Description

FIELD OF TECHNOLOGY

[0001] The presented technical solution relates, in general, to the field of computer technology, and in particular to a method and system for determining whether a terminal belongs to a shopping center (SC).

BACKGROUND OF THE INVENTION

[0002] From the prior art solutions are known that allow you to determine the location of unknown terminals.

[0003] The closest solution to the claimed solution is a method and apparatus for determining information about the location of the transaction device, disclosed in patent RU 2680198 C2. In the known solution, the transaction data uploaded by the terminal is obtained when an electronic payment for the transaction is made by the terminal displaying the unique digital object identifier, and the transaction execution device scanning the displayed unique digital object identifier and transmitting payment information associated with the unique digital object identifier to the server to complete the transaction, the transaction data being associated with the transaction, after which the transaction device identifier and the transaction address information also included in the transaction data are determined, the transaction device identifier containing the identifier of the transaction device itself, and the transaction address information contains the location of the terminal at the same time as the transaction, and determines and stores the location information of the terminal as the location of the implementation device transactions corresponding to the identifier of the transaction device.

[0004] The disadvantage of the known solution is the inability to determine the belonging of the terminal to the shopping center based on the analysis of paired transaction data with terminals, the belonging of which is determined.

ESSENCE OF THE TECHNICAL SOLUTION

[0005] The technical problem or technical challenge posed in this technical solution is the creation of a new effective, simple and reliable solution for automated determination of the terminal's belonging to the shopping center.

[0006] The technical result achieved when solving the above technical problem or technical problem is to provide the possibility of determining the belonging of the terminal to the shopping center based on the data of paired transactions with terminals, the belonging of which is determined. [0007] The specified technical result is achieved due to the implementation of a computer-implemented method for determining whether a terminal belongs to a shopping center (SC), performed using at least one processor and comprising the steps of:

• from the database with the addresses of the locations of the shopping centers, the shopping center is selected, in which it is necessary to determine the ownership of the terminals;

• select terminals from the database whose ownership is determined and corresponds to the selected shopping center;

• calculate for each selected terminal the allowable time range of a paired transaction, with a terminal whose ownership is not defined, based on the parameters of the selected shopping center;

• identify paired transactions for each selected terminal, with a terminal whose ownership is not defined, committed within the allowable time range;

• filter paired transactions by MCC codes to exclude transactions that are not relevant to the categories of expenses and services of the corresponding shopping centers;

• exclude paired transactions made without a sign of the physical presence of the buyer in the shopping center at the time of its completion;

• assign each paired transaction a weight based on the amount of time elapsed between transactions;

• summing the weights of paired transactions for each terminal, the ownership of which is not defined;

• set a threshold value for each terminal whose ownership is not defined;

• determine whether the terminal belongs to the shopping center based on the achievement of the specified threshold value by the terminal.

[0008] In one of the particular examples of the implementation of the method, the TC parameter is at least the area of the TC

[0009] In another particular embodiment of the method, the more time has passed between paired transactions, the less weight is assigned to the paired transaction.

[0010] In another particular embodiment of the method, the less time elapsed between paired transactions, the more weight is assigned to the paired transaction.

[0011] In another preferred embodiment of the claimed solution, a system for determining whether a terminal belongs to a shopping center is presented, comprising:

• at least one processor;

• at least one memory coupled to the processor that contains machine-readable instructions that, when executed by at least one processor, perform the above method.

BRIEF DESCRIPTION OF THE DRAWINGS

[0012] The features and advantages of the present technical solution will become apparent from the following detailed description of the technical solution and the accompanying drawings, in which:

[0013] In FIG. 1 is a diagram of the data processing method.

[0014] In FIG. 2 is an example of a general view of a computing device.

IMPLEMENTATION OF THE TECHNICAL SOLUTION

[0015] The concepts and terms necessary for understanding this technical solution will be described below.

[0016] In this technical solution, the system means, including a computer system, a computer (electronic computer), CNC (numerical control), PLC (programmable logic controller), computerized control systems and any other devices capable of performing a given , a well-defined sequence of operations (actions, instructions).

[0017] A command processing device is an electronic unit, a computing device, or an integrated circuit (microprocessor) that executes machine instructions (programs).

[0018] The command processor reads and executes machine instructions (programs) from one or more data storage devices. The role of a storage device can be, but not limited to, hard disk drives (HDD), flash memory, ROM (read only memory), solid state drives (SSD), optical drives.

[0019] A program is a sequence of instructions intended to be executed by a computer control device or command processing device.

[0020] The terminal is the end part of a system that provides communication between the system and the external environment. In systems for accepting payments, a payment terminal is used for user interaction with the system, and the operation is performed by the card user. Also, the terminal can be a POS-terminal - a device for paying for goods (services) using payment cards, and the operation is performed by the cashier.

[0021] As shown in FIG. 1, the claimed method for determining whether a terminal belongs to a shopping center (SC) (100) consists of several interconnected steps performed by at least one processor.

[0022] At step (101), a shopping center is selected from the database with location addresses of the shopping center, in which it is necessary to determine the ownership of the terminals.

[0023] The database contains information with the addresses of the shopping center, information about the parameters of the shopping center, for example, the area of the shopping center, the categories of goods and services provided by the shopping center, the passability of the shopping center, the location relative to the city center in which the shopping center is located, the distance from the metro (if it is in the city ), the population of the city where the shopping center is located, etc.

