Description

  The present invention relates to an environmental protection contribution management system that manages daily purchase behavior for environmental protection of a customer and gives some incentive based on the contents.

  At the 3rd Conference of the Parties to the United Nations Framework Convention on Climate Change held in 1997, with the aim of reducing greenhouse gas emissions (such as carbon dioxide and methane) that cause global warming into the atmosphere, The Kyoto Protocol, which imposes greenhouse gas emission reduction targets on developed countries, was adopted and entered into force in Japan in 2005.

  In the Kyoto Protocol, the gas reduction target for each country is set, and emissions trading between countries is allowed to achieve the target.

  Along with this, a domestic emission trading system that enables trading of emissions between companies in Japan has been tried since 2008.

  However, the domestic emissions trading system described above is mainly targeted at the industrial sector, and efforts are being made at the local government and local levels to achieve reduction targets in the household sector.

  For example, in retail stores such as supermarkets and convenience stores, polyethylene shopping bags (hereinafter also referred to as “shopping bags”), which have been distributed free of charge in the past, are charged, or customers have their own shopping bags (hereinafter “ Efforts such as the My Bag campaign that does not use shopping bags by bringing “My Bag”.

  These are beginning to be widely accepted in conjunction with incentive measures such as increasing consumers' awareness of environmental protection and giving points or discounting a certain amount from the purchase price when they decline to accept plastic bags.

  In such a situation, Patent Document 1 discloses a technique regarding a support system for reducing greenhouse gas emissions by reducing the amount of petroleum-derived products used in the household sector.

  In Patent Document 1, when there is another alternative means such as using a my bag without using a shopping bag, when the customer selects the alternative means, it can be used for the customer at the next product purchase. It describes a system that gives incentives of points to encourage the selection of alternatives and reduce greenhouse gas emissions.

  In addition, in Patent Document 2, when a customer purchases food such as lunch boxes or cup noodles, if he / she declines the attachment of disposable chopsticks, etc., information that will lead to resource protection is printed along with the discount amount. A purchase receipt that strongly impresses the customer with the consciousness and a purchase receipt issuing device that improves operability by providing a dedicated input key for the discount are disclosed.

  Furthermore, in Patent Document 3, when a customer intends to purchase a product, it is used when a customer brings an alternative container and uses it instead of a container such as a plastic bottle or a foam tray that is usually sold. Carbon dioxide emission reduction calculation system and carbon dioxide to reduce the amount of carbon dioxide emission according to the amount of carbon dioxide generated when disposing of normal containers that did not exist to the customer as discounts or points A technology related to an emission reduction trading system is disclosed.

  Before explaining the present invention in detail, the meaning of terms used in the explanation will be explained.

  First, “attachments” are provided to customers free of charge or at a low cost for the convenience of the customer who purchased the product. For example, shopping bags, disposable chopsticks, soy sauce in a sachet Say things like wasabi and wasabi.

  In addition, the “Eco Mark” means that a company has signed a contract with the Japan Environmental Association for products that are recognized as being useful for environmental conservation with little impact on the environment throughout the product life cycle from production to disposal. It is a mark to be issued. This Eco Mark was established in 1989.

  “Basic attitude” refers to either environmental protection (does not require shopping bags or disposable chopsticks) or convenience (such as eliminating the need to carry shopping bags and prepare chopsticks at home). In the present invention, it is classified into the following three types.

  That is, the first is “environmental protection priority type”, which prioritizes environmental protection over convenience, the second is “environmental protection non-priority type”, which prioritizes convenience over environmental protection, and The third is a “balance type”, which uses different priorities for environmental protection and convenience depending on the situation.

  These basic posture types are registered in the database in advance as basic posture information for each customer, and as described later, the price of the above-mentioned accessory is determined according to the accumulation of actions taken by the customer in the past, This is used to determine the discount amount of the purchase price according to the selection contents of the purchased product.

