Description

  The present invention relates to a POS terminal, and more particularly to a POS terminal for product settlement at a duty-free shop.

Traditionally, duty-free sales to non-residents such as foreign tourists are the same for non-residents who are non-consumable items such as home appliances, kimonos, clothes, bags, etc. The total daily sales of general merchandise at stores was limited to over 10,000 yen.
However, as a result of the tax exemption system revision in October 2014, sales of consumables such as foods, beverages, chemicals, and cosmetics in one store for the same non-resident in one store Those with amounts exceeding 5,000 yen and in the range of up to 500,000 yen are newly included in the tax exemption.

  Although the tax exemption requirements have become more complex due to the expansion of the scope of goods exempted from such tax exemptions, ECR (Electronic Cash Register) terminals such as cash registers installed in duty free shops, POS terminals (Point of Sales, point-of-sale information management (hereinafter “POS terminal”) remains the same.

  By the way, in general, the purchase of duty-free goods is often performed at a limited time such as waiting time for departure after the departure procedure. Therefore, a customer who intends to purchase a duty-free product needs to purchase a product so that the type of tax-exemptable goods and the range of the tax-exempt amount satisfy the tax-exempt requirement in a short time until leaving the country. In addition, when purchasing a product in two or more times at the same store, it is necessary to tabulate and confirm receipts individually, so there is no room for careful examination and selection of the product.

In relation to such a problem, an invention of a duty-free product purchase reservation system that reserves purchase of a product sold at a duty-free store is disclosed (for example, see Patent Document 1).
In addition, an invention of a duty-free product sales system including a step of accepting a duty-free product purchase reservation by a customer through a telecommunication line is also disclosed (for example, see Patent Document 2).

  However, many of the public wireless LAN services for foreign tourists in Japan are dedicated to the Japanese language, and many of them require membership registration. In addition, many foreign tourists are still unfamiliar with internet reservations abroad.

  In view of such circumstances, it is an object of the present invention to provide a POS terminal that facilitates grasping the remaining amount of a tax-free amount when a customer purchases a tax-free product at a duty-free store.

  The present invention relates to a product information acquisition unit that acquires product information by reading a product code of a product related to settlement, a storage unit that holds a list of tax exempt items and a daily tax exemption limit, and a settlement A printing unit that prints receipt information to be printed on a receipt; and a control unit that controls the product information acquisition unit, the storage unit, and the printing unit. Provided is a POS terminal characterized in that, based on a list of target articles and the tax exemption limit, a total amount of tax exempt articles purchased by a customer and a balance of the tax exemption amount are calculated and printed on the printing unit. It is.

<Configuration of POS terminal 1>
The configuration of the POS terminal 1 according to the present invention will be described below with reference to FIGS.
FIG. 1 is a block diagram showing a schematic configuration of a POS terminal 1 of the present invention. FIG. 2 is an explanatory diagram showing an example of the passport number management table 131 shown in FIG. FIG. 3 is an explanatory diagram showing an example of the sales table 132 shown in FIG.

  As shown in FIG. 1, the POS terminal 1 of the present invention includes a control unit 10, an operation unit 11, a scanner 12, a storage unit 13, a display unit 14, and a printing unit 15.

  In the first embodiment, the “product information acquisition unit” of the present invention is realized by the scanner 12.

<Configuration of POS terminal 1>
Hereinafter, each component shown in FIG. 1 will be described.

  The POS terminal 1 is a device that performs payment of goods such as an ECR (Electronic Cash Register) terminal such as a cash register.

  The control unit 10 is a part that controls the operation of each component of the POS terminal 1, and is mainly realized by a microcomputer including a CPU, a ROM, a RAM, an I / O controller, a timer, and the like.

The operation unit 11 is an interface for performing operations such as product settlement and setting by the POS terminal 1. The user operates the operation unit 11 to execute an instruction for the POS terminal 1. The operation unit 11 includes an array of a plurality of keys.
In the case of the POS terminal 1 having a touch panel, an instruction to the POS terminal 1 may be executed by designating a position or coordinates on the screen of the display unit 14 with a fingertip or a touch pen.

