Three months after launching the Samsung Pay beta for the regular Gear S2 and Gear S2 Classic in the United States, Samsung has today introduced compatibility for the 3G/4G variant. Thanks to a recent software update, the mobile payment platform should already be installed on newly-supported models of the watch, so all you have to do to get started is hold the Back key for 1-2 seconds, then hit Start using Samsung Pay now.
Some users were reportedly asked to install an update for Samsung Pay on their smartphone and sign into their Gear S2 Beta account when following the aforementioned steps to start paying for goods using their watch. Fortunately, doing so is extremely easy and shouldn't take more than a minute. Simply open up the Gear Manager application on your smartphone and tap Update. Once that's done, select Samsung Pay Beta and plug in your details.
It’s worth noting, however, that unlike its smartphone counterpart, Samsung Pay for the Gear S2 doesn’t support magnetic strip transmission — so you’ll only be able to use the service with NFC readers. Fortunately, that shouldn't be too much of an issue as the majority of payment terminals in brick-and-mortar stores in the United States have already made the switch over to NFC from the antiquated swipe system.
