Abstract

An RFID tag of one embodiment includes an RFID tag main body, in which an RFID chip and an antenna are disposed on a base material, and a retro-reflective material mounted on the RFID tag main body.

Claims

1. An RFID tag comprising:

an RFID tag main body comprising an RFID chip and an antenna disposed on a base material; and

a retro-reflective material mounted on the RFID tag main body.

2. The RFID tag according to claim 1,

wherein the retro-reflective material is superposed on the RFID tag main body.

3. The RFID tag according to claim 1,

wherein the retro-reflective material is aligned on the same plane as the RFID tag main body.

4. The RFID tag according to claim 1,

wherein the retro-reflective material comprises

a retro-reflective portion having a plurality of different display colors, and

a display color selection unit that selects a display color of the retro-reflective portion, and

the display color selection unit comprises a light shielding plate movable in an aligning direction of the retro-reflective portion having a plurality of colors and moves the light shielding plate so as to make it possible to select the display color of the retro-reflective portion.

5. The RFID tag according to claim 4,

wherein the retro-reflective portion has a first color and a second color.

6. The RFID tag according to claim 1,

wherein the retro-reflective material reflects illumination light.

7. The RFID tag according to claim 1,

wherein the retro-reflective material comprises a peelable color film on a reflecting surface.

8. An RFID system comprising:

an RFID tag comprising

an RFID tag main body comprising an RFID chip and an antenna disposed on a base material, and

a retro-reflective material mounted on the RFID tag main body;

a wireless station configured to transmit a beacon signal; and

an inspection place search device.

9. The RFID system according to claim 8, comprising a plurality of RFID tags and a plurality of wireless stations.

10. The RFID system according to claim 9,

wherein the plurality of wireless stations are configured to transmit beacon signals of substantially similar strength.

11. The RFID system according to claim 8,

wherein the retro-reflective material is aligned on the same plane as the RFID tag main body.

12. The RFID system according to claim 8,

wherein the retro-reflective material comprises

a retro-reflective portion having a plurality of different display colors, and

a display color selection unit that selects a display color of the retro-reflective portion, and

the display color selection unit comprises a light shielding plate movable in an aligning direction of the retro-reflective portion having a plurality of colors and moves the light shielding plate so as to make it possible to select the display color of the retro-reflective portion.

13. The RFID system according to claim 12,

wherein the retro-reflective portion has a first color and a second color.

14. The RFID system according to claim 8,

wherein the retro-reflective material comprises a peelable color film on a reflecting surface.

15. The RFID system according to claim 8,

wherein the inspection place search device comprises a processor, a memory, a transceiver circuit, a reception circuit, a measurement circuit, a communication circuit, and a system transmission path.

16. A method for using an RFID tag, comprising:

using light to visually identify the RFID tag, the RFID tag comprising a main body comprising an RFID chip and an antenna disposed on a base material, and a retro-reflective material mounted on the RFID tag main body;

reading an ID of the RFID tag using an inspection place search device; and

wirelessly communicating with a server to obtain contents of a repair record.

17. The method according to claim 16, further comprising:

attaching a plurality of RFID tags to portions of a bridge.

18. The method according to claim 16, further comprising:

attaching a plurality of RFID tags to portions of a tunnel.

19. The method according to claim 16,

wherein reading the ID of the RFID tag is carried out wirelessly.

20. The method according to claim 16,

wherein the inspection place search device projects light to visually identify the RFID tag.
