Your smartphone could eventually be used to track your movement through airports with the intent to improve traffic flow through security lines and reduce wait times.
The Transportation Security Administration is looking into using small receivers that could be placed at specific checkpoints to pick up serial numbers that are automatically emitted from some electronic devices, reports USA Today.
While the technology could improve traffic inside airline terminals, it does pose some privacy problems, experts told USA Today.
In a test run of the tracking system conducted at the Indianapolis International Airport, only partial serial numbers were recorded, and they were deleted shortly thereafter, but if the technology is widely put to use in airports nationwide, that may not always be the case.
Heathrow Airport in London is already working to implement the system, USA Today reports.
