Method for recognizing radio frequency identification tag reader and apparatus thereof

An apparatus for recognizing a plurality of radio frequency identification (hereinafter referred to as RFID) tag readers previously obtaining a protocol address, comprising:

• a request processor that requests the protocol address of the RFID reader and generates a request message including the hardware address and protocol address of the apparatus, the request message including a timestamp indicating a generation time;
• a response processor that receives and processes a response message for the request message from one of the plurality of RFID readers, the response message including the hardware address and protocol address of the corresponding RFID reader and the timestamp of the request message;
• a message table that stores information including the timestamp necessary for generating the request message;
• and
• an address table that stores the hardware address and protocol address of the RFID reader,
• wherein the response processor extracts the hardware address and protocol address of the RFID reader from the response message and stores it in the address table when the timestamp included in the response message satisfies a set condition.
