Passengers checking into flights at Shanghai's Hongqiao International Airport can now use their face to prove their identity thanks to the rollout of facial recognition technology. The airport this week unveiled self-service kiosks for flight and baggage check-in, security clearance, and boarding powered by facial recognition technology. While many airports in China already use facial recognition to help speed up security checks, Shanghai's system is being billed as the first to be fully automated. "It is the first time in China to achieve self-service for the whole check-in process," said Zhang Zheng, general manager of the ground services department for Spring Airlines, the first airline to adopt the system at Hongqiao Airport. Currently, only Chinese identity cardholders can use the technology.
