Abstract

This invention has as its object to allow a-non-contact IC card to accept a frequency band different from the main receive frequency band of the non-contact IC card. The invention has a non-contact IC card which has a main antenna supporting a first frequency band and an IC device connected to the main antenna to perform data transmission and reception processing and an attaching body detachably attached to the non-contact IC card which has a sub-antenna supporting a second frequency band different from the first frequency band. When the attaching body is attached to the non-contact IC card, the sub-antenna can be capacitively coupled to the main antenna.

Claims

1. A non-contact IC card system comprising:

a non-contact IC card which has a first antenna supporting a first frequency band and a circuit connected to the first antenna for performing data transmission and reception processing; and

an attaching body detachably attached to said non-contact IC card which has a second antenna supporting a second frequency band different from the first frequency band,

wherein the second antenna can be capacitively coupled to the first antenna when said attaching body is attached to said non-contact IC card.

2. The non-contact IC card system according to claim 1, wherein said attaching body is a case which can store said non-contact IC card.

3. The non-contact IC card system according to claim 1, wherein said attaching body is a plate which can be stuck on said non-contact IC card.

4. The non-contact IC card system according to claim 1, wherein each of the first antenna and second antenna is a plate-like conductor, and when said attaching body is attached to said non-contact IC card, the first antenna and second antenna are arranged such that the first antenna and second antenna at least partially oppose each other.

5. The non-contact IC card system according to claim 4, wherein said attaching body is a case which can store said non-contact IC card.

6. The non-contact IC card system according to claim 4, wherein said attaching body is a plate which can be stuck on said non-contact IC card.

7. An attaching body for a non-contact IC card detachably attached to a non-contact IC card which has a first antenna supporting a first frequency band and a circuit connected to the first antenna, for performing data transmission and reception processing,

wherein:

the attaching body has a second antenna supporting a second frequency band different from the first frequency band, and the second antenna can be capacitively coupled to the first antenna when the attaching body is attached to the non-contact IC card.

8. The attaching body for a non-contact IC card according to claim 7, wherein the attaching body is a case which can store the non-contact IC card.

9. The attaching body for a non-contact IC card according to claim 7, wherein the attaching body is a plate which can be stuck on the non-contact IC card.

10. The attaching body for a non-contact IC card according to claim 7, wherein each of the first antenna and second antenna is a plate-like conductor, and when the attaching body is attached to the non-contact IC card, the first antenna and second antenna are arranged such that the first antenna and second antenna at least partially oppose each other.

11. The attaching body for a non-contact IC card according to claim 10, wherein the attaching body is a case which can store the non-contact IC card.

12. The attaching body for a non-contact IC card according to claim 10, wherein the attaching body is a plate which can be stuck on the non-contact IC card.
