"It doesn't do anything to you. There's no privacy intrusion. All it does is prevent a backflow of people," said Price, a professor at Metropolitan State University in Denver. "It's not conducting a National Security Agency check or something."

A common question among passengers is whether they are being scanned somehow while closed inside. While it is possible to equip portals with biometric scanning technology, officials say the current versions do nothing but form a barrier between the secure and nonsecure areas of the airport.

"We're not scanning anything or doing anything really," Rehmann said. "When one side's open, the other side's closed. Period."

Thompson reported from Buffalo. Associated Press writer Geoff Mulvihill contributed from Atlantic City, N.J.
