The big problem I see with MYKI is they have tried to make it too complex keeping with the zone fares. To make it easier they should have scrubbed them and made it by distance, or time or both. But in saying that the London Oyster card works on bus and trains with little problem. And the other wonderful feature is how slow it takes to register when you try to scan! I have never seen any other system that is so slow and often you have to do it a few times to register.
Why could they just not buy the London or Paris or Tokyo etc, system?
sticking to zonal fares seems a bit redundant with electronic ticketing. will be relocating there soon so will get to experience it first hand! The Opal card in Sydney suddenly doesn't seem so bad
