As shown in FIG. 1, the information processing system 1 includes a plurality of electronic shelf labels 10 including at least electronic shelf labels 10a and 10b, an information processing server 20, and a POS terminal 30. The information processing system 1 may include a foreign currency conversion rate database ERDB. The foreign currency exchange rate database ERDB stores foreign currency exchange rates used when converting into foreign currencies of each country.

A plurality of electronic shelf labels 10 including electronic shelf labels 10a and 10b are connected to an information processing server 20 via wired or wireless communication lines. Further, the POS terminal 30 is also connected to the information processing server 20 via a wired or wireless communication line. The plurality of electronic shelf labels 10 including the electronic shelf labels 10a and 10b may be connected to each other via wired or wireless communication lines. Note that when electronic shelf labels are called collectively, they are called electronic shelf labels 10, and when a specific electronic shelf label is called, they are called by a specific code such as electronic shelf label 10a. The electronic shelf label 10, information processing server 20, and POS terminal 30 of the information processing system 1 will be explained below.

<Electronic shelf label>
FIG. 2 is a block diagram illustrating the configuration of an electronic shelf label in the information system according to the first embodiment. As shown in FIG. 2, each electronic shelf label 10 has a selection section 11, a communication section 12, a display section 13, and a control section 14. The specific electronic shelf label 10a has a selection section 11a, a communication section 12a, a display section 13a, and a control section 14a, and the electronic shelf label 10b has a selection section 11b, a communication section 12b, a display section 13b, and a control section 14b. are doing.

3 and 4 are diagrams illustrating a selection section and a display section of the electronic shelf label according to the first embodiment. As shown in FIGS. 3 and 4, the selection unit 11 is for selecting customer attributes and also for accepting customer attributes. For example, the selection unit 11 is a push button switch provided on the surface of the electronic shelf label 10. Further, the selection unit 11 may be a touch panel on the electronic shelf label 10. The customer selects customer attributes using the selection unit 11. The customer attribute is, for example, information on foreign currency that the customer desires to display. In that case, the selection unit 11 is a switch, a touch panel, or the like for selecting the display of the converted price in the foreign currency of each country.

As shown in FIG. 3, the surface or touch panel of the electronic shelf label 10 is provided with push buttons such as "Dollar conversion display" and "Yuan conversion display" as foreign currency information that the customer wishes to display. . In the state before selection by the selection unit 11, the display unit 13 displays, for example, the yen price “120 yen” (upper row of FIG. 3). When the customer presses the "Dollar conversion display" button and selects display of the converted price in dollars, the display unit 13 displays the converted price in dollars "$1" (lower row of FIG. 3).

Note that the customer attributes are not limited to the foreign currency information that the customer wishes to display, but may also be attributes related to foreign currencies such as the customer's nationality, the customer's place of residence, the customer's home country, and the debit country of the customer's credit card company. , attributes such as age, gender, and occupation of the customer that are eligible for price discounts or price premiums. The selection unit 11 can also select those attributes.

As shown in FIG. 4, for example, on the surface or touch panel of the electronic shelf label 10, pushbuttons indicating the ages of "20s," "30s," and "40s" are provided. Assume that if the customer is in his 20s, the price is set at a 20% discount. In the state before selection by the selection unit 11, the display unit 13 displays the yen price “100 yen” (upper row of FIG. 4). When the customer presses the "20s" button, the display unit 13 switches from 100 yen to 80 yen, which is a 20% discount.

When a customer attribute is selected by the customer's operation on the selection unit 11, the selection unit 11 outputs a signal SG1 including the selected customer attribute to the communication unit 12 and the control unit 14. Thereby, the control unit 14 causes the display unit 13 of the electronic shelf label 10 to display the converted price of the product converted at the predetermined conversion rate according to the customer attribute selected by the selection unit 11. For example, when the customer selects dollar display using the selection unit 11, the control unit 14 causes the display unit 13 to display the dollar price converted at the dollar exchange rate.

The communication unit 12 obtains a predetermined conversion rate from the information processing server 20 by communicating with the information processing server 20 . Note that instead of acquiring the exchange rate from the information processing server 20, the communication unit 12 may access the foreign currency exchange rate database ERDB and acquire the exchange rate from the foreign currency exchange rate database ERDB. The communication unit 12 may also access and acquire information on actual foreign exchange rates.

