TOKYO -- Japan's three main international airports will start using facial recognition to streamline security checks and the boarding process starting in 2020, cutting wait times ahead of the Summer Olympics in Tokyo.
Starting in the spring, passengers will be able to register their ticket and passport information into a special system at check-in at Narita and Haneda, the main airports serving the Tokyo area, as well as at Kansai Airport near Osaka. This means they will no longer have to show these items at security checkpoints and boarding gates.
