1. Can I currently use Samsung Pay?
At the time of publishing this article, Samsung pay supports the Galaxy Note 5, Galaxy S6 edge+, Galaxy S7 and the Galaxy S7 edge provided the phones have been updated to Android Marshmallow. I won’t be surprised if Samsung rolls out this feature on future releases of mid-range mobiles (the Galaxy A and J series) as well because they will definitely want to increase the number of registered users.
The list of supported banks and cards is steadily growing. In Singapore, Samsung Pay currently supports Visa and MasterCards from DBS, CitiBank, OCBC and Standard Chartered.
I have personally missed the American Express the most because that card is my daily driver. But Samsung claims that Amex support is coming soon to Singapore. It already works in certain other geographies. So there is hope.
The list of supported banks in US and South Korea is significantly higher.
It is currently operational in the United States, Korea, China, Australia, Spain and Singapore. Canada and the UK are expected to get Samsung Pay before the end of the year. If you are not in one of these countries, you might have to wait till 2017 before you get to use it.
