ABSTRACT:
A method of preventing theft or unauthorized use of a computer including a radio frequency identification (RFID) tag allowing use of the machine only within range of the tag and when the tag is recognized. Moving or accessing the computer without the tag in range activates a security system. The computer provides a continuous authorization signal and monitors for a received signal indication of a valid response from the RFID tag. Access is denied unless a valid response is received to the authorization signal. Upon receipt of a valid response, the computer is enabled, in particular enabled to create images on paper, on screens, or to be stored in memory.
