ABSTRACT:
An apparatus which is responsive to the pressure variations inherent in an individual's act of handwriting a signature for generating electrical signals representative of these characteristic pressure variations for use in signature identification systems. The apparatus employs a handwriting surface which is suspended in space and positioned for receiving a handwritten signature by a pair of cantilever arms which extend from a single semi-rigid vertical support member, the vertical support member being provided with a sensing means responsive to the varying strain induced in the support member when an individual is writing his signature on the handwriting surface for generating an electrical signal representative of the pressure variations in said signature.
