When this product information retrieval tab is activated, the purchase list communication unit 3141 can access the mart server 40.

Hereinafter, with reference to FIG. 9, a description will be made of the process of the RFID tag method for a refrigerator using the application using the system described above. The RFID tag method for a refrigerator using an application according to an embodiment of the present invention includes an RFID tag attaching step S1 for attaching an RFID tag to a product purchased by a user, a step S1 for attaching the RFID tag 10 A product inquiry step S3 for selecting an RFID tag of a desired one of the RFID tags displayed in the application 31, and an inquiry step S3 for selecting the product, And a product display step S4 in which the product information of the article is displayed on the expression unit 313 of the application.

The RFID tag attaching step S1 is a step of attaching the RFID tag 10 to the outside of the article, and the RFID tag 10 may be attached to the article, Do. In addition, there is a method of inserting into a case of a forceps, a cord, a Velcro tape or an article.

The application information input step S2 inputs and selects the product information of the products to which the RFID tag 10 is attached and a unique number of the RFID tag 10 to the information input tap of the application 31, (24), and the registered article can be placed inside the refrigerator.

The product inquiry step S3 is a step in which the user executes the application 31 and selects an RFID tag of a desired one of the RFID tags displayed in the application 31. More specifically, ), The user activates the product list tap to confirm the list of the items input in the information input step S2, and touches the product name button of the desired product. The product name button preferably indicates the product name of the product and a number peculiar to the attached RFID tag 10. It is preferable to use it from the outside where the refrigerator can not be identified mainly.

The product display step S4 is a step of activating a product information tab for confirming the product information corresponding to the touched product name button in the product inquiry step S3, An RFID tag recognition step S41 of recognizing the RFID tag 10 and transmitting the unique number of the RFID tag 10 to the communication unit 312 of the application 31 through the refrigerator management communication unit 22; And a result display step S42 for activating the information tab. In the result display step S42, the product number tab, the product name, the product purchase date, the product expiration date, and the presence or absence of the refrigerator may be displayed on the product information tab, When the unique number of the corresponding RFID tag 10 is transmitted to the communication unit 312 in the RFID tag recognition step S41, "O" meaning that the product exists in the refrigerator is displayed, and the RFID tag 10, If no unique number is transmitted, "X" is displayed, which means that the item is not in the refrigerator.

Hereinafter, with reference to FIG. 10, description will be given of another process of the RFID tag method for a refrigerator using the above-described system-based application. The RFID tag method for a refrigerator using an application according to another embodiment of the present invention includes a RFID tag attaching step S1 for attaching an RFID tag to an article purchased by a user, (S5) of obtaining product information on the purchased product (product) by communicating with the application (S3), a product inquiry step (S3) of selecting an RFID tag of a desired one of the RFID tags displayed in the application (31) And a product display step S4 in which the product information of the product selected in the product inquiry step S3 is displayed on the expression unit 313 of the application.

The purchase list information receiving step S5 is a step in which the purchase list communicating unit 3141 communicates with the mart server 40 to acquire a purchase list of the product (product) when activating the product information retrieval tab of the application 31 A purchase list information analysis step S52 for obtaining a purchase list list from the purchase list information by using the purchase list analysis unit 3142, After selecting the corresponding item in the list list box and touching the product inquiry button, the corresponding product information is confirmed, and then a unique number of the RFID tag 10 is selected in the RFID number selection box and the product information is directly inputted to the input unit 311 And a purchase list selecting step (S53) of registering the product information of the article to which the specific RFID tag 10 is attached in the refrigerator management DB 24.

Referring to FIG. 13A, in another embodiment of the present invention, when a product list tap is activated, a refrigerator number selection box appears on the top of the screen of the user terminal 30. When a desired refrigerator number is selected in the refrigerator number selection box, the items registered in the corresponding refrigerator number can be listed as a list in the product input tab, and the configuration is otherwise the same as the embodiment. The refrigerator number may be displayed on one side of the list as shown in FIG. 13B. In this case, the other configurations are the same as those of the embodiment.

Referring to FIG. 14, in another embodiment, when product information tab is activated, the product information for the corresponding product registered in the application DB 315 and the refrigerator number in which the article is located, A modification button for modifying information on the article registered in the DB 315, and a deletion button for deleting, from the application DB 315, information on the article and the refrigerator number where the article is located when the article is touched. The product information column may include an RFID number of the product, a product name, a product purchase date, a product expiration date, a refrigerator number where the product is located, and the presence or absence of a refrigerator. The communication unit 312 and the refrigerator management communication unit 22 transmit and receive radio waves to each other and the refrigerator management reader unit 21 operates to scan the RFID tags 10 existing in the refrigerator, "O" is displayed when the tag 10 is inside the refrigerator, and "X" is displayed when the tag 10 is inside the refrigerator. When touching the delete button, an OK button may be displayed on the display together with a phrase such as "Do you really want to delete? &Quot;, and when the OK button is touched, product information related to the article is stored in the application DB 24 .

Referring to FIG. 15, in another embodiment of the present invention, a refrigerator number selection box may be displayed on the screen of the user terminal 30 when activating the product information retrieval tab. Other configurations are the same as those of the embodiment, and information selected or input in the boxes displayed on the screen when the input button located at the bottom is touched is registered in the application DB 315.

In the foregoing, an optimal embodiment has been disclosed in the drawings and specification. Although specific terms have been employed herein, they are used for purposes of illustration only and are not intended to limit the scope of the invention as defined in the claims or the claims. Therefore, those skilled in the art will appreciate that various modifications and equivalent embodiments are possible without departing from the scope of the present invention. Accordingly, the true scope of the present invention should be determined by the technical idea of the appended claims.