  Further, “CO 2” means carbon dioxide, and “CO 2 emission amount” means the amount of carbon dioxide that is considered to be generated when a product is disposed of. The “CO2 reduction amount” means the amount of carbon dioxide generated when the above-mentioned eco-marked product is disposed of, and the amount of carbon oxide generated when the same type of product without the eco-mark is disposed of. Difference in CO2, that is, the amount of carbon dioxide reduced by purchasing eco-marked products, and the amount of carbon dioxide reduced by declining attachments. This is the value obtained by dividing the CO2 reduction amount by the CO2 emission amount.

  Next, the operation of the first embodiment will be described in detail with reference to the flowchart of FIG.

  FIG. 7 is a flowchart showing an outline of operations of the database server 10 and the store terminal 20 when a customer purchases a product.

Each store issues a customer ID to each customer in advance, and performs initial setting of the customer database 110 so that the customer can access. Then, the customer uses the customer terminal 30 to access the customer table 111 in the customer database 110, and in the row corresponding to the customer ID issued to the customer ID column of the customer table 111, the basic attitude and the accessory are required. Customer information such as / unnecessary is registered prior to purchasing a product at a store.
Here, the issue of the customer ID and the initial setting of the customer database 110 may be performed collectively by the headquarters of a chain store such as a supermarket or a convenience store or a specialized affiliate company. Further, the registration of customer information in the customer table 111 may be performed by the headquarters or affiliated company of each store or chain store on behalf of the customer when issuing the customer ID.

  In addition to the issuance of the customer ID, the store also distributes to the customer a membership card or point card printed with a barcode indicating the customer ID, or a magnetic card or IC card recording the customer ID. These are used as means for specifying a customer ID when purchasing a product at each store. Hereinafter, these cards are collectively referred to as a “customer ID card”.

  This customer ID card may be used in cooperation with other credit card companies, electronic money card companies, etc., and the present invention can be used by using the credit cards or electronic money cards of the respective companies.

  Moreover, it is good also as adding the credit function of another company, a point function, etc. to this customer ID card.

  This eliminates the need for the customer to present multiple cards at the time of product purchase (for example, presenting the customer card of the present invention and a credit card of another company that settles the product price), improving customer convenience Can be achieved.

  Furthermore, in the present invention, the customer ID card is not limited to the above cards, and may be any one of a mobile phone, a PDA (Personal Digital Assistant), a smartphone, and the like.

  Referring to FIG. 7, first, when a customer purchases a product, the customer presents a customer ID card to the store clerk, and the store clerk is recorded on the customer ID card in the bar code reader 22 or card reader 23 provided in the store terminal 20. The customer ID is read. Then, the read customer ID is sent from the store terminal 20 to the database server 10 (step S1).

  Upon receiving the customer ID, the database server 10 reads customer information that matches the customer ID from the customer table 111, obtains the past cumulative accessory purchase rate and cumulative CO2 reduction rate, and stores the customer information together with the customer information. The data is sent to the terminal 20 (step S2).

  Here, the past cumulative accessory purchase rate and cumulative CO2 reduction rate are obtained by the following calculation formula using the numerical values in each column of the row corresponding to the customer ID of the customer table 111.

-Cumulative accessory purchase rate = number of accessories purchased / number of visits x 100 (1)
・ Cumulative CO2 reduction rate = CO2 cumulative reduction ÷ CO2 cumulative emissions x 100 (2)
The store terminal 20 displays the customer information received from the database server 10, the past cumulative accessory purchase rate, and the cumulative CO2 reduction rate on the screen of the input / output unit 21 (step S3). The store clerk refers to the information and uses it as a reference for customer service. For example, when the accessory purchase rate is 50% or more, even if the plastic bag column and the disposable chopsticks column of the customer table 111 are “unnecessary”, the customer is confirmed as unnecessary.

  Next, the store clerk causes the barcode reader 22 provided in the store terminal 20 to read the product IDs of one or more products that the customer purchases this time. Then, each read product ID is sent from the store terminal 20 to the database server 10 (step S4).

