The present invention relates to a system and method for guiding the walking directions of a blind person using RFID blocks and, more particularly, to a system and method for guiding the walking directions of a blind person using RFID blocks, wherein an RFID reader wirelessly senses RF tags embedded in the blocks so as to guide walking directions by means of vibrations, buzzer sounds, and voice messages for guiding entry/exit directions, according to the types of pedestrian zones when a blind person walks along the blocks. The guiding system comprises: RFID tags for guiding the walking of a blind person; a plurality of blocks embedded in sidewalks which are divided into a junction zone block, a junction neighboring zone block and a general pedestrian zone block; a walking cane for receiving pedestrian zone information from the RFID tags in the plurality of blocks and outputting vibrations, sound effects and voice messages for guiding walking directions. The walking cane comprises: an antenna for receiving the pedestrian zone information by means of the RFID tags and a wireless transceiver; and a control part for generating vibrations when the blind person passes a general pedestrian zone block, generating vibrations and buzzer sounds when the blind person passes a junction neighboring zone, outputting vibrations and a voice guiding message for indicating a junction zone block when the blind person passes, and outputting vibrations and a voice guiding message for entry/exit directions when the blind person passes the junction neighboring zone block via the junction zone block.
