An eGate system will be introduced at the Bandaranaike International Airport (BIA) in Sri Lanka's Colombo to allow passengers to clear immigration quickly, Immigration Controller General Pasan Ratnayake said.Ratnayake noted that around four e-gate machines would be installed at the airport in addition to the existing counters where physical checks are conducted. These systems are expected to be introduced within the next three months, reported the Sunday Times. Passengers will have to scan their passport at the e-gate machine in order to pass through, he explained adding that the machine would be linked to the INTERPOL database.This would assist in expediting the process of confirming a passenger's identity, the Immigration Controller General added.
