DETAILED DESCRIPTION

An object of at least one embodiment is to provide, in order to solve the problems described above, a server and a program capable of preventing concentration of customers in a store.

According to at least one embodiment, a server includes: a storing unit (storage) configured to store store-visit dates and times in past of a customer; an analyzing unit (at least one processor) configured to analyze a tendency of the store-visit dates and times in the past of the customer stored in the storing unit; a determining unit (at least one processor) configured to determine a next store-visit scheduled day of the customer based on the analyzed tendency; and a transmitting unit (transmitter) configured to transmit the determined store-visit scheduled day to a portable terminal carried by the customer.

At least one embodiment is explained below with reference to the drawings.

FIG. 1 is a diagram illustrating a system 10 in at least one embodiment . As illustrated in FIG. 1, the system 10 includes one or a plurality of POS (Point of Sales) terminals 1 set in a store S and a server 5. The POS terminal 1 and the server 5 are connected by a communication line L such as a LAN (Local Area Network). The POS terminal 1 in at least one embodiment may be either a normal POS terminal operated by a store clerk or a self-service type POS terminal with which a customer performs sales registration operation and settlement operation for commodities by himself or herself. In at least one embodiment, the POS terminal 1 of the type operated by the store clerk is used.

The system 10 includes an access point 3 connected to the communication line L. A plurality of access points 3 are set in the store S and near an entrance E and connected to a portable terminal 7 carried by a customer via wireless communication. The portable terminal 7 performs communication with the POS terminal 1 and the server 5 via the access point 3.

First, the server 5 is explained. The server 5 is a store server configured by a computer and set in, for example, aback office of the store S. The server 5 manages sales information of commodities purchased in the store S. The server 5 manages, for each of customers, dates and times when the customer visited the store S and analyzes, for each of the customers, a tendency of periods (the dates and times) when the customer visited the store S. The server 5 determines the next store-visit scheduled day of the customer based on analyzed data. The store-visit scheduled day may be, for example, information specifying a day when the customer visits the store S (a day of a month), maybe information specifying a range of days when the customer visits the store S (from a day to another day of a month), or may be information specifying a date and a time period when the customer visits the store S (a time period from an hour to another hour of a day of a month).

The server 5 determines whether store-visit scheduled days of many other customers overlap the determined date and time (or date or time period) by comparing the number of customers with an upper limit value of customers who can visit the store S at a time at the same date and time or the same time period (within a predetermined period) and, if the number of customers exceeds the upper limit value, changes the determined store-visit scheduled day to another date and time. For example, the server 5 changes the store-visit scheduled day to the same date and time of the next week. Alternatively, the server 5 changes the store-visit scheduled day to the same time period of another day. In this way, the server 5 disperses the number of customers visiting the store S and adjusts customers to not be concentrated within the predetermined period.

The server 5 analyzes a tendency of purchased commodities of each of the customers based on a purchase history of commodities purchased by the customer and extracts, for each of the customers, a commodity often purchased by the customer. The server 5 sets the extracted commodity as a bargain sale commodity for the customer and generates flier information for the customer including information concerning the bargain sale commodity ((that is, privilege information) the information concerning the bargain sale commodity includes, in addition to information concerning a commodity, information concerning a bargain sale price discounted from a normal price of the commodity). The server 5 includes information concerning the determined store-visit scheduled day in the flier information. The server 5 includes, in the flier information, bargain sale information such that, if the customer visits the store S in a time period of an hour to another hour on a day of a month, the normal price is discounted to the price printed on a flier if the customer purchases the bargain sale commodity printed on the flier.

The portable terminal 7 is described. The portable terminal 7 is a device mounted with a microcomputer such as a smartphone, a cellular phone, or a PDA (Personal Digital Assistant). In at least one embodiment, a smartphone is explained as an example of the portable terminal 7.

