One thing which I'm still missing with tap and pay :
Wouldn't it be really cool to select the bank account from which you want to pay once you have primed the phone for tap and pay?
I use tap and pay from the widget on my android home screen. The screen then displays a really large "Ready" or something like that. That would be a nice screen to select a different account for that specific payment.
Like a "pay once using this bank account" or something like that.
There is plenty of space for it on that screen and would be a really additional value for that screen I think.
