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 (眼睛识别) program has been tested in shops and banks in the USA , Britain and Italy.

    Scientists are working on other systems, such as knowing you from the shape of your face or hand or even your smell! And machines can already tell who you are from your voice or your fingerprint (指纹). But eye-recognition will replace other ways of finding out who you are, it is better 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. In Britain, it was found that 91% of people said that they liked the idea of eye-recognition.
