Abstract

<P>PROBLEM TO BE SOLVED: To provide a cash register system which is capable of deriving a correctly discounted price as a transaction price even after derivation of a price for members. <P>SOLUTION: In a POS system 100, a normal price for members resulting from discounting a total commodity price by a normal discount rate is derived (step S9) when member information is inputted. However, a special price for members resulting from discounting the total commodity price by a special discount rate is derived in stead of the normal price for members when a special discount indication is given (Yes in step S10) even after derivation of the normal price for members. Therefore, the price correctly discounted by the special discount rate is derived as the transaction price. <P>COPYRIGHT: (C)2008,JPO&INPIT

Description

  The present invention relates to a technique for deriving a transaction price used for settlement of a sales transaction in a store.

  In sales transactions of retail stores such as supermarkets and convenience stores, a cash register system called a POS system is used. In the cash register system, the prices of the products that the customer desires to purchase for each sales transaction are totaled and derived as a total product price.

  Normally, this total product price is used as the transaction price for settlement of sales transactions. However, in some stores, in order to maintain and expand good fixed customers, there is a system that preferentially treats the transaction price to customers who become members. May be adopted. Specifically, for a store member, the member price obtained by uniformly discounting the total product price at a predetermined discount rate is used as the transaction price. In a cash register system of a store adopting this system, when member information is input by reading a member card or the like, this member price is automatically derived as a transaction price.

  As prior art documents disclosing techniques related to the present invention, there are the following documents.

Japanese Patent No. 2891442

  By the way, in the store which performs member discounts as described above, a system for further preferential treatment to some specific members of members has been proposed. For example, a direct mail is mailed to a particularly good member among the members, and a special discount rate (for example, 5%) larger than the normal discount rate (for example, 5%) is given to the member who brought this direct mail. For example, it has been proposed that the price discounted by 10%) be the transaction price.

  However, in the conventional cash register system, only a process of discounting the transaction price derived at that time was possible. Therefore, once the member price is derived as the transaction price, the member price can only be discounted, and a price obtained by correctly discounting the total product price at the special discount rate cannot be derived.

  For example, if a regular member receives a discount of 5% of the normal discount rate and a member who presents direct mail receives a discount of 10% of the special discount rate, the total product price is 10,000 yen. Assume a certain transaction. In this sales transaction, when member information is input to the cash register system, a member price of 9,500 yen obtained by discounting the total product price at a normal discount rate of 5% is derived as the transaction price. After that, only a discount on this member price (9,500 yen) can be made, so if a further 5% discount is given to the member who brought the direct mail, a transaction price of 9,025 yen will be derived. . This transaction price of 9,025 yen is different from 9,000 yen, which is a price obtained by correctly discounting the total product price at a special discount rate.

  The present invention has been made in view of the above problems, and an object of the present invention is to provide a technique capable of deriving a correctly discounted price as a transaction price even after deriving a member price.

  In order to solve the above-mentioned problem, the invention of claim 1 is a cash register system used for a sales transaction in a store, and means for deriving a total product price that is a total price of products related to one sales transaction; Means for inputting member information indicating that a customer who conducts one sales transaction is a member of the store, and when the member information is input, the total product price is discounted at a predetermined first discount rate. A means for deriving one member price as a transaction price used for the settlement of the one sales transaction, and a discount instruction for discounting at a second discount rate different from the first discount rate after deriving the first member price from the operator Means for receiving, and means for deriving, as the new transaction price, a second member price obtained by discounting the total product price at the second discount rate when the discount instruction is given.

  The invention of claim 2 is a method of deriving a transaction price used for settlement of a sales transaction in a store, the step of deriving a total product price that is the sum of the prices of products related to one sales transaction, A step of inputting member information indicating that a customer who conducts one sales transaction is a member of the store; and a step of discounting the total product price at a predetermined first discount rate when the member information is input. A step of deriving one member price as the transaction price, a step of receiving a discount instruction from an operator for discounting at a second discount rate different from the first discount rate after deriving the first member price, and the discount instruction And a step of deriving, as the new transaction price, a second member price obtained by discounting the total product price at the second discount rate.

  According to the first and second aspects of the invention, even after the first member price is derived, the second member price is derived by discounting the total product price at the second discount rate, so that the correct discount is made. Price can be derived as the transaction price.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

<1. Configuration>
FIG. 1 is a diagram showing a configuration of a POS system 100 that is a cash register system according to an embodiment of the present invention. The POS system 100 is employed in a store such as a supermarket or a convenience store, and includes a POS server 1 and a plurality of POS terminals 2. The POS server 1 and the POS terminal 2 are each connected to the LAN 3 and can communicate with each other.

  The POS server 1 controls the entire POS system 100 in an integrated manner, and is usually arranged in a management office or the like different from the store sales area. On the other hand, the POS terminal 2 is arranged in the sales area of the store, and is actually operated by the sales staff of the store in the case of merchandise sales transactions. Specifically, the POS terminal 2 is used for settlement processing for deriving a transaction price used for settlement of a sales transaction, settlement of the sales transaction, and the like.

