> For contrast, Samsung Pay works by sending the bare card number to card-reader device by emulating magnetic fields. It's exactly as if you swiped the card, which is why it works with almost every card, and almost every card reader. This is incorrect. Samsung Pay uses a tokenized PAN (credit card number) over both MST and NFC. It does not transmit the original bare card number. https://developer.samsung.com/tech-insights/pay/tokenization https://developer.samsung.com/tech-insights/pay/tokenization
