How long is the queue, right now
Not a sampled average from last Tuesday. A live figure accurate enough to put on a passenger-facing screen, and to trigger opening another security lane before the queue reaches the door.
Where did the dwell time go
Time recovered at security only turns into revenue if passengers spend it in the commercial area. Measuring both halves is what lets you prove the trade, which is the argument Glasgow made to its concessionaires.
Can you deploy it without a privacy review that takes a year
Ariadne captures no personal data at the sensor. There is no face, no demographic inference, and no identifier, so there is nothing to anonymise later. Identifiers are stored only when a passenger explicitly opts in, such as a guest Wi-Fi login.
This is a structural difference, not a setting. Biometric privacy statutes like Illinois BIPA and Texas CUBI regulate the capture of biometric identifiers, and a counter that never captures any gives them nothing to attach to. Operators with European terminals get the same structural answer under the EU AI Act's biometric categories.
