Orlando International has become the first United States airport to commit to using facial recognition technology.
It involves using facial biometric cameras that can be put near places like departure gates.
The cameras verify a passenger’s identity in less than 2 seconds, and they’re 99 percent accurate.
Officials say the system will be used to process the 5 million international travelers that go through the airport every year.
Facial recognition is also being tested at 13 other U.S. airports
A privacy expert expressed concern the program has no formal rules yet for handling the data.
But federal officials say they are working on those rules and they also refute that there are any privacy concerns.
