ABSTRACT:
A method and apparatus designed for verifying the identity of a person, for credit card authorization and other purposes, involves the measurement of the thickness of the knuckles and also the longitudinal distance between knuckles. The apparatus simultaneously takes a series of length and width measurements, and feeds them to a computer which is programmed to process the raw data and make comparisons to a standard previously recorded. Techniques for increasing the accuracy of the determination are also disclosed.
