A radio frequency identification (RFID) used for the security function of a portable storage device includes a radio frequency transceiver and an electronic tag. The radio frequency transceiver is installed in the portable storage device, such that if a user wants to read data in the portable storage device through a computer system, the radio frequency transceiver will transmit an interrogation signal to search for an electronic tag within a signal receivable range. After the electronic tag receives the interrogation signal, it will transmit a response signal to the transceiver for performing an authentication to confirm whether or not the user has the right of reading the data in the portable storage device.