The portable terminal 7 includes a camera 84 (see FIG. 8). The portable terminal 7 starts an installed application to perform the following operation. That is, the portable terminal 7 reads, with the camera 84, a code symbol provided near the entrance E of the store S. The portable terminal 7 analyzes the read code symbol and transmits store entry time of the portable terminal 7 (that is, a customer carrying the portable terminal 7) to the server 5 together with a customer code for specifying the customer stored in the portable terminal 7 and a store code for specifying the store S included in the read code symbol. The server 5 stores the store entry time received from the portable terminal 7 in association with the received customer code and the received store code.

The portable terminal 7 captures an image of a commodity or an image a symbol such as a barcode or a two-dimensional code attached to the commodity with the camera 84 and acquires and stores a commodity code for specifying the commodity.

The portable terminal 7 displays a privilege code 830 (see FIG. 12B) obtained by converting the flier information received from the server 5, the information concerning the store-visit scheduled day included in the flier information, and the information concerning the bargain sale commodity into a code symbol.

The portable terminal 7 transmits the stored commodity code to the POS terminal 1.

The POS terminal 1 is set in a payment section in the store S. The POS terminal 1 receives information concerning a commodity to be purchased (in at least one embodiment, a commodity code for specifying the commodity) from the portable terminal 7 and performs sales data processing and settlement processing.

The sales data processing means processing for displaying, based on the received commodity code, commodity information such as a commodity name and a price of the commodity and storing the commodity information in a commodity information unit 131 (see FIG. 7). The settlement processing means processing for performing settlement for the commodity based on the commodity information subjected to the sales data processing and displaying a total amount and a change amount relating to the transaction. If the settlement processing is performed for the commodity subjected to the sales data processing, the POS terminal 1 transmits the commodity information and settlement information of the commodity to the server 5 together with the customer code and the store code.

A store entry code 826 (see FIG. 10B) is posted near the entrance E of the store S. The store entry code 826 is a code symbol in which the store code for specifying the store S is recorded. The portable terminal 7 images the store entry code 826 with the camera 84 provided in the portable terminal 7 to acquire the store code.

In the system 10 having such a configuration, the server 5 determines, for each of customers, the next store-visit scheduled day of the customer, extracts a bargain sale commodity for the customer from a purchase history of the customer, and generates flier information for the customer including a recommended commodity that the store S desires to sell. The server 5 transmits the generated flier information to the portable terminal 7 of the customer.

If visiting the store S, a customer images, with the camera 84, the store entry code 826 posted near the entrance E and, then, enters the store S from the entrance E. The portable terminal 7 sets, with the installed application, as a store entry date and time of the customer, time when the store entry code 826 is imaged and transmits the store entry date and time and the acquired store code to the server 5.

Subsequently, if putting a commodity to be purchased in a cart or a basket in the store S, the customer images, with the camera 84 of the portable terminal 7, a code symbol attached to the commodity and acquires and stores a commodity code of the commodity. The customer performs operation for imaging code symbols for all commodities to be purchased.

If ending the shopping in the store S, the customer preforms an operation for displaying the privilege code 830 generated based on the received flier information and transmitting the imaged commodity code of the commodity to the POS terminal 1.

A store clerk operating the POS terminal 1 reads, using a symbol reading unit 23 (see FIG. 7), the privilege code 830 displayed on the portable terminal 7 presented by the customer. The POS terminal 1 determines, based on the commodity code received from the portable terminal 7 and the information concerning the store-visit scheduled day and the information concerning the bargain sale commodity included in the read privilege code 830, whether the customer visits the store S on the store-visit scheduled day and the bargain sale commodity is included in the received commodity code. If the customer visits the store S on the store-visit scheduled day and the bargain sale commodity is included in the received commodity code, the POS terminal 1 executes sales data processing on the bargain sale commodity at the bargain sale price.

If determining that the privilege code display button 823 is operated (Yes in Act 52), the control unit 700 determines whether privilege code information of the privilege code 830 is stored in the privilege-code storing unit 733 (Act 53) . If determining that privilege code information of the privilege code 830 is stored in the privilege-code storing unit 733 (Yes in Act 53), the control unit 700 displays the privilege code 830 on the display unit 81 (Act 54). FIG. 12B is a diagram illustrating a state in which the privilege code 830 is displayed on the display unit 81. In FIG. 12B, a message 829 such as “Please read the privilege code” is displayed. The store clerk at the POS terminal 1 views the display and performs operation for operating the symbol reading unit 23 and reading the privilege code 830 displayed on the display unit 81.