  Upon receiving each product ID, the database server 10 reads product information that matches each product ID from the product table 131 (step S5), and calculates the total price of the product purchased this time, the CO2 emission amount and the reduction amount of each product. The total, the CO2 reduction rate, and the return amount are obtained, and those values are sent to the store terminal 20 (step S6).

  Here, a method of calculating the CO2 reduction rate and the return amount of the product purchased this time will be described below.

  First, the CO2 reduction rate of the product purchased this time is obtained by the following calculation formula using the values in the CO2 reduction amount column and the emission amount column of the purchased product in the product table 131.

・ Current CO2 reduction rate = total of CO2 reduction amount of all purchased products ÷ total amount of CO2 emission of all purchased products × 100 (3)
Next, the return amount at the time of purchase this time is the total CO2 reduction amount of the products purchased by the customer this time, the unit return amount table 107 in FIG. 10, and the current CO2 reduction rate calculated by the above formula. Based on the environmental load reduction contribution point multiplication factor obtained by applying to the environmental load reduction contribution point multiplication factor table 9 in FIG.

・ Reduction amount at the time of purchase this time = total CO2 reduction amount of all products purchased this time × reduction amount per kilogram of CO2 reduction × environmental load reduction contribution factor multiplication factor (4)
For example, if the basic attitude of the customer is a balance type and the CO2 reduction rate of the product purchased this time is 4.5%, the environmental load reduction contribution point multiplier is 1. 07. And if the total amount of CO2 reduction of the products purchased this time is 0.2 kilograms, the return amount per kilogram is 50 yen (FIG. 10), so the return amount is 0.2 × 50 × 1 0.07 = 10.7 yen.

  The store terminal 20 displays on the screen of the input / output unit 21 the above-mentioned total product price received from the database server 10, the total CO2 emission amount and reduction amount of all purchased products, and the current CO2 reduction rate ( Step S7).

  Subsequently, the database server 10 calculates the required number of accessories and the total value of CO2 emissions from the product table 131 and the accessory table 132.

  Here, the required quantity of the plastic bag of the accessory is not directly related to the present invention, but the size and weight of the product purchased by the customer is compared with the allowable size and allowable weight of the accessory table 132, It is calculated by the following method.

  First, the remainder of the margin size of the compatible plastic bag when the product to be purchased is put in the compatible plastic bag is described later with reference to the allowable size of the compatible plastic bag and the information on the size and margin direction of the purchased product. Calculate according to the method and confirm that it is greater than zero.

  Next, it is confirmed that the volume of the remaining size of the applicable plastic shopping bag is 40% or more of the volume of the allowable size.

  Next, it is confirmed that the total weight of purchased products is equal to or less than the allowable weight of the applicable shopping bag.

  And any one of the width, height, and the remaining dimension in the depth direction of the applicable plastic shopping bag is less than or equal to 0 (zero), or the volume of the remaining plastic bag is less than 40% of the allowable size. If the total weight of the purchased product exceeds the allowable weight of the applicable plastic shopping bag, confirm the plastic bag (ie, add 1 to the required number of the compatible plastic shopping bag) Repeat the above check for the next purchased item.

  Then, the above confirmation is performed for all purchased products, and the necessary quantity of shopping bags is determined.

  Next, a method for calculating the remaining margin size of the above-mentioned compatible shopping bag will be described below.

[When the margin direction column of the purchased product is “A”, that is, when there is a margin in the depth direction when the purchased product is placed in a compatible shopping bag]
The remaining size in the width direction of the compatible plastic bag remains the same as the value obtained by subtracting the width direction dimension of the product from the allowable size in the width direction of the compatible plastic bag.

  The remaining dimension in the height direction of the compatible plastic bag remains the same as the value obtained by subtracting the dimension in the height direction of the product from the allowable dimension in the height direction of the compatible plastic bag.

  The remaining size in the depth direction of the compatible shopping bag is calculated according to the following calculation formula (5).

