Samsung Electronics has launched Samsung Pay in the US following its successful launch in South Korea a month ago.
The company said that is planning to expand the mobile payments service to other markets such as China, Spain and the UK soon.
Samsung Pay only works with the Galaxy S6, Galaxy S6 Edge, Galaxy S6 Edge+ and the Galaxy Note 5 in the US.
In order to avail the service, consumers need a credit or debit card from Visa, MasterCard, or American Express card issued by Bank of America, Citi, American Express or U.S. Bank.
The payment service will allow owners of Samsung mobile devices to make purchases at contactless and magnetic stripe terminals using NFC and MST technologies.
The service uses digital tokenization, Samsung KNOX, and fingerprint authentication to provide secure payments. It is also compatible with most existing and new terminals, including most magnetic stripe, EMV and NFC terminals.
Samsung Electronics global head of Samsung Pay Injong Rhee said: "Samsung Pay works with almost any card terminal from day one and Galaxy owners can shop with a wallet they never knew was always in their hands."
