As per the information that we've received, Samsung is planning to launch Samsung Pay in China, Spain, and the UK in the first quarter of 2016. Currently, only five Samsung devices – the Galaxy S6, the Galaxy S6 edge, the Galaxy S6 edge+, the Galaxy Note 5, and the Gear S2 – but the Gear S2 only supports NFC payments.
Samsung uses MST technology, which mimics card swipes at regular checkout equipments to make payments, in Samsung Pay-enabled smartphones. The company acquired LoopPay for $250 million to use this technology. It is competing with Apple Pay, Android Pay, and CurrenC for supremacy in the payments service market.
