With the appearance of artificial intelligence robot, the Ali cloud ET City brain, the driverless technology, the Panasonic "CityNow", the Amazon Go unmanned convenience store and other new technologies and new things, the development of the Smart City has made another step forward. Some science fiction scenes that can only be seen in movies have appeared in real life now. The city life is becoming more and more magical and efficient. When people pass through the entrances/exits of various occasions and wander around the world of science and technology by “swiping” their faces, they’re enjoying the “smart entry” of the smart city, which is really amazing.
