the world of mobile payments is still very much up-and-coming. Samsung has quite significant a advantage over many of its contemporaries in that its system operates in harmony with traditional MST (magnetic secure transmission) terminals along with NFC-enabled platforms. This, in layman's terms, means that Samsung Pay works nearly everywhere. To underline its usefulness and get more users to latch on, Sammy has rolled out a couple of welcome updates to its fledgling payment service.
As you'll see from the image to the left, Samsung Pay now supports a broader selection of membership and gift cards, while cloud integration means that all of your cards, vouchers and rewards are stored for safe-keeping.
The changelog also mentions that iris scanner authentication has been added to the fold. Unfortunately, the only Samsung device that currently includes the requisite hardware is the Note 7, the launch of which has been fraught with issues. Still, those with a safe Galaxy Note 7 will be able to verify transactions using the in-built iris scanner and if Samsung decides bake the feature into future devices, those too.
That's pretty much it for the latest Samsung Pay 2.3. If you're a Samsung Pay user, these features will no doubt prove useful -- particularly cloud sync -- so be sure to grab the update at your next convenience.
