Claims

1. An electronic shelf label (ESL) apparatus using radio frequency identification (RFID), the apparatus comprising:

an ESL tag to be attached to a shelf; and

a radio tag reader to store, in the ESL tag, details that is received from an ESL server, in response to an article information update request from the ESL server,

2. The apparatus of claim 1, wherein:

the details is associated with an article positioned on the shelf, and

when details of the article is pre-stored in the ESL tag, the radio tag reader updates the ESL tag by replacing the pre-stored details with the details received from the ESL server.

3. The apparatus of claim 1, further comprising:

an article recognition tag comprising identification information of an article positioned on the shelf and to be attached to the article,

wherein in response to an inventory request from the ESL server, the radio tag reader obtains identification information of the article from the article recognition tag and transmits the obtained identification information of the article to the ESL server.

4. The apparatus of claim 1, wherein in response to an article information verification request from the ESL server, the radio tag reader obtains the details from the article shelf label tag and transmits the obtained details to the ESL server.

5. The apparatus of claim 1, further comprising:

a radio switching module to control switching of n communication signals between antennas attached to n shelves and the radio tag reader when the number of shelves is n, where n denotes a natural number of 2 or more.

6. The apparatus of claim 1, wherein the ESL tag comprises:

a communication unit to support a radio communication with the radio tag reader;

a memory to store the details; and

a control unit to control displaying of the details.

7. The apparatus of claim 1, wherein the ESL tag comprises, as the details, at least one of a name of an article positioned on the shelf, a place of origin of the article, a manufactured date thereof, a constituent material thereof, and price information thereof.

8. The apparatus of claim 1, wherein in response to an input of a selection button using a radio tag reader control program, the radio tag reader receives at least one of the article information update request, an inventory request, and an article information verification request.

9. An operation method of an electronic shelf label (ESL) apparatus using radio frequency identification (RFID), the method comprising:

receiving details from an ESL server together with an article information update request from the ESL server;
