Abstract
Provided is a RFID tag with enhanced security. The tag includes a tag memory to store thereto pre-determined password information and tag data, an antenna to receive a tag data transmission request signal from an outer reader, and a tag controller to request the reader to transmit the password if the tag data transmission request signal is received, and then to transmit the tag data if the password received from the reader is identical with the pre-determined password. Accordingly, it can be prevented for a third-party, who does not know the password, to check the tag data.
