Abstract

A biometric scanner having an electric Held device and a method of using that scanner are disclosed. The electric Held device (a) has no electric field generator or an electric field generator that is prevented from providing an electric field to a biometric object such as a finger and (b) has an electric field sensor array comprised of a plurality of electric field sensors. Capacitance readings from the sensor array arc used to generate values that are attributed to locations corresponding to the sensors.