[0024] At step (102), terminals are selected from the database, the affiliation of which is determined and corresponds to the selected shopping center.

[0025] The acquiring database contains information about terminals whose ownership is determined in relation to the shopping center in which they are installed.

[0026] At step (103), for each selected terminal, the allowable time range of a paired transaction is calculated, with a terminal whose affiliation is not determined, based on the parameters of the selected TP.

[0027] The time range depends on the parameters of the shopping center, such as: the area of the shopping center, the passability of the shopping center, the location relative to the city center in which the shopping center is located, the distance from the metro (if there is one in the city), the population of the city in which the shopping center is located, etc. .d.

[0028] For a shopping center with an area of up to 30 thousand square meters, the upper threshold for the time of a paired transaction is set to 20 minutes. For shopping centers with an area of 30,000 to 60,000 square meters, the upper threshold for a paired transaction is 25 minutes. For shopping centers with an area of 60,000 to 90,000 square meters, the upper threshold for a paired transaction is 30 minutes. For shopping centers with an area of more than 90,000 square meters, the upper threshold for a paired transaction is 40 minutes.

[0029] These ratios of area to the threshold of time were identified as a result of experiments in different shopping centers with different parameters and are taken as the basis for determining the range of paired transactions.

[0030] At step (104), for each selected terminal, paired transactions are identified, with a terminal whose ownership is not determined, committed within a valid time range.

[0031] At this stage, all paired transactions of terminals whose ownership is determined with terminals whose membership is not determined in a given time range are selected.

[0032] If the time threshold is exceeded by a paired transaction, then it is considered that this terminal, whose ownership is not determined, is outside the selected shopping center.

[0033] If the time threshold is not exceeded by a paired transaction, then such a transaction is selected for further analysis.

[0034] The transaction data may include a user identifier (ID), terminal ID, transaction time, MCC code, and other information.

[0035] At step (105), paired transactions are filtered by MCC codes to exclude transactions that are not relevant to the categories of expenses and services of the corresponding shopping centers.

[0036] MCC code (Eng. Merchant Category Code - “merchant category code”) is a four-digit number that classifies the type of activity of a merchant and service point during a bank card payment transaction. A company is assigned an MCC code when it starts accepting cards. As a rule, the code is assigned automatically by the bank providing the acquiring service (acceptance of bank cards for payment as a means of payment for goods or services), when installing and configuring the POS terminal based on a questionnaire on the nature of trade and service activities.

[0037] At this stage, all paired transactions are filtered out that do not correspond to the categories of spending in the selected shopping center (categories of transport, auto services, housing and communal services, hotels, etc.).

[0038] At step (106), paired transactions are excluded, made without a sign of the physical presence of the buyer in the shopping center at the time of its completion. This type of transactions is tracked by a sign, which is indicated in the transaction properties. There is a pos data code field in the transaction properties, which contains a set of characters. One of the symbols indicates the physical presence of the client at the terminal when making a transaction.

[0039] At step (107), each paired transaction is assigned a weight based on the amount of time elapsed between transactions.

[0040] The function has the form y=1/t.

[0041] The more time passed between paired transactions, the less weight is assigned to the paired transaction.

[0042] The less time has passed between paired transactions, the more weight is assigned to the paired transaction.

[0043] At step (108), the weights of paired transactions for each terminal, the ownership of which is not determined, are summed.

[0044] At this stage, the total weight of all paired transactions for terminals whose ownership is not determined that have passed the previous selection stages is calculated.

[0045] In step (109), a threshold value is set for each terminal whose membership is not determined.

[0046] At this stage, a threshold value of the sum of the transaction weights for terminals whose membership is not determined is set. The threshold value of the weight is determined for each shopping center and depends on the parameters of the shopping center.

[0047] At step (110), the terminal's belonging to the shopping center is determined based on the achievement of the predetermined threshold value by the terminal.

[0048] All terminals that have reached or exceeded the threshold are considered to belong to the selected shopping center.

[0049] Thus, it is possible to determine the belonging of the terminal to the shopping center based on the analysis of data of paired transactions with terminals, the belonging of which is determined.

[0050] Additionally, terminals with the same merchant name are combined into brands. The entire sample by terminals is graded by weight from the minimum to the maximum. Terminals with a weight below the average and not passing the threshold are distributed by % deviation from the average.

[0051] Next, 10% of terminals with a weight below the average value is checked for the presence of a terminal of the same brand with a weight above the average value. If matches are found, then such terminals are considered related to the shopping center.

[0056] Various types of I/O interfaces (204) are used to organize the operation of device components (200) and organize the operation of external connected devices. The choice of appropriate interfaces depends on the particular design of the computing device, which can be, but not limited to: PCI, AGP, PS/2, IrDa, FireWire, LPT, COM, SATA, IDE, Lightning, USB (2.0, 3.0, 3.1, micro, mini, type C), TRS/Audio jack (2 5, 3.5, 6.35), HDMI, DVI, VGA, Display Port, RJ45, RS232, etc.

[0057] To ensure user interaction with the device (200), various means (205) of I/O information are used, for example, a keyboard, a display (monitor), a touch display, a touchpad, a joystick, a mouse, a light pen, a stylus, a touch panel, trackball, speakers, microphone, augmented reality tools, optical sensors, tablet, light indicators, projector, camera, biometric identification tools (retina scanner, fingerprint scanner, voice recognition module), etc.