The communication unit 12 outputs a signal SG1 including the customer attributes output by the selection unit 11 to the information processing server 20. For example, as shown in FIG. 1, the communication unit 12a of the electronic shelf label 10a outputs a signal SG1 including customer attributes to the information processing server 20. The signal SG1 is, for example, information on a foreign currency whose price the customer desires to display. The information processing server 20 that has received the signal SG1 from the electronic shelf label 10a outputs the signal SG1 to the communication section 12b of the electronic shelf label 10b located within a predetermined range from the electronic shelf label 10a.

Similarly, when the selection section 11b of the electronic shelf label 10b is selected by the customer, the communication section 12b of the electronic shelf label 10b outputs a signal SG2 including the customer attribute to the information processing server 20. Then, the information processing server 20 outputs a signal SG2 to the communication section 12a of the electronic shelf label 10a located within a predetermined range from the electronic shelf label 10b. Therefore, the communication unit 12a of the electronic shelf label 10a receives the signal SG2 including customer attributes from the information processing server 20.

The communication unit 12a of the electronic shelf label 10a directly outputs the signal SG1 including the customer attribute outputted by the selection unit 11a to the other electronic shelf label 10b, and also outputs the signal SG2 including the customer attribute from the other electronic shelf label 10b. You may receive it directly. The communication unit 12a of the electronic shelf label 10a outputs the signal SG2 received from the information processing server 20 and the signal SG2 directly received from the other electronic shelf label 10b to the control unit 14a.

The display unit 13 displays the price of the product. On the other hand, the display section 13 switches the display under the control of the control section 14. Specifically, the display unit 13 displays the converted price of the product converted at a predetermined exchange rate according to the customer attribute selected by the selection unit 11. The display unit 13 displays the converted price of the product for a predetermined period of time, and then returns to the original display. The display unit 13 is, for example, a display screen. Note that the display unit 13 is not limited to a display screen, but may be a numerical display board as long as it can display the price of the product and the converted price.

The control unit 14 is a microcomputer or the like that controls each component of the electronic shelf label 10. The control unit 14 causes the display unit 13 to display the converted price for a predetermined period of time. The control unit 14 causes the display unit 13 to display the converted price based on the signal SG1 output from the selection unit 11 and the signal SG2 output from the communication unit 12.

When the control unit 14 receives the signal SG1 and the signal SG2, it gives priority to the signal SG1 over the signal SG2. Specifically, the control unit 14a of the electronic shelf label 10a converts the signal SG1 output from the selection unit 11a of the electronic shelf label 10a into the signal SG2 output from the information processing server 20, or the other electronic shelf label 10b. The signal SG2 is given priority over the signal SG2 output from the SG2. Therefore, the control unit 14a gives priority to the display selected by the selection unit 11a over the display selected by the selection unit 11b.

5 and 6 are diagrams illustrating displays on the display section of the electronic shelf label according to the first embodiment. As shown in FIG. 5, it is assumed that an electronic shelf label 10c is placed near the electronic shelf label 10b between the electronic shelf label 10a and the electronic shelf label 10b. On the surface or touch panel of each electronic shelf label 10a to 10c, there are provided conversion display selection sections 11a to 11c of "dollar" and "yuan" as foreign currency information that the customer desires to display. The selection units 11a to 11c are, for example, push buttons. In the state before selection by the selection units 11a to 11c, the display units 13a to 13c display prices in “yen” (upper row of FIG. 5). Note that illustration of the communication units 12a to 12c and the control units 14a to 14c is omitted.

When the customer presses the "Dollar" conversion display pushbutton in the selection section 11a of the electronic shelf label 10a and selects display of the converted price in dollars, the selection section 11a sends a signal SG1 containing information on dollar display to the communication section. 12a and the control section 14a. Then, the control unit 14a causes the display unit 13a to display the converted price in "dollars".

On the other hand, the communication unit 12a may output the signal SG1 including information in dollar representation to the information processing server 20. Alternatively, the communication unit 12a may output the signal SG1 to the communication units 12b and 12c of the electronic shelf labels 10b and 10c placed within a predetermined range from the electronic shelf label 10a. The information processing server 20 that has received the signal SG1 outputs the signal SG1 to the electronic shelf labels 10b and 10c arranged within a predetermined range from the electronic shelf label 10a.

