A system utilizing a personal identification badge to collect data and to
provide access to a computer terminal. The personal identification badge
includes circuitry and transceiver components for transmitting
identification information and exchanging other digital information with a
computer terminal and other compatible devices. The personal
identification badge establishes a wireless communication link with a
computer terminal to allow a user to logon to the terminal. 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. The personal identification badge includes means
for encrypting and signing digital information. Adapted for use within a
hospital, the system provides further means for establishing an
affiliation between a personal identification badge and a patient, for
collecting digital information from electronic devices that record or
gather data regarding the status of a patient, for digitizing and
recording dictation spoken into the personal identification badge, and for
modifying the digital information so collected to conform to standards,
such as those of a Java applet or the hypertext markup language, for
interactive display on a universal display browser.
