Originally released on September 28, 2015, Samsung Pay is a payment app created for use with Samsung smartphones and Samsung gear wearables. It allows users to add funds, as well as credit/debit cards, to a digital wallet they can use to make purchases through various means, including tap-to-pay and online stores. Samsung Pay also offers its users rewards for making purchases.
How do I use the tap-to-pay feature for Samsung Pay?
Tap-to-pay is a feature that uses NFC to allow smartphone users to purchase goods and services. Once you've added a payment source, hold your device near the payment terminal. If it is required, you can authenticate using your fingerprint, your eyes (via iris), or by entering a PIN.