Then, the communication units 12b and 12c of the electronic shelf labels 10b and 10c output the signal SG1 to the control units 14b and 14c, and the control units 14b and 14c display the converted price in “dollars” on the display units 13b and 13c. let Alternatively, the communication units 12b and 12c that directly receive the signal SG1 from the communication unit 12a of the electronic shelf label 10a output the signal SG1 to the control units 14b and 14c, and the control units 14b and 14c output the signal SG1 to the display units 13b and 13c. Display the converted price in "dollars". (Middle row of Figure 5).

Here, when another customer presses the "yuan" conversion display button in the selection section 11b of the electronic shelf label 10b and selects display of the converted price in yuan, the selection section 11b includes information on the yuan display. The signal SG2 is output to the communication section 12b and the control section 14b. Then, the control section 14b gives priority to the signal SG2 output from the selection section 11b over the signal SG1. Therefore, the control unit 14b gives priority to the display selected by the selection unit 11b, and causes the display unit 13b to display the converted price in “yuan”.

On the other hand, the communication unit 12b may output the signal SG2 including the original display information to the information processing server 20. Alternatively, the communication unit 12b may output the signal SG2 to the communication units 12a and 12c of the electronic shelf labels 10a and 10c placed within a predetermined range from the electronic shelf label 10b. The information processing server 20 that has received the signal SG2 outputs the signal SG2 to the electronic shelf labels 10a and 10c arranged within a predetermined range from the electronic shelf label 10b.

Then, the communication units 12a and 12c of the electronic shelf labels 10a and 10c output the signal SG2 to the control units 14a and 14c. The control unit 14a gives priority to the signal SG1 output from the selection unit 11a over the signal SG2 output from the information processing server 20 or the signal SG2 output from another electronic shelf label 10b. Therefore, the control unit 14a gives priority to the display selected by the selection unit 11a over the display selected by the selection unit 11b. Therefore, the control unit 14a causes the display unit 13a to display "dollar" until a predetermined time has elapsed.

The control unit 14c gives priority to the signal SG1 or the signal SG2 based on a predetermined priority order. For example, the control unit 14c may prioritize the signal SG2 output from the electronic shelf label 10b that is closer to the electronic shelf label 10c, or may prioritize the latest signal SG2. Therefore, the control unit 14c causes the display unit 13c to display the converted price in “yuan”.

Similarly, when receiving the signal SG2 directly from the communication unit 12b of the electronic shelf label 10b, the control unit 14a causes the display unit 13a to display "dollar" until a predetermined time elapses. The control unit 14c causes the display unit 13c to display the converted price in “yuan” based on a predetermined priority order. (Bottom row of Figure 5).

As shown in FIG. 6, when giving priority to the "dollar" display on the display section 13a, the control unit 14a enlarges the "dollar" display to be prioritized and displays the "yuan" display, which is not prioritized, in a smaller size. Good too. Further, the control unit 14a may display the "dollar" display to be prioritized above the display section 13a, and display the "yuan" display that is not prioritized below the display section 13a. Similarly, when giving priority to the "original" display, the control section 14c causes the display section 13c to display the prioritized "original" display in a larger size or above the display section 13c. Then, the "dollar" display that is not prioritized may be displayed in a smaller size or below the display section 13c.

<Information processing server>
Next, the information processing server 20 will be explained. FIG. 7 is a block diagram illustrating the configuration of an information processing server in the information processing system according to the first embodiment. As shown in FIG. 7, the information processing server 20 includes a communication section 21 and a control section 22. The information processing server 20 communicates with a plurality of electronic shelf labels 10. Specifically, the communication unit 21 communicates with the communication units 12 of the plurality of electronic shelf labels 10.

The communication unit 21 of the information processing server 20 accesses the foreign currency conversion rate database ERDB and acquires the foreign currency conversion rate from the foreign currency conversion rate database ERDB. Note that the communication unit 21 may access and obtain information on actual foreign exchange rates instead of obtaining the exchange rate from the foreign currency exchange rate database ERDB. Further, the data stored in the foreign currency conversion rate database ERDB is updated by the control unit 22 via the communication unit 21 at a predetermined frequency.

The information processing server 20 causes other electronic shelf labels 10b and 10c arranged within a predetermined range to display similar converted prices from the electronic shelf label 10a whose converted price is displayed according to the selection by the selection unit 11a. In the electronic shelf label 10a, a signal SG1 is output to the communication section 12a and the control section 14a by operating the selection section 11a. Then, the control unit 14a switches the display on the display unit 13a to display the converted price. On the other hand, the communication unit 12a outputs a signal SG1 to the information processing server 20.

