The technology, to be introduced at Moscow's Domodedovo airport by July, identifies terrorists and drug smugglers.
Thanks to "layered-voice-analysis technology" the system, developed by an Israeli company, can tell truth from lies. "We can understand that something like this could be uncomfortable for some passengers, but it is a necessary step," said Vladimir Kornilov, IT director for East Line, the airport operator.
Initially only passengers deemed suspicious by the FSB, the Russian security service that succeeded the KGB, will take the test, but it will eventually cover all passengers.
Officials said that the tests would only take between 30 seconds to a minute.
Millions of passengers travelling across Russia will soon have to take a lie detector test as part of new airport security measures, reports an Australian newspaper.
