The airport wants to tag and track every single passenger from as far away as possible (car park? train? remote check in? home check in?) right to the gate, with every move along the way - check in, security, which shops you visit in which order, the toilets, etc. They'll use an RFID tag in your ticket or boarding card to do it, with hundreds of readers all over the site, hidden in ceilings or behind walls.
If you fart, they'll know about it.
Will it cure the massive cures at security, or the dirty tables in the cafes, or the big holes in the apron? Will it make the staff genuinely engage in delivering decent customer service rather than make passengers feel they're an inconvenience? I wonder.
