There are a number of good live-finger detect methods beyond simple resistance and capacitance that are not easily fooled. Pulse oximetry is one. There are other extremely good methods which I can't discuss here since I'm under non-disclosure. Some scanners though are so lame that you can actually get a match from the latent print left behind on the prism by directing light onto the prism at the correct angle. --PH __________________________________________ Get Your Free Email from http://www.hotml.com
