For those who don’t know about the mobile payment service, Samsung Pay is a mobile payment and digital wallet service by Samsung that lets users make payments using compatible phones and other Samsung-produced devices. Samsung Pay is different from other payment systems, where Samsung Pay can accept not only NFC payments but other payment terminals like the usual chip or swipe terminals using a technology called Magnetic Secure Transmission, thus allowing users to pay almost anywhere.

Samsung Pay is similar to Apple Pay where for security, it digitises, uses a device-specific number and creates a random string of numbers that are unique to the transaction, thus it uses tokenization.

The service was launched in South Korea on August 20, 2015 and in the United States on September 28 of the same year. In 2016 at the International Consumer Electronics Show (CES 2016), the telecommunications company announced that Samsung Pay will be coming soon to a variety of banks in Australia, Brazil, Spain and Singapore.
