Glad about ING on iphone. Wondering if we'll get Bankwest as well, though no signs of that... yet.
Having said that, I've got a Nexus 5X, and have tried out Android Pay. I don't know about other Androids (YMMV) but I'm going so far as to say it's a superior experience to Apple Pay, at least usage wise.
Firstly the Android Pay app accepts both Credit, Debit and Loyalty cards. Yes I know there are ways you can get Loyalty cards into Apple Wallet, but not easily. After you've scanned your loyalty card, because your phone is already unlocked, then you just pay and off you go. No fiddling with the fingerprint sensor or switching apps to stocard or something, like Australians are pretty much forced to do on iphone.
When using Android Pay, you unlock the phone, and then just hold it near the reader. You don't need to hold your finger on the fingerprint sensor whilst paying. If I'm using Apple Pay, this is inevitably the time when TouchID decides it can't read my fingerprint (when it seems to work so well the rest of the time) making the entire process a bit more lengthy.
Thirdly, you can hold the phone further from the reader than you can with the iphone. Probably at least an inch and it works fine, and fast. If only bloody myki worked this well.
And of course, at least currently, Android Pay accepts more banks and cards than Apple Pay does.
Personally I think all in all it's a better experience.
