Abstract
A non-contact IC card can accept a frequency band different from the main receive frequency band of the non-contact IC card. The non-contact IC card has a main antenna supporting a first frequency band and an IC device connected to the main antenna for data transmission and reception. An attaching body, detachably attached to the non-contact IC card 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 is capacitively coupled to the main antenna.
