Samsung Galaxy smartwatches, unsurprisingly, come pre-loaded with several Samsung apps. One such example is Samsung Pay. Even if you don't use Samsung Pay on your phone, it's a great app to set up on your watch to make mobile payments. We'll show you how.

Samsung Pay is a mobile payments service that works in the same way as Google Pay and Apple Pay. Once you've inputted a payment method, you can simply hold your smartwatch to a contactless reader to make a payment.

Samsung smartwatches work with iPhones, but Samsung Pay does not.

First, open the Galaxy Wearable app on your Samsung Galaxy or Android phone. From the "Home" tab, scroll down, and select "Samsung Pay."

Samsung will check to see if you have a compatible Galaxy smartwatch. If you do, there may be a Samsung Pay update available. Tap "Update" if that's the case.

To use Samsung Pay on your smartwatch, press and hold the Back key. After several seconds, you will be asked to add a security PIN to protect Samsung Pay. You only have to enter the PIN once while wearing the watch. If it detects you have taken the watch off, the PIN will be required again.

Once you see your card on the screen, hold the watch near the reader. You'll feel it vibrate when the payment is successful.
