Smart card and method that modulates traffic signaling indicative of operational attributes of the smart card and/or transactions between the smart card and USB port of a USB host

摘要

A smart card includes a card body and integrated circuit carried by the card body, including a microprocessor operative for communicating with a host and driving a signaling device indicative of smart card transactions between the smart card and a USB port of the host. The microprocessor is operative for modulating the signaling device based on operational attributes of the smart card and/or transactions between the smart card and USB port of the host.
