Access Granted

it may soon be harder to fool that door or safe that requires a fingerprint scan using playdoh. according to this article from acs, the current fingerprint scanning technology is fooled up to 90% of the time by a playdoh mold of a finger. but they have improved the scanning to be faked out by playdoh or dead fingers only 20% of the time by just scanning twice with 2 to 5 seconds inbetween. apparently we sweat and that changes the fingerprint a bit for live people but not other methods.
