| 1. A card processing system comprising:
a first antenna unit set in a booth provided at a road side of a traffic lane so as to process data in an IC card with respect
to use of a toll road for a vehicle passing the toll road through a wireless communication with the IC card;
a second antenna unit set at the road side of the traffic lane outside the booth to process the data through a wireless communication
with the IC card;
a data processor to process the data relative to use of the toll road based on the card data obtained from either one of the
first and second antenna units; and
a vehicle class discriminator to identify a class of a vehicle entering into the traffic lane;
wherein the second antenna has antenna portions provided at heights corresponding to vehicle classes to be closed or touched
IC cards, and
wherein the data processor selects one of the antenna portions in response to a vehicle class identified by the vehicle class
discriminator and processes card data with respect to utilization of the toll road obtained from the selected antenna portion.
