Abstract
An identification tag (100) facilitates use of a secure computer system (300). The tag (100) is adapted to be worn on a user'"'"'s wrist and includes an identification and registration circuit (102) that includes an identification component (106), an affiliation component (110), and a light-emitting diode (112). The computer system includes an RF identification tag registration device (302) operable to acquire user physical information and communicate the physical information to a computer (202), wherein the computer verifies that a valid user is wearing the tag (100). The identification and registration device (302) ensures that the physical information communicated to the computer pertains to the user wearing the tag by comparing pulse signals acquired from the user'"'"'s hand and wrist as the device (302) is acquiring physical information. The computer (202) uses the identification information and the affiliation information to log the user into and out of the system (300), and to associate the identification information with a particular user.

16. A wrist tag for communicating identification information to a computer, the wrist tag comprising:
-
a passive RF identification component for storing a user identification number and communicating the number in a radio signal in response to an interrogation signal;
an affiliation component for detecting when the wrist tag is secured to a user'"'"'s wrist by measuring a capacitance between two points of a surface of the tag that is in contact with the user'"'"'s skin, and for communicating affiliation information in a radio signal wherein the affiliation information indicates whether the wrist tag is secured to the user'"'"'s wrist;
a light-emitting diode for communicating an infrared tag confirmation signal; and
an attachment component for containing and securing the identification component, the affiliation component, and the diode to the user'"'"'s wrist, the attachment component including a flexible strap adapted to encircle the user'"'"'s wrist. - View Dependent Claims (17, 18)