Subsequently, the control unit 700 determines whether the transmission button 832 is operated (Act 56). If determining that the transmission button 832 is operated (Yes in Act 56), the control unit 700 transmits the commodity code stored in the commodity data unit 731 to the POS terminal 1 (Act 57). At the same time, the control unit 700 transmits, to the POS terminal 1, a date and time when the commodity code is transmitted (a reception date and time) (Act 57). The commodity code may be transmitted to the POS terminal 1 via the access point 3 or may be directly transmitted to the POS terminal 1 using a publicly-known short-range wireless communication technique or the like. The control unit 700 returns to Act 11.

If determining in Act 51 that the end button 831 is not operated (No in Act 51), the control unit 700 returns to Act 11. If determining in Act 56 that the transmission button 832 is not operated (No in Act 56), the control unit 700 returns to Act 52. If determining in Act 53 that privilege code information of the privilege code 830 is not stored in the privilege-code storing unit 733 (No in Act 53), since the privilege code 830 is not stored in the privilege-code storing unit 733, the control unit 700 displays, on the display unit 81, a message indicating that a privilege cannot be received (Act 55) . The control unit 700 returns to Act 52. In this case, the operator operates the transmission button 832 without operating the privilege code display button 823. In Act 52, if determining that the privilege code display button 823 is not operated (No in Act 52) , the control unit 700 performs the determination in Act 56.

A functional configuration of the server 5 is explained below. FIG. 13 is a functional block diagram illustrating the functional configuration of the server 5. The control unit 500 functions as an analyzing unit 501, a determining unit 502, an extracting unit 503, a flier generating unit 504, and a transmitting unit 505 according to a control program stored in the ROM 52 or the memory unit 54 and loaded in the RAM 53.

The analyzing unit 501 analyzes a tendency of store-visit periods (store-visit dates and times) in the past of a customer stored in the customer master 543, which is a storing unit. Specifically, the analyzing unit 501 analyzes, based on store-visit dates and times of the customer stored in the store-entry date and time section 54332 and the payment date and time section 54333, a tendency of dates and times when the customer visits the store S.

The determining unit 502 determines the next store-visit scheduled day of the customer based on the analyzed tendency of the dates and times. Specifically, the determining unit 502 determines a store-visit scheduled day as follows. The determining unit 502 determines a store-visit scheduled day based on information concerning store-visit dates and times in the past of the customer. More specifically, the determining unit 502 determines the next store-visit scheduled day of the customer based on a tendency analyzed by the analyzing unit 501 based on information concerning store entry date and time of the customer stored in the store-entry date and time section 54332 to correspond to a customer having a customer code stored in the customer code section 5431 and information concerning a payment date and time of the customer stored in the payment date and time section 54333. For example, if a customer “AAA” often visits the store S around 13:00 on Sunday every week, the determining unit 502 determines the next store-visit scheduled day of the customer “AAA” to include 13:00 (for example, 12:00 to 15:00) on Sunday next week.

If the determined store-visit scheduled day already overlaps store-visit scheduled days of many other customers and the number of customers exceeds a store-visit upper limit number(in the time period) in a predetermined period, the determining unit 502 determines, for example, the same date and time of the next week. For example, the determining unit 502 determines another time period close to the time period of the same day. If the number of customers at the date and time determined again exceeds the store-visit upper limit number, the determining unit 502 determines another date and time again.

The extracting unit 503 extracts a bargain sale commodity for the customer based on a purchase history. Specifically, the extracting unit 503 extracts, based on a purchase history of the customer stored in the purchase history section 54334, at least one commodity often purchased by the customer in the past as the bargain sale commodity.

