Reader/writer for use with non-contact IC card and reader/writer system

摘要

A non-contact IC card reader/writer which offers an improved reliability in communication between a non-contact IC card and its reader/writer by reducing malfunction due to data communication error. The reader/writer includes a reader/writer main body electrically connected to a host machine for controlling communications, and an antenna external to and electrically connected to the reader/writer main body for transmitting and receiving electromagnetic waves to and from the non-contact IC card. Since the antenna is L-shaped in cross section, the non-contact IC card is free from right-angle antenna geometry to the antenna and maintains a good communications link with the reader/writer.
