Abstract
An interface is connectable between a main unit and an IC card and includes a data transmission path and a clock signal transmission path. The IC card receives a clock signal transmitted from the main unit over the clock signal transmission path and returns the clock signal to the main unit over the clock signal transmission path. A data transmission unit of the IC card receives the clock signal and outputs data over the data transmission path for delivery to the main unit. A data receiving unit of the main unit receives the returned clock signal and receives the data transmitted by the data transmission unit.
