Conduent Transportation has installed a new contactless open payment system on the Adelaide tram system overseen by the South Australian Public Transport Authority (SAPTA). This six-month pilot programme started on 20 September. Adelaide travellers can now use their Visa, MasterCard and NFC-enabled smart devices to pay for their fares on the 24 trams throughout the city. Adelaide is the fifth largest city in Australia, with a population of approximately 1.4 million.
