ABSTRACT:
A reader/writer includes an input/output unit for inputting and outputting bidirectional signals from and to an external host computer, a transmitter/receiver for transmitting to and receiving from a noncontact IC card bidirectional electromagnetic-wave signals, the controller being electrically connected to the input/output unit and transmitter/receiver for transferring signals between them. The reader/writer thus assists in transferring signals between an external host computer and a noncontact IC card. The operation of the reader/writer is so simple that communication between a noncontact IC card and an external host computer can be achieved efficiently. The software implemented in the reader/writer need not be modified but can still cope with various application programs running in the noncontact IC card and external host computer.