As shown in the middle part of FIG. 5, the information processing server 20 that has received the signal SG1 from the electronic shelf label 10a sends other electronic shelf labels 10b and 10c, a signal SG1 is output. The signal SG1 includes customer attributes used for displaying the electronic shelf label 10a. Thereby, the control units 14b and 14c of the electronic shelf labels 10b and 10c cause the display units 13b and 13c to display the same converted price as the electronic shelf label 10a. For example, when the display of the electronic shelf label 10a is switched from a yen display to a dollar display, the information processing server 20 that has received the signal SG1 from the electronic shelf label 10a that includes the customer attribute that requests dollar display, A signal SG1 is output to the electronic shelf labels 10b placed within a predetermined range to display the dollar price.

As described above, when the display of the electronic shelf label 10a is switched by the customer's operation of the selection unit 11a, a signal is directly sent from the electronic shelf label 10a to the electronic shelf labels 10b and 10c without going through the information processing server 20. SG1 may be output. In that case, the electronic shelf labels 10b and 10c display the converted price according to the procedure shown in FIG.

<POS terminal>
Next, the POS terminal 30 will be explained. FIG. 8 is a block diagram illustrating the configuration of a POS terminal in the information processing system according to the first embodiment. As shown in FIG. 8, the POS terminal 30 includes a communication section 31, a control section 32, and a display section 33. The POS terminal 30 settles the payment when a customer purchases a product. The POS terminal 30 of this embodiment is configured to handle cases where the customer desires payment in foreign currency.

The communication unit 31 obtains a predetermined conversion rate from the information processing server 20 by communicating with the information processing server 20 . Note that instead of acquiring the exchange rate from the information processing server 20, the communication department 31 may access the foreign currency exchange rate database ERDB and acquire the exchange rate from the foreign currency exchange rate database ERDB, or may obtain the exchange rate from the foreign currency exchange rate database ERDB. Information may be accessed and retrieved.

The control unit 32 causes the display unit 33 to display the converted price of the product converted at the foreign currency exchange rate desired by the customer. The display unit 33 displays the converted price. If the customer wishes to pay in foreign currency, the clerk causes the display unit 33 to display the converted price and settles the payment in foreign currency.

<Operation of electronic shelf label>
Next, as an operation of the information processing system 1 according to this embodiment, an information processing method performed by the electronic shelf label 10 will be described. This will be explained using the electronic shelf label 10a as an example. FIG. 9 is a flowchart illustrating an information processing method performed by an electronic shelf label in the information processing system according to the first embodiment. As shown in step S11 in FIG. 9, the control unit 14a of the electronic shelf label 10a causes the display unit 13a to display the price of the product before displaying the converted price. For example, the control unit 14a displays the price of the product in yen.

Next, as shown in step S12, the control unit 14a determines whether there is a signal SG1 from the selection unit 11a. That is, the control unit 14a determines whether the customer attribute has been selected by the selection unit 11a. For example, the control unit 14a determines whether a button indicating a specific customer attribute has been pressed in the push-button selection unit 11a.

In step S12, if the signal SG1 from the selection unit 11a is YES, the control unit 14a causes the display unit 13a to display the converted price for a predetermined period of time, as shown in step S13. The converted price is the converted price of the product converted at a predetermined conversion rate according to the customer attribute selected by the selection unit 11a. After a predetermined period of time has elapsed, the display section 13a returns to its original state. Returning to step S12, the control unit 14a determines whether there is a signal SG1 from the selection unit 11a.

In step S12, if there is no signal SG1 from the selection unit 11a (NO), as shown in step S14, it is determined whether there is a signal from the outside.

In step S14, if there is a signal SG2 from the information processing server 20 (YES), or if there is a signal SG2 from another electronic shelf label 10b (YES), as shown in step S13, the control unit 14a controls the , causes the display unit 13a to display the converted price. The converted price in this case is a converted price according to the customer attribute selected by the selection unit 11b in the other electronic shelf label 10b. After a predetermined period of time has elapsed, the display section 13a returns to its original state. Returning to step S12, the control unit 14a determines whether there is a signal SG1 from the selection unit 11a.

In the case of NO in step S14, where there is no signal SG2 from the information processing server 20 and no signal SG2 from other electronic shelf labels 10, the process returns to step S11, and the control unit 14 continues to display the circle. Thereafter, the procedures of step S11 and step S12 are repeated.

<Operation of information processing server>
Next, an information processing method performed by the information processing server 20 will be described as an operation of the information processing system 1 according to the present embodiment. FIG. 10 is a flowchart illustrating an information processing method performed by the information processing server in the information processing system according to the first embodiment.