・ Remaining dimension in the depth direction of the compatible plastic bag after the update = Remaining dimension in the depth direction of the current compatible plastic bag (the initial value is the allowable dimension in the depth direction of the compatible plastic bag) −the dimension in the depth direction of the product. (5)
[When the margin direction column of the purchased product is “B”, that is, when there is a margin in the height direction when the purchased product is placed in a compatible shopping bag]
The remaining size in the width direction of the compatible plastic bag remains the same as the value obtained by subtracting the width direction dimension of the product from the allowable size in the width direction of the compatible plastic bag.

  The remaining size in the height direction of the compatible shopping bag is calculated according to the following calculation formula (6).

・ Remaining size in the height direction of the updated compatible plastic bag = Remaining size in the height direction of the current compatible plastic shopping bag (the initial value is the allowable dimension in the height direction of the compatible plastic bag) −the height of the product Dimensions in the vertical direction (6)
The remaining dimension in the depth direction of the compatible shopping bag remains the same as the value obtained by subtracting the depth dimension of the product from the allowable dimension in the depth direction of the compatible shopping bag.

[When the margin direction column of the purchased product is “C”, that is, when there is a margin in any of the width, height, and depth directions when the purchased product is put in a compatible shopping bag.]
The remaining size in the width direction of the compatible shopping bag is calculated according to the following calculation formula (7).

・ Remaining size in the width direction of the compatible plastic bag after renewal = Remaining size in the width direction of the current compatible plastic bag (the initial value is the allowable size in the width direction of the compatible plastic bag) −the width direction dimension of the product. (7)
The remaining size in the height direction of the suitable shopping bag is calculated according to the above-described calculation formula (6), and the remaining dimension in the depth direction is calculated according to the above-described calculation formula (5).

  Next, the database server 10 uses the values in the accessory charge multiplication rate table 105 in FIG. 8 to calculate the offer price of the accessory to the customer, and the result is the above-mentioned required accessory quantity and CO2 emission. Along with the total amount, it is sent to the store terminal 20 (step S8).

  Here, the calculation method of the price provided to the customer of the accessory will be described below.

  For the price provided to customers of accessories, the cumulative CO2 reduction rate calculated by equation (2) above and the current CO2 reduction rate calculated by equation (3) are applied to the accessory charge multiplier table 105. Calculated according to the following formula based on the attached product charge multiplier.

・ Provided price = cumulative charge rate for attached items x current charge rate for attached items x standard price for attached items (8)
For example, if the basic attitude of the customer is a balance type and the cumulative CO2 reduction rate in the past, which is the calculation result of Equation (2), is 3.7%, the cumulative charge rate of the accessory is 2.5 (table 105). In the CO2 reduction rate column, 3.7% is included in the range, and the value of the intersection of the row of 2.5% or more and less than 4.5% and the cumulative column in the balance type column), and further, the equation (3) When the current CO2 reduction rate, which is the calculation result, is 4.5%, the accessory charge multiplier for this time is 0.9 (4.5% is included in the range in the CO2 reduction rate column of the table 105). % Of the intersection of the line of% or more and less than 6.0% and the current column in the balance type column). When the standard price of the plastic bag is 4 yen, the provided price of the current plastic bag is 2.5 × 0.9 × 4 = 9.0 yen.

  The store terminal 20 displays on the screen of the input / output unit 21 the above-mentioned necessary number of attached items received from the database server 10, the provided price of the attached items, and the total value of the CO2 emission amount.

  Next, the store clerk inputs information indicating whether the present accessory is necessary or not from the input / output unit 21 (step S9). That is, since the content of the customer information received from the database server 10 (information of the corresponding customer ID row in the customer table 111) is already displayed on the screen of the input / output unit 21 as an initial value and presented to the customer. The store clerk proceeds with the process without confirming with the customer whether or not accessories such as shopping bags and disposable chopsticks are necessary. However, if the customer wishes to respond differently from his / her customer information displayed on the screen of the input / output unit 21, for example, the customer who has previously registered customer information that the shopping bag and the disposable chopsticks are unnecessary is owned by the customer. If you forgot your shopping bag and need a shopping bag only for this time, the store clerk modifies the required / unnecessary value of the shopping bag as required and inputs it from the input / output unit 21. .

