Here is my collection of Australian public transport smartcards.
The ones I’m missing are Adelaide, Canberra and Tasmania — all of which have been introduced since my last visits there.
Notably Perth’s SmartRider is the only card that is blank on the back, which is why the card number (which I’ve blacked-out) is on the front.
Some friends and family have also given me cards from overseas, though what I find most interesting is not the card designs themselves, but how the systems work for users — the response times in particular, but also the opportunities to top them up, the availability and pricing of single tickets, and so on — and to judge those, you really need to use the systems.
Expect a report on Opal soon!
