1, the RFID-based information providing system for implementing the present invention includes a mobile communication terminal 10 having an RFID tag 15, an RFID reader 20, a broker 30, An object directory service (ODS) server 40, an application server 50, and a mobile communication network 60. The mobile communication terminal 10 is provided with a mobile phone service through a mobile communication network 60 and has an RFID tag 15 itself. The RFID tag 15 is assigned to the corresponding mobile communication terminal 10 The mobile directory number (MDN).

The RFID reader 20 is installed in various places such as shops or public institutions so as to correspond to the objects 21 to be provided with information so that the RFID tags 20 of the mobile communication terminal 10 15 to transmit and receive radio frequency signals to and from the RFID tag 15 and to read the MDN of the mobile communication terminal 10 stored in the RFID tag 15. When the MDN is read from the RFID tag 15 of the mobile communication terminal 10, the RFID reader 20 transmits the reader unique code and the MDN uniquely allocated to the RFID reader 15 to the broker 30.

The broker 30 transmits the reader unique code to the ODS server 40 when receiving the reader specific code and the MDN from the RFID reader 20 and transmits the reader specific code to the ODS server 40 from the ODS server 40, uniform resource identifier (ID) and communicates with the application server 50 through the received URL to transmit the reader unique code and the MDN to the application server 50. The ODS server 40 stores the URL information of the application server 50 in which the information corresponding to the reader specific code is stored. The ODS server 40 stores the URL information of the reader 50 received from the broker 30 at the time of requesting information from the broker 30, Searches the corresponding application server URL based on the unique code and transmits it to the broker 30.

In addition, the application server 50 stores information corresponding to the reader specific code and stores the mobile communication terminal profile information corresponding to the MDN of the mobile communication terminals. The mobile communication terminal profile information includes a mobile communication terminal number, Specification information of the communication terminal, and the like. The application server 50 receives the reader unique code and the MDN that are communicatively connected to the broker 30 and is transmitted from the broker 30 and sends a callback URL containing information corresponding to the reader unique code as SMS message service to the mobile communication terminal 10 and searches the profile of the mobile communication terminal based on the MDN to retrieve the callback URL that the mobile communication terminal 10 can receive, To the mobile communication terminal (10).
