The payments app will go live with the new Galaxy S6 and Galaxy S6 edge, both also launched at the show and set to start shipping worldwide in April, with Samsung Pay at first only available in the US and Korea.
Like previous Samsung payments efforts, Samsung Pay has fingerprint authentication and for added security, like Apple Pay, the service uses tokenization, generating random numbers as a transaction ID instead of transmitting personal card details.
The multicoloured, 5.1-inch S6 and S6 edge, which comes with a mysteriously curved screen, boast the highest pixel density of any new handset, which should mean great video and picture viewing. New chipsets improve both battery performance and memory, a key battleground for winning consumers, but the specs are actually only equivalent to that of the latest iPhone.
Leaked figures reveal the cheapest Galaxy S6, with 32 GB memory, will cost €699. The Galaxy S6 edge, which is 5g lighter and has a better battery, will start at €849 with 32 GB memory.
