An RFID(Radio Frequency Identification) security system and method are provided to control passage of users or articles by using RFID and to decide a security state according to the existence of the user. An RFID security system for receiving user information by RFID includes a first reader unit(200a) having a first detection zone; a second reader unit(200b) having a second detection zone; and a control unit(300) determining that the user having identification information exists in a security region if the same identification information is transmitted from the first and second reader units in order, judging that the user having identification information gets out of the security region if the same identification information is transmitted from the second reader unit and the first reader unit in order, setting a first guidance state if the user exists in the security region, and a second guidance state if not. |
