Stations on the MRT system are divided into two areas, "paid" and "unpaid areas", which allows the rail operators to collect needed fares by restricting entry only through the fare gates, also known as "access control gates". These gates, connected to a computer network, are able to read the electronic tickets, and can store information such as the amount of time taken per trip, and the start and destination stations of each trip. This allows the rail operators to collect fares based on this information.
