Abstract
A radio frequency identification reader and a radio frequency identification tag that use an ultrahigh frequency band, and action methods of the radio frequency identification reader and the radio frequency identification tag. The radio frequency identification reader includes: a data generator generating data to be transmitted to a radio frequency identification tag; if a command to control the radio frequency identification tag has to be authenticated, a reader controller controlling the data generator to generate the data including an authentication code; and a reader transmitter transmitting the data to the radio frequency identification tag. As a result, securing of communications of a specific command between the radio frequency identification reader and the radio frequency identification tag can be reinforced.
