Probably from the airport scanners and cameras I see everyone gleefully sticking their faces in. A savings of several minutes per flight!

Is this common? Airport scanners are usually face scanners. Iris scanners are almost always for employees with access to critical areas, not for travelers. I know Doha and Singapore airports use iris scanners at the security check. It's probably a growing trend, haven't seen any in the EU, is it already common in the US?

Iris scanners are not hard to implement from a few meters in a controlled environment like immigration.

I would assume Iris scanners are normal - but I couldn't find anything to corroborate that for immigration control in NZ (legally they can, and I thought the equipment did, but I couldn't verify).

There used to be a scheme in the UK - https://en.wikipedia.org/wiki/Iris_Recognition_Immigration_S...

The normal TSA pre-check lines make you scan your face too. They used to read "images are deleted after use" but I didn't notice that message last time I went through security. So likely it's being used by ICE now.

The customs line have been doing much more rigorous face scanning for a while now.

TSA allowed to opt-out of this photo the last time I flew. You may also opt-out of the body scan. Nobody does.

I have a bridge to sell anyone who thinks those are deleted after use.

I bet the airports are additionally recording gait using overhead cameras.
