Abstract

The present invention provides an apparatus enabling the Human Interface Device (HID) to provide a smart card interface and an operating method therein. The apparatus is a virtual reader driver layer comprising a monitoring module for monitoring the connection and disconnection of the HID and obtaining the name of the HID object; a PC/SC interface module for providing a driver interface complying with the PC/SC Specification to the application layer, receiving the IRP sent from the application layer, and transmitting it to a data processing module; and a data processing module for receiving and processing the IRP sent from the application layer through the PC/SC interface module, and sending the IRP to the HID device class driver layer in accordance with the name of the HID object obtained by the monitoring module.

Claims
