Here in NZ it is literally easier to pay people via bank transfer. If I want cash I have to get a $20 out of an ATM. If I owe someone $5, I then have to get $20 out and spend some to break the $20. Or I can get their bank account, enter it into my banks phone app and bam in seconds the money is transferred, next time I have their account saved. But it wasn't that hard because they had a banking app on their phone and knew how to send it to me in an SMS.
