System for providing contents using rfid and method thereof

A system for servicing contents by using an RFID(Radio Frequency Identification) and a method therefor are provided to grant a grade for the use of contents when the contents are offered through an RFID tag, thereby servicing the contents by using the RFID according to the granted grade. A mobile RFID terminal unit(110) reads information written on an RFID tag(100) which includes information about a contents grade, extracts the information about the contents grade included in the read information, and enables a user to use contents according to the extracted grade information. An authentication server(120) receives a request for authentication in accordance with the grade information from the terminal unit(110), and responds to the request by sending authenticated results which allow the user to use or not to use the contents to the terminal unit(110). Though the authenticated results of allowing usage of the contents are received, the terminal unit(110) has to receive a predetermined password for confirming that the user is a legal user of the terminal unit(110) to use the contents in accordance with the grade information.
