Samsung Pay - Security
Card and transaction protection
Pay confidently from your phone knowing that the same fraud protection you bank gives your credit and debit card carries over to Samsung Pay. And since Samsung Pay doesn't store or share your payment information, every purchase is yours alone.
User authentication
Every transaction is authenticated by your fingerprint or pin number. If your phone is lost or stolen, you can remotely lock or erase your Samsung Pay account.
Data security
Tokenization creates a unique randomized set of numbers to be used at each new transaction, so your real card number isn't used.
An extra layer of defense
Samsung Knox technology constantly monitors your phone to help keep your information safe. Your card information is encrypted in a seperate and secure data vault at all times.
