Samsung Pay is certainly something worth watching out for. The service which was announced alongside the premier Samsung products — the Galaxy S6 and the S6 edge — earlier this year seems to be close to getting ripe for a couple international markets.
From what we're hearing, Samsung Pay will be heading for the South Korean and US markets later this year. Of course, we've been provided no timeline as yet; but if our sources are correct about this, we are looking at a September release timeframe… which means there's just about four months to go before that.
What makes Samsung Pay attractive is the fact that it'll be compatible with a lot of older terminals, something which isn't really possible on the prime competitor that it faces — Apple Pay.
