The IC card includes a proximity detection circuit that detects a proximity state to the reader/writer, a near-field communication circuit, an electronic function circuit, an electricity storage device, and a power supply control circuit. The power supply control circuit controls, based on a detection result of the proximity detection circuit, power supply from the electricity storage device to the electronic function circuit. The IC card manages and controls presence/absence and timing of power supply from the electricity storage device to the electronic function circuit and effectively controls discharging of the electricity storage device and charging of the electricity storage device."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"IC card and IC card system","description":"An IC card communicates with a reader/writer, which is inductive read/write communication equipment, in a non-contact manner.