  Next, the store terminal 20 confirms whether the input accessory is necessary / unnecessary, and if the accessory is not necessary (if branched to “NO” in step S10), it is received from the database server 10 in step S6. The returned amount is displayed on the screen of the input / output unit 21 (step S11).

  Next, the store terminal 20 calculates the payment amount of the customer and displays it on the screen of the input / output unit 21. When an accessory is required (when branching to “YES” in step S10), the total price of the product received from the database server 10 in step S6 and the offer price of the accessory received from the database server 10 in step S8 Is added to the customer's payment amount. If no accessory is required (when branching to “NO” in step S10), the return amount received from the database server 10 in step S6 is subtracted from the total product price to obtain the customer's payment amount.

  That is, when the accessory is not required, the reduction amount calculated according to the CO2 reduction rate of the product purchased this time is discounted from the payment amount. If a point card is used, it may be returned to the customer as points instead of discounting from the current payment amount.

  After the payment amount is presented to the customer on the screen of the input / output unit 21 and the payment is completed, the store terminal 20 stores the customer ID, whether or not the accessory has been purchased, the store number, The cash register number and purchase date and time are sent to the database server 10 (step S12).

  The database server 10 adds these data received from the store terminal 20, the product ID and quantity of the purchased product already received, and the ID and quantity of the attached product to the performance table 121 (step S13). If the attachment is declined, the number of attachments is changed to a negative value and registered to indicate that the attachment has been declined.

  Next, the database server 10 includes a basic attitude column, a plastic bag column, a disposable chopsticks column, a store visit count column, an accessory purchase count column, a cumulative CO2 emission column, and a CO2 reduction column of the customer table 111. Is updated (step S14).

  Here, the detail of the update method of each item of the customer table 111 is shown below.

  The basic attitude column is updated as follows according to the cumulative accessory purchase rate value calculated by equation (1) in step S2 when the value in the store visit count column is a multiple of 5.

  -If the cumulative accessory purchase rate is 0% to 30%, the current value in the basic attitude column is updated to "Environmental protection priority type".

  ・ If the cumulative accessory purchase rate is 31% to 69%, the current value in the basic attitude column is updated to “balanced”.

  -When the cumulative accessory purchase rate is 70% to 100%, the current value in the basic attitude column is updated to "environmental protection non-priority type".

  For the plastic bag field and the disposable chopsticks field, the cumulative accessory purchase rate calculated by the equation (1) in step S2 is equal to or greater than a preset threshold (for example, 50%), and the current field becomes “unnecessary”. If set, it is updated to “Question”.

  For the number of visits to the store, the current value in the relevant field is updated to a value obtained by adding 1 to the current value in the relevant field.

  In the accessory purchase frequency column, when at least one accessory such as a shopping bag or disposable chopsticks is purchased, the current value in the relevant field is updated to a value obtained by adding 1 to the current value in the relevant column.

  For the cumulative CO2 emission amount column and the cumulative CO2 reduction amount column, the relevant column is updated with the result calculated according to the following calculation formula.

・ Updated cumulative CO2 emissions = current cumulative CO2 emissions + total CO2 emissions of all purchased products + total CO2 emissions of all purchased accessories ... (6)
・ Total CO2 reduction amount after renewal = Current cumulative CO2 reduction amount + Total CO2 reduction amount of all purchased products + Total CO2 emission amount of all attachments that have been declined (7)
As described above, according to the present embodiment, there is an effect that both the store side and the customer side can save extra labor and time when shopping.

  The reason is that the customer uses the customer terminal 30 in advance to register the customer information in the customer table 111 of the customer database 110, and the clerk displays the customer information on the store terminal when purchasing the product. This is because the customer can be accommodated.

  In addition, in the present embodiment, there is an effect that the customer can be encouraged to actively select a product with a large amount of CO2 reduction, and the customer's continuous environmental protection awareness can be improved.

