You need hands [fingerprint-based biometrics]

Advanced optics promise to transform the sometimes shaky business of fingerprint-based biometrics by overcoming various spoofing techniques. If two US-based companies, Lumidigm and Aprilis, have anything to do with it, the biometric community will find its answers in better optoelectronic design. What is surprising, is that this may involve extending the optical system beyond the detector to the actual fingerprint database and recognition system.
