Samsung Pay is off to a promising start... if you ask Samsung, at least. The company reports that Samsung Pay picked up 5 million users in its first six months, handling over $500 million in purchases over that time frame. There's a "strong adoption rate" in both South Korea and the US, Samsung adds. That doesn't sound like a big number on a global scale, but Samsung is teasing a 2016 expansion that now includes Canada alongside already-announced arrivals in Australia, Brazil, China (now due in March), Singapore, Spain and the UK. The future sounds bright, then, although the figures leave some unanswered questions about whether or not Samsung can keep the momentum up.
