I usually top up online and last time I checked, the standard Myki top-up machines didn't have paywave.
Another question: basically the best way to take advantange of the "Early Bird" fee-free discount, is to for example, get up early in the morning, touch-on and then touch-off, at for example, the CBD, before 7AM. Since travel within CBD is free, I'll do my business (work or uni) until whatever time. So basically my only charge will be the return trip?
Also, anyone else think it's BS that newly bought Myki cards don't come with credit? At least banks give you new cards for free if you lose it.
I've used paywave at a 7-11 in the city once to load value onto a Myki. Worked fine.
Have you considered getting a Commuter Club Myki? Cheaper than a 5% discount and often offered with interest free installments to pay it off through your employer.
