How do I make in-store purchases with Samsung Pay?
Start by either swiping-up from the home button or opening the Samsung Pay app from your home screen. Next, select the card you want to pay with. Then, verify using your fingerprint and hover your device about ½ inch over the card reader where you’d usually swipe or tap your physical card to complete the transaction. If you prefer, you can set up Samsung Pay to use a Personal identification Number (PIN) instead of your fingerprint for verification.
