Yes this reads like vacuous AI slop and and the **randomly bolded** text everywhere is a **dead giveaway**. At this point it's becoming a stronger signal than em-dashes.
Border guard was wrong. UK used passenger records from transport companies to determine when someone left the country, not face recognition.
They do however use face recognition when you take a domestic flight from an international terminal. Then they take a photo of you just before security and compare that when you board. To me this seems like an overly complex solution to a problem that would normally by solved by having a domestic section of the terminal, but I’m sure they had their reasons.
