Apple Inc. has made mobile payments look easy, after a decade of mostly failed experiments by banks, telecom operators and retailers to woo consumers away from cards and cash.
Apple Pay has taken the United States by storm since its launch in September, and the company has said it already accounts for around $2 out of every $3 spent using "contactless" payments on the three big U.S. card networks.
But the tech giant will need a whole lot more magic as it looks to extend the service to international markets.
