RF READER, METHOD FOR PARAMETER UPGRADING THEREOF AND RF SYSTEM INCLUDING THE SAME

摘要

PURPOSE: An RF reader, a method for updating a parameter of the same, and an RF system including the same are provided to update various parameters of the RF reader by communication between the RF reader and the tag, thereby reducing costs and time for updating a parameter. CONSTITUTION: A control unit(120) outputs the second signal for an RF(Radio Frequency) parameter update mode in response to the first signal outputted from a tag(210). The first memory(130) stores update parameters transmitted from the tag in response to the second signal. The control unit updates a parameter of an RF reader using update parameters stored in the first memory.
