I favor Samsung Pay. You can put credit and debit card info into it and then use your phone at the card swipe reader. Uses NFC to talk to the reader, if that's fails there are coils in the back of the phone which replicate the magnetic fields of swiping your card to the reader. Only places I've found it not to work are gas pumps where the reader is buried behind a metal wall. Always surprises people who have very old / no electronic payment card readers when it works.
