It's interesting how fast you can abandon cash when you have decent alternatives. Most NZ banks support paying people to their cell phone number too, with a URL to follow to get the money. It's not that clunky either which is surprising to me (given how long decent mobile apps have taken).
It's true, and I had in the past. Then I got wary about how everything in life is recorded in a database. So, have switched back to cash for non-recurring purchases.
