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." Link to Original Source
Never tell people how to do things. Tell them WHAT to do and they will
surprise you with their ingenuity.
