Future Tecnology- A cellphone that knows you

From the past to now, there are many changes in technology. A cell phone that only can call now changes to a cell phone can play games. In the past ten years, the password is a credits number or a

shape. But now, the password on the cell phone is a person. Everyone is different, and everyone's touch and face are different. So, people started to make a cell phone that can detect your face and touch.When you open the cell phone, it will tell you to unlock your cell phone to use it. Now there is an A.I. detect. It can detect a person's face to unlock. It's a very future technology.

I have an iPhone 8. My touch id is set on my right thumb. When I use any of my fingers, it can not unlock. It works normally. I can only use my right side thumb to unlock the cell phone. The other detection is face id. And I use my iPhone X to set up my face id. I need to use my face to unlock the cell phone. I told my brother to try and unlock the cell phone, but it doesn't work. And I use my photo to unlock the cell phone. The cell phone recognition for five seconds, and shake that it can not unlock the cell phone. There is an idea that can test iPhone X face id isn't it perfect. This idea is to try to recognition twins' face. I have a friend that is twins. I set on his face, and let his brother unlock. No, it can not unlock. At last, I tell his brother to do the same countenance with his brother. The cell phone recognition about three seconds, and it unlocks. The impossible thing happened. The cell phone unlock. This means the twins' appearance is too similar, and it let the cell phone cannot detect this is the different person. It doesn't mean cell phone is broken. If the twins can unlock the cell phone, it will become more dangerous.

This is a movie that twins unlock the face id. At last, they do the same countenance to unlock the cell phone.

There will be many new inventions in the future. A.I. face detects and touch detects is one of them. I think there will be eye detection to unlock the cell phone, computer, etc. These future technologies let people's lives became more convenient and safe.