  The scanner 12 is a part for inputting product information by optically reading a two-dimensional bar code such as a one-dimensional bar code or a QR code (registered trademark) attached to a product or a wrapping paper of the product.

The storage unit 13 is an element or storage medium that stores information necessary for realizing various functions of the POS terminal 1, a control program, a passport number management table 131, a sales table 132, and the like. As the storage unit 13, for example, a semiconductor element such as a RAM or a ROM, a storage medium such as a hard disk, a flash storage unit, or an SSD is used.
Note that the program and data may be held in different devices such that the data holding area is a hard disk drive and the program holding area is a flash storage unit.

The display unit 14 is a part that displays various types of information to the user (cash register operator) or customer of the POS terminal 1.
The display unit 14 displays a product settlement screen. The display unit 14 includes, for example, a CRT display, a liquid crystal display, an EL display, or an LED lamp, and a display device such as a monitor or a line display for displaying electronic data such as a processing state by an operating system or application software. It is.

  The printing unit 15 is a part that prints receipts or receipts at the time of product checkout, and confirmation data for various settings of the POS terminal 1. The printing unit 15 is not limited to a built-in type, and may be an external type.

As shown in FIG. 2, the passport number management table 131 has two items: a passport number and a purchase management number N.
The passport number is a number unique to a non-resident (passport number, etc.). Further, it is not necessarily the same as the actual passport number as long as it is a number, symbol or combination thereof that can identify a non-resident.
The purchase management number N indicates the number of past sales used using the same passport number.

In the example of FIG. 2, the purchase management number N of the customer A with the passport number “1234567” is “1”, so it is understood that the customer purchased the product only once.
On the other hand, since the purchase management number N of the customer B with the passport number “7654321” is “2”, it is understood that the customer has purchased the product twice.

As shown in FIG. 3, the sales table 132 has four items: sales number, sales date, sales time, and passport number.
In the example of FIG. 3, the sales date and sales time of the sales number “S0001” are “20XX / 1/1” and “12:30:12”, respectively, and the passport number is “7654321”. This indicates that the customer B having the passport number “7654541” purchased the product around 12:30 on January 1, 20XX.
Further, the sales date and sales time of the sales number “S0002” are “20XX / 1/1” and “13:23:15”, respectively, and the passport number is “1234567”. This indicates that the customer A having the passport number “1234567” purchased the product around 13:23 on January 1, 20XX.
The sales date and sales time of the sales number “S0003” are “20XX / 1/1” and “14:00:02”, respectively, and the passport number is “7654321”. This indicates that the customer B having the passport number “7654541” purchased the product around 14:00 on January 1, 20XX.

<Specific example of processing of POS terminal 1 when non-resident purchases tax-exempt goods>
Next, a specific example of processing of the POS terminal 1 will be described with reference to FIG.
FIG. 4 is a flowchart showing processing of the POS terminal 1 shown in FIG.

In step S1 of FIG. 4, the control unit 10 determines whether the customer is a non-resident (step S1).
Specifically, the cashier operator of the POS terminal 1 confirms whether or not the customer is a non-resident based on whether or not a passport has been presented. That is, when the customer presents the passport, the cashier operator operates the operation unit 11 and inputs the passport number to the POS terminal 1. On the other hand, if the customer does not present a passport, the cashier operator performs normal sales processing assuming that the customer is not a non-resident.

When the customer is a non-resident and the passport number is input (when the determination in step S1 is Yes), the control unit 10 accepts the input of the passport number in step S2 (step S2).
On the other hand, when the customer is not a non-resident and the passport number has not been input (when the determination in step S1 is No), the control unit 10 performs normal sales processing in step S3 (step S3). Thereafter, in step S12, the payment details are printed on the receipt (step S12).

