FIG. 6D is a diagram showing a record structure of the store event information database 35c. As shown in FIG. 6D, the store event information database 35c stores records for each of a plurality of customer attributes, and stores store event information that introduces events held at the store in association with the customer attributes. Is done. For example, store event information “Gymnastics class for the elderly” is stored in association with the customer attribute “elderly”, and store event “esthetic product campaign for women” is associated with the customer attribute “female”. Information is stored, and store event information “Japanese cooking class for foreigners” is stored in association with the customer attribute “foreigner”.

  The store event information associated with the customer attribute “foreigner” is expressed in Japanese text information in the example shown in FIG. 6D, but in reality, the store event information is stored in a plurality of languages ( Store event information expressed in text information in English, Korean, Chinese, etc.) is stored in a record of the store event information database 35c. For example, store event information associated with the customer attribute “foreigner (Korean)” is expressed in Korean (Hangul) text information so that the display example shown in FIG. 12C can be displayed. Store event information is stored in a record of the store event information database 35c.

Some customer attributes do not have store event information. In this case, store event information is not stored in the record of the store event information database 35c for the customer attributes.
Furthermore, in this embodiment, as shown in FIG. 6D, store event information is stored in association with one customer attribute, but the present invention is not limited to this, and store events are associated with combinations of a plurality of customer attributes. Information may be stored. For example, store event information is stored in association with the combination of the age attribute “30's” and the gender attribute “female”, or the store is associated with the combination of the nationality attribute “Korean” and the gender attribute “female”. Event information may be stored.

Next, the operation in the present embodiment will be described with reference to FIGS.
First, with reference to FIG. 7, the display switching process performed by the electronic shelf label 1 will be described. In this display switching process, the CPU 10 of the electronic shelf label 1 uses the short-range communication unit 16 to change the customer's own IC card 4 to the short-range communication reading unit 16 a provided on the electronic shelf label 1. The RFID card of the IC card 4 and the customer attribute stored in the IC chip are read, the product information is switched and displayed according to the read customer attribute, and the store event information corresponding to the read customer attribute is received from the store server 3 Then, the store event information is output by voice and the store event information is switched and displayed on the display unit 12. When the IC card 4 is moved away from the short-range communication reading unit 16a, the switching display is terminated and the original display state is restored.

FIG. 7 is a flowchart showing the operation of the display switching process. This display switching process is executed under the control of the CPU 10 in the electronic shelf label 1.
First, in step S1, whether or not “card reading?” Is possible, that is, as shown in FIG. 3, the IC card 4 possessed by the customer is brought close to the short-range communication reading unit 16a provided in the electronic shelf label 1. Thus, it is determined whether or not the card can be read. If it is determined in this step S1 that the IC card 4 is not approached (step S1; NO), step S1 is repeatedly executed. If it is determined in step S1 that the IC card 4 is approached (step S1; YES), the process proceeds to step S2.

In step S2, mutual communication with the IC card 4 possessed by the customer is performed. That is, the CPU 10 of the electronic shelf label 1 transmits a request signal for requesting transmission of customer attributes to the customer's IC card 4 from the short-range communication unit 16, and the customer transmitted from the IC card 4 in response thereto. The attribute is read by the short-range communication of the short-range communication unit 16.
In step S3, the customer attribute read from the IC card 4 by the short-range communication unit 16 is stored in a predetermined memory area of the RAM 14 to acquire the customer attribute. After execution of step S3, the process proceeds to step S4.

In step S4, the CPU 10 discriminates the customer attribute stored in the predetermined memory area of the RAM 14, reads the product information suitable for the customer attribute from the product information file 15b, and stores the read product information in the predetermined memory area of the RAM 14. To do.
In the next step S5, the product information read from the product information file 15b and stored in a predetermined memory area of the RAM 14 is switched and displayed on the display unit 12. In the present embodiment, the customer attribute means, for example, the customer's age or age group, the customer's gender, the customer's nationality, or the language (Japanese, Korean, English, Chinese, etc.) used by the customer. Yes. And in this embodiment, the merchandise information suitable for the customer attribute acquired by step S3 is read from the merchandise information file 15b, and the merchandise information displayed on the display part 12 of the electronic shelf label 1 is switched and displayed.

