  Eye scanners tested at airport
Updated 08 February 2002, 07.02
Airport eye scanners are being tested
Futuristic eye scanners are the latest technology at one of the world's busiest airports.

A new identity system is to be tested at London's Heathrow which examines passengers' eyes instead of their passports.

Two thousand regular travellers from North America will have a picture of one eye stored on a computer.

Iris check

When they arrive in the UK they'll go into a special booth where a camera will compare the iris of their eye with the one on file.

The iris - the part around the pupil - is as unique as a fingerprint.

The new technology should take about two seconds before a barrier opens automatically.

Heathrow is the first UK airport to carry out a large-scale trial of the iris recognition technology.

It's hoped it'll make going through immigration control faster.
