Abstract
The present invention uses a smart control module with HID descriptors to communicate with the host side in accordance with the standard HID communication protocol, so as to interact with the smart card, which can eliminate the need of installing a private driver from a particular manufacturer when installing its reader/writer. The driver of the HID device can be installed automatically upon installation of the operating system. The users can use the reader/writer easily without carrying a driver around. It is not necessary for the users to deal with upgraded versions of the driver, to consider compatibilities of drivers for different products, to confront usage risks of the operating system due to the driver, or to worry about contamination of the operating system resulted from the installation and uninstallation of the driver.
