ABSTRACT:
In one embodiment, a networked processor-based system is operated. Also, a non-network processor-based system is operated, wherein the networked and non-networked processor-based systems each include a security module that enables access to respective resources associated with the networked and non-networked processor-based systems. A handheld computer readable medium is received at the network processor-based system, wherein the handheld computer readable medium belongs to a first user. The networked processor-based system writes information to the handheld computer readable medium that indicates that a second user is not authorized to access the resource associated with the non-networked processor-based system.
