The present invention relates to a Braille block RFID tag for walking guidance for a visually impaired person, which enables an RFID reader to wirelessly sense the RFID tag mounted on a Braille block and lead the visually impaired person to the destination when the visually impaired person walks along the Braille block. The present invention also relates to a method for manufacturing the Braille block RFID tag. According to the present invention, the Braille block RFID tag for walking guidance for a visually impaired person enables the RFID reader to sense the RFID tag even when a cane strays from the Braille block by a distance of 5 cm or more while the visually impaired person swings the cane in the upward, downward, left or right directions and the cane is not close to the Braille block, wherein the Braille block RFID tag comprises: a PCB (15), which has a thickness of 0.32 mm and which has an upper surface on which an antenna (12) and an RFID chip (14) are mounted; transparent PVC films (16a, 16b) thermally bonded to the upper and lower surfaces of the PCB (15), respectively, up to a thickness of 0.05 to 0.1 mm; white PVC films (17a, 17b) thermally bonded to the respective transparent PVC films (16a, 16b) up to a thickness of 0.01 to 0.2 mm; transparent PVC films (18a, 18b) thermally bonded to the respective white PVC films (17a, 17b) up to a thickness of 0.01 to 0.2 mm; said antenna (12), in which the starting points of two strands of coils are connected together, and the two strands start from the respective starting points, pass through the center of the PCB (15), and are wound outwardly or inwardly along the periphery of the PCB (15) by three turns (six lines) in parallel, and the ends of the two strands are connected together so as to form a loop-shaped coil on the PCB (15); and said RFID chip (14), which is electrically connected to the starting point and to the ending point of the antenna (12), and mounted on the PCB (15) such that the RFID chip (14) overlaps with the antenna (12). The Braille block RFID tag of the present invention is advantageous in that the RFID reader for a visually impaired person senses the RFID tag and leads the visually impaired person to the destination if the distance between the cane and the RFID tag does not exceed 15 cm, even when the cane strays from the Braille block by a distance of 5 cm or more while the visually impaired person swings the cane in the upward, downward, left or right directions and the cane is not close to the Braille block. |
