How do I pay for my purchase with Samsung Pay™?

Swipe from the bottom of the screen to the top to access your card in Samsung Pay™ and place your finger on the Home key to verify your identity (or if you’re using a Samsung Pay PIN, tap PIN and enter your 4 digit code). 
Place the back of your device close to the store’s card reader and tap NEXT to complete the purchase. 
You still may be required to enter your PIN your card’s PIN number if you’re using a Visa debit card; some merchants may prompt you to verify the total charges are correct while others will require a signature. 
If the connection is unsuccessful or too much time has passed, touch the “retry” icon at the top of the card. You will not be required to verify your identity again.
