Soon computers and other machines will be able to remember you by looking at your eyes! The program works because everyone’s eyes are different. So in the future you won’t have to remember a number when you want to use a machine or take money out of a bank. You’ll just have to look at the machine and it will be able to tell who you are.

The eye-recognition (眼睛識(shí)別) program is already being tested in shops and banks in the USA； Britain； Spain； Italy and Turkey. Soon this technology will take the place of all other ways of finding out who people are.

However； scientists are working on other systems. Machines will soon be able to know you from the shape of your face or hand or even your smell! We already have machines that can tell who you are from your voice or from the mark made by your finger.

Eye-recognition is better than other kinds because your eyes don’t change as you get older； or get dirty like hands or fingers. And even twins have different eyes； so the program can be up to 94% correct； depending on how good the technology is. Some programs may only be 51%. In Britain； it was found that 91% of people who had tried it said that they liked the idea of eye-recognition.

In the future your computer will recognize you in the eye. So smile!
