Brit here. About eight years ago I flew from London to Belfast and return for business. We don’t need a passport to travel to Northern Ireland, just photo id like driving licence is fine.
Coming back to London I approached the gate and before I could pull out my wallet to show my id, the guard says " Good evening Mr. Codandchips have a safe journey "…
Yes they have facial recognition, the cameras are visible but you don’t notice them.
Good God, were you that security guard???
