Airport Queuing Time Measured With Bluetooth

jones_supa writes "Helsinki-Vantaa airport has established a new method of monitoring security control queue times, utilizing phones with Bluetooth enabled. When a passenger passes through security control, the system calculates the time taken to queue and be served based on time stamps registered by the sensors. The plan is to eventually display all queuing times, which will allow busy passengers to decide whether it would be better to move to another checkpoint."

I used to travel to the USA four times a year for ten days or more per trip. I've reduced that to once or twice; cost to the US economy at least $2500 per trip (internal flights, hotels, car rental, restaurants, entertainment), because I hate being treated as a criminal. I am almost certainly not the only one, overall cost to the US economy must be in the many millions.
