From an ICTSI news release published at the American Journal of Transportation:
International Container Terminal Services, Inc., (ICTSI) the largest port operator in the Philippines has rolled out at the Manila International Container Terminal (MICT) the online container booking system, the Terminal Appointment Booking System (TABS).
Booking an appointment can be done within minutes through three simple steps. After logging in, port users need to upload their container details in the system. The next step is to search for available booking slots within the given time zones, with users having 15 minutes to select their desired zones for each container. Once all the details have been reviewed and finalized, users can then proceed to confirm their appointment.
