ABSTRACT:
A system utilizing a personal security device to provide access to a computer terminal where the personal security device includes circuitry and transceiver components for transmitting identification information and exchanging other digital information with a computer terminal and other compatible devices and the personal security device establishes a communication link with a computer terminal to allow a user to logon to the terminal so that when a user leaves the computer terminal, the communication link is terminated, causing the computer terminal to lock the keyboard, blank the monitor, and/or logoff the user if the communication link is not restored within a sufficient time period and also allowing the personal security device to facilitate subsequent computer access within a time range by providing time related access codes to the terminal that can be used to reestablish computer terminal access.