  Next, when the passport number is input in step S2, the control unit 10 records the input passport number in the sales table 132 of the storage unit 13 in step S4 (step S4).

  Next, the control part 10 performs a sales process in step S5 (step S5).

Next, in step S6, the control unit 10 determines whether or not there is a purchase record of the tax exempt goods on the purchase date with the input passport number (step S6).
When there is a purchase record of the tax exempt object (when the determination in step S6 is Yes), the control unit 10 calculates the remaining tax exemption amount in step S7 (step S7). Then, the control part 10 performs the process of step S9.
Details of the tax exemption amount calculation in step S7 will be described later in the description of FIG.

On the other hand, when there is no purchase record of the tax exempt goods (when the determination in step S6 is No), the control unit 10 performs an initialization process and a tax exemption frame balance calculation in step S8 (step S8). Then, the control part 10 performs the process of step S9.
The details of the initialization process and the tax exemption amount calculation in step S8 will be described later in the description of FIG.

Next, in step S9, the control unit 10 determines whether or not the current tax exemption frame remaining amount is larger than an amount obtained by subtracting the tax exemption lower limit from the tax exemption upper limit (step S9).
The determination in step S9 is a determination as to whether or not the lower limit of the total daily sales amount is satisfied among the tax exemption requirements.

Here, the “last tax exemption amount remaining amount” indicates the amount of money remaining at the time immediately before the current sales within the daily exemption limit.
Further, “current duty-free quota amount” indicates the amount of money left after the current sales within the daily duty-free quota.
Note that the tax exemption frame is input in advance to the storage unit 13 of the POS terminal 1 and is changed as needed when a change occurs.

  For example, in the case of consumables such as foods, beverages, medicines, and cosmetics, the lower limit of the daily tax exemption frame at the same store for the same non-resident is 51 yen and the upper limit is 50 It will be 10,000 yen.

  In the determination in step S9, when the current tax exemption amount is larger than the amount obtained by subtracting the tax exemption lower limit from the tax exemption upper limit (when the determination in step S9 is Yes), the control unit 10 in step S10, the printing unit 15 To control that the tax exemption requirement has not been reached and the remaining amount until the requirement is achieved (current tax exemption frame remaining amount-tax exemption upper limit amount-tax exemption lower limit amount) is printed on the receipt (step S10). Then, the control part 10 performs the process of step S11 (step S11).

  On the other hand, if the current amount of the tax exemption limit is equal to or less than the amount obtained by subtracting the tax exemption lower limit from the tax exemption upper limit (when the determination in step S9 is No), the control unit 10 controls the printing unit 15 to Then, the current duty-free frame balance and the purchase management number N are printed on the receipt (step S9). Thereafter, the control unit 10 ends the processing of the POS terminal 1.

<Specific Example of Initialization Processing of POS Terminal 1 and Processing for Calculation of Remaining Duty Free Space when Purchase Record of Duty Free Product does not exist>
Next, a specific example of the initialization processing of the POS terminal 1 and the processing for calculating the tax-exempt amount when there is no purchase record of the tax-exempt goods will be described with reference to FIG.
FIG. 5 is a flowchart showing an initialization process and a process for calculating a tax-exempt amount when there is no purchase record of the tax-exempt goods of the POS terminal 1 shown in FIG. The process in FIG. 5 corresponds to the process in step S8 in FIG.

  In step S21 of FIG. 5, the control unit 10 determines whether or not the input passport number exists in the passport number management table 131 of the storage unit 13 (step S21).

When the input passport number exists in the passport number management table 131 (when the determination in step S21 is Yes), the control unit 10 uses the passport number as a key in the passport number management table 131 in step S22. The purchase management number N of the record is initialized (step S22).
Specifically, “1” is input to the purchase management number N in the passport number management table 131 shown in FIG.
Then, the control part 10 performs determination of step S24 (step S24).

