식으로 9까지 OTP 6개의 값을 배열에 대치한 뒤 완성된 숫자 열을 생성한다. 생성된 OTP 값 '711469'를 OTP 분산 기법을 이용하여 난수 숫자 열에 분산시킨 암호화 정보의 예시는 도 6과 같다.First, a certain number of random numbers are generated. At this time, it is desirable to determine the number of random numbers in the usable area in consideration of the remaining information (user information and product information) to be loaded in the QR code. Then, the first value of 7 in the OTP is replaced with the value of the first digit in the column. 7 with the value of the N-key symmetric to

The number of random numbers between OTP sites is 529. [ The first 528 digits of the 7th digit are replaced by the second value of the OTP. In this way, we replace the 6 values of OTPs up to 9 with the array and generate the complete sequence of numbers. An example of the encryption information obtained by dispersing the generated OTP value '711469' in the random number sequence using the OTP dispersion technique is shown in FIG.

Now, among the three pieces of information to be included in the QR code, a method of converting the remaining information excluding the encryption information (user information and product information) into a character string will be sequentially described.

The user information included in the QR code includes information on the user shopping manner set by the user, and mobile phone number, name, and address, which are personal information of the user. The goods information to be paid may be a barcode and the number corresponding to the barcode. Personal information such as mobile phone number, name, and address is used for member benefits, mobile payment, and delivery service according to the shopping method set by the user.

FIG. 7 is a diagram illustrating a list of information constituting one QR code, and includes information related to user information and information related to goods to be paid.

8 is a flowchart illustrating an algorithm for converting user shopping method information into a character string. The user shopping method information includes information on whether or not the shopping methods selected by the user are selected in advance. Whether or not the user selects the shopping method is converted into a string by separating the selection and non-selection so that it is applied to each shopping method. For example, if the user has selected a delivery service, enter a delimiter character indicating the desired delivery service in a character string, and otherwise input a delimiter character indicating that the user does not desire. Other shopping style items are processed in the same way. Here, the converted delimiters are scanned and QR code is parsed through a scanner connected to the POS terminal, and the shopping mode set by the user is transmitted to the POS terminal, which is reflected in the settlement and delivery procedure.

For example, in FIG. 8, 'Y' means 'member delimiter character', 'mobile settlement delimiter character', 'delivery desired delimiter character' to Y, which means that the corresponding item is set, It is assumed that the separator for distinguishing the non-member separator character, the mobile payment non-desired separator character, the 'shipping non-desired separator character' as the 'N' If the user wishes to shop as a member and does not wish to pay for mobile and wishes to be shipped, each delimiter will be 'Y', 'N', 'Y' - The string result for the string conversion algorithm is "YNY /".

9 is a flow chart illustrating an algorithm for converting user personal information into a string. The user's personal information is the personal information of the user entered in accordance with the shopping method selected by the user in advance, for example, a mobile phone number, a name, an address, and the like. The algorithm checks whether the mobile phone number, the name, and the address, which are personal information of the user, are input and converts it into a character string. If there is an input, take the value of each entry and add one delimiter. If there is no input, treat it as missing and add a delimiter. The algorithm of FIG. 9 uses the string used in the 'user shopping method information-string conversion' algorithm of FIG. 8 described above.

For example, assuming that "No value" is null and "Separator" is "/" in FIG. 9, the user "Hong Kil Dong" has "01012345678", "Hong Kil Dong" If I have saved my information as "Dongguk University in Jung-gu, Seoul, Jung-gu", the string of the part that constitutes the user information in the QR code is "01012345678 / Hong Gil-dong / Dongguk University in Jung-

10 is a flowchart illustrating an algorithm for converting a list of goods to be paid into a string. This process is a process of converting a list of items to be paid stored in a user smartphone into a character string to be included in the QR code. To convert a string, you need the barcode of each product and the number of products. The detailed information of the product including the barcode attribute is not displayed on the screen when the user scans the barcode and outputs the product information, but is included in the application. And the number refers to the number of each product that the user wants to have, which is also stored in the application as a result of the user's modification of the number. The algorithm shown in FIG. 10 uses the converted string in the 'user personal information-string conversion' algorithm of FIG. 9 described above.

