Abstract
A non-contact IC card system includes a non-contact IC card having a display element and an IC card reader/writer communicating with the non-contact IC card. The IC card reader/writer disables detection of a load modulated signal from the non-contact IC card when the non-contact IC card displays data on the display element.
