The core of intelligent entrance and exit technology lies in its identity identification and permission management system. Traditional keys have been replaced by RF cards, biometrics, and even behavioral profiling. The "non-inductive passage" system used in a high-end office building in Shanghai captures the characteristics of the enterer's gait, body shape and other characteristics through the camera, and completes the identity verification before the person arrives at the door, and the door leaf is automatically opened. This technology compresses the authentication process to near invisibility, creating a marvel of efficiency. However, beneath the cult of efficiency lies the shadow of Foucault's "disciplined society" – our physical characteristics are transformed into analyzable data that serves as the basis for the system to judge whether we are "worthy" to enter a certain space. When a visitor is turned away because the system fails to identify him, he experiences not only a technical glitch but also a grim demonstration of a new mechanism of exclusion in the digital age.

The data collected by the intelligent entrance and exit system constitutes a new cognitive map of urban space. A smart community in Hangzhou found through access control data that an elderly person living alone had not gone out for three consecutive days, and the system automatically issued an alert to the community staff, thus avoiding a possible tragedy. This kind of data utilization shows the warm side of technology. But on the other hand, these systems also record information such as the time, frequency, and number of people who come and go with each person, forming a detailed personal behavior file. Amazon's "Just Walk Out" technology is even able to track every step a consumer moves and every shelf stop in the store. When all spatial behavior becomes data points that can be analyzed, are we stepping into a panoramic and open-minded society? The "tyranny of speed" predicted by the French philosopher Paul Villilio has been interpreted in a new way - not only the speed of movement, but also the speed at which information is collected and processed, which is reshaping the boundaries of our perception of privacy and freedom.

From a more macroscopic civilization perspective, intelligent entrances and exits reflect human beings' eternal pursuit of space control. The drawbridge of ancient cities, the gates of medieval castles, and the security system of modern airports are all technical responses to the question of "who can enter" in a particular era. Today, we are experiencing a paradigm shift from physical defense to data filtering. Dubai International Airport's intelligent customs clearance system can complete passport control and facial comparison in seconds, compressing the process that traditionally took minutes into a smooth passage experience. This shift not only enhances efficiency but also redefines the nature of boundaries themselves—boundaries are no longer merely geographical lines but dynamic barriers formed by risk assessments calculated in real-time by algorithms. When a political dissident was unable to board a plane because he was listed in a database, he was met with a digital expulsion without a physical wall.

The future development of smart entrance and exit technology will face the eternal tension between efficiency and ethics. Advances in biometrics may allow us to completely move away from physical media such as keys and cards and achieve true "empty-handed access". But it also means that our biometrics will be more deeply integrated into digital surveillance networks. The EU's General Data Protection Regulation (GDPR) strictly restricts the use of biodata, demonstrating a society's vigilance against technological overreach. The ideal intelligent entrance and exit system of the future or...