  For example, when information indicating the customer's nationality or language used is read from the IC card 4 as the customer attribute, the product information expressed in the language used by the customer is switched and displayed on the display unit 12 of the electronic shelf label 1. . That is, in the case of a customer who uses Japanese, as shown in FIG. 11 (A), the product information expressed in Japanese is switched and displayed on the display unit 12 of the electronic shelf label 1, and the customer who uses Korean. In this case, as shown in FIG. 11 (B), product information expressed in Korean is switched and displayed on the display unit 12 of the electronic shelf label 1, and in the case of a customer who uses English, FIG. 11 (C) As shown, the product information expressed in English is switched and displayed on the display unit 12 of the electronic shelf label 1.

  Further, when information indicating the customer's age or age group is read from the IC card 4 as the customer attribute, the merchandise information is switched and displayed on the display unit 12 with the optimum display content for the customer of that age. That is, when the customer is an elderly person, as shown in FIG. 11D, the merchandise information expressed in the enlarged character size is switched and displayed on the display unit 12 of the electronic shelf label 1. In addition, when the customer is a younger age group of 30 years or younger, although not shown, detailed product information expressed in a character size smaller than the character size shown in FIG. 11A is displayed on the display unit 12 of the electronic shelf label 1. Display is switched. For example, as the product information, in addition to the product name, the production location, and the price, the producer, harvest date, advertising message, food composition table, traceability information, and the like are switched and displayed on the display unit 12 of the electronic shelf label 1.

Further, when information indicating the customer's gender is read from the IC card 4 as the customer attribute, the optimum product information for the customer of that gender is read out and switched and displayed on the display unit 12. For example, when the customer is a woman, product information configured for women is switched and displayed on the display unit 12 of the electronic shelf label 1. For example, if the product is “spinach”, the message “Appropriate spinach that is rich in vitamin A and iron and good for beauty and health” is displayed as product information to appeal the product features for women.
After execution of step S5, the process proceeds to step S6.

In step S6, the CPU 10 controls the wireless communication unit 13 to connect to the store server 3 via the communication network N2, the repeater 2, and the communication network N1. After execution of step S6, the process proceeds to step S7.
In step S7, the customer attribute read from the IC card 4 is transmitted from the wireless communication unit 13 to the repeater 2, and the customer attribute is sent to the store server 3 via the communication network N2, repeater 2, and communication network N1. Send.

  In the next step S8, it is determined whether or not the wireless communication unit 13 has received, that is, whether or not the wireless communication unit 13 has received the store event information transmitted from the store server 3. If it is determined in step S8 that the wireless communication unit 13 has not received (step S8; NO), step S8 is repeatedly executed. When it is determined in step S8 that the wireless communication unit 13 has been received (step S8; YES), the process proceeds to step S9.

  In step S9, store event information transmitted from the store server 3 is received by the wireless communication unit 13, and the received store event information is stored in a predetermined memory area (not shown) of the RAM 14. After execution of step S9, the process proceeds to step S10.

In step S10, it is determined whether or not there is store event information, and whether or not store event information is transmitted from the store server 3 to the customer attribute transmitted by the electronic shelf label 1.
Here, the store server 3 will be described later with reference to the flowchart of FIG. 9, but when store event information corresponding to the customer attribute transmitted from the electronic shelf label 1 is searched from the store event information database 35 c, Store event information is transmitted to the shelf label 1, but if the store event information corresponding to the customer attribute is not stored in the store event information database 35 c, a corresponding signal is transmitted to the electronic shelf label 1. It is configured. Therefore, the electronic shelf label 1 receives either the store event information transmitted from the store server 3 or the non-applicable signal. If it is determined in this step S10 that there is no store event information, that is, it has been received that there is no corresponding signal (step S10; NO), the process proceeds to step S13. If it is determined in step S10 that there is store event information (step S10; YES), the process proceeds to the next step S11.
