"With the new system, the authorities are using a hand-held scanning device
that can check a prisoner’s identity in seconds
"The technology uses high-resolution images to identify unique patterns in
the iris, the colored part of the eye. It is considered less intrusive than
retinal scanning, which looks at patterns in the blood vessels in the back
of the eye and can reveal information about a person’s health, raising
privacy concerns.

"some airline pilots are engaged in their own protests against the body
imagers * * * [whose] union’s main concern is the potential cumulative
effects of repeated exposures to radiation.
"The pilots are being heard. [Transportation Security Administration] would
meet Tuesday with pilots’ representatives and airline security officers to
discuss new procedures that could allow pilots to avoid the intensive
screening that passengers receive. Doing that would require a pilot to have
a foolproof form of identification like cards encoded with their
fingerprints and iris scan. |