As shown in step S21 of FIG. 10, the control unit 22 of the information processing server 20 determines whether the display of any of the electronic shelf labels 10 has been changed to the converted price, that is, the selection unit 11 of any of the electronic shelf labels 10 is operated and the signal SG1 is output. In step S21, if the display on the electronic shelf label 10 has not been changed (NO), step S21 is repeated.

In step S21, if the display of one of the electronic shelf labels 10 is changed to the converted price and the selection unit 11 outputs the signal SG1 (YES), the control unit 22 outputs the signal SG1 as shown in step S22. A signal SG1 is output to other electronic shelf labels 10 placed within a predetermined range from the electronic shelf label 10 that outputs the signal. This causes the other electronic shelf labels 10 to display the same display as the electronic shelf label 10 that outputs the signal SG1. In this manner, the information processing server 20 also switches the display of electronic shelf labels 10 within a predetermined range from the electronic shelf label 10 whose display was switched by the customer.

Next, the effects of this embodiment will be explained.
In the information processing system 1 of the present embodiment, when a customer attribute is selected by the selection unit 11, the converted price of the product converted at a predetermined conversion rate is calculated on the electronic shelf label 10 according to the selected customer attribute. to be displayed. Therefore, the customer can understand the conversion price in foreign currency that the customer desires from the display of the electronic shelf label 10 that is switched according to the customer attribute. This allows travelers to easily understand the converted prices of products when shopping at foreign retail stores.

Furthermore, the information processing system 1 displays the same converted price on other electronic shelf labels 10 placed within a predetermined range from the electronic shelf label 10 for which the selection unit 11 is operated. Therefore, the customer can compare the converted prices of products around the electronic shelf label 10 for which the selection unit 11 is operated.

In addition, even if another nearby customer switches the display of the electronic shelf label 10 of another product in the retail store, the electronic shelf label 10 operated by the customer will give priority to the approximate price in the foreign currency desired by the customer. Since the converted price is displayed, you can accurately understand the converted price.

(Embodiment 2)
Next, an information processing system according to a second embodiment will be described. In the information processing system of this embodiment, the exchange rate determined by the credit card company is used as the foreign currency conversion rate instead of using the exchange rate of the exchange rate. The exchange rate determined by the credit card company may be stored in the foreign currency exchange rate database ERDB by the control unit 22 of the information processing server 20, or may be obtained by accessing the web page of each credit card company. You can.

The selection unit 11 of the electronic shelf label 10 is configured so that, as a customer attribute, it is possible to select display of the converted price in the foreign currency of each country, as well as display of the converted price at the conversion rate used by each credit card company. .

FIG. 11 is a flowchart illustrating an information processing method performed by an electronic shelf label in the information processing system according to the second embodiment. As shown in step S31 in FIG. 11, the control unit 14 of the electronic shelf label 10 displays the price of the product before operating the selection unit 11. For example, the control unit 14 displays the converted price using the conversion rate determined by the defaulted credit card company. Note that the control unit 14 may display the price of the product in yen.

Next, as shown in step S32, the control unit 14 determines whether there is a signal SG1 from the selection unit 11. That is, the control unit 14 determines whether the customer attribute has been selected by the selection unit 11. The customer attribute is, for example, an exchange rate used by a credit card company used by the customer. The customer can select a credit card company using the selection unit 11 and display the converted price at the conversion rate determined by the credit card company.

In step S32, if there is no signal SG1 from the selection section 11 (NO), the process returns to step S31, and the control section 14 continues the display as it was before the selection section 11 was operated. On the other hand, in step S32, if the signal SG1 from the selection unit 11 is YES, the control unit 14 causes the display unit 13 to display the converted price at the conversion rate determined by the credit card company for a predetermined period of time. After a predetermined period of time has elapsed, the display unit 13 returns to its original state.

Thereafter, the process returns to step S32, and the control unit 14 determines whether there is a signal SG1 from the selection unit 11. Thereafter, the procedure of step S31 and step S32 or the procedure of step S33 and step S32 is repeated.

According to the information processing system 2 of this embodiment, even when a foreign visitor to Japan uses a credit card to shop at a Japanese retail store, he or she can grasp the converted price at the time of payment by credit card. Therefore, you can know the price that will actually be debited, and you can shop with peace of mind. Other configurations and effects are included in the description of the first embodiment.