  FIG. 2 is a functional block diagram showing the configuration of the POS server 1. The POS server 1 has the same hardware configuration as a general computer. That is, the POS server 1 has a configuration in which a CPU 11 that performs arithmetic processing, a ROM 12 that stores basic programs, a RAM 13 that is a work area for arithmetic processing, and a hard disk 14 that stores various data are connected to the bus line 10. ing. The POS server 1 further includes a display 15 that displays various information, an input unit 16 such as a keyboard and a mouse, and a communication unit 17 that communicates via the LAN 3, which are connected to the bus line 10. The

  A processing program is stored in the hard disk 14, and various functions as the POS server 1 are realized by the CPU 11 performing arithmetic processing according to the processing program. The hard disk 14 further stores data necessary for the checkout process such as the product master 41 and the customer master 42.

  The product master 41 is data in a table format indicating various information about each product handled at the store. The product master 41 includes a plurality of records. In each record, information such as “product name” and “price” is associated with “product code” which is an identification code for identifying a product. .

  On the other hand, the customer master 42 is data in the form of a table indicating various types of information about customers who have become members of the store. The customer master 42 includes a plurality of records. In each record, information such as “name” and “contact” is associated with “member code” which is an identification code for identifying a member. . Information about the customer in the customer master 42 is registered when the customer becomes a member of the store.

  In the store of the present embodiment, a membership card is given to a customer registered as a member in the customer master 42. The member card is a magnetic stripe card, and member information according to a predetermined format including the “member code” of the member is recorded on the magnetic stripe. The membership information recorded on the membership card indicates that the customer who owns the membership card is a legitimate member of the store. Specifically, if the member information conforms to a predetermined format and the “member code” included in the member information is registered in the customer master 42, the member information is valid and the customer It can be judged that it is a legitimate member.

  FIG. 3 is a diagram showing the configuration of the POS terminal 2 in functional blocks. The POS terminal 2 is attached to a product, a control unit 21 that controls the entire apparatus, two displays 22 and 23 that display various types of information, an input unit 24 that has various buttons that accept operator operations and inputs, and the like. A barcode reader 25 that reads a barcode, a card reader 26 that reads a magnetic stripe of a membership card, a print issuing unit 27 that prints and issues a receipt, and a communication unit 28 that communicates via the LAN 3. These are respectively connected to the bus line 20. The input unit 24 includes various buttons such as a subtotal key for instructing a subtotal process in the settlement process and a numeric keypad.

  The control unit 21 includes a CPU 201 that performs various arithmetic processes, a ROM 202 that stores a control program, a RAM 203 that is a work area for arithmetic processes, a battery-backed SRAM 204 that is a nonvolatile memory that stores various data, And a timer 205 having a time measuring function. The control function of each part of the apparatus and the data processing function for the settlement process are realized by the CPU 201 performing arithmetic processing according to the control program in the ROM 202.

  Of the two displays 22 and 23, one display 22 is a sales-side display 22 that displays information to be displayed on the side of a sales staff who is an operator, and the other display 23 is on the customer side. It is the customer side display 23 which displays the information which should be shown.

  The screen of the sales side display 22 is composed of a dot matrix type liquid crystal, and can display various information such as characters, figures and images in color. On the other hand, the screen of the customer-side display 23 is composed of a relatively simple VFD (fluorescent display tube), and can only display a single line of character strings in two lines. The orientation of the screen of the customer-side display 23 is adjusted so that the customer can easily see in the checkout process.

<2. Member discounts>
In the store according to the present embodiment, a system for preferentially treating members in terms of price over customers other than members is adopted. In the case of a customer other than a member, the total product price obtained by adding up the prices of products desired to be purchased is used as the transaction price used for the settlement of the sales transaction. On the other hand, in the case of a member, in principle, the member price obtained by discounting the total product price at a predetermined discount rate (for example, 5%) is used as the transaction price.

  In addition, in this store, direct mails are mailed to specific members that are part of the members, for example, members with a large purchase amount or members with a near birthday. And, a system that gives further preferential treatment to members who bring this direct mail is adopted. Specifically, for members who bring direct mail, the member price obtained by discounting the total product price at a discount rate (for example, 10%) larger than the normal discount rate (for example, 5%) of the member described above is dealt with. The price.

  Hereinafter, the normal discount rate of members is referred to as “normal discount rate”, and the member price obtained by discounting the total product price at the normal discount rate is referred to as “normal member price”. Further, a discount rate applied only to a specific member who brings direct mail is called “special discount rate”, and a member price obtained by discounting the total product price at the special discount rate is called “special member price”.

<3. Checkout process>
In the POS system 100, such normal discount rate and special discount rate are stored in advance in the SRAM 204 of the POS terminal 2, and the normal member price and special member price are derived in the settlement process. Hereinafter, the settlement process of the POS system 100 will be described.

  FIG. 4 is a diagram showing the flow of the settlement process. The series of processing shown in FIG. 4 is processing mainly performed in the POS terminal 2 for each sales transaction (for each product group that one customer desires to purchase).

