I assumed that every airport does it as a matter of policy. A border guard in the UK told me the reason they don't bother checking your passport when you leave is because they check your face on camera.

In this case it seems like a legitimate use of facial recognition: catching criminals. The story is of interest to me because i've been through the airport many times. I guess they have a picture of me.

ot but in many European airports i've been to they have those clunky face scanning machines and after that proper passport controls. I've discovered that in some places i can skip them and get my passport stamped with no issues.
