Safer than Azkaban! When you make a purchase, Samsung Wallet uses a device-specific number and a unique transaction code. Your full card number is never stored on your device or on Samsung servers, and it can’t be shared with merchants. Samsung doesn’t keep transaction information that can be tied back to you, ensuring that all purchases are private. On top of that, it’s secured by the Knox framework, which constantly monitors and protects your device from malware.
