Like other mobile payments services, Samsung Pay™ is more secure than using a regular plastic debit or credit card to make purchases. When you make a purchase with Samsung Pay™, your card number and information is never sent to the merchant. Instead, a “token” takes the place of your account number for each purchase. The “token” is the number used to complete your transaction, so your real card information is never used. Payments are also only authorized by your fingerprint, iris or PIN, and Samsung uses their Samsung Knox technology to monitor your phone and data. This provides a few layers of security so your information is always safe.
