New automated technology installed at Atlanta's airport may reduce security checkpoint wait times there up to 25 percent, TSA Administrator Peter Neffenger said Wednesday.
"At some point you reach capacity with manual systems," Neffenger said during a hearing of the House Homeland Security Committee.
Instead of passengers going through security one at a time, smart lanes allow up to five people at once to fill the gray bins with personal belongings for screening.
The bins then go on an automated conveyor belt.
Smart lanes eliminate the need for passengers to stand with their bags until they disappear into the machines.
After passengers pick up their things, the bins automatically return to the start of the line.
The TSA has not said when smart lanes might be placed in other airports.
Neffenger said more automation will help relieve bottlenecks at the airport.
He said the agency is working to develop software able to detect contraband.
