Samsung Pay is a mobile payment service for smartphones launched by the Samsung company in response to Apple Pay, working in a similar way, but offering compatibility with many more POS than Apple Pay from Cupertino.
If for Apple Pay a merchant must work with Apple to implement availability and only certain credit cards can be used together with this service, Samsung Pay is much easier to use and is compatible with many more types of POS.
In the video clip below, Samsung demonstrates how Samsung Pay can be used in a location where normally Apple Pay would not have been useful for making mobile payments, and this situation is found in many places from the USA and other areas around the globe.