  On the other hand, when the input passport number does not exist in the passport number management table 131 (when the determination in step S21 is No), the control unit 10 uses the passport number management table 131 in step S23 to determine the passport number. Is added (step S23). Then, the process of step S22 is performed (step S22).

  Finally, in step S24, the control unit 10 determines whether or not the total amount (A) of the tax-exempted items purchased this time is equal to or greater than the tax-exempt upper limit (step S24). The determination in step S24 is a determination of whether or not the upper limit of the total daily sales amount is satisfied among the tax exemption requirements.

  When the total amount (A) of the tax-exempted goods purchased this time is equal to or greater than the tax-exempt upper limit (when the determination in step S24 is Yes), the control unit 10 sets “0 yen” as the current tax-free frame balance in step S25. An amount is input (step S25). Thereafter, the control unit 10 ends the process.

  On the other hand, when the total amount (A) of the tax exempted goods purchased this time is less than the tax exemption upper limit (when the determination in step S24 is No), the control unit 10 exempts the “previous tax exemption frame balance” in step S26. The upper limit amount is input, and an amount obtained by subtracting the total amount (A) of the tax exempted goods purchased this time from the tax exemption upper limit amount is input to “current tax exemption frame remaining amount” (step S26).

<Specific example of the processing for calculating the remaining amount of the tax exemption amount of the POS terminal 1 when the purchase record of the tax exempt item exists>
Next, based on FIG. 6, a specific example of the initialization process of the POS terminal 1 and the tax exemption amount calculation process when there is a purchase record of the tax exempt goods will be described.
FIG. 6 is a flowchart showing the processing for calculating the remaining tax-free frame when there is a purchase record of the tax-free product of the POS terminal 1 shown in FIG. The process in FIG. 6 corresponds to the process in step S7 in FIG.

  In step S31 of FIG. 6, the control unit 10 increases the purchase management number N in the passport number management table 131 by 1 (step S31).

  Next, in step S32, the control unit 10 calculates the total amount (B) of the tax exempt items purchased by the customer with the passport number on the day (step S32).

  Next, in step S33, the control unit 10 determines whether or not the total amount (B) of the tax exempt items purchased by the customer with the passport number on the day is equal to or greater than the tax exemption upper limit amount (step S33).

  When the total amount (B) of the tax exempt items purchased by the customer of the passport number on the day is equal to or greater than the tax exemption upper limit (when the determination in step S33 is Yes), the control unit 10 in step S34, In addition, an amount of “0 yen” is input as the current tax exemption amount balance (step S34). Thereafter, the control unit 10 ends the process.

  On the other hand, when the total amount (B) of the tax exempt goods purchased on the day by the customer with the passport number is less than the tax exemption upper limit (when the determination in step S33 is No), the control unit 10 performs tax exemption in step S35. An amount obtained by subtracting the total amount (B) of the tax exempt items purchased by the customer of the passport number on the day from the upper limit amount is set as the previous tax exemption frame remaining amount (step S35).

  Next, in step S36, the control unit 10 determines that the total amount of the tax exempt goods purchased this time (A) and the total amount of the tax exempt goods purchased by the customer of the passport number on the day (B) It is determined whether or not this is the case (step S36).

  When the total amount is equal to or greater than the tax exemption upper limit (when the determination in step S36 is Yes), in step S37, the control unit 10 inputs “0 yen” as the current tax exemption amount balance (step S37). Thereafter, the control unit 10 ends the process.

  On the other hand, when the total amount is less than the tax exemption upper limit (when the determination in step S36 is No), in step S38, the control unit 10 determines in step S38 the total amount (A) of the tax exempt items purchased this time from the tax exemption limit and An amount obtained by subtracting the total amount (B) of the tax exempt goods purchased by the customer of the passport number on the day is set as the current tax exemption frame remaining amount (step S38).

<Specific examples of purchase of tax-free goods>
Next, based on FIG. 7 and FIG. 8, the specific example of the purchase of a tax exemption object is demonstrated.
7 and 8 are explanatory diagrams showing an example of a receipt printed by the printing unit 15 shown in FIG.

