Positioned at the center of the system is a stylus with any of a number of biometric properties or their combination or with one or more metric sensors, while the customer uses the stylus to sign his/her name, or even for writing anything. The identity verification system is used at point-of-sale terminals, in various closed environments, to access a computer network, in applications involving pen-based computers and smart-pens, and for e-commerce. When fingerprint sensors are used, the sensors are positioned in the stylus grip, one sensor for the index finger, and a second sensor for the thumb. In one variation, one-to-one biometric matching is used. Each participant carries on his/her person a device that includes an encrypted biometric for reference purposes to gain access Into the system. Processing is simplified since the system need only make a �MATCH� or �NO MATCH� decision. In a second variation that is particularly useful in closed environments, one-to-many biometric matching is used. During each event access request, the community of reference prints is searched for a match with the applicant. Each member of the community need carry nothing on his/her person to participate in the system. In either variation, the stylus is either attached to each site or is portable, one such stylus being carried by each participant.

The dc-capacitive fingerprint sensors from ST Microelectronics and Veridicom comprise of rectangular arrays of capacitors on a silicon chip. One plate of the capacitor is the finger to be sensed; the other plate is a small area of a pixel disposed upon the surface of the chip. The finger is positioned against the surface of the chip �actually, against an insulated coating on the surface of the chip. The ridges of the fingerprint are close to the nearby pixels and have high capacitance. The valleys are more distant from the pixels nearest them and have lower capacitance. The sensor then draws a fixed charge from each pixel in turn�that is, it scans the pixels. A high voltage appears on pixels to which the finger has low capacitance, and a low voltage appears on pixels to which the finger has a high capacitance.
In still another preferred embodiment of the identity verification system of the present invention 10, other sensors are added to the stylus 15, as necessary, to tighten security and reduce fraud�including a pressure sensor to measure point pressure; another pressure sensor to measure grip pressure; an accelerometer to the stylus point to measure stroke speed; a gyroscope positioned at the top end of the stylus 15 to measure the angle of the stylus 15; a heat sensor in the stylus grip 30 to measure position of the index finger relative to the point; and a position sensor in the stylus grip 30 to measure the position of the thumb relative to the index finger.
