Iris scans are only the start of the souped-up technology at Dallas’ Love Field airport, which aims to make check-in a paperless, stopless process. From USA Today:

“At a terminal being renovated here at Love Field, contractors are installing 500 high-definition security cameras sharp enough to read an auto license plate or a logo on a shirt.

The cameras, capable of tracking passengers from the parking garage to gates to the tarmac, are a key first step in creating what the airline industry would like to see at airports worldwide: a security apparatus that would scrutinize passengers more thoroughly, but less intrusively, and in faster fashion than now.

It’s part of what the International Air Transport Association, or IATA, which represents airlines globally, calls ‘the checkpoint of the future.’

‘The goal is for fliers to move almost non-stop through security from the curb to the gate, in contrast to repeated security stops and logjams at checkpoints.'”
