The feature that gives Samsung Pay ubiquity comes from LoopPay and mimics magnetic swiping. It can be used in many places where traditional credit cards can be used, but not when credit cards need to be inserted such as vending machines. This does not use tokenization or rely on NFC. Hence it's still as insecure as a traditional credit card. Samsung may incorporate tokenization, but that's outside of magentic swiping and requires NFC terminals. This is where Samsung is lagging Apple Pay. LoopPay will become obsolete on October 2015, when liability rules shift, and EMV-based machines replace older machines and chip and pin cards are mailed by banks to consumers. It's not just Mastercard and Visa (although they are responsible for the M and V in the name), but also Amex and Discover. These new machines will support tokenization and NFC. The machines may also incorporate requirements stemming from the Durbin amendment.
