Tipping probably has something to do with this. On US EFTPOS terminals you're prompted to add a tip/percentage/cash/okay/okay/okay/pay with card. In Australia you're given a total, the cashier sees the card in your hand, asks "Paypass?", and bang, it's done. Entire transaction is over in <10 seconds, and the only customer interaction with the terminal is waving a card over the top of it. Additionally, the lack of tipping means that people who pay with cash expect their exact change back and will wait for it, or will fish around for coins to find the exact amount, which slows down transaction processes.
