When you set up Samsung Pay, you’ll have to establish an authentication method to authorise payments (either a PIN or biometrics identifier e.g. When a payment is made at the terminal, the merchants will only see the Digital Account Number. In addition, Samsung doesn’t keep your payment information on their servers and your account details are never stored on your phone or shared with merchants. Your transactions and card information are secure. Samsung Pay requires you to authenticate every transaction.

So it's easy to detect any suspicious activity. You can keep track of all your purchases. As soon you complete a transaction, you’ll see a payment confirmation that shows exactly where the transaction occurred, along with the merchant's name and number.
