A staff member checks a passenger’s information at Mandula Port, Aug 13. The port started to enforce a new regulation during the first half of 2018 requiring staff members to retain the biometric data of foreigners aged between 14 and 70 years old. The data retained includes fingerprints to help improve the efficiency of customs clearance procedures, maintain speedy entry and exit checks, and improve management of customs services at the port.
