Xiaoshan Airport Facial-Recognition Security & One-ID Travel

Hangzhou Xiaoshan International Airport adopted Alibaba Cloud's 'ET Aviation Brain' facial-recognition identity checks in its T3 terminal from June 2018, cutting the identity-check step at security from a manual look-and-compare to about 3 seconds per passenger with a claimed 99.6%+ match accuracy; in its first month the system caught five travellers using someone else's ID. By the end of 2022 the airport extended this into full 'one-ID travel' for domestic departures — passengers check bags, clear security and board using only their ID card, without a paper boarding pass or QR code, and international departures gained electronic boarding passes in December 2024. The airport is run by the provincial Zhejiang Airport Group, not the city government.
