Do you know what travel be like in the year 2070? It is smart and easy. Here are some amazing predictions (预测).
In the airport
We don't need to check our passports. You can use "heartbeat (心跳) passports". Everyone's heartbeat is different. It can tell who you are.
On the fight
Plane scats can fit your body shape, size and even temperature (体温).
In the hotel
You don't need to bring your clothes. When you get to the hotel, you can 3D print (打印) recyclable (可再循环的) clothes in your size.
