Abstract
A radio frequency identification (RFID) reader for offering tag related information and a method thereof are provided. The RFID reader includes a communicator which receives a radio frequency (RF) signal from an RFID tag, a controller which calculates location information of the RFID tag on the basis of the RF signal, and a display information generator which processes the location information of the RFID tag to be displayed on a display. Accordingly, even when a plurality of RFID tags are located around the reader, a user can identify the RFID tags with the identifications (IDs) of the RFID tags read by the reader.