In the product information to be paid, the bar code has an abbreviation of 8 digits and a standard of 13 digits. Therefore, when converting a barcode to a string, you need a character that can distinguish whether the barcode is abbreviated or standard. Prefix the barcode with the barcode, add the barcode, and add the number and delimiter. This process is repeated until all the items in the list are found. The entire information is converted to a single string, all at the end of this algorithm.

The entire process of converting the above-described 'user shopping method information', 'user personal information', and 'goods information to be paid' into a character string will be described as an example. For example, we chose that the user chose to be a member and wanted a shipping service, and did not want mobile payments. If the delimiters indicating selection and non-selection are 'Y' and 'N', respectively, FIG. 11 illustrates user shopping method information stored in the user terminal.

The user who selects the shopping method inputs the user's personal information as needed. Assuming that the user's personal information input by the user is '01012345678', 'Hong Gil Dong', and 'Dongguk University', respectively, in mobile phone number, name and address, FIG. 12 illustrates user personal information stored in the user terminal.

After the user selects a product to be paid, the user scans the barcode of the product with the user terminal and inquires the product information on the shopping mall database. The inquiry result is sent back to the user terminal and stored. This information is the product information to be paid, and various product information is accumulated to make a list of items to be paid. If the user scans 'cookie 1', 'cigarette 1', and 'tablet PC 1', FIG. 13 illustrates a list of goods to be stored in the user terminal.

The information to be contained in the QR code is determined based on the information stored in the user terminal. If it is assumed that '0' and '1' are used for the 8 digits abbreviated type and the 13 digits common type in order to distinguish the number of digits of the barcode from the list of commodities to be paid, The information included in the QR code generated through the present invention is illustrated.

If the information to be included in the QR code is determined, the entire information is converted into a single string by an algorithm that converts the information to a string. Now, if the user information and product information to be included in the QR code are converted into a string, the result is as shown in "YNY / 01012345678 / Hong Gil-dong / Dongguk University / 11111123456891/000001234/133333333333331 /".

Now, the character string containing the encryption information, the user information, and the barcode and the number information of the goods is finally generated by the QR code. At this time, the QR code is generated using the QR code generator, and only one QR code is displayed on the screen in the user application. The QR code recognizes and authenticates the POS terminal, confirms the shopping information of the user and the goods to be settled, and provides identification of the member of the shopping mall, membership, and whether or not to benefit.

FIG. 15 is a flowchart showing a method for processing an arrangement of offline shopping according to an embodiment of the present invention from the viewpoint of a POS terminal, and includes a configuration corresponding to the above-described method for processing an arrangement of offline shopping using the user terminal of FIG. Therefore, redundant explanations are outlined here.

In step S210, the POS terminal scans the QR code displayed on the user terminal. To scan a QR code through a POS terminal, a module capable of scanning a QR code is required. Therefore, a QR code scanner device or related application capable of scanning a QR code must be installed in the POS terminal. If the QR code generated by the user is scanned, the information contained in the QR code can be obtained through the QR code parsing algorithm.

Here, the QR code is generated by combining the OTP value with a random number sequence, dividing the OTP value according to a specific rule, and distributing the divided OTP value to the random number sequence to generate encryption information. The QR code is stored in advance User information, and product information obtained through the user terminal. More specifically, the encryption information may include at least one of an operation expression for the user terminal to divide the OTP value in units of digits, to extract a prime number corresponding to each separated digits, An interval between the OTP values separated by digits, and distributing OTP values separated by the digits in the random number sequence according to the designated interval.

The user information may include at least one of whether or not a payment is made through the user terminal or a delivery request including the member information so that a request for payment through the user terminal or a delivery request is sent to the person in charge of the POS terminal . That is, the POS terminal receives product information for at least one or more goods to be purchased by the user and user information for goods payment at the same time using one QR code displayed on the screen of the user terminal without scanning individual goods do.

In step S220, the POS terminal parses the QR code scanned in step S210 to separate the encryption information, and extracts the OTP value from the extracted encryption information using the specific rule. For this purpose, it is preferable that the encryption information is composed of a fixed length from the starting point of the QR code. That is, the POS terminal can easily extract fixed-length encryption information from the scanned QR code.

Now, the function for extracting the OTP value distributed in the encryption information uses the OTP dispersion formula used for distributing the OTP to the random number sequence. The first digit of the numeric string received through the QR code is the first digit of the OTP, and the next digit is extracted through the function. This is used to reverse the position where the OTP value is inserted to extract each digit of the OTP value.