Here, tax exemption is applied to the same non-residents when the total sales amount of consumables per day at the same store exceeds 5,000 yen and is within the range of 500,000 yen.
Under these requirements, consider the following two cases 1 and 2.

(Case 1)
In Case 1, it is assumed that Customer A (non-resident) with passport number “1234567” purchased a tax-exempt article for 4,000 yen on that day.

Here, the amount obtained by subtracting the tax exemption lower limit from the tax exemption upper limit is 494,999 yen obtained by subtracting 5,001 yen from 500,000 yen.
On the other hand, the remaining amount of the duty-free frame will be 496,000 yen, which is 500,000 yen minus the purchase price of the tax-exempt goods 4,000 yen.
Therefore, the current tax exemption limit (496,000 yen) is larger than the tax exemption upper limit minus the tax exemption lower limit (494,999 yen), which indicates that the tax exemption requirement has not been reached (FIG. 4). (See step S9).

  Therefore, the control unit 10 indicates that the tax exemption requirement has not been reached, and the amount obtained by subtracting the tax exemption lower limit from the tax exemption upper limit from the current tax exemption limit remaining (496,000,000 yen) as a shortage amount for achieving the requirement (494 , 999,000 yen) and the purchase management number N are printed on the receipt (see step S10 in FIG. 4).

In this case, a receipt as shown in FIG. 7 is printed and output by the printing unit 15. In the part surrounded by the broken line, “PURCHASE FOR TAX EXEMPTION” indicates that the tax exemption requirement has not been reached, “YOU NEED MORE \ 1001” as the shortage amount to achieve the requirement, and “PURCHASE NO. No-1” as the purchase management number N "Is printed.

(Case 2)
In Case 2, it is assumed that Customer A (non-resident) with passport number “1234567” has purchased 25,000 yen tax-exempt goods on that day.

Here, the amount obtained by subtracting the tax exemption lower limit from the tax exemption upper limit is 494,999 yen obtained by subtracting 5,001 yen from 500,000 yen.
On the other hand, the remaining amount of the tax-free frame is 475,000 yen, which is 500,000 yen minus the purchase price of the tax-exempt goods 25,000 yen.
Therefore, the current tax exemption limit (494,999 yen) is less than the tax exemption upper limit minus the tax exemption lower limit (475,000 yen), indicating that the tax exemption requirement has been reached (FIG. 4). (See step S9).

Therefore, the control unit 10 causes the receipt of the previous tax exemption amount, the current tax exemption amount, and the purchase management number N on the receipt (see step S11 in FIG. 4).
In this case, a receipt as shown in FIG. 8 is printed and output by the printing unit 15. “LAST TIME \ 500,000” is printed as the last tax exemption limit, “THIS TIME \ 475,000” is printed as the current tax exemption limit, and “PURCHASE NO. No-1” is purchased as the purchase management number N in the part surrounded by the broken line. I understand.

In this way, when a non-resident, such as a foreign tourist, purchases tax-exempt goods at a tax-exempt store, for example, the passport number is registered, and the tax-exempt balance remaining at the store on that day is tax-exempt. By printing the number of purchases on the receipt, the duty-free product purchaser can easily know the remaining amount of the tax-free frame, and the appeal for additional purchases can be facilitated.
Further, the printing in the order of purchase makes it easy to confirm in what order the purchase has been made, and also facilitates the arrangement of receipts.

(Other embodiments)
1. In the first embodiment, it is determined whether the requirement for the tax exemption lower limit is satisfied not only for consumables but also for general goods. If the requirement is not satisfied, the printing unit 15 provides the receipt with the shortage amount. You may make it print (Embodiment 2).

  In this way, it becomes easy to grasp the shortage of tax exemption requirements not only for consumables but also for general goods.

