Biometric measuring apparatus for recognizing a person's identity based on measurements performed on the person's hand. An arrangement for producing (11) and storing (13) a silhouette image of at least a portion of a person's hand is combined with an arrangement for producing (11) and storing (21A) a displacement image of the same portion of a person's hand which can be correlated (30) with said stored silhouette image to provide measurement data on finger height characteristics. An analyz- ing device analyzes said stored silhouette image and said stored displacement image to produce hand feature data, including hand feature data derived at least in part from finger height characteristics. A comparing device (60) compares hand bid data with hand enrollment data to decide on the basis of prearranged decision criteria whether said hand bid data and said hand en- rollment data were produced by the same hand portion.
