Security at Your Fingertips
A new pocket device reads
fingerprints and validates
them by wireless access to a
computer. With this
biometrics system, users can
avoid using passwords, and
get simpler and more secure

High Tech Patient ID
Engineers have developed a
scanner that reads the
unique characteristics of
the veins under a person's
palm. It removes the need
for people to show
identification or relay
sensitive information like a

CSI: X-Ray Fingerprints
Ordinary invasive
fingerprinting techniques,
such as dusting, are prone
to damaging evidence.
Micro-X-ray fluorescence
images fingerprints without
touching them. By

Molding Fingerprints
Photonic crystals --
materials with precise
patterns of gaps that make
them reflect only selected
wavelengths of light --
could soon replace the
traditional ink-based
fingerprinting. In a new
