　     Soon computers and other machines will be able to remember you by looking at your eyes! The programme 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) programme is 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 hands or even your smell! And machines can already tell who you are from your voice or your fingerprints(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 programme can be up to 94% correct, depending on how good the technology is. In Britain, it was found that 91% of the people said that they liked the idea of eye-recognition.