2. A communication unit that communicates with another POS terminal 1 through a store server may be further provided to reflect the settlement result of the tax exempt goods at the other POS terminal 1 (Embodiment 3).

  In this way, in a wide store or shopping mall having a plurality of POS terminals 1 on one floor, it is possible to take over and reflect the settlement results of the tax exempt items at other POS terminals 1.

3. In the first or second embodiment, a non-resident may be specified by passing an ID card or the like holding non-resident information through a card reader (fourth embodiment).

  In this way, it is possible to easily identify a non-resident without inputting a passport number or the like from the operation unit 11.

4). In Embodiments 1 to 3, when the requirements for the tax exemption lower limit amount and the tax exemption upper limit amount are not satisfied, the control unit 10 may cause the display unit 14 to display the contents before printing the receipt. (Embodiment 5).

  In this way, before receiving the receipt, the customer can know that the customer is not eligible for tax exemption because the tax exemption requirements are not met.

As mentioned above,
(I) A POS terminal according to the present invention includes a product information acquisition unit that acquires product information by reading a product code of a product for settlement, and a memory that holds a list of duty-free items and a daily tax-exempt upper limit. A printing unit that prints receipt information to be printed on a receipt for payment, and a control unit that controls the product information acquisition unit, the storage unit, and the printing unit. Based on the product information, the list of tax exempt items and the tax exemption limit, the total amount of tax exempt items purchased by the customer and the balance of the tax exemption amount are calculated and printed on the printing unit. .

In the present invention, the “POS terminal” is an ECR (Electronic such as a cash register).
This is a device for paying for goods such as a cash register (electronic cash register) terminal and a POS (point of sales) terminal.

Furthermore, the preferable aspect of this invention is demonstrated.
(Ii) An ID input unit that should input an ID for identifying a non-resident who is tax-exempt, and the control unit is tax-exempt based on whether or not the ID is input from the ID input unit. If the customer is a tax exempt person, the total amount of the tax exempt items purchased by the customer after settlement and the balance of the tax exempt amount are calculated and printed on the printing unit. On the other hand, when the customer is not a tax exempt person, a normal checkout process may be performed.

  In this way, tax exemption processing can be performed only for non-residents who are tax exempt.

“Non-residents” are temporary residents such as foreign tourists who are eligible for tax-free sales.
“ID” is a number unique to a non-resident, for example, a passport number or the like such as a passport.

(Iii) When a customer having the same ID purchases an additional product in the same store, the control unit takes over the total amount of the tax exempted item and the balance of the tax exempted amount calculated previously, and The total amount of goods and the remaining amount of the tax exemption amount may be calculated and printed on the printing unit.

  In this way, since it is not necessary for the customer to calculate the total amount of the tax exempt goods and the remaining amount of the tax exemption amount by individually collecting the receipts, the burden on the customer is reduced.

  The “same store” is not necessarily limited to one store. For example, in the case of a shopping mall or the like, it may be composed of a plurality of stores.

  (Iv) The storage unit holds a tax-exempt lower limit, and the control unit, when the purchase price of the goods related to the settlement is less than the tax-exempt lower limit, indicates that the tax exemption requirement has not been reached and for fulfilling the requirement. The shortage amount may be printed on the printing unit.

  In this way, it is possible to perform an appropriate settlement process according to the range of the tax exemption amount.

(V) When a customer having the same ID purchases an additional product in the same store,
The control unit may include a purchase management number for specifying a purchase order of tax-exempt goods in the receipt information, and cause the printing unit to print the purchase management number.

  In this way, since the purchase order of the tax exempt goods is printed on the receipt, it is easy to manage the purchase history of the tax exempt goods.

Preferred embodiments of the present invention include combinations of any of the plurality of embodiments described above.
In addition to the embodiments described above, there can be various modifications of the present invention. These modifications should not be construed as not belonging to the scope of the present invention. The present invention should include the meaning equivalent to the scope of the claims and all modifications within the scope.
