“I could tell it was him by the way he walked.” If you’ve ever said that, you understand biometrics（生物识别技术）. Biometric technology is an important topic in our work and private lives. It includes the use of finger prints or knowing a person’s voice. It is the science about what a person looks like and how a person does things. Like tree leaves, no two human beings are exactly the same. They’ve got different eyes and different hair. And everyone has a different way of walking or moving.

This technology can tell you from others. At the moment if you travel through an airport, you need your ID card or passport. If you go to your bank to get some money, you need a card and a special number. But what should you do if you lose your passport or forget your number? Biometric technology can solve this problem. The technology is becoming more and more popular with old people because they no longer need to remember their passwords（密码）.

This technology is all around us in our life. We use them to unlock a smart phone, get into our homes, start our cars without a key or even pay for our shopping.

Nothing is perfect. People are worried about the safety of their private information. However, the technology will become much better in the future, and it will become more and more important in our daily life.
