  Open Your Eyes And Let's See Who You Are

  Inventors have developed a new way to identify people, using a machine that scans their eyeballs.Developed by eyes scan, this new technology takes advantage of the fact that the iris(虹膜)of each person's eye is unique, and remains unchanged throughout a lifetime.

  The process will replace ________called retina(视网膜)identification, which compared the pattern of veins(静脉)in the back of the eye.Used to control access to nuclear weapons, retina identification has never caught on with the public because it requires the user to put their eyeball right up against a lens.Iris scanning, on the other hand, works from a distance.

  The iris of the eye is photographed from up to one meter away.The patterns of the iris are translated into digital code, and stored in a PC database, along with personal information.Glasses and contact lenses do not interfere with the scanning process, and it takes only a brief moment.

  The new technology will be useful for banking and police work, as well as for the Internet economy.Before long, your computer monitor may be equipped with an iris scanner that can identify you when you shop online, thus preventing fraud.

  There will be no ID cards to carry in your pocket, and no long numbers to memorize.And eyes will be very difficult to counterfeit.

  Did you lose your ID card?No, you didn't.It's still right up there beside your nose.