  The reason for this is that the customer of the accessory is such that the larger the CO2 reduction rate is, the cheaper it is, based on the total CO2 reduction rate of each product purchased by the customer and the cumulative value of the CO2 reduction rate of products purchased by the customer in the past. The total purchase price of the product is calculated by declining the amount calculated based on the total amount of CO2 emissions and total CO2 reduction of each product purchased by the customer and withdrawing the attachment. This is because the customer can always check the cumulative value of the above-mentioned CO2 emission amount and reduction amount using the customer terminal 30 by using the customer terminal 30.

[Second Embodiment]
Next, a second embodiment of the present invention will be described.

  In the first embodiment, customer information and purchase record information of products purchased by the customer are held in the customer database 110 and the record database 120 included in the database server 10, respectively.

  Therefore, after first reading the customer ID from the customer ID card with the barcode reader 22 or card reader 23 provided in the store terminal 20, the data is sent to the database server 10 to search for customer information, etc. The purchase ends, and finally, the product purchase record is sent to the database server 10 to add / update the purchase record information and customer information. As a result, the store terminal 20 must wait for these processes to be completed. There is.

  In the second embodiment, as will be described later, customer information and purchase record information of a product purchased by a customer are stored in a storage unit of a customer ID card such as an IC card or a magnetic card, whereby the above-mentioned database is stored. The processing of the server 10 is reduced.

  As described above, in the present invention, the customer ID card is not limited to cards, and may be any one of a mobile phone, a PDA (Personal Digital Assistant) and a smartphone.

  Hereinafter, the second embodiment will be described in detail with reference to the drawings.

  In the following description, the description of the present embodiment that overlaps with the components and operations of the first embodiment will be omitted.

  FIG. 11 is a block diagram showing the overall configuration of the second embodiment.

  Referring to FIG. 11, in the second embodiment, the database server 10, the store terminal 20, the input / output unit 21, the barcode reader 22, the customer terminal 30, the customer ID card 50, and the card reader / writer 60 are used. The store terminal 20 and the database server 10 are connected to each other via a communication line 40.

  FIG. 12 shows the configuration of the database server 10 of the second embodiment.

  Referring to FIG. 12, the database server 10 includes an accessory provision price calculation unit 100, a reduction amount calculation unit 101, and a product database 130.

  Note that the accessory provision price calculation unit 100, the reduction amount calculation unit 101, and the product database 130 have the same configuration and operation as those of the first embodiment, and thus detailed description thereof is omitted.

  FIG. 13 shows the configuration of the customer ID card 50.

  Referring to FIG. 13, the customer ID card 50 includes a customer table 111 and a performance table 121. The customer table 111 and the performance table 121 are configured in the same manner as those in the first embodiment, and thus will be described in detail. Is omitted.

  In FIG. 11, the store terminal 20 includes a card reader / writer 60 that can read the customer table 111 and the record table 121 recorded on the customer ID card 50 in addition to the configuration of the first embodiment.

  Note that the function of the card reader 23 provided in the store terminal 20 in the first embodiment is included in the card reader / writer 60, so the card reader 23 is not necessary in the second embodiment. .

  In FIG. 11, the customer terminal 30 only needs to have a card reader / writer 60 that can read the customer table 111 and the performance table 121 recorded in the customer ID card 50, which is necessary in the first embodiment. Internet connection function is not necessary.

  Next, the operation of the second embodiment will be described in detail with reference to the flowchart of FIG.

  FIG. 14 is a flowchart showing an outline of operations of the database server 10 and the store terminal 20 when a customer purchases a product.

  Each store issues a customer ID and a customer ID card 50 in which customer information is registered to each customer in advance.

  Here, the issue of the customer ID and the customer information registration and issue to the customer ID card 50 may be issued and registered at each store simultaneously as described above, or at each store the customer ID and customer ID. Only the card 50 may be issued first, and the customer himself / herself may register his / her customer information in the customer table 111 included in the customer ID card 50 using the customer terminal 30 at a later date.

  Further, the issue of a customer ID and the registration and issue of customer information to the customer ID card 50 may be performed collectively by a chain store headquarters such as a supermarket or a convenience store or a specialized affiliate company.

