Bangladeshi holders of electronic passports, or e-passports, were able to complete immigration formalities in just 18 seconds, without facing immigration police, after the launch on Tuesday.

Group Captain Muhammed Kamrul Islam, executive director of the airport, said the e-gate was fully opened after some travellers were verified through the gates experimentally on Monday.

He said 12 e-gates have been set up at departure and three at arrival.
