Best answer: No. Since the Gear Fit2 Pro does not contain an NFC chip, it cannot make mobile payments using Samsung Pay.

No NFC? Sadly, no Samsung Pay
Samsung's Gear S3 features the technology necessary for Samsung Pay to work. NFC stands for "near-field communication," which is generally executed by a physical chip that activates when devices are held within 4 centimeters of one another.
Unfortunately, Samsung didn't include said chip in the Gear Fit2 Pro, so Samsung Pay simply isn't possible with the tracker, even through firmware update. The physical requirements just aren't there.
If you want Samsung Pay, look elsewhere
If you really want the ability to pay with just a tap of your wrist, then you'll want to pick a smartwatch with the technology built-in. You'll very likely have to pay more, especially if it's a Samsung device, but if you want it, you want, and you have to have it.
Samsung Gear S3 Classic
You can use the Gear S3 to pay just about anywhere.
The Samsung Gear S3 is one of Samsung's best smartwatches to date, with a gorgeous screen, and tons of features. It has the great fitness tracking you want in the Gear Fit2 Pro, plus NFC and MST so that you can make payments with it at virtually any store!
