Overall Safety Score

★ ★ ★ ★ ★

Verdict: Samsung Pay offers robust security through Knox and tokenization. MST compatibility is a unique advantage. Privacy practices are standard for a large tech company but not industry-leading.

Samsung Pay is Samsung's mobile payment platform that uniquely supports both NFC and Magnetic Secure Transmission (MST), allowing it to work at nearly any card terminal. It runs on Samsung's Knox security platform.