  In addition, in order for the customer to receive the application of the reduction amount due to the decline of the attachment, which will be described later (that is, purchase product discount), customer information must be registered in the customer ID card 50 prior to purchasing the product at the store. Is required.

  Referring to FIG. 14, first, when a customer purchases a product, the customer presents the customer ID card 50 to the store clerk, and the store clerk records the customer information recorded in the customer ID card 50 on the card reader / writer 60 provided in the store terminal 20. Is read (step S20).

  Next, the store terminal 20 calculates the past cumulative accessory purchase rate and cumulative CO2 reduction rate of the customer and displays them on the screen of the input / output unit 21 together with the read customer information. The information is referred to for customer service (step S21).

  Note that the past cumulative accessory purchase rate and cumulative CO2 reduction rate of the above customer are calculated using the same formulas (1) and (2) as in the first embodiment, using the items in the customer table 111. calculate.

  Next, the store clerk causes the barcode reader 22 provided in the store terminal 20 to read the product IDs of one or more products that the customer purchases this time. Then, each read product ID, the customer information read in step S20, and the past cumulative CO2 reduction rate of the customer calculated in step S21 are sent to the database server 10 (step S22).

  The database server 10 that has received each product ID, customer information, and the cumulative CO2 reduction rate of the customer matches each product ID from the product table 131 and the attachment table 132, as in the first embodiment. The product information to be read and the accessory information of the necessary accessory are read (step S23).

  Next, the database server 10 determines the total price of each product, the total CO2 emission amount and the total CO2 reduction amount of each product, the CO2 reduction rate and reduction amount for this purchase, the quantity of necessary accessories, and Calculate the total amount of CO2 emissions and the price provided to customers of the required accessories.

  Note that the calculation method for each item is the same as that in the first embodiment, and thus the description thereof is omitted.

  Then, the database server 10 sends each of the calculated items to the store terminal 20 (steps S24 and S25).

  Next, the store terminal 20 displays each item received from the database server 10 on the screen of the input / output unit 21 (steps S26 and S27).

  Next, the store clerk advances the processing based on the necessity / unnecessity of the necessary accessories displayed on the screen of the input / output unit 21 (step S28). That is, since the content of the customer information read from the customer ID card 50 has already been displayed on the screen of the input / output unit 21 as an initial value and presented to the customer, the store clerk can provide the customer with an accessory such as a shopping bag or disposable chopsticks. The process proceeds without confirming necessity / unnecessity. However, if the customer desires a response different from the customer information displayed on the input / output unit 21, the store clerk corrects the necessary / unnecessary value of the accessory as desired and inputs it from the input / output unit 21. To do.

  Next, the store terminal 20 confirms whether the input accessory is necessary / unnecessary, and if the accessory is not necessary (if branched to “NO” in step S29), it is received from the database server 10 in step S26. The returned amount is displayed on the screen of the input / output unit 21 (step S30).

  Then, the store terminal 20 calculates the customer's payment amount and displays it on the screen of the input / output unit 21 (step S31). The calculation method of the customer's payment amount is the same as that in the first embodiment, and the description thereof is omitted. Here, when the attached product is not required, the reduction amount calculated according to the CO2 reduction rate of the product purchased this time is discounted from the payment amount, as in the first embodiment.

  After the payment amount is presented to the customer and the payment is completed, the store terminal 20 updates the customer table 111 and the result table 121 included in the customer ID card 50 (steps S32 and S33). Here, since the method of updating the customer table 111 and the performance table 121 is the same as that of the first embodiment, the description thereof is omitted.

  Finally, the store clerk returns the updated customer ID card 50 to the customer.

  As described above, in the second embodiment, there is an effect that it is possible to reduce the time for the customer terminal 20 to wait for the processing of the database server 10 to end.

  The reason is that the customer information and the purchase record information of the product purchased by the customer are stored in the storage means of the customer ID card 50 to search the customer information in the database server 10 and the purchase of the product. This is because the process of adding / updating the record information and the customer information can be eliminated.
