There are also many ways tolls can be collected. In the first toll roads, you had to stop at a booth along the road and pay the toll to a person, called a "collector". Depending on the road, you might have to do so when you get on, when you get off, or both. Because many vehicles may be waiting to pay the toll, the area around "toll plazas", which are a bunch of booths blocking the whole road, can be crowded. Recently, there are roads that have "electronic toll collection", which makes use of computer chips and RFID technology to identify drivers and charge their tolls on their bank accounts.