The flier generating unit 504 generates flier information including information concerning the extracted bargain sale commodity and the store-visit scheduled day. In at least one embodiment, the flier generating unit 504 generates flier information including, in addition to information concerning the next store-visit scheduled day determined by the determining unit 502 and information concerning the bargain sale commodity extracted by the extracting unit 503, information concerning a recommended commodity recommended by the store S on the store-visit scheduled day and bargain sale information.

The transmitting unit 505 transmits the determined store-visit scheduled day to the portable terminal 7 carried by the customer. In the embodiment, the transmitting unit 505 transmits the flier information generated by the flier generating unit 504 including the determined store-visit scheduled day, the information concerning the bargain sale commodity for the customer, the information concerning the recommended commodity recommended by the store S, and the bargain sale information to an address of the portable terminal 7 stored in the customer information section 5432.

Subsequently, control of the server 5 is explained. FIGS. and 15 are flowcharts illustrating a flow of control processing for the server 5. As illustrated in FIG. 14, the control unit 500 of the server 5 determines whether a customer code, a store code, and store entry time are received from the portable terminal 7 (Act 61). If determining that a customer code, a store code, and store entry time are received from the portable terminal 7 (Yes in Act 61), the control unit 500 stores the received store code and the received store entry time in the customer master 543 in association with the received customer code (Act 62). Specifically, the control unit 500 stores the store entry time in the store-entry date and time section 54332 corresponding to the customer code and the store code (Act 62). The control unit 500 returns to Act 61.

If determining that a customer code, a store code, and store entry time are not received from the portable terminal 7 (No in Act 61), the control unit 500 determines whether a customer code, commodity information, and a reception date and time (details are explained below) are received from the POS terminal 1 (Act 71). If determining that a customer code, commodity information, and a reception date and time are received from the POS terminal 1 (Yes in Act 71), the control unit 500 additionally stores the received commodity information in the sales data unit 531 (Act 72) . The control unit 500 additionally stores the commodity information in the customer master 543 (Act 73). That is, the control unit 500 additionally stores, to correspond to the received customer code, the received commodity information in the purchase history section 54334 corresponding to the received store code (Act 73). The control unit 500 stores the received reception date and time in the payment date and time section 54333 as a payment date and time (Act 74). The control unit 500 returns to Act 61.

If determining that a customer code and commodity information are not received from the POS terminal 1 (No in Act 71), the control unit 500 determines whether predetermined time decided in advance comes (Act 81) . The predetermined time decided in advance is desirably outside business hours of the store S and is, for example, midnight. If determining that the predetermined time comes (Yes in Act 81), the control unit 500 generates flier information (Act 82).

FIG. 15 is a flowchart of the processing for generating flier information in Act 82. As illustrated in FIG. 15, the analyzing unit 501 analyzes, based on all store entry date and time information of a customer stored in the store-entry date and time section 54332 and all payment date and time information of the customer stored in the payment date and time section 54333, a tendency of store-visit periods of the customer (Act 821). Subsequently, the determining unit 502 determines the next store-visit scheduled day of the customer based on the tendency of the store-visit periods of the customer analyzed by the analyzing unit 501 (Act 822).

Subsequently, the control unit 500 determines whether the determined store-visit scheduled day overlaps store-visit scheduled days of many other customers and the number of customers reaches the set upper limit number (Act 823). If it is determined that the number of customers reaches the set upper limit number (Yes in Act 823), the determining unit 502 determines the other next store-visit scheduled day about the customer (Act 824). The control unit 500 returns to Act 823 and determines again whether the number of customers reaches the upper limit number. If it is determined that the number of customers does not reach the set upper limit number (No in Act 823), the extracting unit 503 extracts a bargain sale commodity for the customer based on a purchase history.

Subsequently, the control unit 500 extracts a commodity recommended to be sold by the store S on the determined store-visit scheduled day (Act 826). Subsequently, the flier generating unit 504 generates flier information including information concerning the store-visit scheduled day determined in Act 822 or Act 824, information concerning the bargain sale commodity extracted in Act 825, information concerning the recommended commodity extracted in Act 826, and bargain sale information (Act 827).

