Well that didn't take long. A few weeks' ago I mentioned how useful it would be if airports could take advantage of FaceID tech to speed up the passport check, well here you go, the first world implementation of similar tech:

Travellers departing from Dubai will no longer need to pass through any sort of security clearance counter or e-gate, they will simply walk through a virtual aquarium tunnel that will scan their face or iris using hidden cameras while they’re in motion. Dubai airport's new virtual aquarium tunnel scans your face as you walk through it

It's for departing passengers only, but I think it's a good step in the right direction.
