Delta Airlines will give passengers the option to use facial recognition technology to board flights instead of using boarding passes, says a news report. 

The service would only be offered for passengers flying out of Minneapolis-Saint Paul International Airport. The facial scanners will soon be installed at 16 gates, with availability on all international flights beginning next month, says the report. 

Gate agents use facial scans to board passengers so that they don’t need to manually compare their faces and their passport photos. Delta says the process saves about two seconds per passenger or about nine minutes for a plane with 270 people.
