A writing instrument that incorporates a first microprocessor within the writing instrument structure, wherein the first microprocessor incorporates the smart card technology, and is capable of transmitting, receiving, processing, and storing signals and other pertinent data. In one embodiment, the first microprocessor internally stores an encrypted PIN for the writing instrument owner. The writing instrument can also incorporate biometric sensors and a second microprocessor to control the biometric sensors and collect biometric data during a signature event. The internally stored and encrypted PIN can be transferred to other systems with biometric information to provide a dual verification scheme. In another embodiment, data stored on the first and/or second microprocessor can be accessed by a reader requiring a PIN input from a user. In another embodiment, a PIN can be written with the writing instrument, and the second microprocessor is subsequently provided biometric data to verify the PIN stored in the first microprocessor and authenticate the user biometric data. The chip information may be displayed on an optional display incorporated into the writing instrument, or on a remote display.
