Abstract
Apparatus used in identifying a person by means of pressure patterns and X-Y movements of a stylus associated with a signature includes first and second spaced and parallel planar conductor means with an excutcheon means for defining on an exposed surface of one of the elements to provide a writing surface for a user who, by means of a stylus, exerts a varying pressure pattern via the lamina onto one of the elements to produce a varying capacitance signal while at the same time interrupting light paths to produce X-Y coordinate signals.