  First, if the customer is a member of the store, the customer presents a membership card. When the membership card is presented, the magnetic stripe of the membership card is read by the card reader 26 of the POS terminal 2, and thereby the membership information of the magnetic stripe is input to the POS terminal 2. It is determined whether or not the input member information conforms to a predetermined format, and is transmitted to the POS server 1 to determine whether or not the included “membership code” is registered in the customer master 42. Determined.

  If it is determined by these determinations that valid member information indicating that the customer is a member of the store has been entered (Yes in step S1), this indicates that the customer who performs the sales transaction is a member. A member flag, which is a flag (a variable in the RAM 203 of the POS terminal 2), is turned on (step S2).

  Next, the barcode attached to one product in the product group that the customer desires to purchase is read by the barcode reader 25 of the POS terminal 2, whereby the “product code” of the product is read by the POS terminal 2. (Step S3).

  The acquired “product code” is transmitted from the POS terminal 2 to the POS server 1. In response to this, the POS server 1 searches the product master 41 for a record including the “product code”, and returns the contents of the corresponding record to the POS terminal 2. As a result, product data such as “product name” and “price” of the product is acquired by the POS terminal 2. The acquired product data is stored in the RAM 203. Thereby, the merchandise registration of the merchandise is performed (step S4).

  Subsequently, when the product code related to the next product is acquired (Yes in step S5), the process in step S4 is performed again, and the product is registered in the same manner. Such processing is repeated in the same manner for all products that the customer desires to purchase, thereby registering products for all products. That is, product data such as “product name” and “price” related to all products is stored in the RAM 203.

  When all the products are registered in this manner, the sales staff as an operator presses the subtotal key included in the input unit 24. When the subtotal key is pressed (Yes in step S6), the total product price, which is the sum of the “price” for all acquired products, is derived by the CPU 201 and stored in the RAM 203 (step S7).

  When the total product price is derived, it is next determined whether or not the member flag is ON. If the member flag is OFF, that is, if the customer is not a member of the store (No in step S8), the total product price is displayed on the sales side display 22 and the customer side display 23 as the transaction price that is the amount that the customer should pay as it is. (Step S12).

  On the other hand, if the member flag is ON, that is, the customer is a member of the store (Yes in step S8), the normal member price obtained by discounting the total product price at a normal discount rate (for example, 5%) is the CPU 201 as the transaction price. Is derived by More specifically, the total product price is multiplied by a normal discount rate (for example, 5%), and the result of rounding such as rounding is derived as a discount amount. Then, the result of subtracting the discount amount from the total product price is derived as the normal member price. The derived normal member price is displayed as a transaction price on the sales side display 22 and the customer side display 23 (step S9).

  When the customer is a store member, the normal member price is automatically derived as the transaction price by pressing the subtotal key in this way. However, if the direct mail is presented by the customer before the settlement, the special discount key included in the input unit 24 is pressed by the sales staff as the operator after the normal member price is derived. When the special discount key is pressed, the CPU 201 of the POS terminal 2 receives a special discount instruction for discounting the total product price at the special discount rate.

  When a special discount instruction is given (Yes in step S10), the process using the normal member price as the transaction price is canceled. Then, a special member price obtained by discounting the total product price at a special discount rate (for example, 10%) is derived by the CPU 201 as a new transaction price. More specifically, the total product price stored in the RAM 203 is multiplied by a special discount rate (for example, 10%), and the result of rounding such as rounding off is derived as a discount amount. Then, the result of subtracting the discount amount from the total product price is derived as the special member price. The derived special member price is displayed as a transaction price on the sales side display 22 and the customer side display 23 (step S11). Here, it is assumed that the member information obtained from the member card is not canceled only by canceling only the transaction price calculated with the normal member price. As a result, the transaction price at the special member price is added to the cumulative purchase of the member.

  As described above, when a transaction price corresponding to a customer is derived and displayed, a settlement process is performed based on the transaction price. That is, an amount of cash for settlement delivered from the customer is input as a deposit amount via the input unit 24, and a result obtained by subtracting the transaction price from the deposit amount is derived as a change amount, and the change amount is displayed. 22 and 23. Thereby, the settlement process of this sales transaction is completed (step S13). Next, the contents of the sales transaction are transmitted to the POS server 1 and recorded on the hard disk 14 as sales performance data, and a receipt indicating the content of the sales transaction is issued by the print issuing unit 27 (step S14). As a result, a series of payment processing ends.

  Thus, in the POS system 100, when member information is input, a normal member price obtained by discounting the total product price by a normal discount rate is derived. However, even after the derivation of the normal member price, when the special discount instruction is given, the special member price obtained by discounting the total product price at the special discount rate is derived instead of the normal member price. For this reason, the price at which the correct discount rate is obtained can be derived as the transaction price.

  In the representative form, the special discount rate is constant, but the operator may arbitrarily set the special discount rate by operating the input unit 24. In this case, the special discount instruction is accepted by the POS terminal 2 by pressing a predetermined key after setting the special discount rate. Further, by printing a barcode specifying a special discount rate on a direct mail or the like and reading the barcode with the barcode reader 25, the special discount rate is set and the special discount instruction is accepted. It may be.
