The new Smart e-Gate system, installed across all Dubai International\'s immigration entry and exit points is easy to use, fast and efficient, according to a senior official from Dubai residency department. Colonel Khalid Nasser Al Razooqi, Director-General of the e-Services sector at the General Directorate of Residency and Foreigners Affairs (GDRFA) in Dubai, told Gulf News yesterday the Smart e-gate is a new technology that allows a faster and more convenient movement of the growing number of passengers through Dubai airport, the world\'s fourth busiest.\"The new e-Gate helps to get rid of the need for prior user registration with the GDRFA, which is the case with the existing e-Gate card,\" said Colonel Al Razooqi. He said the new system quickly scans and reads passport information and captures biometric data including facial recognition and retinal scans using a high-accuracy camera. The system then matches the traveller\'s captured biometrics and passport information against existing lists to detect any potential immigration issues.
