The office was open for business late December last year in T5. I had mine eyes checked with the system and all was well. But I couldn't get the bloody thing to read my eyes on arrival after a long flight. Even tried pulling my sleepy eyes open with my fingers but that wouldn't work either. I think the trouble is that being 6'4" I have to crouch and that's an effort. So if there is a new method I'm up for it!
