Hangzhou's airport cut identity checks to 3 seconds with facial recognition in 2018, then went further: by 2022 domestic passengers could clear security and board using only their ID card — no boarding pass, no QR code.

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.

Live 📅 since 2018

📊 Impact

Identity check time cut to ~3 seconds per passenger versus manual comparison, claimed accuracy above 99.6%; caught 5 people travelling on someone else's ID in the technology's first month at T3 (2018); full domestic 'one-ID' coverage achieved by end of 2022.

🎓 Lesson

The two numbers that make this sound impressive come from opposite ends of the evidence scale. The three-second check is an observable throughput figure the airport and its supplier both report; the 99.6% match accuracy is a supplier specification, and no false-match or false-reject rate has been published for the deployed system, so there is no way to say how often a passenger is wrongly stopped. The second thing worth naming is who owns it: the airport belongs to the provincial Zhejiang Airport Group, so the city's most-cited facial-recognition installation is not run by the city at all.
