Doing this will charge you for an Adult Opal single trip ticket — so if you have a concession, you might want to stick with a regular Opal card for now. Plus, using your card won't cap your fare when you travel multiple times in a day or week.
Nonetheless, it's a welcome leap in technology — and one that was always going to happen at some point soon. Moving away from dedicated transport cards — or adding other payment options — will make things easier for tourists and travellers (and people who, god forbid, leave their Opal at home), who shouldn't have to buy a new piece of plastic just to catch a bus or train (or pay extra for a paper ticket if they don't) when they're visiting. However, if we're moving towards a contactless future, ensuring the new system remains accessible for anyone that doesn't have a smartphone, smartwatch or bank card remains a concern.
So what about the other cities? Melburnians can expect to scan on with a credit or debit card in trials due to start this year, focusing on Routes 11, 86 or 96, according to The Sunday Herald Sun. And in Brisbane, The Sunday Mailreports that a trial will commence either later in 2018 or sometime in early 2019, starting with the Airtrain.
