A new and useful apparatus and technique are provided for supporting a human hand in an operating environment, particularly a biometric identification system, in which imaging of the back of a person's hand, particularly the back of the person's palm, is used as the biometric identifier. Imaging the vein pattern on the back of a human hand in an operating environment that can be at least partially in the presence of ambient light, enables a biometric feature of the person's hand (e.g. the vein pattern of the person's hand) to be compared to a previously recorded digitized image of the person's hand, in order to identify the person. The present invention provides structure and techniques for imaging a human hand, with the back side of the palm facing a predetermined portion of the operating environment (e.g. the imaging device of the scanning system), and at least partially in the presence of ambient light.
