SmartRider is the contactless electronic ticketing system of the Public Transport Authority of Western Australia. The system uses RFID smartcard technology to process public transport fares across public bus, train and ferry services. The SmartRider system is designed so that passengers can "tag on" and "tag off" any services whenever they travel through the public transport network. As of 2020-21, 78.9% of all fare-paying boardings were made using a SmartRider.
