Abstract
A network router for coupling a Local Area Network to a Wide Area Network such as the Internet or an intranet includes a smart card device for receiving and reading a smart card. The smart card will include information needed for permitting the router to access the Internet or intranet, such as an access phone number, an encryption key, configuration data, and an ID and password. A specified security level can also be stored within the information on the smart card to restrict such access.
