Abstract
A noncontacting IC card system occupying a relatively small area without requiring a provision for a dead zone or unnecessary communication area outside a gate. A transmitting antenna 11 is provided between two contiguous gates i.e., on the inner sides of the gates, and receiving antennas are provided respectively toward the sides opposite to the transmitting antenna of the gates i.e., on the outer sides of the gates. It is thereby not necessary to provide a dead zone between the gates and an unnecessary communication area does not occur outside the gate.