Referring back to FIG. 14, subsequently, the transmitting unit 505 transmits the flier information generated in Act 827 to an address of the portable terminal 7 stored in the customer information section 5432 (Act 83) . The control unit 500 returns to Act 61.

As explained above, in the server 5 in the embodiment, the customer master 543, which is the storing unit, stores store-visit dates and times (store entry dates and times and payment dates and times) and commodity purchase histories of customers. The control unit 500 analyzes tendencies of store-visit periods of the customers from the store-visit dates and times and determines the next store-visit scheduled days, extracts bargain sale commodities of the customers from the purchase histories, extracts recommended commodities of the store S, generates flier information for the customers based on these kinds of information, and transmits the flier information to the portable terminal 7. Therefore, it is possible to disperse the next store-visit dates and times of the customers. By providing information concerning the bargain sale commodities and information concerning the recommended commodities to the customers who visit the store S on the store-visit scheduled days, it is possible to motivate the customers to visit the store S on the store-visit scheduled days.

Control of the POS terminal 1 is explained below. FIG. 16 is a flowchart illustrating a flow of control processing for the POS terminal 1. As illustrated in FIG. 16, the control unit 100 of the POS terminal 1 determines whether the symbol reading unit 23 images the privilege code 830 (Act 91). If determining that the symbol reading unit 23 images the privilege code 830 (Yes in Act 91) , the control unit 100 stores information of the imaged privilege code 830 in the privilege information unit 132 (Act 92). The control unit 100 returns to Act 91.

If determining that the privilege code 830 is not imaged (No in Act 91), the control unit 100 determines whether a commodity code is received from the portable terminal 7 (Act 101). If determining that a commodity code is received (Yes in Act 101), the control unit 100 executes sales data processing for storing, in the commodity information unit 131, the received commodity code and commodity information acquired from the commodity master 142 based on the commodity code (Act 102). The control unit 100 stores reception time received simultaneously with the commodity code in the commodity information unit 131 (Act 103). The control unit 100 returns to Act 91.

If determining that a commodity code is not received from the portable terminal 7 (No in Act 101), the control unit 100 determines whether the settlement button 221 is operated (Act 111). If determining that the settlement button 221 is operated (Yes in Act 111), the control unit 100 determines whether commodity information is stored in the commodity information unit 131 (Act 112). If determining that commodity information is stored in the commodity information unit 131 (Yes in Act 112), the control unit 100 determines whether the reception time stored in the commodity information unit 131 is included in a store-visit scheduled day (Act 113).

If determining that the reception time stored in the commodity information unit 131 is included in the store-visit scheduled day (Yes in Act 113) , the control unit 100 determines whether the information of the privilege code 830 is stored in the privilege information unit 132 (Act 114). If determining that the information of the privilege code 830 is stored in the privilege information unit 132 (Yes in Act 114), the control unit 100 determines whether a bargain sale commodity included in the privilege code 830 is included in commodities indicated by commodity codes stored in the commodity information unit 131. If determining that the bargain sale commodity is included in the commodities indicated by the commodity codes, the control unit 100 sets a bargain sale price for the commodity (Act 115). The control unit 100 executes settlement processing on the commodities indicated by the commodity codes stored in the commodity information unit 131 including the bargain sale commodity (Act 116). The control unit 100 transmits the commodity codes and commodity information of the commodities subjected to the settlement processing and the reception time stored in the commodity information unit 131 to the server 5 (Act 117). The control unit 100 returns to Act 91.

If determining in Act 111 that the settlement button 221 is not operated (No in Act 111), the control unit 100 returns to Act 91 . If determining in Act 112 that commodity information is not stored in the commodity information unit 131 (No in Act 112), the control unit 100 executes error processing (Act 118). The control unit 100 returns to Act 91. If the reception time stored in the commodity information unit 131 is a date and time not included in the store-visit scheduled day in Act 113 (No in Act 113), the control unit 100 executes the processing in Act 116 without executing the determination in Act 114 and the processing in Act 115. That is, since the date and time when the customer visits the store S is a date and time other than the store-visit scheduled day included in the flier information, the customer cannot obtain a privilege that the bargain sale commodity can be purchased at the bargain sale price. If determining in Act 114 that the information of the privilege code 830 is not stored in the privilege information unit 132 (No in Act 114) , the control unit 100 executes the processing in Act 116 without performing the processing in Act 115. That is, if the privilege code 830 is not stored, the customer cannot obtain the privilege that the bargain sale commodity can be purchased at the bargain sale price. In this case, it is likely that the store clerk does not image the privilege code 830. Therefore, the control unit 100 may notify a message for urging imaging of the privilege code 830.

