Outside of the US, Chip & Pin is king. In many parts of Europe, you can't even use a card that doesn't have a chip. No chip, no pay.
In Australia, for purchases under $100, you use Paypass/Paywave. Simply tap and go.
Coin is a cool idea, but it's stillborn. It would have been cool 10 years ago, but the world moved on.
