China continues to surprise the world with its advanced artificial intelligence (AI) and facial recognition technology. One of its most unusual innovations is the smart public toilet system that requires a face scan to dispense toilet paper.
This futuristic idea may sound humorous, but it addresses a real problem — toilet paper wastage. In many public restrooms across China, people were using excessive amounts of paper, leading to high costs and waste.
To solve this, the Chinese government and private tech companies introduced AI-powered dispensers that use facial recognition cameras. When a person approaches the dispenser, the system scans their face and releases a limited amount of toilet paper — usually about 60 cm per use.
The system records each user’s facial data temporarily, ensuring that the same person cannot get more paper within a set time frame, usually around 9 minutes. This method reduces waste dramatically while maintaining hygiene standards.
The idea first appeared in Beijing’s Temple of Heaven Park in 2017, where visitors used the smart toilet for the first time. Since then, several Chinese cities have adopted similar systems in tourist attractions, airports, and malls.
These AI smart toilets are part of China’s Smart City Initiative, a nationwide effort to integrate technology into everyday life to improve efficiency, cleanliness, and sustainability.
Many global audiences were surprised — and even amused — by this development. However, the Chinese government sees it as part of its mission to create a digitally managed urban environment that uses data for public benefit.
Privacy concerns have also been raised. Critics argue that scanning faces in restrooms could violate personal privacy. To address this, manufacturers claim that the system does not store biometric data permanently, and the images are deleted after processing.
Technically, these machines are equipped with high-definition cameras, motion sensors, and AI-based identity recognition software. They can operate offline and are designed to function even in low-light conditions.
Apart from paper dispensing, similar technology is now being explored in smart waste bins, public transport, and vending machines, showing how China integrates AI and IoT (Internet of Things) into daily routines.
Supporters say these innovations symbolize China’s leadership in AI-driven infrastructure. The system reduces maintenance costs, prevents theft, and ensures better resource management — a major concern in heavily populated cities.
Globally, no other country has implemented such widespread AI restroom management systems, making China the world leader in smart sanitation technology.
The introduction of face-recognition toilets represents more than humor — it’s a reflection of how deeply AI has penetrated everyday life in China, transforming even the simplest human habits.
In the near future, similar smart systems might appear in hotels, schools, and offices, making everyday hygiene more automated, efficient, and eco-friendly.
China’s innovation teaches a valuable lesson — when technology meets practicality, even the smallest problem can inspire world-leading solutions.