As explained above, in the embodiment, the server 5 in the embodiment includes the customer master 543 that stores store-visit dates and times in the past of a customer, the analyzing unit 501 that analyzes a tendency of the store-visit dates and times in the past of the customer stored in the customer master 543, the determining unit 502 that determines the next store-visit scheduled day of the customer to the store S based on the analyzed tendency, and the transmitting unit 505 that transmits the determined store-visit scheduled day to the portable terminal 7 carried by the customer.

The server 5 in the embodiment determines and transmits the next store-visit scheduled days for each of the customers. Accordingly, it is possible to prevent concentration of the customers in the store S.

In the embodiment, if the number of customers exceeds the upper limit value of customers visiting the store S, other store-visit scheduled days are determined to prevent the number of customers from exceeding the upper limit value of the number of customers visiting the store S. Accordingly, it is possible to prevent concentration of the customers in the store S.

The server 5 in the embodiment transmits, as privilege information, information concerning bargain sale commodities relating to customers who visit the store S on the store-visit scheduled days. Accordingly, the customers are motivated to visit the store S on the store-visit scheduled days. Therefore, it is possible to prevent concentration of the customers in the store S.

The embodiments are explained above. However, the embodiments are presented as examples and are not intended to limit the scope of the invention. These embodiments can be implemented in other various forms. Various omissions, substitutions, changes, combinations can be made without departing from the spirit of the invention. These embodiments and modifications of the embodiments are included in the scope and the gist of the invention and included in the inventions described in claims and the scope of equivalents of the inventions.

For example, in the embodiment, the information concerning the bargain sale commodity is included in the flier information and transmitted. However, not only this, but the flier information may not include the information concerning the bargain sale commodity.

In the embodiment, the flier information is transmitted to the customer. However, not only this, but at least information concerning the next store-visit scheduled day only has to be transmitted to the customer. The other information is not essential.

In the embodiment, the information concerning the extracted bargain sale commodity is transmitted to the customer as the privilege information. However, not only this, but, for example, if a special store-visit point is granted to the customer who visits the store S on the store-visit scheduled day, information concerning the store-visit point transmitted to the portable terminal 7 is the privilege information. For example, if a present or the like is given to the customer who visits the store on the store-visit scheduled day, information concerning the present or the like transmitted to the portable terminal 7 is the privilege information.

In the embodiment, the control unit 100 of the POS terminal 1 reads the privilege code displayed by the portable terminal 7 and grasps the bargain sale commodity for the customer. However, not only this, but, for example, the server 5 may grasp, for each of customers, flier information to the customers and, if the POS terminal 1 inputs a customer code for specifying a customer by, for example, reading the customer code, the POS terminal 1 may acquire, from the server 5, flier information of the customer specified by the input customer code and grasp a bargain sale commodity for the customer. Alternatively, the POS terminal 1 may acquire information concerning a bargain sale commodity relating to the customer from the server 5. For example, if a plurality of kinds of flier information are present for one customer, the plurality of kinds of flier information are stored in the server 5. Simply by inputting one customer code, the POS terminal 1 can grasp information concerning a bargain sale commodity for the customer based on the plurality of kinds of flier information received from the server 5. Alternatively, the POS terminal 1 can acquire information concerning a bargain sale commodity relating to the customer from the plurality of kinds of flier information stored by the server 5.

The program executed by the server 5 in the embodiment is provided by being recorded in a computer-readable recording medium such as a CD-ROM, a flexible disk (FD), a CD-R, or a DVD (Digital Versatile Disc) as a file of an installable format or an executable format.
