Abstract

An IC tag is used in combination with a base device in a non-authentic article discrimination system for discriminating whether an article to which an IC tag is attached is a non-authentic article. The IC tag includes an antenna portion for receiving a radio wave transmitted from the base device, a power generation circuit for generating electric power from the radio wave received by the antenna portion, a storing portion for storing information regarding the article, and a radio wave output circuit for outputting a radio wave including the information stored in the storing portion toward the base device via the first antenna portion.

Claims

1. An IC tag to be used in combination with a base device in a non-authentic article discrimination system for discriminating whether an article to which an IC tag is attached is a non-authentic article, the IC tag, comprising:

an antenna portion for receiving a radio wave transmitted from the base device;

a power generation circuit for generating electric power from the radio wave received by the antenna portion;

a storing portion for storing information regarding the article; and

a radio wave output circuit for outputting a radio wave including the information stored in the storing portion toward the base device via the first antenna portion.

2. The IC tag as recited in claim 1, wherein the information stored in the storing portion is a manufacturer ID code of the article.

3. An IC tag to be used in combination with a base device in a non-authentic article discrimination system for discriminating whether an article to which an IC tag is attached is a non-authentic article, the IC tag, comprising:

an antenna portion for receiving a radio wave transmitted from the base device;

a power generation circuit for generating electric power from the radio wave received by the antenna portion;

a storing portion for storing information regarding the article; and

a receiving circuit configured to receive the radio wave received by the antenna portion;

a discrimination circuit for discriminating whether the information stored in the storing portion coincides with information regarding the article included in the radio wave received by the receiving portion; and

a light-emitting diode for emitting light depending on a discrimination result of the discrimination circuit.

4. The IC tag as recited in claim 3, wherein the information stored in the storing portion is a manufacturer ID code of the article.

5. The IC tag as recited in claim 3, further comprising a computing circuit for computing the information stored in the storing portion depending on a discrimination result of the discrimination circuit.

6. The IC tag as recited in claim 4, further comprising a computing circuit for computing the information stored in the storing portion depending on a discrimination result of the discrimination circuit.

7. An IC tag to be used in combination with a base device in a non-authentic article discrimination system for discriminating whether an article to which an IC tag is attached is a non-authentic article, the IC tag, comprising:

an antenna portion for receiving a radio wave;

a power generation circuit for generating electric power from the radio wave received by the antenna portion;

a storing portion for storing information regarding the article; and

a receiving circuit configured to receive the radio wave received by the antenna portion;

a discrimination circuit for discriminating whether the information stored in the storing portion coincides with information regarding the article included in the radio wave received by the receiving portion; and

a radio wave transmitting portion for transmitting a radio wave including the information stored in the storing portion via the antenna portion toward the base device depending on a discrimination result of the discrimination circuit,

8. The IC tag as recited in claim 7, wherein the information stored in the storing portion is a manufacturer ID code of the article.

9. The IC tag as recited in claim 8, further comprising a computing circuit for computing the information stored in the storing portion depending on a discrimination result of the discrimination circuit.

10. The IC tag as recited in claim 7, further comprising a light-emitting diode for emitting light depending on a discrimination result of the discrimination circuit.

11. The IC tag as recited in claim 8, further comprising a light-emitting diode for emitting light depending on a discrimination result of the discrimination circuit.

12. The IC tag as recited in claim 9, further comprising a light-emitting diode for emitting light depending on a discrimination result of the discrimination circuit.