In step S230, the extracted OTP value is verified through the OTP authentication server. In this process, authentication is performed by checking whether the extracted OTP value matches the OTP value generated by the current OTP authentication server.

In step S240, if the OTP value is verified, the POS terminal extracts user information and product information in the QR code and proceeds with product settlement. That is, assuming that the OTP value is verified, the POS terminal extracts the product information in the QR code and displays it on the screen of the POS terminal, and the POS terminal transmits the user information in the QR code To settle the goods displayed on the screen. If the verification of the OTP value fails, the POS terminal will display an error message and stop the payment process.

After separating the encryption information from the QR code, the remaining two pieces of information are user information and product information, respectively. Hereinafter, the process of parsing and processing each information will be described.

16 is a diagram illustrating an algorithm for parsing user shopping method information. The first character of the part excluding the encryption information in the string which is read by scanning the QR code is a delimiter indicating whether the user is a member. The second character is a character that distinguishes whether the user is mobile or not. The third character is a delimiter that indicates whether the user desires a delivery service. All of this information is stored in the POS system and is applied to user's membership processing, mobile payment, and delivery processing in payment and delivery later. Since the user has already decided on the shopping method and handed it over to the POS terminal, the user can process payment and delivery according to the desired shopping method without any additional question of the employee.

17 is a diagram illustrating an algorithm for parsing user personal information. User shopping method The remaining string after the parsing of the information contains mobile phone number, name and address, which are personal information of the user, and each part is divided into delimiters. The first data of the string read by scanning the QR code means the mobile phone number. If the user information is not written and this data does not have a value, the mobile phone number item in the user information of the POS specifies that there is no value. If there is a value, enter the string up to the first delimiter into the cell phone number item in POS user information. If you have processed your mobile number, go back to the first separator to process the name. As with cell phone numbers, if no value is specified, the user information specifies that the name entry has no value. If there is a value, store the string from the first delimiter to the second delimiter in the name. After processing the name entry, go back to the second separator. The third string is an address, and if there is no value, it specifies that there is no value in the address entry of POS user information. If there is a value, specify the string from the second delimiter to the third delimiter as the address. After processing the address string, delete the part that has been read so far including the third delimiter from the string that scanned the QR code.

18 is a diagram illustrating an algorithm for parsing a list of goods to be paid. The process of 'parsing the product list information to be paid out from the QR code' of FIG. 18 is a process for parsing the user information and parsing the product list information to be set in the remaining character string. The information parsed in this algorithm is the number of the barcode of the product to be paid and the number of the desired purchase number. However, the bar code number is preceded by the separator character that separates the 8-digit abbreviation and the 13-digit general number, and determines the length of the reading. For example, if the delimiter before the barcode number is a letter representing the abbreviation, it reads 8 digits and stores it as a barcode number.

First, it is determined whether the remaining character string exists, and if there is a character string to be parsed, the first character is read to identify the type of the bar code. If the barcode is abbreviated, it reads 8 digits after the delimiter, stores it. If the barcode is standard, it reads and stores 13 digits after the delimiter, and then stores the string in the number of digits before the delimiter. Remove the information and delimiter read from the QR code string after storage. This process repeats until all the elimination is done and there is no more string to read in the QR code. At the end of this algorithm, all the information contained in the string of QR code is parsed.

19 is a flowchart illustrating an algorithm for verifying information parsed from a QR code. This process parses the user information about the membership, the payment method, the hope of delivery, and the information of the goods to be paid from the character string generated from the QR code through the QR code parsing algorithm, queries the database of the mart and applies the contents of the event And finally outputting it to the screen of the POS terminal.

Referring to FIG. 19, the user is discriminated whether he or she is a member by inquiring user information in the database according to the value of the membership-related variables obtained by parsing from the QR code. If the member is a member, it inquires the user information in the database and applies not only the common event contents such as "1 + 1", "Buy one get one" but also the event contents for the members. In the case of non-members, only the common event content is applied without querying the user information in the database. The event application process for the goods to be paid is repeated until there is no product information to be paid, and then some user information and all goods information to be paid are displayed on the screen of the POS terminal. 20 illustrates a screen of a POS terminal outputting end user information and product information to be paid.
