Abstract
Methods and systems are disclosed for performing a biometric function. A means is provided for positioning a hand of an individual in a substantially repeatable manner. An optical direct-imaging sensor is disposed relative to the means for positioning to image a portion of the hand when the hand is positioned by the means for positioning. A computational unit in communication with the optical direct-imaging sensor has instructions to operate the optical direct-imaging sensor to generate an image of the portion of the hand, and instructions to perform the biometric function with the generated image.
