ACTBMS stands for ACTS “Border Management Systems”. The ACTBMS is a registration system that airport and seaport immigration officers use to register all individuals entering or leaving an island thus supporting the process of guarding the border. ACTBMS not only controls the authenticity of travel documents, but also watch lists and the process of monitoring individuals that are not allowed to enter or leave a specific island. The ACTBMS system is linked to the immigrant information system (ACTFMS) in order to indicate whether an individual must present a residence permit and to control if the permit is valid. The system also provides a day-to-day overview of the flow of passengers at seaports and airports.
