Here's what happens if your Myki card stops working:
You have to take it to one of two locations, both in the city. That's an inconvenience of monumental stature. The city sucks for a single journey - it takes two hours out of your day even if it's a quick in-and-out, and there's nothing to do in the CBD that you can't do better in multiple other spots across the suburbs.
Once at one of their two stores, they assess if you damaged your card, or it just failed due to being made from useless cheap crap. If it is damaged, there's a $10 fee. If not, no fee. Mine was certainly not damaged, so that's fine. If I had opted on posting it in, which is such a stupid idea I didn't mention it before, they could cast judgement on it without your supervision to set them straight. It's nice to believe they'd be honest, but you really can't trust anyone these days.
After filling in a form, they give you a replacement card. However, it's empty. All your money on your old card is temporarily unavailable, so you have to spend to fill the new card again.
Though you do not lose the money from the other card (assuming your card is registered), when you get it transferred it is no longer associated with the Myki Pass (i.e. Monthly), instead it is turned into Myki Money, which is the equivalent of a Daily (more expensive). Why? Because it takes 10 working days, and by then you've not been using those days, so you get fully reimbursed. Fair enough, but TEN DAYS!???
This is ridiculous. 1) Transfer of funds should be immediate and seamless. 2) Card failure should never happen; my Credit Card and ATM Card have never failed on me, after years of use. And 3) only having a limited number of places where this assessment can happen, in less-than-convenient locations, is impractical.
For a system that cost $1.3bn or whatever it was, and was five years overdue, things as simple as replacing faulty cards should be much better handled than this.
